Make sure the fryer is configured for the proper elevation.Record your fryer model, device, and serial numbers for future reference in the space provided below. This information can be found on the fryer data plate.Model No: ___________________Device: ______________________Serial No: ____________________Clearances☆Minimum clearance from combustible construction:6” (15 cm) from the sides of the fryer 6” (15 cm) from the back of the fryer The fryer may be installed on combustible floors☆Minimum clearance from noncombustible construction:0” from the sides of the fryer 0” from the back of the fryer☆Between the fryer and any open-top flame units:16” (41 cm)Location☆ Install fryer in an area with sufficient air supply for gas combustion at fryer burners.☆ Do not obstruct the flow of combustion and ventilation air.☆ Provide adequate clearance for air openings into the combustion chamber.☆ Do not permit fans to blow directly onto fryer.☆ Avoid wall-type fans, which create cross-currents within a room. Avoid open windows next to sides or back.ASSEMBLYThe fryer must be restrained to prevent tipping and the splashing of hot liquid. The means of restraint may be the manner of installation, such as connection to a battery of appliances, installing the fryer in an alcove, or by separate means such as adequate ties.FLUE CONNECTIONMake the flue connection as follows:☆ Locate the fryer under a hood with adequate connection to an exhaust duct. The hood must extend 6” (15 cm) beyond fryer on both sides.☆ Clearance above the fryer should be adequate for combustion by-products to be removed efficiently.☆ An 18” (46 cm) minimum clearance should be maintained between the flue ventand the filters of the hood venting system.☆ Never make flue connections directly to the fryer.☆ Do not obstruct the flow of the gases from the appliance. Proper air balance should be maintained in the room.GAS CONNECTIONAll gas supply connections and any pipe joint compound must be resistant to the action of propane gases.The gas inlet is located on the lower rear of the fryer. Codes require that a gas shutoff valve be installed in the gas line ahead of the fryer.The gas supply line must be at least the equivalent of ½” (12.7 mm) iron pipe for single units and 1-1/4” (31.75 mm) for batteries. If using the optional quick-disconnect flex hose, ¾” (19 mm) iron pipe for single units and 1-1/4” (31.75 cm) iron pipe for batteries.Make sure the pipes are clean and free of obstructions, dirt, and piping compound. A battery requires one or two connections of appropriate size for the gas requirement.Prior to lighting, check all joints in the gas supply line for leaks. Use soap and water solution. Do not use an open flame.After piping has been checked for leaks, fully purge gas pipes to remove air.GAS PRESSURES (ALL MODELS):The available gas pressure should be the same as that indicated on naming plate. If incoming pressure exceeds 5 kPa, an additional pressure regulator must be installed.TESTING THE GAS SUPPLY PIPING SYSTEM:When test pressures exceed 5 kPa, the fryer and its individual shutoff valve must be disconnected from the gas supply piping system.LEVELING THE FRYERCheck the level of the fryer by placing a level on top of the fryer after gas connections have been made. Ensure that the fryer is level front-to-back and side-to-side in the final installed position. If using casters, lock the wheels after unit is level.Air adjustmentUnscrew the locking screw of the burner air shutter and adjust the air shutter to desired height. In the above picture you can find the suggested height for different types of gases. The height is the distance between burner base and air shutter.OPERATIONOVER-TEMPERATURE SHUTDOWNIf the shortening becomes overheated, a high-temperature shutoff device will turn the gas valve off and extinguish the pilot.If the fryer shuts down due to overheating, DO NOT re-light the pilot until the shortening℃℉temperature is below 149 (300 )If an overheating situation persists, contact qualified technician for help.BEFORE FIRST USECleaningNew units are wiped down at the factory to remove any visible signs of dirt, oil, grease, etc. remaining from the manufacturing process.Before any food preparation, thoroughly wipe protective oil from all surface parts and the tank interior with hot soapy water to remove any film residue and dust or debris.Do not use chlorine or sulfate/sulfide cleaners.☆ Wash any accessories shipped with unit.☆ Rinse fryer and accessories thoroughly and drain the fryer. Š Wipe tank completely dry with a soft, clean cloth.FILLING TANK WITH SHORTENINGSolid shortening should NOT be used with this type of fryer. Melting solid shortening will damage the tank.☆Close the drain valve.☆Fill the fryer tank with liquid shortening.☆Shortening level should be between the min and max lines in the fryer tank. ☆Shortening will expand when heated. Do not ill the fryer tank past the☆MAX line.☆Add fresh shortening as needed to maintain oil level.LIGHTING THE PILOT1. Open the door.2.Turn the thermostat OFF (see figure above). The thermostat is located behind the door.3.Push the gas control valve knob and turn to “O” (see figure below, view A). Wait 5 minutes forunburned gas to vent.4.5.While still holding the knob in, light the pilot with a lit flame. Continue to depress the knobuntil pilot remains lit when knob is released. If the pilot does not remain lit, repeat step 3 through 5.6.Depress and turn gas control knob to “” (See figure below, view C).7.If gas supply is interrupted, repeat steps 2 through 6.TURNING ON THE FRYER1. Set the temperature knob to desired temperature.2. After the set temperature has been reached, the thermostat shuts off the gas flow to burners.3. The pilot remains lit. The burners will cycle on and off, maintaining the set temperature. TURNING OFF THE FRYER1. Turn the thermostat OFF.3. To shut off all gas to the system, including the pilot, turn the gas valve knob to “O”. EXTENDED SHUTDOWN1. Turn the thermostat knob to OFF.2. Push in the pilot knob and turn to “O”.3. Thoroughly drain the fryer. Refer to DRAINING THE FRYER.4. Clean the fryer according to CLEANING.5. Turn off the main gas shutoff valve.BASIC FRYING INSTRUCTIONSet the desired temperature and allow shortening to heat up to that temperature.Fry items that are about the same size together to ensure equal doneness.Drain or wipe dry raw or wet foods to minimize splatter when lowering into hot shortening. Add fresh shortening as needed.Fry Basket GuidelinesDo not overfill baskets. Carefully lower basket into oil.When frying doughnuts and fritters, turn product only once during frying.When cooking French fries or onion rings, shake the basket several times in a way that does not splatter the shortening.Batter-covered foods should be dropped carefully, one by one, into shortening or basket. If you use the basket, first dip the basket into the shortening to reduce batter-build up on basket surfaces. When frying is completed, remove basket or product. Hang basket on rear hanger.EXTENDING SHORTENING LIFEShortening life can be extended by the following guidelines:☆ Do not salt foods over the fryer.☆ Use good-quality shortening.☆ Filter shortening daily (at a minimum).☆ Replace shortening if it becomes poorly flavored.☆ Keep equipment and surrounding clean.☆ Set thermostat correctly.