2.2GENERAL



Theinstructionsinthismanualapplytothecondensinggas‐firedairheatermodelULSA/ULSAEC.Allmodels

andsizesareavailableforusewitheithernatural,propaneorbutanegaswithinoperatingtemperatures

between‐15°Cand40°C.

Theseheatersaredesignedforuseindomestic,industrialandcommercialpremises,suitableonlyforindoor

installation

Thetypeofgas,theinputrateandtheelectricalsupplyrequirementsareshownontheheaterratingplate.

Theinstructionsareonlyvalidforthecountryofuseindicatedontheappliance.Ifnotcorrectcontactyour

supplier.

Installationshouldbedonebyasuitablyqualifiedinstallerinaccordancewiththeseinstructionsandwithall

rulesinforce.

Theinstallationmanualisshippedwiththeheater.Verifythattheliteratureiscorrectfortheheaterbeing

installed.Ifthemanualisincorrectfortheheater,contactthesupplierbeforebeginninginstallation.

Ensuretheenvironmentinwhichtheairheaterwillbeinstalledwillnotcreateahazardi.e.whereexcessive

dust,flammableorcorrosivesubstancesand/orvapoursandcombustiblematerialsmaybepresent.



2.3WARRANTY



Warrantyisvoidif:



Heatersareusedinatmospherescontainingflammablevapoursoratmospherescontaining

chlorinatedorhalogenatedhydrocarbonsoranycontaminant(silicone,aluminiumoxide,etc...).

Theinstallationisnotinaccordancewiththeseinstructions.

Wiringisnotinaccordancewiththediagramfurnishedwiththeheater.

Unitisinstalledwithoutproperclearancetocombustiblematerialsorwithoutproperventilation

andairforcombustion.

Airthroughputisnotadjustedwithintherangespecifiedontheratingplate.



2.4UNCRATING&PREPARATION



Theunitwastestoperatedandinspectedatthefactorypriortocratingandwasinproperoperatingcondition.

Iftheheaterhasincurreddamageinshipment,documentthedamagewiththetransportcompanyand

contactyoursupplier.Beforeinstallationcheckthattheapplianceasdescribedonthepackaginglabelisin

accordancewiththecorrecttypeandmodelasspecifiedonthedataplateandcomplieswithyourcustomer

order.Afterunpackingtheappliance,leaveitfastenedtoanybasepackingfortransportationuntilithasbeen

suspendedoruntiljustbeforebasemounting.Thisaffordsprotectiontotheunderside.

Checktheratingplatetodetermineiftheheaterisappropriatefortheintendedinstallation.

Readthemanualthoroughlyandbecomefamiliarwiththeinstallationrequirementsofyourheater.Ifyoudo

nothaveknowledgeoflocalrequirements,checkwiththegassupplierandanyotherlocalagenciesthatmight

haverequirementsconcerningthisinstallation.

Beforebeginningmakepreparationsfornecessarysupplies,toolsandmanpower.Iftheinstallationincludes

optionalparts,installtheseoptionsbeforetheheaterissuspended.Followtheinstructionsincludedinthe

optionpackage.



1701ULSA(EC)--EN, p. 5/30

2.5HEATERLOCATION



AttentionFluerequirementsmayaffectlocation.Consultsection 7before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.
