Critical Considerations

Mr.Heaterisasuspendedheater.Therefore,itsstability,

flexibility,andsafetyareveryimportant.Beforestarting

installation,besurethesystemcanmeetthefollowing

requirements.

• Maintainspecifiedclearancestocombustibles,andsafe

distancefromtheheat-sensitivematerial,equipmentand

workstations.

• Thestatedclearancestocombustiblesrepresent

asurfacetemperatureof90°F(30°C)aboveroom

temperature.Buildingmaterialswithlowheattolerance

(suchasplastic,vinylsiding,canvas,etc.)maybesubject

todegradationatlowertemperatures.Itistheinstallers

responsibilitytoassurethatadjacentmaterialsare

protectedfromdegradation.

• Provideasuspensionwithverticallengthofchainor

swingingrodwhichhasatleast2inchesofhorizontal

travelforeachburnerinastraightrun.Besurethe

suspensionsystemissufficientlyflexibletoaccommodate

thermalexpansionwhichoccursasthesystemheatsup

(seeFigure6onpage12).

• Provideaccesstoburnersforservicing,preferableon

bothsides,aboveandbehindtheburnerforremoval.

• Provideaminimumof18inchesofclearancebetween

burnersandbuildingwalls.(Alwaysobserveminimum

clearancestocombustibles.)

• Besuretheheaterhasadownwardpitchofone-half

inchper20feetawayfromtheburner.

• Providesignsinstorageareastospecifymaximum

stackingheighttomaintainrequiredclearancesto

combustibles.

• Planlocationsupports(seeFigure2A-Fstartingonpage

8).Locateasupportnearallelbows.

• Theinstallationmustconformwithlocalbuildingcodes

orintheabsenceoflocalcodes,withtheNationalFuel

GasCode,ANSIZ223.1/NFPA54ortheNaturalGas

andPropaneInstallationCode,CSAB149.1.

• Ifanexternalelectricalsourceisutilized,theheater,
