orless. You may not know all the following safety precautions which can protect both you and your family from an accident.
Read them carefully now, then review them point by point with the members of your household. Someday when there may not
be a minute to lose, everyone's safety will depend on knowing exactly what to do. If, after reading the following information,
you feel you still need more information, please contact your gas supplier.
LP-GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas.
That's your signal to go into immediate action!
• Donotoperateelectricswitches,lightmatches,useyourphone.Donotdoanythingthatcouldignitethegas.
• Geteveryoneoutofthebuilding,vehicle,trailer,orarea.DothatIMMEDIATELY.
• Closeallgastankorcylindersupplyvalves.
• LP-Gasisheavierthanairandmaysettleinlowareassuchasbasements.Whenyouhavereasontosuspectagasleak,keepout
ofbasementsandotherlowareas.Stayoutuntilreghtersdeclarethemtobesafe.
• Useyourneighbor'sphoneandcallatrainedLP-Gasservicepersonandtheredepartment.Eventhoughyoumaynotcontinueto
smellgas,donotturnonthegasagain.Donotre-enterthebuilding,vehicle,trailer,orarea.
• Finally,lettheservicemanandreghterscheckforescapedgas.Havethemairouttheareabeforeyoureturn.Properlytrained
LP-Gasservicepeopleshouldrepairtheleak,thencheckandrelightthegasapplianceforyou.

can smell the odorant in propane.Smokingcandecreaseyourabilitytosmell.Beingaroundanodorforatimecanaffectyoursen-
sitivityorabilitytodetectthatodor.Sometimesotherodorsintheareamaskthegasodor.Peoplemaynotsmellthegasodorortheir
mindsareonsomethingelse.Thinkingaboutsmellingagasodorcanmakeiteasiertosmell.
The odorant in LP-gas is colorless, and it can fade under some circumstances.Forexample,ifthereisanundergroundleak,the
movementofthegasthroughsoilcanltertheodorant.OdorantsinLP-Gasalsoaresubjecttooxidation.Thisfadingcanoccurifthere
isrustinsidethestoragetankorinirongaspipes.
Theodorantinescapedgascanadsorborabsorbontoorintowalls,masonryandothermaterialsandfabricsinaroom.Thatwilltake
someoftheodorantoutofthegas,reducingitsodorintensity.
LP-Gasmaystratifyinaclosedarea,andtheodorintensitycouldvaryatdifferentlevels.Sinceitisheavierthanair,theremaybemore
odoratlowerlevels.Alwaysbesensitivetotheslightestgasodor.Ifyoudetectanyodor,treatitasaseriousleak.Immediatelygointo
actionasinstructedearlier.
SOME POINTS TO REMEMBER
• Learn to recognize the odor of LP-gas.YourlocalLP-GasDealercangiveyoua"ScratchandSniff"pamphlet.Useittondout
whatthepropaneodorsmellslike.IfyoususpectthatyourLP-Gashasaweakorabnormalodor,callyourLP-GasDealer.
• Ifyouarenotqualied,donotlightpilotlights,performservice,ormakeadjustmentstoappliancesontheLP-Gassystem.Ifyouare
qualied,consciouslythinkabouttheodorofLP-Gaspriortoandwhilelightingpilotlightsorperformingserviceormakingadjust-
ments.
• Sometimesabasementoraclosed-uphousehasamustysmellthatcancoveruptheLP-Gasodor.Donottrytolightpilotlights,
performservice,ormakeadjustmentsinanareawheretheconditionsaresuchthatyoumaynotdetecttheodoriftherehasbeen
aleakofLP-Gas.
• Odorfade,duetooxidationbyrustoradsorptiononwallsofnewcylindersandtanks,ispossible.Therefore,peopleshouldbe
particularlyalertandcarefulwhennewtanksorcylindersareplacedinservice.Odorfadecanoccurinnewtanks,orreinstalledold

If you have any question about the gas odor, call your LP-gas dealer. Aperiodic sniff test of the LP-gas is a good safety

CAUTION
If one of the procedures results in pressures in excess of
1/2 psig (14" w.c.) (3.5 kPa) on the stove gas valve, it will
result in a hazardous condition.
Checking Manifold Pressure
Both Propane and Natural gas valves have a built-in pressure
regulatorinthegasvalve.Naturalgasmodelswillhaveamanifold
pressureofapproximately3.5"w.c.(.871kPa)formaximuminputor

