WARNING
 Thefluemustbeinaccordancewithallinternationalandnationalrulesandregulationsin
force.Localrequirementsmayapplyinadditiontonationalrequirements.
 Failuretoprovideproperflueingcouldresultindeath,seriousinjuryand/orproperty
damage.
 Theproductsofcombustionmustbefluedtooutside
atmosphere.Commonflues(formore
thanoneappliance)mustnotbeused.
 Singlewallfluepipeexposedtocoldairorrunthroughunheatedareasshouldbeinsulated
toavoidcondensation.
 Ifthefluepassesthroughacombustibleelementofthebuildingitmustbeenclosedbya
sleeveofnon‐combustiblematerialandseparatedfromthesleevebyatleasta25mmair
break.Thetemperatureofanycombustiblematerialneartothefluemustnotexceed65°C
whentheheaterisinoperation.Thefluemustbeatleast50mmawayfromany
combustiblematerial.
 Provision
mustbemadeforcondensationtoflowfreelytoapointtowhichitcanbe
released,i.e.drain.


ModelULSA/ULSAECheatersmaybeinstalledastypeBortypeCinstallations.Theunitheatersaredesignedto
operatesafelyandefficientlywitheitherahorizontalorverticalfluesystemwheninstalledaccordingtothe
specificrequirementsandinstructions.Ifthisheaterisreplacinganexistingheater,besure
thattheflueisofthe
correctsizeandthattheexistingflueisingoodcondition.Acorrectlysizedfluesystemisrequiredforsafe
operationoftheheater.Animpropersizedfluesystemcancauseunsafeconditionsand/orcreatecondensation.
Theunitsmaybeinstalledasabalanced
fluetypeCheaterrequiringbothacombustionairinletpipeandaflue
pipeorasapowerventedheatertypeBwherethecombustionairistakenfromthespacewhereheateris
installedandwhichrequiresonlyafluepipeexhaustingtooutdoors.Allproductsofcombustionmust
befluedto
outdooratmosphere.
EachheaterinstalledasatypeBappliancemustbefittedwithanindividualfluepipeandthecombustionairinlet
openingmustbeprovidedwithaprotectiongrill.
EachheaterinstalledasatypeCappliancemustbefittedwithanindividualcombustionair/flue
pipesystem.Type
C2appliance,withsinglepipesystemforsupplyofcombustionairandevacuationoffluegasses,arenotallowed.
Fortesting,thefluepipeshouldincludeasealabletestpoint.Ideallythetestpointshouldbeatleast450mmaway
fromtheairheaterflueconnection socket.However
ifaconcentricflueisattacheddirectlytotheconnection
socketsthenthecombustionshouldbetestedthroughtheflueoutletcollarviaadrilledtestpointwhichmustbe
securelypluggedoncompletion.
Followthefluepipemanufacturer’sinstallationinstructionsformakingjoints,includingconnectionstotheair
heater,
forpassingthroughabuildingelementandforsupportrequirements.

installed
onthetoppanelbutcaneasilybereplacedon
therearpanelifrequired.Incaseofchange,a
separatekitmustbeorderedatthesupplier.
