This autonomous agreement, which receives the European Commission’s financial support, is based on a Good Practices Guide. The requirements of the Agreement camehttp://www.nepsi.eu and provide useful Information and guidance for the handling of products containing respirable crystalline silica. Literature references are available on request from EUROSIL, the European Association of Industrial Silica Producers.Prolonged and/or massive exposure to respirable crystalline silica-containing dust may cause silicosis, a nodular pulmonary fibrosis caused by deposition in the lungs of fine respirable particles of crystalline silica.In 1997, IARC (the International Agency for Research on Cancer) concluded that crystalline silica inhaled from occupational sources can cause lung cancer in humans. However it pointed out that not all industrial circumstances, nor all crystalline silica types were to be incriminated. (IARC Monographs on the evaluation of the carcinogenic risks of chemicals to humans, Silica, silicates dust and organic fibers, 1997, Vol. 68, IARC, Lyon, France.)In June 2003, SCOEL (the EU Scientific Committee on Occupational Exposure Limits) concluded that the main effect in humans of the inhalation of respirable crystalline silica dust is silicosis. "There is sufficient information to conclude that the relative risk of lung cancer is increased in persons with silicosis (and, apparently, not in employees without silicosis exposed to silica dust in quarries and in the ceramic industry. Therefore preventing the onset of silicosis will also reduce the cancer risk…” (SCOEL SUM Doc 94 - final, June 2003).So there is a body of evidence supporting the fact that increased cancer risk would be limited to people already suffering from silicosis. Worker protection against silicosis should be assured by respecting the existing regulatory occupational exposure limits and Implementing additional risk management measures where required.Health & Safety Executive: Detailed reviews of the scientific evidence on the health effects or crystalline silica have been published by HSE (Health and Safety Executive, UK) in the Hazard Assessment Documents EH75/4 (2002) and EH75/5 (2003). The HSE points out on its website that Workers exposed to fine dust containing quartz are at risk of developing a chronic and possibly severely disabling lung disease known as "silicosis”. In addition to silicosis, there is now evidence that heavy and prolonged workplace exposure, to dust containing crystalline silica can lead to an increased risk of lung cancer. The evidence suggests that an increased risk of lung cancer is likely to occur only in those workers who have developed silicosis.Disclaimer: The Information in this Safety Advisory Document was obtained from sources which we believe are reliable, but no warranty or representation as to its accuracy or completeness is hereby given.

Designation:A341/A341M–00(Reapproved2005)Standard Test Method forDirect Current Magnetic Properties of Materials Using D-C Permeameters and the Ballistic Test Methods1This standard is issued under thefixed designation A341/A341M;the number immediately following the designation indicates the year of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1This test method provides dc permeameter tests for the basic magnetic properties of materials in the form of bars,rods, wire,or strip specimens which may be cut,machined,or ground from cast,compacted,sintered,forged,extruded, rolled,or other fabricated materials.It includes tests for determination of the normal induction under symmetrically cyclically magnetized(SCM)conditions and the hysteresis loop(B-H loop)taken under conditions of rapidly changing or steep wavefront reversals of the direct current magneticfield strength.1.2This test method shall be used in conjunction with Practice A34/A34M.1.3This test method covers a range of magneticfield strength in the specimen from about0.05Oe[4A/m]up to above5000Oe[400kA/M]through the use of several permeameters.The separate permeameters cover this test region in several overlapping ranges.1.4Normal induction and hysteresis properties may be determined over theflux density range from essentially zero to intrinsic saturation for most materials.1.5Recommendations of the useful magneticfield strength range for each of the permeameters are shown in Table12. Also,see Sections3and4for general limitations relative to the use of permeameters.1.6The symbols and abbreviated definitions used in this test method appear with Fig.1and in appropriate sections of this document.For the official definitions,see Terminology A340. Note that the termflux density used in this document is synonymous with the term magnetic induction.1.7The values and equations stated in customary cgs-emu and inch-pound or SI units are to be regarded separately as standard.Within this standard,SI units are shown in brackets except for the sections concerning calculations where there are separate sections for the respective unit systems.The values stated in each system may not be exact equivalents;therefore, each system shall be used independently of the bin-ing values from the two systems may result in nonconformance with this standard.1.8This standard does not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1ASTM Standards:3A34/A34M Practice for Sampling and Procurement Test-ing of

