Donotburnanyfuelotherthancoal.Neverusehighlyvolatile
substances in your stove, such as gasoline, which could
causeanexplosion.
When solid fuels are burned completely, they produce
waterandcarbondioxide.However,inlongslowburns,a
substantialamountofcarbonmonoxidemaybeproduced.
Ifallowedtobuildup,carbonmonoxide(whichisodorless)
canprovefatallypoisonous.Properventilationanddraftwill
preventthisfromhappening.Ifyousmellsmoke,thoroughly
ventilateyourdwelling,andcontactyourdealerforservice.
Re-testthedraftandproperlysetthebarometricdamper.
Othercausesofpoorventilationordraftareicing,exhaust
fans,ablockedoutsideairinlet,androomairstarvation.If
yourstoveissluggishandyougetoccasionalodor,check
thesepossibilitiesandincreasetheairowinyourhome.
4. Installing to a Prefabricated Chimney
When venting using a prefabricated chimney, be sure
to contact local building code authorities, and to follow
the manufacturer’s instructions exactly. Use only the
manufacturer’s parts; do not use makeshift installation
techniques.All prefabricated chimneys must betested to
eithertheU.S.orCanadianhigh-temperaturestandards,UL
103orULCS629.
1. Existing Masonry Chimneys
Ifyouplanonusingapre-existingmasonrychimney,have
itthoroughlyinspectedandcleaned.Anyfaultswhichmake
thechimneyunsafeandunusablemustberepairedpriorto
use.Thesecanincludeimproperheight,structuraldefects,
blockages,inadequateclearancetocombustibles,unsealed
openingsintootherroomsofthehouse,signsofcreosoteor
smokeleakage,alooseorabsentclean-outdoor,orabsence
of a liner.
2. Venting to a Masonry Chimney
Whenconnectingtoamasonrychimney,severalprovisions
arestandard.First,whetherthechimneyconnectorisvented
tothechimneythroughathimbleorabreechpipe,neither
must pass beyondthe inner surface of the chimney liner,
andbothmustbermlycementedinplacewithrefractory
cement. (A thimble is a masonry pipe which is inserted
through the chimney wall, and is frequently the preferred
method;abreechpipeisapieceofsteelpipeusedthesame
way.)InCanada,abreechpipehasridgesorprotrusionsto
lockitrmlyintotherefractorycement.Ineithercase,the
chimneyconnectorventstothechimneythroughthethimble
orbreechpipe.
Usingathimble,theconnectorslidescompletelyinsidethe
masonrytotheinneredgeoftheueliner,andmaybeeasily
removed for chimney and connector inspection.A breech
pipemustextendatleast2"(50mm)intotheroom,sothe
connectorcanbeattachedwithsheetmetalscrews.
3. Venting to a Masonry Fireplace Chimney
In some situations, a code compliant chimney originally
usedforamasonryreplacemaybeused.Inadditiontothe
requirementsfoundinthepreviousparagraphs,itisimportant
tobeawarethatallclearancesmustbemet,includingthose
fromthechimneyconnectortocombustibles.Donotforgetto
includeoorprotectioninyourplans.(SeeClearancesand
FloorProtectioninthissection.)Sincemanyreplaceshave
exposedwoodenmantelsandtrim,payspecialattentionto
theclearancesnecessarytothesematerials.
Ifyourreplacechimneyisbehindacombustiblewall,you
must use an approved wall pass-through system to gain
access to the masonry chimney. The chimney connector
must enter the chimney at a place where it is lined, and
thereplacemustbe madeinoperable.Forexample,you
mightremovethedamper,replacingitwithasecure,airtight,
noncombustible seal (removable for inspection); this also
satisestherequirementthatnoroomairmustbeallowed
toenterthechimney.