☆ Remove excess moisture and particles from food products before placing on fryer. DRAINING THE TANK1. Turn the thermostat to OFF.3. Direct the drain spout into the container that you want to drain the shortening into.4. Open the drain valve. The oil will drain into the container. When the container is full or the fryer tank is empty, close the drain valve. Repeat this step until the fryer is empty.5. If desired, perform the weekly clean-out as described under CLEANING.6. Once tank is completely empty, add new shortening and set thermostat to desired temperature. DAILY FILTERING☆ Filter shortening at least once a day. Refer to the instructions provided with your filtering equipment.☆ A cold fryer will not drain properly. Always filter shortening between 250F and 350F. The shortening in the cold zone area will remain hard if the heat is only on for a few minutes. If necessary, use the clean-out rod to carefully stir the hard shortening to an area above the cold zone where it will melt. Use the tank brush to help clear sides and tubes of debris.CLEANINGDailyClean your fryer regularly with the tank brush along with a damp cloth, and polish with a soft dry cloth. If regular cleaning is neglected, grease will be burned on and discolorations may form. Fingerprints are sometimes a problem on highly polished surfaces of stainless steel. They can be minimized by applying a cleaner that will leave a thin oily or waxy film.☆ Clean all exterior surfaces of your fryer at least once daily.☆ Use a damp cloth with warm water and a mild soap or detergent.Do not use chlorine or sulfate/sulfide cleaners.☆ Rinse thoroughly, and then polish with a soft dry cloth.☆ Keep the fryer exterior clean and free of accumulated grease to prevent stubborn stains from forming. If regular cleaning is neglected, grease will be burned on and discolorations may form. ☆ Remove discolorations by washing with any detergent or soap and water.☆ Use a self-soaping, non-metallic scouring pad for particularly stubborn discolorations.☆ Always rub with the grain of the stainless steel. Š Do not use a metallic scoring pad or harsh cleaners.BOIL OUT PROCEDUREWeekly or as required:1.Drain the tank as described under DRAINING THE TANK.2.Once the shortening has been drained, flush out scraps and sediment with a small amount ofwarm shortening, using tank brush. Allow the tank to drain thoroughly.3.Close the drain valve and fill tank with non-corrosive, grease-dissolving commercial cleaner.Follow the manufacture’s instructions.Do not use chlorine or sulfate/sulfide cleaners.4.Add commercial boil-out solution. Solution level must be between the MIN and MAX levelson the fryer tank.5.Set thermostat to the temperature recommended for the solution being used. Allow solutionto simmer for about 15 to 20 minutes.6.Drain the cleaning solution from the tank.7.Close the drain valve and refill the tank with water. Add 1 cup (1/4 L) of vinegar to neutralizealkaline left by the cleaner. Solution level must be between the MIN and MAX level on the fryer tank.8.Bring the solution to a simmer only, turn the thermostat off. Allow to stand for a fewminutes.9.Drain the tank according to DRAINING THE TANK. Rinse thoroughly with clear, hotwater. All traces of cleaner must be removed. Dry the tank thoroughly.10.Close the drain valve and add shortening. Follow the FILLING TANK WITHSHORTENING procedure in this manual. The fryer is now ready for use.

NG fuel is supplied by the pre-mixed closed-loop control mode outside the cylinder. ECM collects the fundamental signals and correction signals to accurately determine the required volume of gas supply, and performs the closed-loop control for the air-fuel ratio through the feedback of universal exhaust gas oxygen sensor in order to improve the power, economy, emission, etc. High-pressure regulatorHigh-pressure regulator is a secondary pressure relief devicewith the adjustment range of 25 MPa-0.8 MPa. High-pressure regulator has an onboard fuel temperaturesensor. When the fuel temperature drops to less than the allowable limit, ECM will issue commands to limit the engine power in order to protect the downstream fuel system parts. High-pressure regulator requires engine coolant for heating,so the installation location shall not be higher than the top of engine radiator, otherwise it will make the heating water unable to flow through the regulator, resulting in the regulator cracking due to icing. Heat exchangerHeat exchanger is a device for gas heating.based on the actual situation of vehicle.Low-pressure solenoid valveLow-pressure solenoid valve core, with its core driven by the coil, is controlled by ECM to open/close and cut off or restore the fuel supply timely. Electromechanical fuel cutoff solenoid valve is used to block EPR (electronic pressure regulator) and all downstream parts with upstream fuel when the engine is offFig. 2-5-2 Heat ExchangerFuel inletFuel outletCirculating water outletCirculating water inletFig. 2-5-3 Low-pressure Solenoid ValveDouble-stage pressure regulator (DSR)Currently, double-stage pressure regulator is only used on 12 L NGengine, and each engine has 2 such regulators. The fuel intakepressure is not greater than 1.725 MPa.Fig. 2-5-4-1 Double-stage Pressure Regulator (DSR)Fig. 2-5-4-2Electric Pressure Regulator (EPR (10 L)Fig. 2-5-4-3D28 EPR (12 L) Fig. 2-5-7ECI engine management system adopts the electronic pressure regulator (EPR, D28 EPR as shown in Fig.4-13) to control the delivery of fuel, so as to accurately calculate the volume of fuel for optimal combustion, fuel saving and transient response.EPR fuel intake pressure range is from 689 to 1,378 kPa; D28 EPR fuel intake pressure ranges from 3.5 to 6.9 kPa. MixerMixer is a variable venturi tube and used to adjust thevolume ratio of fuel and air entering the engine. Mixer introduces the fuel into the engine by mixing the airand fuel, and 2 internal valves in reverse positions are used to control the fuel-air ratio in the flow range. Mixer model: 10 L 200DM 12 L E480Electronic throttle valveECM controls the volume of gas mixture entering the cylinder by controlling the opening of butterfly valve of electronic throttle valve, so as to manage the engine speed and load. Driver sends the power demand to the ECM through the accelerator pedal. ECM receives the signals from the accelerator pedal, and then controls the opening of electronic throttle valve according tothe operating conditions ofengine.2.6 Electronic Control Ignition SystemIn the electronic control ignition system of engine, ECM, sensor and actuator are connected as shown in Fig. 4-16.Fig. 2-5-5 MixerFig. 2-5-6 electronic throttlevalveFig. 2-6-1 Connection of Controller, Sensor and ActuatorThis system implements the single-cylinder high-energy sequential ignition. The igniter integrates the ignition coil and high-energy circuit module, and a cylinder with an igniter is connected on the spark plugthrough the electrode with lengthened hose to ensure the good contact of igniter electrode lead and spark plug, which can improve the operational reliability of spark plug.Electronic control moduleThe management core of electronic control NG engine monitors the operating conditions of engine through a variety of sensors, and controls the operations of each actuator based on theoperatingCrankshaft positionsensor Camshaft positionsensor Engine coolantsensor Turbocharger/temperature sensor Environmentalsensor Pressure sensorUniversal exhaust gas oxygen sensor Knock sensorOil pressure switchFuel tanktemperature sensor Fuel tank pressuresensor Electronic accelerator pedalExhaust door controlvalveInputOutputCommunicationIgnition coilHigh-power electronic pressure regulator (for10 L engine)Electronic throttleFuel cut-off valveCheck the engineMalfunction indicator lampStarter interlockingrelayInstrument panelElectronic pressure regulator (for 10 L engine)conditions and MAP .