No.74,pg.2695NIST Scientific Paper117,SPBTA53.Significance and Use3.1Permeameters require the use of yokes to complete the magnetic circuit and are therefore inherently less accurate than ring test methods.Refer to Test Method A596/A596M for further details on ring test methods.However,when testing certain shapes as bars or when magneticfield strength in excess of200Oe[15.9or more kA/m]are required,permeameters are the only practical means of measuring magnetic properties.1This test method is under the jurisdiction of ASTM Committee A06on Magnetic Properties and is the direct responsibility of Subcommittee A06.01on Test Methods.Current edition approved Nov.1,2005.Published November2005.Originally approved st previous edition approved in2000as A341/A341M–00.2The boldface numbers in parentheses refer to a list of references at the end of this standard.3For referenced ASTM standards,visit the ASTM website,,or contact ASTM Customer Service at service@.For Annual Book of ASTM Standards volume information,refer to the standard’s Document Summary page on the ASTM website.4Available from American National Standards Institute(ANSI),25W.43rd St., 4th Floor,New York,NY10036.5Available from National Institute of Standards and Technology(NIST),100 Bureau Dr.,Stop3460,Gaithersburg,MD20899-3460.Copyright©ASTM International,100Barr Harbor Drive,PO Box C700,West Conshohocken,PA19428-2959,United States.3.2This test method is suitable for specification acceptance,service evaluation,research and development and design.3.3When the test specimen is fabricated from a larger sample and is in the same condition as the larger sample,it may not exhibit magnetic properties representative of the original sample.In such instances the test results,when viewed in context of past performance history,will be useful for judging the suitability of the material for the intended application.4.Interferences4.1In general,permeameters do not maintain a uniform magnetic field in either the axial or radial directions around the test specimen.The field gradients in both of these directions will differ in the various permeameters.Also the H -sensing andB -sensing coils of the different permeameters are not identical in area,in turns,or in length or identically located.Although test specimens are prepared to have uniform physical cross section,they may have undetected nonuniform magnetic prop-erties radially or axially along the specimen length adjacent to the H or B coils.Some permeameters may also introduce clamping strains into the test specimen.For the above reasons test results obtained on a test specimen with one type per-meameter may not agree closely with those obtained on the same test specimen using another type of permeameter.5.Apparatus5.1Because of the differences in physical construction of the various permeameters listed in Table 1,no standard list of components is given.When used with a particular type of permeameter,the components should conform to the general requirements listed below.A basic schematic of a permeameter is shown in Fig.1.5.2Permeameter —The particular permeameter used shall be of high quality construction.The yokes should be made of high permeability alloy such as oriented or nonoriented silicon iron or nickel-iron alloy,although low carbon steel or iron is acceptable in certain instances.The preferred yolk dimensions are listed in the appended references (see Table 1).Deviations from these dimensions should be such that the yolk is operating at or below the point of maximum permeability for the highest test flux densities encountered.Yoke construction may consist of either stacked laminations or stripwound C cores suitably bolted or adhesive bonded together.5.3Power Supply —The magnetizing current shall be sup-plied by either storage batteries or dc power supplies.Bipolar programmable linear power supplies have been found to be well suited for this use.The source of dc current must be stable,have negligible ripple and be capable of quickly returning to the stable state after switching.When programmable power supplies are used,either digital or analog programming signals are permissible provided that equal but opposite polarity current cycling is possible.5.4Main-Current-Control Rheostats,R 1—When used,these rheostats must have sufficient power rating and heat-dissipating capacity to handle the voltage and largest testTABLE 1PermeametersPermeameterUseful Magnetic Field Strength Range AH Measuring Device BReluctance CompensationMagnetizing Coil Surrounds

