AND INSTALLATION INSPECTION REQUIREMENTS
IN YOUR AREA.
Beforeyoubeginaninstallation,besurethat:
• Yourstoveandchimneyconnectorwillbefarenoughfrom
combustible material to meet all clearance requirements.
• The oor protector is large enough and is constructed
properly to meet all requirements.
• Youhaveallnecessarypermitsfromlocalauthorities.
Yourlocalbuildingo󰀩cialisthenalauthorityforapproving
your installation as safe and determining that it meets local
and state codes.
The metal label permanently attached to the back of every
VermontCastings’stoveindicatesthatthestovehasbeen
tested to current UL and ULC standards, and gives the
name of the testing laboratory. Clearance and installation
information also is printed on the label. When the stove is
installed according to the information both on the label and
inthismanual,localauthoritiesusuallywillacceptthelabel
as evidence that the installation meets codes and can be
approved.
However,codesvaryindi󰀨erentareas.Beforestartingthe
installation,reviewyourplanswiththelocalbuildingauthority.
Your local dealer can provide any additional information
needed.
Foranyunresolvedinstallationissues,refertotheNational
Fire ProtectionAssociation’s publicationANSI/NFPA 211
Standard for Chimneys, Fireplaces, Vents and Solid Fuel
BurningAppliances.ForCanada,theequivalentpublication
isCSACAN-B365InstallationCodeforSolidFuelBurning
AppliancesandEquipment.Thesestandardsarethebasisfor
manynationalcodes.Theyarenationallyrecognizedandare
acceptedbymostlocalauthorities.Yourlocaldealeroryour
localbuildingo󰀩cialmayhaveacopyoftheseregulations.
IMPORTANT: Failure to follow these installation
instructions may result in a dangerous situation, including
achimneyorhousere.Followallinstructionsexactly,
and do not allow makeshift compromises to endanger
property and personal safety.
A. Outside Air
Asourceofair(oxygen)isnecessaryinorderforcombustion
to take place. Whatever combustion air is consumed by the
remustbereplaced.Airisreplacedviaairleakagearound
windowsandunderdoors.Inhomesthathavetightlysealed
doorsandwindows,anoutsideairsourceisneeded.
Items Needed for Installation (not supplied)
• Outside air adapter (available at your authorized
VermontCastingsdealer)
• Phillips head screw driver
• Silicone sealant
• 3”FlexorRigidDuct
• 3”OutsideAirTerminationCapwithScreen
• HoseClamps
• Drills and saws necessary for cutting holes through
thewallorooringinyourhome.
1. Usinga#2Phillipsscrewdriverattachtheexadapterto
theapplianceusing4screws,Figure2.17.
2. Floor&RearInstallation:Cuta3”(76mm)holeinoutside
walloroortoaccommodateoutsideairpiping.Use3”
(76mm) aluminum metal ex orrigid piping todirectly
connect outside air to appliance intake. Use a termination
capwitharodentscreen(notsupplied).Sealbetweenthe
wall(oroor)andthepipewithsiliconetopreventmoisture
penetration.
Whenpoordraftiscausedbyalowinltrationrate,openinga
groundoorwindowonthewindwardsideofthehouseand
near the stove will usually alleviate the problem.
Abettersolutionistoinstallapermanentoutsideairsupply
tothestoveand/orroom.Infact,bringingairforcombustion
from outside the home directly to the air inlet of the stove is
required for new construction in some areas.
B. Types of Chimney to Use
Youmustconnectthisappliancetoacode-approvedmasonry
chimneywithaueliner,toarelinedmasonrychimneythat

Masonry Chimneys
Aninspectionofthechimneymustconrmthatithasalining.
Do not use an unlined chimney. The chimney should have
no cracks, loose mortar, other signs of deterioration, and
blockage. Repair any defects before the chimney is used
with your stove.
Unusedopeningsinanexistingmasonrychimneymustbe
sealedwithmasonrytothethicknessofthechimneywall,
andthechimneylinershouldberepaired.Openingssealed
with pie plates or wallpaper are a hazard and should be
sealedwithmortarorrefractorycement.Intheevent of a
chimneyre,amesandsmokemaybeforcedoutofthese
unused thimbles.
The chimney should be thoroughly cleaned before use.
A newly-built masonry chimney must conform to the
standardsofyourlocalbuildingcodeor,intheabsenceofa
localcode,toarecognizednationalcode.Masonrychimneys
mustbelined,eitherwithcode-approvedmasonryorpre-cast
refractory tiles, stainless steel pipe, or a code-approved,
“poured-in-place”liner.Thechimney’sclean-outdoormust
seal tightly. A loose or leaky clean-out door can weaken
chimneydraft,causingperformanceproblems.
Prefabricated Chimneys
A prefabricated metal chimney must be one tested and
listedforusewithsolid-fuelburningappliancestotheHigh-

