CanadianinstallationsmustconformtoCAN/CSA-B365.
Toventtheunitthroughthewall,connectthepipeadapter
totheexhaustmotoradapter.Iftheexhaustadapterisat
least18in.(457mm)abovegroundlevel,astraightsection
ofpelletventpipecanbeusedthroughthewall.
Your heater dealer should be able to provide you with
a kit that will handle most of this installation, which will
includeawallthimblethatwillallowtheproperclearance
throughacombustiblewall.Onceoutsidethestructure,
a3in.(76mm)clearanceshouldbemaintainedfromthe
outsidewallandacleanoutteeshouldbeplacedonthe
pipewitha90-degreeturnawayfromthehouse.Atthis
point,a3ft(0.91m)(minimum)sectionofpipeshouldbe
added with a horizontal cap, which would complete the
installation(seeFIGURE6).
A support bracket should be placed just below the
termination cap or one every 4ft (1.22m) to make the
systemmorestable.Ifyouliveinanareathathasheavy
snowfall,itisrecommendedthattheinstallationbetaller
than3ft(0.91m)togetabovethesnowdriftline.Thissame
installationcanbeusedifyourheaterisbelowgroundlevel
bysimplyaddingtheclean-outsectionandverticalpipe
insideuntilgroundlevelisreached.Withthisinstallation
youhavetobeawareofthesnowdriftline,deadgrass,and
leaves.Werecommenda3ft(0.91m)minimumvertical
riseontheinsideoroutsideofthehouse.
The“throughthewall”installationistheleastexpensiveandsimplestinstallation.Neverterminatetheendventundera

How your heater works
Yourheaterutilizesaverticalaugerfuelfeedsystemthatisoperatedbyamicroprocessorcontrolleddigitalcircuitboard.
Thedigitalcircuitboardallowstheverticalaugerfuelfeedsystemtoruninatimer-based,non-continuouscycle;this
cyclingallowstheaugertorunforapredeterminedperiodofseconds.Theaugerpushespelletsupachutelocatedin
thehopperwhichinturnfallsthroughanotherchuteintotheburnpot.Yourheaterisequippedwithanautomaticignition
systemthatshouldignitethefuelwithin3-5minutesfrompressingthe button.Aspelletsentertheburnpotand
ignite,outsideairisdrawnacrossthefuelandheatedduringthecombustionprocesswhichisthenpulledthroughtheheat
exchangerbytheexhaustmotorordraftfan.Astheheaterheatsup,roomairiscirculatedaroundtheheatexchanger
bymeansofaroomairblower,distributingwarmairintotheroom.
Theamountofheatproducedbytheheaterisproportionaltotherateofthefuelthatisburned,andthisrateiscontrolled
bytheFuelControlbutton .Inordertomaintaincombustionofthefuelatadesiredrate,theairprovidedtothe
burnchamberbytheexhaustordraftfanmustbemaintainedprecisely.Toolittleairwillresultinaamethatisnon-
energeticorlazy.Ifthefuelcontinuestoowwithtoolittleairforlongenough,theburnpotwillllwithtoomuchfueland
therewillsmotherout.Tomuchairwillresultinaamethatisoveractiveoraggressive.Theameinthissituationis
typicallyveryblueatthebottomandresemblesablowtorch.Ifthissituationcontinues,thefuelintheburnpotwillbe
consumedandtherewillgoout.
Matchingtheamountofairrequiredforpropercombustiontothefuelrateistheprimaryobjectiveineffectivelyburning
pelletsofvariousbrandsandqualitiesinyourheater.Theairtofuelratiocanbeadjustedtoallowalmostanyfuelquality
toburneffectivelybyfollowingtheproceduresdetailedintheremainderofthismanual.
Becauseaforceddraftpressureisrequiredforthecombustionprocessinsideyourheater,itisextremelyimportantthat
theexhaustsystembeproperlyinstalledandmaintained.And,thatwhenoperatingyourheater,youmakesurethat
theviewingdoorisproperlysealed.