Propanegasmodelswillhaveamanifoldpressureapproximately

Inhighwindconditions,nearbytrees,adjoining rooflines, steep
pitchedroofs,andothersimilarfactorscanresultinpoordraft,or
down-drafting.Inthesecases,increasingtheventheightmaysolve
thisproblem.
Whenterminatingtheventcapnearanexteriorwalloroverhang,
maintainminimumclearancesasshowninFigure 20.
General Maintenance
Conduct an inspection of the venting system semi-annually.
Recommendedareastoinspectareasfollows:
1. Check areas of the venting system which are exposed to
the elements for corrosion. These will appear as rust spots
orstreaksand,inextremecases,holes.Thesecomponents
shouldimmediatelybereplaced.
2. Removethecapandshineaashlightdownthevent.Remove
anybirdnestsorotherforeignmaterial.
3. Checkforevidenceofexcessivecondensate,suchaswater
dropletsformingintheinnerlinerandsubsequentlydripping
outatjoints.Continuecondensatecancausecorrosionofcaps,
pipeandttings.Itmaybecausedbyhavingexcessivelateral
runs,toomanyelbowsandexteriorportionsofthesystembeing
exposedtocoldweather.
4. Inspectjointstoverifythatnopipesectionsorttingshavebeen
disturbedand,consequently,loosened.Also,checkmechanical
supports,suchaswallstrapsorplumbers'tapeforrigidity.
Ventingterminalshallnotberecessedintoawallorsiding.
Aremovablepanelorothermeansmustbeprovidedintheenclosure
forvisualinspectionoftheueconnection.
Installing the Vent System in a Chase
A chase is a vertical box like structure built to enclose the gas
applianceand/orit'sventsystem.Verticalventrunsontheoutsideof
abuildingmaybe,butarenotrequiredtobeinstalledinsideachase.

Installing Support Brackets
AhorizontalpipesupportMUSTBEusedforeach3feetofhorizontal
run.Thepipesupportsshouldbeplacedaround65/8inchdiameter
pipeandnailedinplacetoframingmembers.ThereMUSTBEa2
inchclearancetocombustiblesabove65/8inchdiameterpipeand
elbowsand1inchclearanceonbothsidesandbottomof65/8inch
tocombustiblesonallhorizontalpipesectionsandelbows.
Verticalrunsofthisventsystemsmustbesupportedevery4feet
abovetheappliance ue outlet by wall brackets attached to the
65/8inchventpipeandsecuredwithnailsorscrewstostructural
framingmembers.
Note:Wheninstallingthisventsysteminachase,itisalwaysgood
buildingpractice to insulatethe chase asyouwould theoutside
wallsofyourhome. This is especially importantforcoldclimate
installations. Upon completion of building your chase framing,
installtheventsystembyfollowingtheinstructionsinthismanual.
Remember to build the chase large enough so that minimum
clearanceofcombustiblematerials(includinginsulation)tothevent
systemaremaintained.
Vertical Through the Roof Applications
YourGasStovehasbeenapprovedfor
a) Verticalinstallationsupto40feetofventrun
b) Two sets of 45degree elbow offsets within these vertical
installations.From0toamaximumof8feetaventpipecanbe
usedbetweenelbows.
c) Wallstrapsmustbeusedtosupportoffsetpipeevery4feet.
Thisapplicationswillrequirethatyourstdeterminetheroofpitch
andusetheappropriateventingcomponents.
Reassembly and Resealing Vent-Air Intake System
Attachventpipetoapplianceairdropwithfour1/2"hex-headscrews
inposition,replaceverticalandhorizontalpipelengths,elbowsand
horizontalorverticalterminationkit.
Allventsystemcomponentslockintoplacebyslidingtheconcentric
pipe section with four  equally spaced interior beads onto the
appliancecollar or previously installed component end with four
equallyspacedindentedsections.Whentheinternalbeadsofeach
starting65/8inchouterpipelineup,rotatepipesectionclockwise
90°(approximately3inches).Theventpipeisnowlockedtogether.
Continuereplacingcomponentspertheventsystemconguration.
Becertainthateachsucceedingventcomponentissecurelytted
andlockedintotheprecedingcomponentintheventsystem.