C. Chimney Size
Thisappliancewithan8"(203mm)uecollarisapproved
forventingintoamasonrychimneywithanominaluesize
of8"x8"(203x203mm)or8"x12"(203x305mm),and
intoarounduewithnominaluesizeof8"(203mm).This
appliancewitha6"(152mm)ueconnectorisapprovedfor
ventingintoamasonrychimneywithanominaluesizeof
8"x8"(203x203mm),andintoarounduewithnominal
ueof6"(152mm).
Whatevertheuecollarsize,thisappliancemaybevented
into larger chimneys as well. However, chimneys with
linerslargerthan8"x12"(203x305mm)mayexperience
rapidcoolingofsmokeandreductionindraft,especiallyif
the chimneys are located outside the home. These large
chimneysmayneedtobeinsulatedorhavetheiruesrelined
for proper stove performance.
Accessoriestohelpmaketheconnectionbetweenstainless
steel chimney liners and your appliance are available through
your local dealer.
D. Chimney Connector Guidelines
Achimneyconnectoristhesingle-wallpipethatconnects
the stove to the chimney. The chimney itself is the masonry
orprefabricatedstructurethatenclosestheue.Chimney
connectors are used only to connect the stove to the chimney.
Single-wall connectors should be made of 24 gauge or
heavier steel. Do not use galvanized connector; it cannot
withstand the high temperatures that can be reached by
smoke and exhaust gases, and may release toxic fumes
underhighheat.Theconnectormaybe6"(152mm)or8"
(203mm)indiameter.
Ifpossible, donot pass thechimney connectorthrough a
combustiblewallorceiling.Ifpassagethroughacombustible
wall is unavoidable, refer to the section on Wall Pass-
Throughs.Donotpasstheconnectorthroughanattic,acloset
or similar concealed space. The whole connector should be
exposedandaccessibleforinspectionandcleaning.

Securing the Single-wall Connector to a Prefabricated
Chimney
Follow the installation instructions of the chimney manufacturer
exactlyasyouinstallthechimney.Themanufacturerofthe
chimneywillsupplytheaccessoriestosupportthechimney,
eitherfromtheroofofthehouse,attheceilingoftheroom
wherethestoveisinstalled,orfromanexteriorwall.
Special adapters are available from your local dealer to
make the connection between the prefabricated chimney and
the chimney connector. The top of such adapters attaches
directly to the chimney or to the chimney’s ceiling support
package,whilethebottomoftheadapterisscrewedtothe
chimney connector.
Theseadaptersaredesignedsothetopendwilltoutside
theinnerwallofthechimney,andthebottomendwilltinside
therstsectionofchimneyconnector.
Securing the Single-wall Connector to a Masonry
Chimney
Bothfreestandingmasonrychimneysandreplacemasonry
chimneys may be used for your installation.
Freestanding Installations
Ifthechimneyconnectormustpassthroughacombustible
walltoreachthechimney,followtherecommendationsin
the Wall Pass-Through section that follows. The opening
through the chimney wall to the ue (the “breech”) must
belinedwitheitheraceramicormetalcylinder,calledthe
“thimble,”whichiscementedsecurelyinplace.Mostchimney