the test currents to those required for the lowest magneticfield strength to be used.5.5Hysteresis-Current-Control Rheostats,R2—When used, these rheostats must have the same characteristics as the main-current control rheostats.5.6Main-Current Ammeter,A1—Magnetizing current mea-surement shall be conducted using a digital ammeter or combination of a digital voltmeter and precision shunt resistor with an overall accuracy of better than0.25%when the magneticfield strength will be determined from the current.In those permeameters where the magneticfield strength is determined by other means,such as Hall probes or H coils, lower accuracy analog instruments can be used.In such permeameters,the ammeter is used to prevent excessive currents from being applied and,based on past experience,to roughly establish the required magneticfield strength.5.7Hysteresis-Current Ammeter,A2—The requirements of 5.6shall apply.In general,a separate ammeter is not required.5.8Reversing Switch,S1—When nonprogrammable dc cur-rent sources such as storage batteries are used,a current reversing switch is required.The reversing switch should be either a high quality knife switch,mechanical or electrical solenoid-operated contractors or mercury switches having high current rating and the ability to maintain uniform contact resistance of equal magnitude in both current directions. Switches with contact bounce or other multiple contacting behavior on make or break must be avoided.Because of the presence of leakage currents in the open condition,solid state relays are not permitted.5.9Hysteresis Switch,S2—This single pole switch must conform to the same requirements as the reversing Switch,S1.5.10Integrator,F—Because of their superior accuracy, stability,and ease of operation,electronic charge integrators are the preferred means of measuring magneticflux.Integra-tors using either operational amplifier and capacitor feedback (analog integrator)or pulse counting are permitted.The accu-racy of the integrator must be better than1%full scale.If analog display meters are used to read the value offlux,the measurement should be made on the upper two-thirds of the scale.Analog integrators must have drift adjust circuitry and the drift should not exceed100Maxwell-turns[10−6Wb-turns] per minute on the most sensitive range.It is also desirable that the integrator have appropriate scaling circuitry to permit direct reading of eitherflux(f)orflux density(B).Ballistic galva-nometers or moving coilfluxmeters are permitted provided the 1%full-scale accuracy requirement is met.Such devices require additional circuitry not shown in Fig.1.Details may be found in the appropriate references appended to this test method.5.11B Coils—Prewoundfixedflux sensing coils are often used.When used,the cross-sectional area enclosed by the secondary winding and number of turns must be known to be better than0.5%.5.12Magnetic Field Strength Measuring Devices—Certain permeameters do not or cannot use the magnetizing current to determine the magneticfield strength accurately.Such per-meameters instead use stationary H coils,flip coils,or Hall probes.When such devices are used,they shall be capable of determining the apparent magneticfield strength to accuracy of 1.0%or better.6.Test Specimens6.1Test specimen area shall normally be determined from mass,length,and density as indicated in9.1and10.1.When the test specimen is machined or ground to have a very smooth surface,the physical dimensions obtained from micrometer measurements may be used to calculate the cross-sectional area.6.2Test specimens in bar form may be of round,square,or rectangular cross-sectional shape.In some permeameters the bar specimen may be a half round or any shape having a uniform cross-sectional area.Certain permeameters must have a good magnetic joint between the ends of the test specimen and the permeameter yoke or pole faces.Pole shoes may be necessary to create this joint.Generally,to achieve a good magnetic joint,the test specimen must be of square or rectangular cross section and must be machined or ground to have straight and parallel surfaces.For permeameters using specimens butted to pole pieces,the specimen ends must be smooth and parallel.6.3When the material is inflat-rolled form and is to be evaluated as half transverse-half longitudinal,the specimen shall be sheared to have strips in multiples of four in accor-dance with Table2.When material is to be evaluated in one direction,it shall conform to this table or to the requirements for best test quality in a particular permeameter.For gages No. 33and thinner,the cross-sectional area shall be not less than 0.31in.2[200mm2]and not more than0.62in.2[400mm2].6.4When the test specimen for strip materials is to be half transverse and half longitudinal,the strips shall be positioned to be composed of alternately transverse and longitudinal throughout the specimen and a transverse strip shall be placed adjacent to the permeameter’s yoke or pole face.6.5For full testing accuracy,the length and size of the test specimen must meet the requirements of the permeameter being used.Generally,for most permeameters,a test specimen length of10in.