2.5HEATERLOCATION

Attention Fluerequirementsmayaffectlocation.Consultsection 7 beforemakingafinaldetermination.

 Usetheminimumclearancesasillustratedinfigure2andthethrowdatamentionedintable1(Technical
Data)todefinewheretolocatetheheater.
 Alsorespecttherecommendedminimumheightasgivenintable
1.

 Forbestresults,theheatershouldbeplacedwithcertainrulesinmind.Alwaysensurethatminimum
clearancesaremaintained.Locatingaunitheaterabovethemaximumrecommendedheightcanresultin
significantairstratification.Whenpossible,heatersshouldbearrangedtoblowtowardoralongexposedwall
surfaces.

Suspendedheatersaremosteffectivewhenlocatedasclosetotheworkingzoneaspossible,butcareshould
beexercisedtoavoiddirectingthedischargedairdirectlyontotheroomoccupants.
 Partitions,columns,countersorotherobstructionsshouldbetakenintoconsiderationwhenlocatingtheunit
heaterso
thataminimumquantityofairflowwillbedeflectedbysuchobstacles.
 Whenunitsarelocatedinthecentreofthespacetobeheated,theairshouldbedischargedtowardthe
exposedwalls.Inlargeareas,unitsshouldbelocatedtodischargeairalongexposedwallswithextraunits

providedtodischargeairtowardsthecentreofthearea.Foroptimumresultsheatersarebestusedin
conjunctionwithrecirculatingairfanssuspendedathighlevel.
 Atthosepointswhereinfiltrationofcoldairisexcessive,suchasentrancedoors...itisdesirabletolocatethe
unit
sothatitwilldischargedirectlytowardsthesourceofcoldair,typicallyfromadistanceof4.5mto6mor
installadownflownunitoverthedooropening.

WARNING
Iftouched,theventpipeand
internalheatersurfacesthatare
accessiblefromoutsidetheheater
willcauseburns.Suspendthe
heatersothatthesecomponents
cannotbetouched!
CAUTION
Donotlocatethe
heaterwhereitmay
beexposedtowater.


Thepresenceofchlorinevapoursinthecombustionairofgas‐firedheatingequipmentpresents
apotentialcorrosionhazardCareshouldbetakentoseparatethesevapoursfromthe
combustionprocess.
Thismaybedonebywise
locationoftheunitflueandcombustionairterminalswithregardto
exhaustersorprevailingwinddirections.
Chlorineisheavierthanair.Keepthisfactinmindwhendetermininginstallationlocationofthe
heaterinrelationtobuildingexhaustsystems.
Wherechlorinevapoursareprevalent,heaterswithspecialgrade316AISI
stainlesssteelheat