Fig. 2-6-2 Electronic Control Module (ECM)Exhaust bypass control valveFig. 2-6-3 Schematic Diagram of Anti-Surge Valve and InstallationIt controls the outlet pressure of exhaust bypass control valve by controlling the duty cycle, so as to control the opening of exhaust relieve valve. Control valve is equivalent to a three-way electromechanical valve with the pulse width adjusted by ECM in order to provide the precise pressure rise control as shown in Fig. 2-6-3. The preferred gas source is the chassis brake air system. Gas source filtering requirements: a filter shall be installed in the device upstream with the filtering accuracy of 30 µm (efficiency up to 95%) or better. The supply pressure shall be controlled within 138 - 172 kPa. Anti-surge valveFig. 2-6-4 Schematic Diagram of Anti-surge Valve and InstallationThe anti-surge valve (Fig. 2-6-4) is used as a protection device of turbocharged engine. Under normal circumstances, anti-surge valve is in a closed status. In case of the sudden deceleration of engine, the low pressure behind the throttle is transferred to the pressure feedback connector of anti-surge valve through the anti-surge valve hose to open the unidirectional cut-off diaphragm of anti-surge valve, and then the high pressure in the downstream of supercharger may flow back to the upstream of supercharger. Front and rear pressures of supercharger compressor may be balanced to avoid the surge of supercharger and prevent the acceleration wear and fatigue on the supercharger parts to protect the supercharger.

康诺流体 HPNGV2 系列压缩天然气车用调压器使用说明书和维护手册
Enidine / Conoflow105 Commerce Way Westminster, SC 29693Tel: (864) 647-9521 Fax: (864) 647-9574INSTRUCTION AND MAINTENANCE MANUALHPNGV2 Series Compressed Natural GasVehicle RegulatorWARNING: These instructions must be read carefully prior to installation and system startup.INTRODUCTION: The HPNGV Series regulator is a self contained, pressure reducing regulator designed and qualified for 3000 and 3600 psig CNG vehicular fuel systems. This regulator is factory calibrated and is not field adjustable. Various configurations of this regulator are available, based on the application needs. Consult the factory for part numbers, service kits, or configuration assistance.SYSTEM REQUIREMENTS : High pressure CNGfiltration (1 micron rating) is required to keep particulates in the gas stream from damaging the regulator and downstream components. The filter must be located upstream of the pressure regulator. Clean, burr free fittings and lines must be used to prevent particulate damage to the regulator.CONNECTIONS : The HPNGV Series regulator is connected to the fuel system by inlet and outlet ports. These ports use CNG compliant SAE J1926 o-ring boss connections for 3/8” size tubing at the inlet connection (9/16-18 thread) and 1/2” size tubing at the outlet connection (3/4-16 thread). These connections are labeled “INLET” and “OUTLET”. The inlet and outlet lines must be sized for sufficient flow, and the outlet fitting must provide a 3/8” minimum bore for gas flow.A coolant circulation bowl is provided which permits engine heat to warm the regulator and prevent internal icing of the regulator valve. An optional coolantcirculation bowl is available with a thermostat. Both coolant bowls are labeled for coolant inlet and outlet, adjacent to the connections. Standard coolant lineconnections are for 3/8” reinforced rubber hose, which is secured with hose clamps.An optional SAE-3 transducer port is available to allow a high pressure transducer to be directly installed in the regulator to measure inlet pressure.Optional pressure bias controls (manifold pressure reference) are available.A pressure relief device (PRD) is provided. Standard (light duty) configurations discharge directly to atmosphere, while capture pipes are available for enclosed spaces or heavy duty applications.CAUTION: The regulator’s PRD is a control and nota system safety device. It may not protect theregulator or fuel system under all possible / potential failure modes. A downstream safety valve or other failsafe strategy must be used to fully protect the fuel system and vehicle. The PRD port must not be blocked by any obstruction.MOUNTING : Two (2) M8 X 1.25 threaded holes areprovided in the regulator to enable sturdy mounting. The regulator may be oriented in any direction; however Conoflow recommends that the gas ports arehorizontally oriented to minimize exposure of the gas lines, and prevent collection of oil and moisture in the downstream line. The regulator must be rigidly mounted on the vehicle, and protected from impact of road debris.WARNING : Do not mount the regulator by gas or coolant connections only. This regulator must be securely mounted by M8 x 1.25 bolts.Please refer to the interface drawings for mounting dimensions, connection identification and connection details.SPECIFICATIONS:Maximum Operating Inlet Pressure:3600 psig (248 bar)Outlet Pressure: Factory preset – see regulator labelWARNINGConoflow’s products are designed andmanufactured using materials and workmanship required to meet applicable standards. The use of these products should be confined to services specified and/or recommended in the Conoflow catalogs, instructions, or by Conoflow application engineers.To avoid personal injury or equipment damage resulting from misuse or misapplication of a product, it is necessary to select the proper materials of construction and pressure-temperature ratings which are consistent with performance requirements.Outlet Pressure Variation in Service: -10 to +18 psi from labeled setting throughout the range of operating inlet pressure, temperature and gas flow. See flow performance graph to see effect of changes to inlet pressure and gas flow.Temperature Range: -40° F to 250° F(-40 °C to 120 °C) Connection Torques: Inlet (SAE-6): 27 ft-lbOutlet (SAE-8): 42 ft-lbTransducer (SAE-3): 8 ft-lbMounting Bolts: 15 ft-lbFlow Capacity: To 175 lb/hr of CNG.

