Thestovesareequippedwithcooldoorhandles  aRaisspecialfeature whichmeans
youcouldalmostdoawaywithgloves.Beaware,however,thatallexteriorsurfaces
becomehotduringuse  sotakeextremecare.
Convection
Raisstovesareconvectionstoves.Thismeansthatthestove’sbackandsidepanelsare
notoverheated.Convectionmeansthatthereisacirculationofair,whichensuresthat
theheatisdistributedmoreevenlythroughouttheentireroom.Thecoldairissuckedinat
thebaseofthestoveandupthroughtheconvectionchannel,whichrunsalongthe
stove’scombustionchamber.Theheatedaircomesoutatthetopofthestove,which
ensuresacirculationofwarmairthroughouttheroom.
Chimney
Inorderforthestovetoperformsatisfactorilythechimneyheightmustbesufficientto
ensureanadequatedraughtofapproximately15Pasoastocleartheproductsof
combustionandpreventsmokeproblemsintotheroom.
NOTE:Achimneyheightofnotlessthan4.5metresmeasuredverticallyfromtheoutletof
thestovetothetopofthechimneyshouldbesatisfactory.Alternativelythecalculation
proceduregiveninEN133841maybeusedasthebasisfordecidingwhethera
particularchimneydesignwillprovidesufficientdraught.
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l argei.e.morethan230mmx230
mm.Remedialactionshouldbetaken,ifrequired,seeki ng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.
Anyexistingchimneymustbeclearofobstructionandhavebeenswe ptclean
immediatelybeforeinstallationofthestove.Ifthestoveisfittedinplaceofanopenfire
thenthechimneyshouldbesweptonemonthafterinstallationtoclearanysootfalls
whichmayhaveoccurredduetothedifferenceincombustionbetweenthestoveandthe
openfire.
Ifthereisnoexistingchimneythenanynewsystemmustbetothedesignation
describedaboveandinaccordancewithBuildingRegulationsApprovedDocumentJ.
Asinglewallmetalfluepipeissuitableforconnectingthestovetothec himneybutisnot
suitableforuseasthecompletechimney.Thechimneyandconnectingfluepipemust
haveaminimumdiameterof150mmanditsdimensionshouldbenotlessthanthesize
oftheoutletsocketofthestove.