Floor protection requirements also apply to fireplace
installations.Refertothe"FloorProtection"sectioninthis
manual.
Wall Pass-Throughs
Wheneverpossible,designyourinstallationsotheconnector
does not pass through a combustible wall. If you are
consideringawallpass-throughinyourinstallation,check
withyourbuildinginspectorbeforeyoubegin.Also,check
with the chimney connector manufacturer for any specic
requirements.
Accessoriesareavailableforuseaswallpass-throughs.If
usingoneofthese,makesureithasbeentestedandlisted
foruseasawallpass-through.
Toinstallathimblesleeve,slideitintothebreechuntilitis
ushwiththeinneruewall.Donotextenditintotheactual
uepassage,asthiscouldinterferewiththedraft.
Thethimblesleeveshouldprotrude1-2"(25-50mm)intothe
room. Use furnace cement and thin gasketing to seal the
sleeve in place in the thimble. Secure the chimney connector
to the outer end of the sleeve with sheet metal screws.
Withoutathimble,asuitablelengthofchimneyconnector
canbeextendedthroughthebreechtotheinnerfaceofthe
ueliner,andcementedsecurelyinplace.Additionalpieces
of connector are then attached with sheet metal screws.
E. Fireplace Installations
The chimney connector may be connected to the chimney
abovethereplaceopeningorthroughthereplace.
Above the Fireplace
Your appliance may be connected to a chimney above a
replaceopening,Figure2.6.Insuchinstallations,thestove
ispositionedonthehearthinfrontofthereplaceandthe
chimney connector rises from the stove top and then angles
ninety degrees back into the chimney. The chimney liner
shouldextendtothepointatwhichthechimneyconnector
enters the chimney.
If the chimney connector in your installation enters the
chimneyaboveareplace,followalltheguidelinesmentioned
aboveforfreestandinginstallations.Inaddition,givespecial
consideration to the following points:
• Check the clearance between the mantel and the
chimney connector, and any combustible trim or the
mantel.
• Checktheclearancebetweenthechimneyconnectorand
theceiling.Theclearanceshouldbeatleast30"(762
mm)withunshieldedconnectors.Consulttheclearance
charts for other installation options.
Aspecialpiececalledthe“thimblesleeve,”slightlysmaller
in diameter than standard connectors and most thimbles,
will facilitate the removal of the chimney connector system
forinspectionandcleaning,Figure2.5.Thimblesleevesare

DO NOT CONNECT THIS APPLIANCE TO ANY AIR
DISTRIBUTION DUCT OR SYSTEM.
ThreeothermethodsarealsoapprovedbytheNFPA:
• Placing a section of chimney connector inside a ventilated
thimble,whichinturnisseparatedfromcombustiblesby
6"(152mm)ofberglassinsulatingmaterial.
• Placing a section of chimney connector inside a section
of 9" (230 mm) diameter, solid-insulated, factory-built
chimney, with 2" (51 mm) of air space between the
chimney section and combustibles.
• Using a section of solid-insulated double-wall high
temperaturechimney,withaninsidediameterthesameas
thechimneyconnector,atleastoneinchofsolidinsulation,
andaminimumof9"(229mm)airspacebetweenthe
outer wall of the chimney section and combustibles.
In Canada, The Canadian Standards Association has
establisheddi󰀨erentguidelinesforwallpass-throughs.Figure
2.9showsonemethod,inwhichallcombustiblematerialin
thewalliscutawaytoprovidetherequired18"(457mm)
clearance for the connector. The resulting space must remain
empty.Aush-mountedsheetmetalcovermaybeusedon
onesideonly.Ifcoversmustbeusedonbothsides,each
cover must be mounted on noncombustible spacers at least
1"(25mm)clearofthewall.
IntheUnitedStates,theNationalFireProtectionAssociation
(NFPA) has established guidelines for passing chimney
connectors through combustible walls. Many building
code inspectors follow these guidelines when approving
installations.
Figure 2.8 shows one NFPA recommended method.All
combustible material in the wall is cut away from the
single-wallconnectortoprovidetherequired12"(305mm)
clearance.Anymaterialusedtocloseuptheopeningmust
be noncombustible.

