Chimney
Thisappliancemustnotbefittedintoachimneyservinganotherheatingappliance.Itismost
importantthatthereisnoobstructionintheflueorchimney.Pleaseensurethatanyexisting
chimneyisclearofobstructionandsweptcleanimmediatelybeforeinstallationofthe
stove.Ifthe
chimneyhasbeenusedforanopenfireitisrecommendedthatitbesweptforagainafteryouhave
usedtheapplianceforamonth.Asaclosedapplianceoperatesatahigherfluetemperature,itis
possiblefordepositsthathadpreviouslyadheredtobe
dislodgedwiththeconsequentriskofflue
blockage.
Afluedraughtofminimum1.5mm(14.71Pascal’s)toamaximum2.5mm(24.52Pascal’s)water
gaugeisrequiredforsatisfactoryapplianceperformance.Aproperlybuiltmasonryorfactory
constructedchimney,preferablywithaheightof5metresormore,shouldensureaconsistent

draught(draw)underavarietyofweatherconditions.Thefluedraughtshouldbecheckedunderfire
athighoutputandifitexceedstherecommendedmaximum,adraughtstabilisermustbefittedso
thattherateofburningcanbecontrolledandtopreventoverfiring(see5below).If
youhaveany
doubtsaboutthesuitabilityofyourchimney,consultyourlocaldealer/stockist.
Theoutletfromthechimneyshouldbeabovetheroofofthebuildinginaccordancewiththe
provisionsofBuildingRegulationsApprovedDocumentJ.
Ifinstallationisintoanexistingchimneythenitmustbesoundand
havenocracksorotherfaults
whichmightallowfumesintothehouse.Olderproperties,especially,mayhavechimneyfaultsor
thecrosssectionmaybetoolargei.e.morethan230mmx230mm.Remedialactionshouldbe
takenifrequiredandseekingexpertadviceifnecessary.If
itisfoundnecessarytolinethechimney
thenafluelinersuitableforsolidfuelmustbeusedinaccordancewithBuildingRegulations
ApprovedDocumentJ.
IfthereisnoexistingchimneytheneitheraprefabricatedblockchimneyinaccordancewithBuilding
RegulationsApprovedDocumentJoratwinwalled
insulatedstainlesssteelfluetoBS4543canbe
used.Thesechimneysmustbefittedinaccordancewiththemanufacturer’sinstructionsand
BuildingRegulations.
Thelinerdiametermustnotbelessthan6”.Ifthedrawonthechimneyisexcessive,afluedraught
stabiliserwillhelptoslowthis
down.Anexcessivedrawmaycauseoverfiringandthuscausethe
internalcomponentsofthestovetowearoutquicker.
Anybendinthechimneyorconnectingfluepipeshouldnotexceed45°.90°bendsshouldnotbe
used.Adequateprovisione.g.easilyaccessiblesootdoorordoorsmust
beprovidedforsweeping
thechimneyandconnectingfluepipe.