There are significant potential hazards associated with CNG which the user and / or installer must be aware of when using this product.CAUTION: Install the regulator in accordance with NFPA 52, CAN/CGA-B149.4 and other codes and standards applicable to the jurisdiction of installation and service.WARNING: CNG can cause damage and / or injury due to very high pressure, flammability, and extreme cold during expansion. Suitable safeguards must be employed during installation, commissioning and service to prevent harm to personnel and property.PRINCIPLE OF OPERATIONThe HPNGV series is a mechanical pressure regulator. The main valve, within the regulator, is coupled to a diaphragm assembly. A spring preload against the diaphragm assembly pushes the main valve open. As gas flows through the regulator, downstream pressure will increase and push the diaphragm assembly against the spring load, closing the main valve. The diaphragm and valve are dynamic, and will seek equilibrium so the inlet pressure is reduced and regulated throughout the useful range of gas flow.When the engine is shut off, gas flow through the regulator ceases. The regulator’s main valve is pulled closed by the diaphragm assembly and downstream pressure will be trapped in the low pressure side of the fuel system.An engine coolant circulation bowl is fitted over the end of the regulator to provide engine heat to the regulator valve and the gas. This heat prevents ice buildup in the regulator, which could reduce performance and regulator life.INSTALLATION GUIDELINES1. Plan the installation for the best combination ofaccessibility, protection from engine exhaustheat, mechanical vibration or impact, andsuitable mounting orientation.SEE SYSTEM IMPERATIVES ON PAGES 3 and 42. A suitable lubricant (oil, synthetic grease, etc)should be applied to the o-ring of the fitting, priorto installation, to help the o-ring seat and seal.Do not use silicon grease – silicon may poisonthe oxygen sensor in some vehicles. Install thefitting in the applicable gas port.3. If the regulator is equipped with an optional PRDcapture pipe, connect the system fitting to thecapture pipe.NOTE: If the optional ¼” NPT PRD CapturePipe is used, it must be wrench supportedduring connection.4. Attach regulator securely to vehicle, using twoM8 x 1.25 mounting bolts (not included).5. Connect the inlet, outlet, and coolantconnections. Assure any entrapped air inregulator is fully purged from coolant bowl. Ifapplicable, connect the PRD and transducer.6. Pressurize the system and perform a leak test ofgas connections with liquid leak detectionsolution or soapy water.SYSTEM IMPERATIVESImperatives are those conditions, when violated, can cause regulator or system failure and an increased risk of gas release. The following imperatives are listed with potential risks to assist the fuel system integrator with system design failure modes and effects analysis.1. Upstream Coalescing FilterAlthough the regulator is equipped with an internal filter, a suitable coalescing filter must be installed immediately upstream of the regulator. This filter should be sized for suitable flow and condensate capacity. The purpose of this filter is to prevent excessive moisture and compressor oil or particulate contaminants from entering the regulator and flowing downstream to the fuel management system.A one (1) micron filter will sufficiently protect the regulator from particulate contamination damage.This filter must be located as close to the regulator as possible to prevent any particulate in the connection between the filter and regulator from accelerating upon system pressurization, and piercing the regulator’s internal filter.2. Upstream Lockoff (solenoid) ValveA normally closed solenoid valve must be installed upstream of the regulator. This is a safety requirement to prevent gas from freely flowing during vehicle shutdown. Although the regulator is capable of bubble tight shutoff, the upstream lockoff valve is the correct safety device for this function.3. SealantsSealants are not required for the SAE o-ring boss connections. The use of sealants as a fitting leakage preventive measure can contaminate the internal passages and valve in the regulator and cause a malfunction. Sealant use in these connections will void the factory warranty.4. Inlet / Outlet LinesTo prevent excessive pressure drop at flow, the inlet and outlet fuel lines should be of suitable size. The regulator has been designed for SAE o-ring boss fittings which correspond to 3/8 inch OD tubing (SAE-6) for the inlet, and 1/2 inch OD tubing (SAE-8) for the outlet. These are the recommended line sizes. Excessively large line or fitting diameters may induce instability of the delivery pressure. The minimum bore of the fittings must be a minimum of 0.27 inch (6.8 mm) for the SAE-6 inlet fitting and 0.37 inch (9.4 mm) for the SAE-8 outlet fitting. Fittings may be of type SAE J1926/2 or SAE J1926/3.Tubing must be clean and free of burrs, which could contaminate the regulator or system. The outlet line should not be run upward from the regulator outlet port, due to the potential for excessive oil and condensate collection. A level or downward run is preferred to prevent collection.5. Downstream Relief ValveAlthough the regulator is equipped with a pressure relief device (PRD), a high flow relief valve or other protective strategy must be installed between the regulator outlet and the remainder of the fuel system. The regulator PRD is not a high flow device and may not protect the regulator or fuel system in case of sudden failure.6. Engine CoolantThe expansion of high pressure gas to low pressure creates a significant temperature drop. To prevent moisture from freezing inside the regulator and creating a blockage, heated engine coolant must be circulated within the regulator. The regulator is equipped with a coolant bowl for this purpose.Engine coolant must be maintained for at least –40 degree antifreeze protection. If the coolant were to freeze in the regulator, for any reason, the coolant containment integrity may be compromised.Suggested minimum flow: Engine idle 1-2 lpm, Moderate power 3-6 lpm, depending on engine size.7. Excessive TemperatureThe regulator is designed for safe and reliable operation within a temperature range of –40 to 250 °F. Temperatures beyond 275 °F can cause permanent damage to internal seals and must be avoided. If the regulator is located in an area with the potential for high temperature (such as radiated energy from exhaust system components, etc), suitable heat shields must be employed.8. Fitting TorqueThe correct assembly torque for the inlet (SAE-6) fitting is 27 ft-lb.The correct assembly torque for the outlet (SAE-8) fitting is 42 ft-lb.The correct assembly torque for the optional transducer port is 8 ft-lb.Inadequate torque could allow the fitting to loosen in service and leak. Excessive torque could weaken or shear the threads in the inlet and / or outlet port of the regulator.The inlet and outlet fitting is sealed with an o-ring.9. Submergence in waterExcept for bonnet bias models, the regulator uses an atmospheric reference hole in the bonnet to sense ambient pressure. This hole is “filled” with a porous hydrophobic plastic plug to prevent water intrusion from splashing, wash down, etc. This plug may not prevent water intrusion if the regulator were to be submerged in water. For this reason, the regulator should not be mounted low in a vehicle which would have to cross flooded roads, etc.10. Chemicals in FuelAny cleaners or abnormal additives, drying agents, etc in the fuel could cause damage to the regulator’s internal seals. The regulator is tolerant to substances that occur in compressed natural gas, including compressor oils, however ITT Conoflow should be contacted regarding other materials.11. Rapid or Frequent Fuel System DecompressionCNG Fuel systems should not be rapidly or frequently decompressed of gas. Doing so will cause high pressure gas absorbed in non metallic materials to attempt to escape those materials, increasing the speed of component degradation.12. Salt and/or Dirt BuildupExcessive road salt and/or road dirt buildup will accelerate moisture attack and subsequent corrosion of the regulator at the solenoid and/or gas connections. Accelerated corrosion leads to premature external gas leakage failure.The regulator must be installed in a manner which provides reasonable protection from road salt and debris accumulation, to reduce the risks of accelerated corrosion.13. Pressure AdjustmentThis pressure regulator is factory calibrated and tested. Removing the tamper evident cover from the adjustment will void the warranty.14. Fuel System ValidationThis fuel pressure regulator will dynamically respond to the CNG fuel system. In new applications it is the responsibility of the customer to validate the performance of the fuel system with this regulator. ITT cannot be responsible for the suitability of this fuel pressure regulator in every application.15. Fuel Type / Quality This fuel pressure regulator is designed and qualified for CNG fuel. RNG (Renewable Natural Gas) is acceptable, provided it meets the quality guidelines of the American Biogas Council (ABC) for CNG fuel. This fuel pressure regulator is not for use with raw biogas.As part of your fuel system and vehicle protection review, ITT recommends the incorporation of a system warning label that clearly advises maintenance technicians to 1) NOT DISABLE any automatic upstream isolation valves and to 2) CLOSE upstream isolation valves, whenever feasible during servicing.WARNING: Bleed system pressure prior to servicing or removal of the pressure regulator from the fuel system.CAUTION: Stored spring compression within the regulator can be unexpectedly released if the regulator is disassembled