F. Floor Protection
Atremendousamountofheatradiatesfromthebottomplate
ofyourstove.Theoorareadirectlyunderandaroundthe
stove will require protection from radiant heat as well as from
straysparksorembersthatmayescapetherebox.
HeatprotectionisprovidedwiththeuseoftheBottomHeat
Shield supplied with the stove.
Most installations will require the bottom heat shield to be
attached. Only when the stove is placed on a completely
noncombustible surface such as unpainted concrete over
earth may it be used without the heat shield.
With the bottom heat shield installed this appliance was
tested with spark and ember protection only. There is no
required"R"value,andtheoorprotectoronlyneedstobe
anon-combustiblematerial,e.g.ceramictileorsheetmetal.
Important:Allinstallationsonacombustibleoorrequire
the use of the supplied bottom heat shield.
TheEncoredoesnotrequireRvalueoorprotection.
Theminimumoorprotectormaterialis20gaugesheetmetal.
OtheroorprotectormaterialsthatcanbeusedincludeType
Ihearthpads,ceramictile,stone,brick,etc.
Protection requirements vary somewhat between the Untied
StatesandCanadaasfollows:
In U. S. installationstheoorprotectorisrequiredunderthe
stoveandmustextendatleast16"(notincludingtheashlip)
fromthefrontofthestove(“F,”Figure2.10),andatleast6"
fromthesidesandrear.(“D”and“E,”Figure2.10)
In rear venting congurations, oor protection must also
extendunderthechimneyconnectorand2"toeitherside.
(“C,” Figure 2.10) For the 8" (203 mm) connector, the
protectormustbeaminimumof12"(305mm)wide.Forthe
6"(152mm)connector,theprotectormustbe10"(254mm)
wide. The protector must be centered under the connector.
Tomeettheserequirements,aoorprotectormustbeatleast
39" wide and 45" deep.
In Canada:A noncombustible oor protector is required
underthestoveaswell.Theoorprotectormustextend18"

Keep the Stove a Safe Distance From Surrounding
Materials
Both a stove and its chimney connector radiate heat in all
directionswhenoperating,andnearbycombustiblematerials
can overheat dangerously if they are too close to the heat
source.Asafeinstallationrequiresthatadequateclearance
be maintained between the hot stove and its connector and
nearby combustibles.
Clearance is the distance between either your stove or
chimney connector, and nearby walls, oors, the ceiling,
andanyotherxedcombustiblesurface.Thisappliancehas
specicclearancerequirementsthathavebeenestablished
after careful research and testing. These clearance
requirements must be strictly observed.
Inaddition,keepfurnishingsandothercombustiblematerials
away from the stove. In general, a distance of 48" (1219
mm)mustbemaintainedbetweenthestoveandmovable
combustible items such as drying clothes, furniture,
newspapers,rewood,etc.Keepingthoseclearanceareas
empty assures that nearby surfaces and objects will not
overheat.
Safe Ways to Reduce Clearances
Clearance requirements are established to meet every
installationpossibility,andtheyinvolvethecombinationof
these variables:
• When the stove pipe has no listed heat shield mounted
on it.
• When the wall has no heat shield mounted on it.
• When the wall has a heat shield mounted on it.
• When the wall and stove pipe have heat shields.
Ingeneral,thegreatestclearanceisrequiredwhenyouplace
a stove and its connector near a wall with no heat shield.
For example, when this appliance is installed using 6"
connector pipe parallel to the rear wall and no connector
shieldis used,it mustbe atleast 10"(254 mm)from the
wallbehinditandatleast19"(483mm)fromwallsoneither
side. These dimensions are measured from the back of the
rear shroud and the side edge of the cast iron top to the
combustible wall.
Ifthisapplianceisinstalledinacornerandnoshieldisused,
thecornersofthestovetopmustbeatleast18-1/2"(470
mm)fromnearbywalls.
Clearancesmaybereducedonlybymeansapprovedbythe
regulatoryauthority,andinaccordancewiththeclearances
listedinthismanual.Refertotheclearancechartforapproved
clearancereductionspecications.
NOTE: Installation of this appliance is not permitted in
alcoves.

Areplaceinstallationrequiresspecialclearancebetween
thesideofthestoveandtherightandleftwalls,betweenthe
sideofthestoveandthedecorativesidetrimonthereplace

Wall Shields
One way to reduce clearances is with a wall shield
constructedof24gaugeorheaviersheetmetal,orofanother
noncombustible material such as 1/2" (13 mm) insulation
board such as Durock®or Wonderboard®,orcommonbrick
“laidonat,”withthe3-1/2"(90mm)sidedown.
Shields must be spaced out from the combustible surface 1"
(25mm)onnoncombustiblespacers,asinFigure2.11.The
spacers should not be directly behind the stove or chimney
connector.
Airmustbeabletoowbetweenthewallandtheshield.At
least50%ofthebottom1"(25mm)oftheshieldmustbe
open,andtheshieldmustbeopenatthetop.Metalscreening
across the top will keep small stray objects from being trapped
behindtheshield,Figure2.11.
