ThestoveisdesignedandapprovedinaccordancewithEN13240andNS3058for
stokingsplit,driedfirewood.Thefirewoodmusthaveawatercontentof1522%andits
max.lengthshouldbethelengthofthecombustionchamberminus5060mm.
Stokingwithwetfirewoodcausesbothsoot,environmentalpollutionandbadfuel
economy.Freshlycutwoodcontainsapprox.5070%waterandisthoroug hlyunsuitable
forstoking.Allowatleast1yearofstoragetimefornewlycutwoodbeforeusing.Wood
withadiameterofmorethan100mmshouldbesplit.Regardlessofwoodsize,itshould
alwayshaveatleastonesurfaceareafreeofbark.
Wedonotrecommendstoki ngwithpainted,laminatedorimpregnatedwood,woodwith
asyntheticsurface,paintedrefusewood,chipboard,pl ywood,domesticwaste,paper
briquettesandpitcoal,asthiswillproducemalodoroussmoke,whichcouldbe
poisonous.
Whenfiringwiththeabovementioneditemsandamountslargerthanthose
recommended,thestoveissubjectedtoalargeramountofheat,whi chresultsina
higherchimneytemperatureandlowerefficiency.Thiscanresultinthestoveand
chimneybecomingdamagedandwouldvoidthewarranty.
Thecalorificvalueofthefirewoodiscloselyconnectedtothemoisturelevel.
Moistfirewoodhasalowheatvalue.Themorewaterthewoodcontains,themore
energyittakesforthiswatertovaporise,resultinginthisenergybeinglost.