[0.254m]or more is required.Shorter specimens with some permeameters will require the use of pole-piece extensions,and may cause a reduction in testing accuracy.Other permeameters are designed for short speci-mens without loss of testing accuracy.6.6All test specimen forms shall be cut,machined,or ground to have a uniform cross-sectional area along the active length of the test specimen.The cross-sectional area shall be sufficiently uniform so that its nonuniformity will not materi-ally affect the accuracy of establishing and measuringflux density in the test sample.6.7When required for development of material properties the test specimen shall have received a stress relief or otherTABLE2Number of Test StripsNominal Thickness GageNumberNumber ofStrips in.mm0.0100to0.02500.254to0.63532to24,incl120.0280to0.04350.711to1.10523to19,incl80.0500and over 1.27and over18and thicker4heat treatment after preparation.This anneal is subject to agreement between manufacturer and purchaser;manufactur-er’s recommendation;or the recommended heat treatment provided by the appropriate ASTM standard for the material. The heat treatment used shall be reported with the magnitude test results.6.8Specimens of permanent-magnetic materials shall be processed before testing in accordance with a procedure acceptable to both manufacturer and purchaser.The processing used shall be reported with the test results.7.Calibration7.1Integrator—Practical operating experience has shown that provided a proper warmup period is allowed,electronic integrators require infrequent calibration and unlike ballistic galvanometers,calibration is not an integral part of this test method.When calibration is required,it can be accomplished with either a mutual inductor or a volt-second source.Because of their traceability to the fundamental units of voltage and time,volt-second sources are the preferred means of calibra-tion.The accuracy of either the mutual inductor or volt-second source must be better than the rated full scale accuracy of the integrator.7.2Fixed B and H Coils—The effective area turns of such search coils can be determined by comparison with a coil of known area turns or by individual calibration in a series of known magnetizingfields.Suchfields can be obtained using either long solenoid electromagnetics or large Helmholtz coil systems.7.3Comparison Permeameters—Certain types of per-meameters such as the Fahy permeameter require a standard specimen of known magnetic properties to derive the relation-ship betweenfield sensor output and true magneticfield strength.Instead of nationally recognized standard specimens, a standard may be developed by mutual agreement between manufacturer and purchaser,and if possible,a referee labora-tory.8.Procedure8.1Most permeameters use a compensating system of magnetizing coils to provide extra magnetomotive force to overcome the reluctance of the yokes and joints in the magnetic circuit.Hence,the detailed operation procedure will vary somewhat with the type of permeameter used.Detailed oper-ating procedures can be found in the references appended to this test method.The procedure listed below is common to all types of permeameters.8.2In Fig.1,the dc power source supplies testing current measured by ammeter A1.Rheostats R1and R2and Switches S1 and S2determine the magnitude and direction of the current as required by various operations.In general,three kinds of switching operations are required in ballistic testing.One is reversal of magnetizing current direction without change of magnitude as required for establishing a cyclic condition and in normal magnetic tests.This is done by throwing Switch S1 from one side to another.A second is reduction of magnitude of magnetizing current without change of direction.This is done by opening Switch S2.The third operation combines reversal of direction of magnetizing current with reduction in magnitude.This is done by simultaneously throwing Switch S1from one side to the other and opening Switch e care to be sure S2 is opened before S1is closed for reversal.When determining the hysteresis loop,Switches S1and S2must be operated to traverse the loop in the same direction between successive measurements so as to preserve the cyclically magnetized state of the test specimen.8.3Before testing,demagnetize the specimen in the per-meameter or by some other acceptable means.Demagnetize by first establishing a magneticfield strength sufficiently large to cause theflux density in the test specimen to reach a point well above the knee of the magnetization curve.Then while continuously operating the reversing switch at half-second or longer intervals,slowly reduce the magnetizing current to zero in small increments.An auxiliary demagnetizing circuit using a time delay relay will make this operation more reproducible and less tedious.8.4To obtain theflux density(B)corresponding to a specific magneticfield strength(H),establish the proper magneticfield strength,cycle the reversing switch several times to establish the symmetrically cyclically magnetized(SCM)condition, zero the integrator and execute the proper switching procedure detailed in8.2.The value of theflux orflux density can then be computed from the integrator reading.Additional test points on the magnetization curve can be obtained without demagneti-zation if they are obtained in ascending order of B or H. Otherwise,it is necessary to