incorrectlyTROUBLESHOOTING:1. The regulator “pops” when I turn on ignition keyand activate tank solenoid valve(s).This is caused by downstream leakage, orintentional fuel system decompression. If thedownstream pressure bleeds down, the inrush ofhigh pressure CNG can cause the regulatoroutlet pressure to overshoot the PRD openingpressure and discharge excessive pressure fromthe line. Correct / repair any downstreamleakage to prevent system depressurizationwhen the vehicle is not operating.2. After driving the vehicle, I see frost on theexterior of the regulator and outlet fuel line.This is quite common for driving cycles wherethere is a significant amount of gas flow.Although the regulator is heated with enginecoolant, this heat is used to protect the valve,and is not sufficient to heat the fuel completely.As the fuel flows to the engine, it will pick upheat from the fuel line. Some heavy dutyapplications may require a downstream heatexchanger.3. When leak testing the system, our gas detectorshows leakage from the white plug on theregulator.A very slight amount of gas permeates from theregulator, and this is normal. A gas detector can show leakage “false alarms”, as this instrumentis very sensitive. Conoflow recommends usingcommercially available leak detection solution,or soapy water, to leak test the system.4. Loud noises are coming from the regulator.Noisy operation can be caused by a number ofsystem related issues. If incorrectfittings or line sizes are used (small bore fittings, tubing too small), the regulator may be starvedfor pressure and overshoot the steadyequilibrium it is trying to achieve. This will cause internal oscillation which can create noisesranging from a buzzing sound to a rapid internal knocking sound.In rare instances, the regulator’s resonantfrequency (typically around 380 Hz) will matchthe fuel system’s resonant frequency. Simplychanging the length of the outlet line will usuallysolve this issue.MAINTENANCEProperly designed and maintained fuel systems will increase the reliability and life of this pressure regulator.1. Follow vehicle guidelines for fuel system filter maintenance and engine coolant maintenance.2. Keep the exterior of the regulator clean to reduce buildup. Dirt or salt buildup can attract moisture and accelerate corrosion. Protective sprays may be used in areas where dissimilar metals (gas connections, etc) meet.3. Schedule leak testing to verify regulator gas containment. Leakage is the result of wear and aging; it is the inevitable failure mode of the pressure regulator.Regulator Model Breakdown (CED Code)1 through 6 HPNGV2 Regulator Base Model7 S Standard BonnetC 3/16” Straight Hose Barb Connection on BonnetE 1/4” Tube Elbow (for Poly Tubing) Connection on Bonnet8 X No Sensor Port3 SAE-3 Sensor Port4 SAE-4 Sensor PortW Sensor (Installed) 0.25 to 4.75 Volt OutputY Sensor (Installed) 0.50 to 4.50 Volt Output9 T Integral Coolant Hose ConnectionsH Brass Coolant Hose Connections10 A 200 psi (+/- 40) PRD SettingB 270 psi (+/- 60) PRD SettingC 350 psi (+/- 60) PRD Setting11 X PRD Discharges to atmosphereP 1/4” Male NPT PRD Capture PipeT 1/2” Tube Stub PRD Capture Pipe12 through 14 XXX Output Pressure Setting (PSI)CAUTION: Regulator is factory preset.

Gas GuideDealing with Gas Problems:Boiler/Heating InsuranceIf you would like the security of having your boiler and central heating maintained regularly and the peace of mind that someone will come out and carry out repairs if it breaks down then you may like to consider insurance.Your own gas supplier may offer this but you are able to take out cover from another supplier if it suits you better. Some covers can include not just your heating but a complete package which covers your plumbing and electrics too.If your system is old or you are not confident that you would be able to resolve a possible problem yourself, it may be worth considering this option. Common problems you may have with your central heating system and howyou might fix them.Radiators:Before winter sets in, you should ensure your heating system is working correctly. Ideally you should have had your heating on at regular intervals during the summer so that system continues to work efficiently.To test your radiators are working correctly, switch on the heating and make sure that the heat is spread evenly throughout each radiator. Ensure that the valves are fully turned on, on each radiator.The radiator is making a noise:If your radiators or heating system seem to be making a noise then it may mean that there is air trapped somewhere. You should check the water tank in your loft, if it is easily accessible; to make sure that there is enough water in it and that it is filling up correctly. If there is water in the tank or you do not have a tank, but a combination boiler then the problem is probably in the radiators, which can be fixed by bleeding them.The Radiator is warm at the bottom but cold at the top:If the radiators are warm at the bottom but cold at the top, then this may also mean that there is air trapped in the top section so you will need to bleed them.It is simple to bleed your radiators; you simply need to let the air out of the radiator by turning the radiator key. As you turn the key, air will be released, the water will push its way to the top, removing all the excess air and once a small amount of water comes out of the valve you should turn the key back. You should have a cloth ready in case the water is hot and to avoid any spillage.The Radiator is cold at the bottom but warm at the top:If the radiator is cold at the bottom and warm at the top and this problem persists, then there may be some sludge at the bottom of the radiator and it may need flushing out. For this, the radiator will need to be taken off the wall, flushed out with water and refitted. This can be done by yourself if you follow the correct instructions and have a basic understanding of how your heating system works but if you have not done it before or are unsure of the procedure, then you will need to call a plumber or engineer out.If several of your radiators have this problem and it is not solved by flushing the radiator out then the problem may be more serious. This could be caused by a fault with the circulating pump, blocked pipes or radiators or a badly designed system. You will need to call a professional out to look at this problem further as it may require the whole system to be flushed through or repairs to be carried out.The radiator is working correctly but not at the desired temperature.If your radiators are working correctly but are not hot enough or are too hot then you can alter the temperature by either adjusting the controls on your boiler or for more modern radiators with their own temperature controls, simply turn up or down accordingly.InsulationInsulating your house properly can save you money on your heating bills and insulating your heating system properly can save you the inconvenience and money of it breaking down.There are a few things you can do yourself to ensure your system runs well through the winter. Insulating your water tank and your pipes can prevent them from freezing up. Your water tank - usually up in your loft should havean insulating jacket on and water pipes, especially in places more exposed to the cold should have pipe insulation on them. Preventing your pipes and water tank from freezing could save you on expensive repair bills.For extra protection against the cold you can also get a frost thermostat fitted which will automatically turn your boiler on if the temperature drops below a certain level. This can give you the peace of mind if you are away for any period during the winter as a safeguard against the system freezing. It is not recommended to switch your heating off completely if you are away during the winter as if you do not have a frost thermostat you could come back to frozen pipes.Loss of pressure in your system:For a system to work properly the water pressure should remain constant. Modern combination boilers are pressurised systems and water will enter the system from the mains cold water supply through a manual filling device, known as a ‘filling loop’. Adding water via the filling loop to the system after a drop of pressure will help bring your system to the correct pressure again.There are several factors which may contribute to a loss of pressure in your heating system. It could be as a result of a water leak or air removed from the system when the radiators have been bled or removed and replaced. You check the pressure after bleeding or removing the radiators and if you notice a drop of pressure then the system will need to be topped up with water.Water leaks will also cause a drop of pressure , leaks can be very small and go unnoticed as pressure can decrease over a couple of months. Small leaks are quite hard to detect as the water evaporates quickly. If you think there is a leak, you should check the system thoroughly when it is cold especially around the radiator and boiler valves. Larger leaks will mean that you will need to regularly refill the system; these should be repaired as soon as possible.You can check the pressure of the system by using the pressure gauge which you should find on your boiler. You should check this gauge regularly to make sure it is at the correct pressure. It should be between the 1 and 1.5 bar. It should not drop below 0.5 or rise above 2.5.If the pressure is too low then you need to re-pressurise the system by topping it up via the filling loop. This is usually a small tap connected to the system via a metal hose. If the hose is not connected to the system you will need to remove the cap,the end and attach and tighten it. Once attached, you need to turn the tap, whilst watching the gauge and let enough water in to raise the gauge to the