4 4 Chimneys & Venting
A. Venting & Draft Management
A stove is part of a system, which includes the chimney,
the operator, the fuel, and the home. The other parts of the
systemwillaecthowwellthestoveworks.Whenthereis
agoodmatchbetweenalltheparts,thesystemworkswell.
Wood stove or insert operation depends on natural
(unforced)draft.Naturaldraft occurs when theexhaustis
hotter(andthereforelighter)thantheoutdoorairatthetop
ofthechimney.Thebiggerthetemperaturedierence,the
stronger the draft. As the hot gases rise through the chimney
they provide suction or ‘draw’ that pulls air into the stove for
combustion.Aslow,lazyrewiththestove’sairinletsfully
openindicatesaweakdraft.Abriskre,supportedonlybyair
entering the stove through the normal inlets, indicates a good
draft. The stove’s air inlets are passive; they regulate how
much air can enter the stove, but they don’t move air into it.
Depending on the features of your installation - steel or
masonry chimney, inside or outside the house, matched to
thestove’soutletoroversized-yoursystemmaywarmup
quickly,oritmaytakeawhiletowarmupandoperatewell.
With an ‘airtight’ stove, one which restricts the amount of air
gettingintotherebox,thechimneymustkeepthestove’s
exhaust warm all the way to the outdoors in order for the
stovetoworkwell.Somechimneysdothisbetterthanothers.
Here’salistoffeaturesandtheireects.
Note:ElbowandTee’sreducethedraftofachimneysystem.
Designtheinstallationtominimizechangesindirection.No
more than 2 tee’s or elbows may be used.
Masonry Chimney
Masonry is a traditional material for chimneys, but it can
perform poorly when it serves an ‘airtight’ stove. Masonry
isaveryeective‘heatsink’-itabsorbsalotofheat.Itcan
cool the chimney gases enough to diminish draft. The bigger
thechimney,thelongerittakestowarmup.It’softenvery
diculttowarmupanoutdoormasonrychimney,especially
anoversizedone,andkeepitwarmenoughtomaintainan
adequate draft.
Steel Chimney
Mostfactory-madesteelchimneyshavealayerofinsulation
around the inner ue. This insulation keeps the chimney
warm. The insulation is less dense than masonry, so a steel
chimneywarmsupmorequicklythanamasonrychimney.
Steeldoesn’thavethegoodlooksofmasonry,butitperforms
much better.
Indoor/Outdoor Location
Becausethechimneymustkeepthesmokewarm,it’sbestto
locate it inside the house. This uses the house as insulation
fortheueandallowssomeheatreleaseintothehome.An
indoorchimneywon’tloseitsheattotheoutdoors,soittakes
lessheatfromthestovetoheatitupandkeepitwarm.
Single Venting
Each‘airtight’stoverequiresitsownue.Ifanairtightstove
is vented to a ue that also serves an open replace, or
aleakierstove, it’seasierfor the chimneydrafttopull air
in through those channels and performance of the stove
suers.Imagineavacuumcleanerwithaholeinthehoseto
understandtheeecthere.Insomecasestheotherappliance
can even cause a negative draft through the stove, and result
in a dangerous draft reversal.
Draft
TheVermontCastingsAspenC3requiresaminimumdraftof
10 Pa or .04” of W.C. Draft too low can cause low heat output
and a sluggish burn. Draft higher than 30 Pa or .12 of W.C.
canresultinshortburntimesandoverring.Ensurethedraft
of the chimney is in correct range for operating the Aspen C3.
Flue Sizing
The inside size of a chimney for an ‘airtight’ stove should
matchthesizeofthestove’sueoutlet.Whenachimney
serves an airtight stove, more is not better; in fact, it can be a
disadvantage.Hotgasesloseheatfasterastheytravelslower
throughachimney;ifweventastovewithasix-inchuecollar
(28squareincharea)intoa10x10"ue,thegasesslowto
one third their original speed. This allows the gases to cool
morerapids,whichweakensdraftstrength.Ifanoversizedue
is also outside the house, the heat it absorbs gets transferred
totheoutdoorairandtheueusuallystayscool.
Itiscommonforamasonryue,especiallyoneservinga
replace,tobeoversizedforthestove.Itcantakequiteawhile
towarmupsuchaue,andtheresultscanbedisappointing.
Thebestsolutiontoanoversizedueisaninsulatedsteel
chimneyliner,thesamediameterasthestoveorinsertsue
outlet;thelinerkeepstheexhaustwarm,andtheresultisa
strongerdraft.Annon-insulatedlinerisasecondchoice-the
linerkeepstheexhaustrestrictedtoitsoriginalsize,butthe
hot gases still must warm up the air around the liner. This
makesthewarm-upprocesstakelonger.
Pipe & Chimney Layout
Everyturntheexhaustmusttakeasittravelstothechimney
top will slow it down. The ideal pipe and chimney layout is to
vent vertically into a completely straight and vertical chimney.
Ifyouarestartingfromscratch,usethislayoutifpossible.
Ifthestovepipemustelbowtoenterachimney,locatethe
thimble about midway between the stove top and the ceiling.
This achieves several goals: it allows the gases to speed up
before they must turn, it leaves some pipe in the room for
heattransfer,anditgivesyoulong-termexibilityforinstalling
adierentstovewithoutrelocatingthethimble.
Thereshouldbenomorethaneightfeetofsingle-wallstove
pipe between the stove and a chimney; longer runs can cool
the exhaust enough to cause draft and creosote problems.
With prefabricated chimney, bring it down to six to eight feet
from the stove. With a masonry chimney, arrange the pipe
so that it turns into the chimney within eight feet of the stove.
