SAFETY NOTICE: IF YOUR DEFIANT®IS NOT PROPERLY
INSTALLED, A HOUSE FIRE MAY RESULT. TO REDUCE
THE RISK OF FIRE, FOLLOW THE INSTALLATION
INSTRUCTIONS. CONTACT LOCAL BUILDING OR FIRE
OFFICIALSABOUT RESTRICTIONSAND 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of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differentareas.Beforestartingthe
installation,reviewyourplanswiththelocalbuildingauthor-
ity. 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ofcialmayhaveacopyoftheseregulations.
IMPORTANT: Failure to follow these installation instruc-
tions 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.

Outside Air
In some modern, super-insulated homes, there may be
inadequateairsupplyforcombustionbecauseofinsufcient
airinltrationintothebuilding.Suchairentersahomethrough
unsealed cracks and openings. Exhaust fans in kitchens or
bathrooms can compete with the stove for available air and
compound the problem.
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.
Pressure variations within the house do not affect a stove
equipped with an outside air supply, and improved stove
performanceoftenresults.AnOutsideAirKitfortheDeant®
is available from your local dealer.
Chimney Height
Altitudeaffectschimneyperformance.Whenusingan8"oval
to6"uecollaradapterontheDeant®,refertoFigure1for
suggested chimney heights at various altitudes. Chimney
heightshouldbemeasuredfromtheuecollartothetopof
the chimney. The recommended minimum chimney height
is16’(5m).

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.

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.
Inhorizontalrunsofunshieldedchimneyconnector,maintain
adistanceof30"(762mm)fromtheceiling.Keepitasshort
and direct as possible, with no more than two 90° turns.
Slope horizontal runs of connector upward 1/4" per foot
(6mmpermeter)goingfromthestovetowardthechimney.
Therecommendedmaximumlengthofahorizontalrunis3’
(1m),andthetotallengthshouldbenolongerthan8’(2.4
m).Incathedralceilinginstallations,extendtheprefabricated
chimneydownwardtowithin8’(2.4m)ofthestove.Thiswill
helpmaintainagooddraftbykeepingthesmokewarm,so
that it rises readily.
Wearglovesandprotectiveeyewearwhendrilling,cuttingor
joiningsectionsofchimneyconnector.
Single-wall Chimney Connectors
• Begin assembly at the
uecollarofthestove.
Inserttherstcrimped
endintothestove’sue
collar, and keep each
crimped end pointing
toward the stove.
(Figure 5) Using the
holes in the ue collar
as guides, drill 1/8" (3
mm) holes in the bottom
of the first section of
chimney connector and
secure it to the flue

griddleopeningandthefrontoftheuecollartoprotect
thenishwhenyoudrillthefronthole.
• Fasteneachjointbetweensectionsofchimneyconnector,
includingtelescopingjoints,withatleastthree(3)sheet
metal screws. The pre-drilled holes in the top of each
section of chimney connector serve as guides when you
drill1/8"(3mm)holesinthebottomofthenextsection.

• Fastenthechimneyconnectortothechimney.Instructions
for various installations follow. Figure 6 illustrates the
general layout of chimney connector parts.
• Be sure the installed stove and chimney connector are
correct distances from nearby combustible materials.
NOTE: Special slip pipes and thimble sleeves that form
telescopingjointsbetween sections of chimneyconnector
are available to simplify installations. They often eliminate
the need to cut individual connector sections. Consult your
local dealer about these special pieces.
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

Fireplace Installations
The chimney connector may be connected to the chimney
abovethereplaceopeningorthroughthereplace.
Above the Fireplace
The Deant®may be connected to a chimney above a
replaceopening.(Figure8)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 stove 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.
• Thereplacedampermustbesealedtopreventroomair
fromescapinguptheue.However,itmustbepossible
to re-open the damper to inspect or clean the chimney.
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.
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 7) Thimble sleeves are
available from your local dealer.

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

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 different guidelines for wall pass-throughs. Figure
11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

cover must be mounted on noncombustible spacers at least
1"(25mm)clearofthewall.
Figure 10 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.
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

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.
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.