demagnetize before additional testing.8.5To obtain the magneticfield strength corresponding to a specificflux density,a procedure similar to8.4is used with the exception that the magneticfield strength must be found by trial and error.If the specifiedflux density is exceeded, demagnetization is usually required before proceeding further unless operating at very lowflux densities.8.6Electronic integrators do not determineflux densities directly,rather the change influx linkages(N2Df)is measured. This result is converted to changes influx density by division by the specimen cross-sectional area A and number of second-ary turns N2.To determine the actual value offlux density,the starting or reference points must be known.In the case of magnetization curve measurements,it is customary to zero the integrator and measure the change influx density for a fully reversed change in magneticfield strength.In this instance,the true value offlux density is one half of the total change influx density.For hysteresis loop determination,the integrator is zeroed at the point of maximum magneticfield strength.The resulting change influx density is equal to the difference influx density between the point of maximum magnetization force and the point corresponding to the hysteresis loop measure-ment magneticfield strength.9.Calculation(Modified cgs Units)9.1The sample cross-sectional area shall normally be de-termined from test specimen mass,length,and density using the equation:A5m/d

larger than the test specimen cross-sectional area;when this occurs,a correction for airflux in the B coil is required.This correction shall be made as shown in9.2.1through9.2.3.9.2.1The geometric correction factor is given by:K5~a2A!/A(2) where:a=cross-sectional area of test(B),coil,cm2,andA=cross-sectional area of test specimen,cm2.9.2.2The correctedflux density is given by:B5B obs2K G m H(3)

along with the test data:11.1.1Name or type of permeameter used.11.1.2Size and shape of the test specimen.11.1.3Heat treatment or other processing applied to the test specimen before testing.11.1.4When permeability is reported,the corresponding value of either B or H must be reported.11.1.5With hysteresis data,when coercive force,residual flux density,or other specific hysteresis test points are reported, the value of cyclically symmetrical peak magnetizing force or flux density must be reported.11.1.6Whenflux density values are reported,as those for saturationflux density,the corresponding value of magnetizing force must be reported.12.Precision and Bias12.1The reliability of the results of magnetic tests in permeameters depends not only upon the method or apparatus used,but also upon the nature of the specimen.The most common sources of variations in magnetic properties due to the test specimen are:(1)lack of uniformity in permeability along the length of the specimen,(2)mechanical strain,and(3)temperature variations.Variations as a result of these causes are difficult to measure and may be large.12.2In comparing the results of direct-current magnetic tests,it should be recognized that flux density,B ,and magnetic field strength,H ,are independently determined quantities,each of which is separately subject to experimental error.The flux density errors include those caused by nonuniform flux density and nonuniform properties along the specimen length and,when fixed B coils are used,errors caused by imprecise air flux correction.Field distortion in permeameters can be severe around the test specimens and H coils.For this reason,the determination of magnetic field strength in the test specimen is inherently less accurate than the determination of flux density.With some permeameters the use of flip H coils or multiple H coils with extrapolation to the specimen surface or Hall effect devices may improve the accuracy of H determination.How-ever,the field around these devices and the test specimen can be distorted in both the axial and radial directions.To be effective,they must be used in such a manner as to integrate the field around the test specimen and over the same length as that covered by the B coil.The magnitudes of the various errors arepeculiar to the test permeameter and the characteristics of the material under test.For a given set of corresponding measured values of B and H wherein the errors are 6d B and 6d H in B and H ,respectively,the true characteristic curve of the test specimen may lie anywhere within the boundaries of the region defined by the two curves (B +d B )versus (H −d H )and (B −d B )versus (H +d H ).12.3For specimens having a satisfactory degree of unifor-mity,clamped or mounted so as to be free from mechanical strain,and kept at a constant temperature within 5°C,for H greater than 1.0Oe [79.6A/m],the methods may be expected to determine average induction,B ,to a precise of 61%and to determine average magnetic field strength,H ,to the precisions indicated in Table 3.When these values are combined to calculate permeability,µ,its precision may be expected to fall within the limits imposed by the sum of the precisions of measurement for the corresponding B and H values.13.Keywords13.1coercive force;induction;magnetic field strength;magnetic

