thestovemaybefacilitatedbytheinstallationofablower.

The wood stove must not be hooked up to a hot air distribution system since an excessive

accumulation of heat may occur.

A wood stove must never be installed in a hallway or near a staircase, since it may block the

Thestovepipemustbemadeofaluminizedorcoldrollsteelwithaminimumthicknessof0.021”or

0.53mm.Itisstrictlyforbiddentousegalvanizedsteel.

Yoursmokepipeshouldbeassembledinsuchawaythatthemalesection(crimpedend)ofthepipe

facesdown.Attacheachofthesectionstooneanotherwiththreeequidistantmetalscrews.

Thepipemustbeshortandstraight.Allsectionsinstalledhorizontallymustslopeatleast1/4inch

Association)andrequestthelatesteditionoftheNFPAStandard211.

Toinsureagooddraft,thetotallengthofthecouplingpipeshouldneverexceed8’to10’(24to3.04

CHIMNEY

Yourwoodstovemaybehookedupwitha6”factorybuiltormasonrychimney.Ifyouareusinga

factorybuiltchimney,itmustcomplywithUL103standard;thereforeitmustbeaTypeHT(2100°F).

Itisextremelyimportantthatitbeinstalledaccordingtothemanufacturer’sspecications.

Ifyouareusingamasonrychimney,itisimportantthatitbebuiltincompliancewiththespecica-

tionsoftheNationalBuildingCode.Itmustbelinedwithreclaybricks,metalorclaytilessealed

togetherwithrecement.(Rounduesarethemostefcient).

Theinteriordiameterofthechimneyuemustbeidenticaltothestovesmokeexhaust.Auewhich

istoosmallmaycausedraftproblems,whilealargeuefavoursrapidcoolingofthegas,andhence

thebuild-upofcreosoteandtheriskofchimneyres.Notethatitisthechimneyandnotthestove

whichcreatesthedrafteffect;yourstove’sperformanceisdirectlydependentonanadequatedraft

fromyourchimney.

The following recommendations may be useful for the installation of your chimney:

1. DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.

2. It must rise above the roof at least 3’ (0.9 mm) from the uppermost point of contact.

3. The chimney must exceed any part of the building or other obstruction within a 10’ (3.04m)

distance by a height of 2’ (0.6 m).

4. Installation of an interior chimney is always preferable to an exterior chimney. Indeed, the

interior chimney will, by denition, be hotter than an exterior chimney, being heated up

by the ambient air in the house. Therefore the gas which circulates will cool more slowly,

thus reducing the build-up of creosote and the risk of chimney res.

5. The draft caused by the tendency for hot air to rise will be increased with an interior chim-

ney.

6. Using a re screen at the extremity of the chimney requires regular inspection in order

to insure that it is not obstructed thus blocking the draft, and it should be cleaned when

regularly.

It is EXTREMELY IMPORTANT that you use DRY WOOD only in your wood stove.Thewoodshouldhavedried

for9to15months,suchthatthehumiditycontent(inweight)isreducedbelow20%oftheweightofthelog.Itisvery

importanttokeepinmindthatevenifthewoodhasbeencutforone,twoorevenmoreyears,itisnotnecessarilydry,if

ithasbeenstoredinpoorconditions.Underextremeconditionsitmayrotinsteadofdrying.Thispointcannotbeover

stressed;thevastmajorityoftheproblemsrelatedtotheoperationofawoodstoveiscausedbythefactthatthewood

usedwastoodamporhaddriedinpoorconditions.Theseproblemscanbe:

-ignitionproblems

-creosotebuild-upcausingchimneyres

-lowenergyyield

-blackenedwindows

-incompletelogcombustion

Smallerpiecesofwoodwilldryfaster.Alllogsexceeding6”indiametershouldbesplit.Thewoodshouldnotbestored

directlyontheground.Airshouldcirculatethroughthecord.A24”to48”airspaceshouldbeleftbetweeneachrowof

logs,whichshouldbeplacedinthesunniestlocationpossible.Theupperlayerofwoodshouldbeprotectedfromthe

elementbutnotthesides.

TESTING YOUR WOOD

Whenthestoveisthoroughlywarmed,placeonepieceofsplitwood(aboutveinchesindiameter)paralleltothedoor

onthebedofredembers.

Keeptheaircontrolfullopenbypullingonitandclosethedoor.Ifignitionofthepieceisaccomplishedwithin90seconds

fromthetimeifwasplacedinthestove,yourwoodiscorrectlydried.Ifignitiontakeslonger,yourwoodisdamp.

Ifyourwoodhissesandwaterorvaporescapesattheendsofthepiece,yourwoodissoakedorfreshlycut.Donotuse

thiswoodinyourstove.Largeamountsofcreosotecouldbedepositedinyourchimney,creatingpotentialconditions

forachimneyre.

THE FIRST FIRES

Thefreshpaintonyourstoveneedstobecuredtopreserveitsquality.Oncethefuelchargeisproperlyignited,only

burnsmallresinyourstovefortherstfourhoursofoperation.Neveropentheaircontrolmorethannecessaryto

achieveamediumburnrate.

Makesurethatthere’senoughaircirculationwhilecuringthestove.Theodorscouldbesmelledduringthe3or4rst

res.Neverstartyourstoveoutside.Youwillnotbeabletoseeifyouareoverheating.

IGNITION

Aftermakingsurethatthestoveairintakecontrolsarefullyopen(completelypull-outtowardsyou),placeseveralrumpled

sheetsofpaperinthecentreofthecombustionchamber.Place8to10piecesofsmalldrykindlingwoodoverthepaper

intheformofatent.Youmayalsoplaceafewpiecesofheatingwood,butchoosethesmallerones.Nochemicalproduct

shouldbeusedtolightthere.

Beforeignitingthepaperandkindlingwood,itisrecommendedthatyouwarmupthechimney.Thisisdoneinorderto

avoidbackdraftproblemsoftenduetonegativepressureinthehouse.Ifsuchisthecase,openawindowslightlynear

thestoveandtwisttogetherafewsheetsofnewspaperintoatorch.Lightupthispapertorchandholditascloseas

isinitiated,youarereadytoignitethestovebylightingthepaperandkindlingwoodinsidethecombustionchamber.

Whenyouhaveachievedagoodbedofhotembers,werecommendthefollowingburnprocedures:

HEATING

Controlledcombustionisthemostefcienttechniqueforwoodheatingbecauseitenablesyoutoselectthetypeof

combustionyouwantforeachgivensituation.Thewoodwillburnslowlyifthewoodstoveairintakecontrolisadjusted

toreducetheoxygensupplyinthecombustionchambertoaminimum.Ontheotherhand,woodwillburnquicklyif

theaircontrolisadjustedtoadmitalargerquantityofoxygeninthecombustionchamber.Theairintakecontrolon

yourstoveisverysimple.Ifyoupullonitoutcompletelytowardsyou,itisfullyopen.Ifyoupushonituntilitstopsthe

combustionairisreducedtoaminimum.Realoperatingconditionsmaygiveverydifferentresultsthanthoseobtained

For optimal operation of your wood stove, we recommend you to operate it with a wood load

approximatelyequivalenttotheheightofrebricks.

Itisimportanttonotethatwoodcombustionconsumesambientoxygenintheroom.Inthecaseof

We strongly recommend that you install a magnetic thermometer on your smoke exhaust pipe,

approximately 18” above the stove. This thermometer will indicate the temperature of your gas

TO PREVENT CREOSOTE BUILD UP

• Alwaysburndrywood.Thisallowscleanburnsandhigherchimneytemperatures,thereforeless