Floor Protection
Atremendousamountofheatradiatesfromthebottomplate
ofyourstove.Theoorareadirectlyunderandaroundthe

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

How to Determine if Alternate Floor Protection Materials
are Acceptable
Alloorprotectionmustbenoncombustible(i.e.metals,brick,
stone,mineralberboards,etc.).Anyorganicmaterials(i.e.
plastics, wood paper products, etc.) are combustible and
must not be used. The oor protection specied includes
some form of thermal designation such as R-value (thermal
resistance) or k-factor (thermal conductivity).
Procedure:
1.ConvertspecicationstoR-value:
i. R-value given - no conversion needed.
ii. k-factor is given with a required thickness (T) in inches:
iii.K-factorisgivenwitharequiredthickness(T)ininches:
iv. r-factor is given with a required thickness (T) in inches:
R = r x T
2. Determine the R-value of the proposed alternate oor
protector:
i. Use the formula in Step 1 to convert values not
expressed as R.
ii.  For multiple layers, add R-values of each layer to
determine overall R-value.
3. IftheoverallR-valueofthesystemisgreaterthanthe
R-valueofthe specied oor protector,thealternateis
acceptable.
EXAMPLE:Thespeciedoorprotectorshouldbe1/2-inch
thickmaterialwithk-factorof0.84.Theproposedalternate
is4"brickwithanr-factorof0.2over1/8"mineralboardwith
ak-factorof0.29
Stepa:UseformulaabovetoconvertspecicationtoR-value:
Step b: Calculate R of proposed system.
 4"brickofr=0.2,therefore:
Rbrick=0.2x4=0.8
 1/8"mineralboardofk=0.29,therefore
Rmineralboard=x0.125=0.431
Rtotal = Rbrick + Rmineralboard=0.8+0.431=1.231
Stepc:CompareproposedsystemRtotalof1.231tospecied
Rof0.59.SinceproposedsystemRtotalisgreaterthan
required,thesystemisacceptable.

Floor Protection for Fireplace Installation
Do not assume that your replace hearth is completely
noncombustible.Manyreplacehearthsdonotsatisfythe
"completelynoncombustible"requirementbecausethebrick
orconcreteinfrontofthereplaceopeningissupportedby
heavy wood framing. Because heat passes readily through
brickorconcrete,itcaneasilypassthroughtothewood.
Asaresult,suchreplacehearthscanbearehazardand
areconsideredacombustibleoor.
For all replace installations, follow the oor protection
guidelines described above, including the need for a
bottomshield.Keepinmindthatmanyraisedhearthswill
extend less than the required clearance from the front of
the heater. In such cases, sufcient oor protection as
described above must be added in front of the hearth to
satisfytheminimumoorprotectorrequirementfromthe
frontofthestove:16"(410mm)intheUnitedStatesand
18"(460mm)inCanada.Hearthrugsdonotsatisfythe
requirementforoorprotectionastheyarenotreproof.
Fireplace installations also have special clearance
requirementsto the sidewalls,sidedecorativetrimand
replacemantel.Refertotheinformationonreplaceand
mantel trim shields in this section.
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.TheDeant®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, firewood, etc. Keeping those
clearance areas empty assures that nearby surfaces and
objectswillnotoverheat.

Fireplace and Mantel Trim Shields
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

Noncombustible shields
installed 1" (25 mm) away from
the combustible surface on
noncombustible spacers, called
ventilatedshields, may beused
to reduce clearances.
To protect a mantel from the
heat of a stove in a fireplace
installation,use a custom-made
ventilated mantel shield that is
at least 48" (1220 mm) long,
centered over the stove. (Figure
14) Ventilated shields for side
trim must extend the full length
of the trim.
Anunprotectedmantel("A",Figure15)cannotbemorethan
9"(230mm)deepandmusthaveaminimumclearanceof
41"(1041mm),measuredfromthestove’stopplate.With
aventilatedshield,thisclearancemaybereducedsafelyto

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theDeant®is installed parallel to the rear
wallandnoconnectorshieldisused,itmustbeatleast15"
(381mm)fromthewallbehinditandatleast21"(533mm)
from walls on either side. These dimensions are measured
from the top edge of the stove to the combustible wall.
IftheDeant®isinstalledinacornerandnoshieldisused,
thecornersofthestovetopmustbeatleast5"(127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Page14forapprovedclearance
reductionspecications.
NOTE:Aminimumceilingheightof8’(2.4m)isrequiredfor
allinstallationsoftheDeant®.
NOTE: Installation of the Deant®is not permitted in
alcoves.
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31⁄2"(90mm)sidedown.
Shieldsmustbespacedoutfromthecombustiblesurface1"
(25mm)onnoncombustiblespacers,asinFigure13.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13)
Theshieldmustbeaminimumof48"(1219mm)tall,and
mustextendatleast19"(483mm)higherthanthetopofthe
stove,whicheverishigher.Theshieldbehindthechimney
connectormustbe30"(760mm)wide,centeredbehindthe
pipe; for installations that use an approved prefabricated
chimneytopassthroughtheceiling,theshieldbehindthe
chimneyconnectormuststop1"(25mm)belowtheceiling.
With8"connectionsandchimneys,becauseofpotentially
higher pipe temperatures, the shield must extend the full
height of the wall (up to 9’ (2.7 m)) and stop 1" (25 mm)
