SECTION 2: Planning

Thefollowingcodesandinstructionsshouldbefollowedwhen

planningtheinstallationofthisJETheater.Inadditiontothese

instructions,thewarningsmustbecarefullyadheredtosince

improperinstallationmayleadtopropertydamage,injury,or

death.

National Standards and Applicable

Codes

Gas Codes:

•Thetypeofgasappearingonthenameplatemustbethe

typeofgasused.Installationmustcomplywithlocalcodes

andrecommendationsofthelocalgascompany,andthe

NationalFuelGasCode,ANSIZ223.1–latestrevision,(same

asNFPABulletin54)(theNaturalGasandPropaneInstallation

Code,CSAB149.1)Canadaonly.

•Clearancebetweentheheateranditsventandadjacent

combustiblematerial(whichispartofthebuildingorits

contents)shallbemaintainedtoconformwiththeStandard

forInstallationofGasAppliancesandGasPiping,NFPA-54

/ANSIZ223.1–latestrevision,NationalFuelGasCode(the

NaturalGasandPropaneInstallationCode,CSAB149.1)

Canadaonly.

Hazardous Locations:

Wherethereisthepossibilityofexposuretocombustible

airbornematerialorvapor,consultthelocalFireMarshal,

thefireinsurancecarrierorotherauthoritiesforapprovalof

theproposedinstallation.

Critical Considerations

ThisJETmodel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accesstoburnersforservicing,preferableonboth

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

•Alwaysobserveminimumclearancestocombustibleslocated

onpage4.

•Planlocationsupports(seeFigure2A-Bstartingonpage6).

•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(theNaturalGasandPropane

InstallationCode,CSAB149.1)Canadaonly.

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

installed,mustbeelectricallygroundedinaccordancewith

theNationalElectricalCode,ANSI/NFPA70orcurrent

CanadianElectricalCode,CSAC22.1.

Installation Procedure

Takemaximumadvantageofthebuildingupperstructure,

beams,joists,purlins,etc.,fromwhichtosuspendtheheater.

Thereisnouniquesequenceforinstallationofthetubing.On-

siteobservationwillusuallyrevealalogicalsequence.Beginthe

installationatthemostcriticaldimension.Reflectorsandtubing

canbeinstalledasyoumovealong.Carefullyadjustsystempitch

ateachpositiontoleveltheheater.Pitchdownone-halfinchin

20feet(awayfromburner).

DON’TPressuretestthegaslineusinghighpressure(greater

than½PSIG)withoutclosingthehigh-pressureshutoff

cocks.Failuretodosowillresultindamagetothe

burners.

DO Familiarizeyourselfwithlocalandnationalcodes.

 Developaplannedprocedurewhichwillconserve

materialandlaboronthejob.

 Checktoseethatallmaterialandequipmentisonthe

jobbeforestartinginstallation.

 Allowforthermalexpansionofthetubes.

 Installthegasconnectoronlyasshownininstructions

(seeFigure14&15onpage11).

 Useselftappingscrewswherereflectorsoverlapto

assurethattheydon'tcomeapart.

 Attachreflectorretentionwiretoburnerboxorchain

suspendingburnerbox.Thewirecomesattachedtoone

ofthereflectors.Seeintructionsintubesetfordetails.

 Provide1sq.inchoffreeairopeningtoeach1,000BTU/

hr.ofheaterinput(butnotlessthan100sq.inches)in

IMPORTANT:

•DO NOT draw inlet air from inside the poultry confinement

area.

•If the attic has a slight negative pressure or contaminants

are present in the air, an outside combustion air supply to the

heaters is strongly recommended.

•The pressure switch will not close causing the heater not to

operate if the intake is blocked by insulation in the attic. We

recommend double checking that the intake isn't blocked after

initial installation as well as in betweeen flocks when it is

known that the attic has blown in and loose insulation.

•Always attach your air inlet system to the burner box with

a flexible section. This piece should be free of kinks and as

straight as possible, no more than one 90° bend.