correct level (1-1.5bar).The filling loop will always be located near to the boiler but if you can't see it straight away it may be in a cupboard or perhaps behind a boarded section. If you cannot find the filling loop, consult your manufacturer's booklet or ask your service engineer.Gas emergenciesGas leak:Gas is usually a safe and easy way to heat your house but it can also be potentially dangerous if a leak occurs or an appliance is faulty.If you smell gas or think that you may have a gas leak somewhere then you should call National Grid Gas Emergencies on 0800 111 999 straight away. Open your windows and doors to let air in, make sure all gas appliances are turned off and turn the gas off at the mains if possible. Do not turn lights on or off and avoid using other electrical switches and appliances as this could trigger an explosion. Do not smoke, light a match or any other naked flame.Do not try and investigate the problem or attempt to fix a leak or a faulty appliance.Loss of gas supplyAlthough very rarely, there may be times when National Grid may have to interrupt the supply of gas to your home.They promise to give customers sufficient notice of any interruption, keep interruption to a minimum and make interruption requests on an equitable basis.Reasons for interruptions can include network capacity constraints, high system demands, testing and other emergency situations. The National Grid has to keep certain standards of performance and these state that they must notify customers of planned interruptions an in the result of an unplannedinterruption, such as an emergency, they must restore the supply as soon as is possible.Compensation may be available if they do not meet these standards and payments will be made to you either via your gas suppliers or from National Grid directly.Carbon Monoxide poisoningCarbon monoxide poisoning causes a number of accidental deaths every year when gad appliances are installed incorrectly, badly maintained or poorly ventilated. It is so deadly as you cannot see, smell it or taste it. Being exposed to carbon monoxide can cause brain damage and even death.All appliances should be safety checked and maintained and it is especially important if you live in rented accommodation that the landlord checks and maintains any gas appliances. This is a legal requirement.Although carbon monoxide is invisible and difficult to detect, there are ways that you can see whether an appliance (fires, heaters, central heating boilers, water heaters or cookers) may be dangerous. These include:•The pilot light continually blowing out•An orange and yellow flame rather than a blue one• A black, brown or scorched area on an appliance• A musty smell or signs of soot•More condensation than normal on windowsTo keep your house safe and check for the presence of carbon monoxide you can use a carbon monoxide detector. These detectors sense if there is any carbon monoxide in the air and change colour or set an alarm off to warn you. You can buy detectors in hardware or DIY stores and you should make sure that it meets the correct standard before purchasing it. The label should display BS 7860 in Britain, showing it is officially approved by the CO Alarm Standards. You should test your detector every month and replace batteries when necessary. Detectors don't last forever so you replace them as recommended by the manufacturer.Don't ever ignore the detector and if you suspect carbon monoxide is present in your home then you should evacuate everyone immediately.Symptoms of carbon monoxide poisoning can include: headaches, fatigue, dizziness, nausea, diarrhoea, stomach pains, chest pains and erratic behaviour. A faulty gas appliance can cause these symptoms and you should be wary if the symptoms worsen when a gas appliance is in use and if the symptoms lessen when away from the house but then return again when you are back in the property.Gas safety tipsGas, when not used carefully, is a potentially dangerous source of energy. Following are a number of tips about making sure the gas supply in your home is safe:•The best way to be sure about your gas appliances is to have them checked regularly by your gas supplier, or by a Corgi RegisteredInstaller. Corgi are the national watchdog for gas safety.• NEVER tamper with gas appliances yourself.•If you are in rented accommodation, it is your landlord’s responsibility to ensure that all appliances are maintained properly. If you have anyconcerns about appliances in rented accommodation, talk to yourlandlord.•Poorly maintained gas appliances ( in particular gas fires) can emit Carbon monoxide, an odourless, colourless and potentially fatal gas.Carbon Monoxide detectors can be bought relatively cheaply from most good electrical and home stores to alert you if carbon monoxide ispresent in your home.•If your carbon monoxide detector shows a presence of carbon monoxide, switch off your gas supply and call National Grid’semergency number IMMEDIATELY on 0800 111 999•If you smell gas, or think you have a gas leak in your home, turn off your gas supply, do not switch any electrical appliances on or off, orbring naked flames into your home, and call National Grid's emergency number IMMEDIATELY on 0800 111 999.Source: 。

GAS PIPINGA.CONNECT GAS SERvICE from Meter to gas controlassembly in accordance with Local Piping Codes andrequirements of Gas Company. They may requirepiping of larger size than Control AssemblyConnection, especially if run from meter is long orincludes several elbows. See Figure 1 for size of GasConnection to gas control assembly.This piping is to be supplied by the installer and mustinclude a trap, a ground joint union and a manualshutoff valve upstream of the gas control assemblyoutside of the jacket when codes require, see Figure 3.A pipe thread compound resistant to the action ofliquefied petroleum gases should be applied to allthreaded joints in the gas piping. Pressure testing of the Gas Supply Piping Boiler and its connections isrequired before placing the boiler in operation.The boiler and shutoff valve must be disconnected from the gas supply piping system during any pressuretesting at pressures greater than ½ psig (3.5kPa).The boiler must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at pressures equal to or less than ½ psig (3.5kPa).RECOMMENDED SIZING OF GAS SUPPLY PIPING TO BOILER FOR NATURAL GAS - shall be such as to provide the required supply of gas without undue loss of pressure between meter and the boiler. Gas supply piping should be sized in accordance with the Tables 1, 2 and 3. The following shall be taken into account:1. Allowable loss of pressure to assure a burnermanifold pressure of 3½" (8.9cm) water for natural gas.2. Supply of gas to be provided in cubic feet.3. Length of piping and number of fittings.4.

Install Temperature and Pressure gauge externally in boiler supply piping. All required components are included at factory supplied Miscellaneous Parts Bag (P/N 103669-01). See Figure 4 ‘Near Boiler Piping’.5. Install circulator with flanges, gaskets and bolts and circulator harness provided.6. F or recommended water piping, see Figures 5 and 6. Also, consult Residential hydronic heating Installation and Design I=B=R Guide.7. If this boiler is used in connection with refrigeration systems, the boiler must be installed so that the chilled medium is piped in parallel with the heating boiler using appropriate valves to prevent the chilled medium from entering the boiler, see Figure 7. Also consult Residential hydronic heating Installation and Design I=B=R Guide.If this Boiler is connected to heating coils located in air handling units where they may be exposed to refrigerated air, the boiler piping must be equipped with flow control valves to prevent gravitycirculation of boiler water during the operation of the cooling system.8. Use a boiler bypass if the boiler is to be operated in a system which has a large volume or excessive radiation where low boiler water temperatures may be encountered (i.e. converted gravity circulation system, etc.).Install a pipe tee at the boiler return along with a second tee in the supply piping as shown in Figures 5 and 6. The bypass should be the same size as the supply and return lines with valves located in theIV. BOILER WATER PIPINGFigure 4: Near Boiler Pipingbypass and supply outlet as illustrated in Figures 5 and 6 in order to regulate water flow to maintain higher boiler water temperatures.Set the boiler supply valve to fully open position, and the boiler bypass valve to half throttle. Operate the boiler and adjust the bypass valve to achieve 180°F to 200°F supply water temperature by closing the bypass valve to decrease supply temperature or opening the bypass valve to increase watertemperature. If the bypass valve is fully opened and the boiler water temperature is still below 180°F, slowly begin closing the boiler supply valve to achieve 180°F to 200°F supply water temperature. Caution: Never fully close the boiler supply valve.10. If it is required to perform a long term pressure testof the hydronic system, the boiler should first be isolated to avoid a pressure loss due to the escape of air trapped in the boiler. To perform a long term pressure test including theboiler, ALL trapped air must first be removed from the boiler. A loss of pressure during such a test, with no visiblewater leakage, is an indication that the boiler contained trapped air.11. OxYGEN CORROSION: Oxygen contamination of the boiler water will causecorrosion of the iron and steel boiler components, which can lead to failure. As such, any system must be designed to prevent oxygen absorption in the first place or prevent it from reaching the boiler.Problems caused by oxygen contamination of boiler water are not covered by U.S. Boiler Company's standard warranty.10I V .

