•Series 200
The 200 series is the same basic electric furnace with more functional options. These furnaces are factory assembled for operation with a 1, 2 or 3 stages thermostat. When used with a multi-stage thermostat the unit will modulate its power depending on the stage calling for heat. The furnace is factory assembled with a three positions switch to manually choose the level of heat if installed with a one stage thermostat. The intermediate modes of heating are detailed in tables 2 and 3 and explained later in this guide. The Series 200 also comes with a low speed fan switch that enables operation of the lowest speed of the motor for continuous ventilation when needed. The Series 200 also has a cooling relay to permit high speed operation when matched with an air conditioning unit. Suffix C indicates operation at 0.5” W.C. at high speed.
•Series 300
Series 300 has the same functionality of series 200 while being equipped with a 120V motor-blower combination. This series also comes with, as standard equipment, a 120V terminal strip enabling connection
of additional equipment such as electronic air filter and/or humidifier. Finally, this series has insulating wool in the blower compartment. As in series 100 and 200, suffix C indicates operation at 0.5’’ W.C. at high speed. Series 300 features an extended capacity with the addition of a 23 KWatt model. Please note that the 23 KWatt model is ONLY offered on Series 300. Finally, Series 300 is also offered with a 1/2HP ECM motor as optional equipment. This motor is a high efficiency (up to 80%) motor that is fully compatible with the standard control scheme of the furnace. ECM models are identified with the ECM suffix.

2.0 Important safety information
• WARNING – BASIC SAFETY WARNINGS
The initial electrical connection and subsequent service MUST be done by a qualified electrician in accordance with this manual AND ELECTRICAL CODES HAVING JURISDICTION IN YOUR AREA .
This unit is intended and approved for use with heating ducts. Use without ducts will result in untested operation that could result in property damage, accident or DEATH.
Disconnect power to the unit before doing any service on the unit. The type of voltage and current used in this furnace are enough to cause serious injury and/or DEATH.
This furnace is not approved or intended for use outside. Use outside voids the warranty.
Do not store gasoline, fuel or any flammable substances near the furnace.
Ask the installer to show you the location of the main disconnect breaker of the furnace.
WARNING – BEST PRACTICES FOR OPTIMAL OPERATION
Make sure that the air filter is always clean and in good working condition and not overly obstructed. An obstructed air filter will result in reduced air flow and higher outlet temperature. Continued operation WITH THE FILTER CLOGGED will drastically reduce the life of the heating elements.
The unit must be inspected once a year by a qualified technician.
Make sure that you have enough clearance in the front and the rear of the unit for service and maintenance. Although the unit is approved for zero clearance on these panels, it is definitely NOT a good practice to do it.
3.0 Installation of the furnace
The return air/ inlet connection is made on the rear of the unit and the supply plenum is connected in the front of the unit. The flanges supplied with the cabinet are 19” X 19” and can accommodate plenums of that size. The cabinet is also large enough so 20” X 20” supply plenums could be attached directly on the furnace. See Figure 1 for details. The unit is approved for installation with zero clearance on all parts of the cabinet including the floor (combustible floor) and also with zero clearance on the walls of the supply plenum. The unit can be installed directly on the floor, on the adjustable legs (included) or suspended to the ceiling with “plumber” straps. Please see figure 2A, 2B and 2C for the different installation configurations. Make sure to leave sufficient clearance in the front of the unit for the electrical connections and electrical service and in the rear of the unit for blower and motor maintenance and service. Please note that the air filter rack can be installed on the right or left side of the unit in addition to the rear (factory position). To change the filter rack position, refer to fig. 3.

Also note that the blower in the rear compartment can be removed by loosening the 4 wing nuts (figure 3) that hold it to the blower supports. The wire is long enough so you can remove the blower from the unit without disconnecting it. CAUTION: when removing the blower, DO NOT remove the blower legs. Loosen the 4 wing nuts and slide the blower out. To replace the blower, position the studs in the slots on the blower legs and fully insert the blower. Be sure to RETIGHTEN the wings nuts after reinstalling the blower. Consult figure 4 for details.
4.0 Electrical connection to the furnace
4.1 240VAC – High voltage

When the cooling thermostat is not calling for cooling:
•The elements are not energized and the blower is on low speed.
•The blower will start at the highest speed.
When the cooling demand is satisfied:
The blower will keep running on low speed.
NOTES:
The power switch has no effect on cooling mode when there is a cooling demand from the thermostat.
If a two stage thermostat is used, remove the jumpers between W1 & W2. If a three stage thermostat is used remove the jumpers between W1 & W2 and between W2 & W3. In this mode the thermostat will automatically control the sequence between the different elements and the motor speeds. In such a case, it is imperative that the power switch be at its maximum position (center position), i.e. 15KW for model 215, 18KW for model 218 and 19KW for model 219.
In the above examples, the operation is similar for models 218, 219, 318 and 319. The three settings are, respectively, 9KW with low speed, 13KW with medium speed and 18KW with medium speed for model 218 and 319 and 9KW with low speed, 14KW with medium speed and 19KW with medium speed for model 219 and 319, 10 KW with low speed, 18 KW with medium speed and 23 KW with medium speed for model 323.
REMEMBER TO VERIFY THE POWER SWITCH POSITION WHEN TROUBLESHOOTING PROBLEMS THAT RELATE TO THE FURNACE NOT SUPPLYING ENOUGH HEAT OR WHEN MEASURING A CURRENT LOWER THAN EXPECTED.
6.0Air flow verification
After the installation, it is CRITICAL that proper air flow be verified. This is done by taking the difference of temperatures (delta T) between the inlet plenum and the supply (warm air) plenum. Take 4 or 5 measurements in the duct and calculate the average for the warm air duct. This temperature differential must be in accordance with the table in section 1.3. If the temperature difference is much higher than table 1, 2 or 3 of section 1.3 for the specified power setting, it is an indication that restriction in the heating system is much larger than normal. This might be caused by an obstruction or a clogged air filter. It is also possible that your house has an abnormally high pressure restriction. In that case it is possible to use the high speed of the blower. To do this, internal connections to the motor must be transferred from the medium speed tap to the high speed tap on the motor. Refer to the electrical diagram. It is strongly recommended that this modification be done by a qualified technician or electrician. Note the Delta T’s in the table below. This information will be very valuable when doing annual maintenance. Please note that the factory settings for the blower are:
•Series 100
o15KW, 18KW and 19KW without cooling coil (0.20” W.C.): medium speed.
o15KW, 18KW and 19KW with cooling coil (0.50” W.C.): high speed.
•Series 200 and 300
o 5 KW and 10KW power setting on Econoplus-215 and 315: low speed.
o9 KW power setting on Econoplus-218, 219, 318 and 319: low speed.

o19 KW power setting on Econoplus-219 and 319: medium speed.
o23 KW power setting on Econoplus-223: medium speed.
o All models with cooling coil (0.5” W.C.): high speed.

7.0Annual maintenance
This electric furnace requires very little maintenance. Nonetheless the following points should be checked annually:
REPLACE the air filter. The model used is a standard 20” X 20” X 1” thick paper air filter found at any hardware store.
Verify the operation of the unit by having the thermostat call for heat. Re-verify the temperature differential (Delta T) between the inlet and outlet plenums. A difference from the initial installation results can be a clue to obstruction problems in the duct system if the delta T is higher but could also be a clue that one or more heating elements are faulty if the delta T is lower.
The blower motor DOES NOT require lubrication.