When installing this fireplace at an eleva-tion above 2000 feet (in the USA), you may need to decrease the input rating by chang-ing the existing burner orifice to a smaller size. Reduce input 4% for each 1000 feet above sea level. Check with your local gas company for proper orifice size identifica-tion and proper orifice for your location. When installing this fireplace at an eleva-tion above 4500 feet (in Canada), check with local authorities.For assistance with any high altitude installa-tion contact DESA International’s Technical Service Department at 1-800-DESA-LOG (1-800-337-2564).TROUBLESHOOTINGVENTINGPROBLEMSMost venting problems are caused by incor-rect vent sizing, improper installation, orinadequate air supply. A preliminary checkfor a field problem might include:•Using a draft meter to determine ifventing system draft meetsmanufacturer’s specifications•Checking the vent sizing according tomanufacturer’s specifications, applianceinput, and venting configuration•Examining the entire venting system forfaults such as disconnected joints fordamaged vent sections•Making sure vent and air openings arenot obstructedIf these procedures do not reveal the source ofthe problem, troubleshooting may includeattention to common venting problems.FLUE GAS SPILLAGESpillage occurs when flue gases cannot exitthe vent system and back up into the dwell-ing. A primary symptom of appliancesequipped with a Vent Safety Shutoff System(flue spill switch) is unexplained applianceshutoffs. Other symptoms of flue gas spillageat the draft hood include condensation onwalls and windows and/or noticeable odors.Spillage may also result in the release ofcarbon monoxide, a colorless, odorless, highlytoxic gas. A simple spillage test can be con-ducted if spillage is suspected. See CheckingGas Connection, pages 13 and 14.CAUSES OF SPILLAGE ANDCORRECTIVE ACTIONIncorrect Vent SizingIf the vent is too small or too short, spillagemay occur. If the vent is too large, excessivedilution air may cool flue gases and reducedraft, causing spillage. The vent cap sizeshould also be checked. Checkmanufacturer’s instructions, appliance in-put rating, and appropriate sizing tables.Venting ConditionLoose joints can affect draft and cause spill-age. “Mashed” vent sections and damagedvent caps can restrict flow and cause spill-age. Examine and replace as needed.ObstructionsSmall animals or birds may get into and blockthe vent or draft hood outlet. Dust, lint, andforeign objects may obstruct air inlets. Re-move obstructions and clean openings.Lateral RunLengthy horizontal or non-vertical runs causeresistance to flow and may reduce draftenough to cause spillage. The pitch of lateralruns can also be a problem; lateral runsshould be pitched 1/4" rise per foot of hori-zontal run from the appliance to the vent.ElbowsToo many elbows cause excessive restric-tion of flow and may result in spillage.Usually, two 90º turns can be tolerated in aproperly sized venting system. More thantwo may cause problems and necessitatechanging the system.Negative Pressure in theDwellingAn extremely tight house may not supplyadequate combustion and venting air. Useof mechanical exhaust such as a dryer ventor range vent may worsen the problem. Anair exchange system must be installed in thedwelling to correct this problem.Flue Gas CoolingVenting exposed to extremely cold tem-peratures or venting of single wall construc-tion loses heat needed to maintain draft;massive masonry chimneys absorb neededheat. If the flue gases cool excessively, draftis reduced and spillage may result. Useproper materials, insulate and protect prop-erly, reline when necessary.Down DraftsIn certain wind conditions and in certainrelationships with nearby structures andobjects, high pressure conditions may affectdraft negatively. Relocate the vent cap, raiseits height, or use an approved high wind cap.1110602212B-VENT FREESTANDING FIREPLACE1060221310602214B-VENT FREESTANDING FIREPLACE10602215106022161060221710602218B-VENT FREESTANDING FIREPLACE10602220B-VENT FREESTANDING FIREPLACE1060222110602222B-VENT FREESTANDING FIREPLACE106022OBSERVED PROBLEMBurner does not light after pilot is lit Delayed ignition burnerBurner backfiring during combustionSlight smoke or odor during initial operation Heater produces a whistling noise when burner is litGlass sootsFireplace produces a clicking/ticking noise just after burners are lit or shut off Remote does not function REMEDY1.Clean burner (see Cleaning andMaintenance, page 21) or replace burner orifice2.Contact local propane/LP or natural gascompany3.Reconnect leads (see Wiring Diagram,page 25)4.Replace thermopile1.Contact local propane/LP or natural gascompany2.Clean burner (see Cleaning and Main-tenance, page 21) or replace burner orifice 1.Clean burner (see Cleaning andMaintenance, page 21) or replace burner orifice2.Replace damaged burner3.Replace gas control1.Problem will stop after a few hours ofoperation1.Turn control knob to LO position andlet warm up for a minute2.Operate burner until air is removed fromline.