BOILER WATER PIPING (continued)There are many possible causes of oxygen contamination such as:a. Addition of excessive make-up water as a result of system leaks.b. Absorption through open tanks and fittings.c. Oxygen permeable materials in the distribution system.In order to insure long product life, oxygen sources should be eliminated. This can beaccomplished by taking the following measures:a. Repairing system leaks to eliminate the need for addition of make-up water.b. Eliminating open tanks from the system.c. Eliminating and/or repairing fittings which allow oxygen absorption.d. Use of non-permeable materials in the distribution system.e. Isolating the boiler from the system water by installing a heat exchanger.B.OPTIONAL PROBE LWCO INSTALLATION1. A low water cutoff is required to protect a gas-fired hot water boiler when any connected heat distributor (radiation) is installed below the top of the hot water boiler (i.e. baseboard on the same floor level as the boiler). In addition, some jurisdictions require the use of a LWCO with a hot water boiler as a redundant safety control.It is recommended that the LWCO control is installed above the boiler to provide the highest level of protection. however, where the LWCO control is approved by the LWCO controlmanufacturer for installation in a high boiler tapping of a water boiler, the use of the listed LWCO control is permitted when it is installed according to the LWCO manufacturer's instructions.2. The recommended location for a LWCO on gas hot water boilers is above the boiler, in the supply piping. The minimum safe water level of a water boiler is at the uppermost top of the boiler; that is, it must be full of water to operate safely.3. Typically, in residential applications, a probe type LWCO is used instead of a float type, due to their relative costs and the simplicity of piping for aprobe LWCO.Figure 7: Recommended Piping for CombinationHeating & Cooling (Refrigeration) Systems Figure 8: Recommended Probe LWCO Location134. Piping and fittings required to install LWCO are field supplied .5. When constructing a piping tree to install LWCO select fittings (tees, elbows etc) and nipples to have the same size (NPT) as boiler supply connection. At minimum, 1-1/4” tee with ¾” branch outlet isrequired to connect the probe LWCO to the supply piping. See Figure 8. DO NOT REDUCE THE SIZE OF NEAR BOILER SUPPLY FITTINGS AND NIPPLES .6. Installation of manual shutoff valve located above the LWCO and the boiler is recommended to allow servicing. Thus LWCO probe can be removed for inspection without draining the heating system. An annual inspection of the probe is recommended.7. The presence of water covering properly installed LWCO probe will cause the normally open contact of the LWCO to close, thus providing continuity of the 24 v AC service to the boiler gas valve. When water level drops below probe, LWCO contact opens up breaking 24v supply to gas valve and preventing the boiler to fire.8. 2012 compliant Series 2 gas hot water boilers have a “plug-in” provision in factory wiring that will accept optional 24v AC probe LWCO harness connector. The optional LWCO kit (P/N 104083-01) includes 24v AC probe LWCO, harness and Instructions addressing piping, wiring and testing after installation.IV. BOILER WATER PIPING (continued)Figure 9: Recommended Auxiliary Limit LocationC. OPTIONAL AUxILIARY LIMIT INSTALLATION1. Some jurisdictions may require the use of anAuxiliary Limit control with a hot water boiler as a redundant safety control.2. The recommended location for an Auxiliary Limit on gas hot water boilers is in the supply piping. See Figure 9 for recommended location.3. Piping and fittings required to install an Auxiliary Limit are field supplied .4. When constructing a piping tree to install anAuxiliary Limit select fittings (tees, elbows etc) and nipples to have the same size (NPT) as boiler supply connection. At minimum, 1-1/4” tee with 1/2”branch outlet is required to install the limit well into the supply piping. See Figure 9. DO NOT REDUCE THE SIZE OF NEAR BOILER SUPPLY FITTINGS AND NIPPLES .5. When boiler water temperature reaches or exceeds Auxiliary Limit setting, the limit normally closed contact will open, thus interrupting the 24 v AC service to the boiler gas valve. When boiler water temperature drops below limit differential, limit contact closes restoring 24v supply to gas valve and allowing the boiler to fire.6. Gas hot water boilers equipped with Intelligent hydronic Control have a “plug-in” provision in factory wiring that will accept optional 24v AC Auxiliary Limit harness connector. The optional Auxiliary Limit kit (P/N 103696-01) includes 24v AC Auxiliary Limit, Well, harness and Instructions addressing wiring and testing after installation.14Figure 10: Blocked Vent SwitchInstallation DiagramA. INSTALL DRAFT hOOD without modification onoutlet of flue collector (See Figure 1). Secure with sheetB. INSTALL BLOCkED vENT SWITChThe blocked vent switch assembly shipped taped to the top of the boiler includes a power cord and a switch attached to a mounting bracket. The mounting bracket has a three tooth staggered comb stamping at one end with a #10 sheet metal screw in the center tooth.1. Untape the blocked vent switch assembly from the top of the boiler and uncoil the power cord.2. Blocked vent switch power cord (black and black with white stripe wires) is attached to vent damper harness with wire ties. The length of the cord is sufficient to reach the blocked vent switch installed at the left side of the draft hood skirt (see Figure 10). However, if required, use flat blade screwdriver to dislodge black strain relief bushing, securing the harness to boiler left side jacket, to adjust the length as needed.3. Position the mounting bracket (with switch attached) onto the lower edge of the draft hood skirt by locating the center tooth (with the #10 sheet metal screw) on the outside and the other two teeth inside the draft hood skirt. See Figure 10.4. Slide the mounting bracket up tight against the lower edge of the draft hood skirt, so that the #10 sheet metal screw is above the skirt's stiffening rib.5. Secure the bracket in this position by tightening the #10 sheet metal screw against the outer surface of the draft hood skirt.6. If required, reinsert the excess power cord through the jacket side panel hole to take the slack out of the wires running to up to the switch and vent damper.7. Reposition the strain relief bushing around the power cord at the jacket side panel, pinch the two halves of the bushing together, and snap it back into the hole in the jacket side panel to secure the power cord to the jacket.8. Be sure the power cord, mounting bracket, andswitch are secure and located as shown in Figure 10.V. VENTINGC . INSTALL vENT DAMPEROPEN ThE vENT DAMPER CARTON and remove the Installation Instructions. READ ThE INSTALLA-TION INSTRUCTIONS ThOROUGhLY before proceeding.The automatic gas control valve supplied on each Series 2® boiler provides the redundancy referenced inthe vent damper Installation Instructions.15Figure 11: Plug-in Damper Installation1. The vent damper must be the same size as the outlet of the Draft hood supplied with the boiler (see Figure 1). Unpack the damper carefully - DO NOT FORCE IT CLOSED! Forcing the damper may damage the gear train and void the warranty.2. Mount the vent damper assembly after the draft hood, as close to the draft hood as practicable without modification to the draft hood or vent damper. (Refer to Figure 11 and to instructions packed with the vent damper for specificinstructions). This is a must for the wiring harness to fit and the damper position indicator to be visible to3.

All other sizes - Install vent connector from vent damper oulet to chimney.3. vent installation shall be in accordance with local building codes; or the local authority havingjurisdiction; or the National Fuel Gas Code, ANSI Z223.1/NFPA 54; or the Standard for Chimneys, Fireplaces, vents, and Solid Fuel Burning Appliances, ANSI/NFPA 211. Both of theaforementioned standards, ANSI Z223.1 and ANSI/NFPA 211, specify Type B and Type L double wall metal vents and fire clay tile lined masonry chimneys as suitable chimney constructions for Category I, draft hood equipped appliances, such as this Series 2® boiler. Both standards prohibit the use of unlined masonry construction as a chimney, with the exception in ANSI Z223.1/NFPA 54 that "Where permitted by the authority having jurisdiction, existing chimneys shall be permitted to have their use continued when an appliance is replaced by an appliance of similar type, input rating, andefficiency." ANSI/NFPA 211 prohibits the use of single wall metal vent as a chimney, while ANSI Z223.1 allows it under very restrictive conditions. In Canada refer to the Natural Gas and LP Installation Code, CAN/CSA-B149.1.4. Do not connect into same leg of chimney serving an open fireplace.5. Inspect chimney for obstructions or restrictions and remove. Clean chimney if necessary.V. VENTING (continued)Figure 12: Typical Vent Installation6. vent pipe to chimney must not be smaller than outleton draft hood or damper. Although single wall ventpipe may be used, Type B is recommended. Theventing system must be arranged so that only theboiler is served by the damper device. Installationper paragraph (C) complies with this provision.7. Where two or more appliances vent into a commonvent, the area of the common vent should at leastequal the area of the largest vent plus 50% of thearea in the additional vents. Do not connect the vent of this appliance into any portion of mechanicaldraft system operating under positive pressure.8. vent pipe should have the greatest possible initialrise above the draft hood consistent with the headroom available and the required clearance fromadjacent combustible building structure. vent Pipeshould be installed above the bottom of chimney toprevent blockage.9. vent pipe should slope upward from draft hood tochimney not less than one inch in four feet.

ER2-I&S-04Swimming Pool Heaters 150,000 - 399,999 Btu/hr ModelsYour conventionally vented gas unit must have a supply of fresh air circulating around it during burner operation for proper gas combustion and proper venting.Heat exchangers and headers damaged by freezing are not covered by warranty.Refer to the WINTERIZING section.The following safety rules must be observed while operating a spa or hot tub.1.Spa or hot tub water temperatures should never exceed 104ºF (40ºC). A temperature of 100ºF (38ºC) is considered safe for a healthy adult. Special caution is suggested for young children.2.Drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness which could lead to unconsciousness and subsequently result in drowning.3.Pregnant women beware! Soaking in water above 102ºF (39ºC) can cause fetal damage during the first three months of pregnancy (resulting in birth of brain-damaged or a deformed child). Pregnant women should observe the 100ºF (38ºC) maximum rule.4.Before entering the spa or hot tub, users should check the water temperature with an accurate thermometer; spa or hot tub thermostats may err in regulating water temperatures by as much as 4º Fahrenheit (2ºC).5.Persons with a medical history of heart disease, circulatory problems, diabetes or blood pressure problems should obtain their physician's advice before using spas or hot tubs.SPA AND HOT TUB SAFETYPREVENTION OF FREEZINGƽWARNING226Maximum Capacity of Pipe in Thousands of Btu/hr per hour for gas pressures of 14 Inches Water Column (0.5 PSIG) or less and a pressure drop of 0.5 Inch Water Column (Based on NAT 1025 Btu/hr per Cubic Foot of Gas and 0.60 Specific Gravity). 39 Alternate Piping ConnectionsThe corrosive level of pool water can also be measured by the Langlier Saturation Index. This index is calculated by a formula which uses operating temperatures, total alkalinity, pH, calcium hardness and total dissolved solids. The optimum Saturation Index value is zero. A negative value indicates a corrosive condition. Your pool/spa dealer can provide additional data and equipment to make this measurement if a problem exists. TubesThis pool heater is especially designed to operate without accumulation of scale in the heat exchanger, even in very hard water. Periodic inspections of the tubes should be made to be sure that no scale is accumulating. Water piping should be disconnected at the flanges. The front header can be removed to inspect the tubes. A scale deposit of paper thickness is normal. Heavier deposits should be cleaned out. If scale is found in the tubes, THE CAUSE SHOULD BE FOUND AND CORRECTED. Removal and cleaning of the heat exchanger must be performed by a qualified serviceman or installer.The probable cause is improper water chemistry. Check the following possible causes:1. High pH.2. Improper adjustment of an external bypass.3. Inadequate pump flow.Always be sure that the filter pump is in good operating condition and runs continuously when the pool heater is in operation.Heat exchangers and headers damaged by freezing are not covered by warranty. If equipment is subject to freezing temperature, the following precautions must be observed. Although this pool heater is CSA design certified for outdoor installations - such installations are not recommended in areas where pool heater will be operated in the winter months and the danger of freezing exists. Proper freeze protection must be provided for outdoor installations, pool heaters installed in unheated mechanical rooms or where temperatures may drop to the freezing point or lower. If freeze protection is not provided for the system, a low ambient temperature alarm is recommended for the mechanical room. Damage to the pool heater by freezing is non-warrantable.1.Pump Operation - MOST IMPORTANT- This pool heateris designed for continuous operation of the filter system pump when the burners are firing. If the system pump does not run continuously an additional pump must be installed to provide constant circulation through the unit. The constant flow of warm pool water can help prevent freezing.2.Location - Indoor pool heaters must be located in a roomhaving a temperature safely above freezing [32°F(0°C)]. 3.Caution - A mechanical room operating under a negativepressure may experience a downdraft in the flue of a pool heater which is not firing. The cold outside air pulled down the flue may freeze a heat exchanger. This condition must be corrected to provide adequate freeze protection.4.Outdoor Pool Heater Installation - Use extreme caution toprevent freezing. A snow screen should be installed to prevent snow and ice accumulation around the pool heater or its venting system.5.Shut-down and Draining - If for any reason the pool heater isto be shut off when temperatures may be below 35ºF (2ºC), you must winterize the unit:(a)Shut off gas supply.(b)Shut off water supply.(c)Shut off electrical supply.(d)Remove the lower side jacket panel below thewater connections (Figure59).(e)Locate the three (3) drains on the bottom of thefront header (Figure 60).(f)Open all three (3) drains and allow the heatexchanger to drain completely. Leave drains openuntil Spring. Drain the pump and related piping.FIG. 60 Front Header- Bottom View。
