VENTING REQUIREMENTS
• INSTALLVENTATCLEARANCESSPECIFIEDBYTHEVENTMANUFACTURER.
• DONOTCONNECTTHEPELLETVENTTOAVENTSERVINGANYOTHERAPPLIANCEORSTOVE.
• DONOTINSTALLAFLUEDAMPERINTHEEXHAUSTVENTINGSYSTEMOFTHISUNIT.
Thefollowinginstallationguidelinesmustbefollowedtoensureconformitywithboththesafetylistingofthisstove
andtolocalbuildingcodes.Donotusemakeshiftmethodsorcompromiseintheinstallation.
MAXIMUM VENTING DISTANCE
InstallationMUSTincludeatleast3-feetofverticalpipeoutsidethehome.Thiswillcreatesomenaturaldraftto
reducethepossibilityofsmokeorodorduringapplianceshutdownandkeepexhaustfromcausinganuisance
orhazardbyexposingpeopleorshrubstohightemperatures.Themaximumrecommendverticalventingheight
is12-feetfor3-inchtype“PL”vent.Totallengthofhorizontalventmustnotexceed4-feet.Thiscouldcauseback
pressure.Usenomorethan180degreesofelbows(two90-degreeelbows,ortwo45-degreeandone90-degree
elbow,etc.)tomaintainadequatedraft.
IMPORTANCE OF PROPER DRAFT
Draftistheforcewhichmovesairfromtheapplianceupthroughthechimney.Theamountofdraftinyour
chimneydependsonthelengthofthechimney,localgeography,nearbyobstructionsandotherfactors.Too
muchdraftmaycauseexcessivetemperaturesintheappliance.Inadequatedraftmaycausebackpufnginto
theroomand‘plugging’ofthechimney.
Inadequate draft will cause the appliance to leak smoke into the room through appliance and chimney
connectorjoints.
Anuncontrollableburnorexcessivetemperatureindicatesexcessivedraft.
Takeintoaccountthechimney’slocationtoinsureitisnottooclosetoneighborsorinavalleywhichmaycause
unhealthyornuisanceconditions.
PELLET VENT TYPE
AULlisted3-inchor4-inchtype“PL”pelletventexhaustsystemmustbeusedforinstallationandattachedtothe
pipeconnectorprovidedonthebackofthestove(usea3-inchto4-inchadapterfor4-inchpipe).Connection
atbackofstovemustbesealedusingHi-TempRTV.Use4-inchventiftheventheightisover12-feetorifthe
installationisover2,500feetabovesealevel.
WerecommendtheuseofSimpsonDura-Vent®orMetal-Fab®pipe(ifyouuseotherpipe,consultyourlocal
buildingcodesand/orbuildinginspectors).DonotuseType-BGasVentpipeorgalvanizedpipewiththisunit.The
pelletventpipeisdesignedtodisassembleforcleaningandshouldbecheckedseveraltimesduringtheburning
season.Pelletventpipeisnotfurnishedwiththeunitandmustbepurchasedseparately.
PELLET VENT INSTALLATION
Theinstallationmustincludeaclean-outteetoenablecollectionofyashandtopermitperiodiccleaningofthe
exhaustsystem.90-degreeelbowsaccumulateyashandsoottherebyreducingexhaustowandperformance
ofthestove.Eachelboworteereducesdraftpotentialby30%to50%.
Alljointsintheventsystemmustbefastenedbyatleast3screws,andalljointsmustbesealedwithHi-Temp
RTVsiliconesealanttobeairtight.Theareawheretheventpipepenetratestotheexteriorofthehomemustbe
sealedwithsiliconeorothermeanstomaintainthevaporbarrierbetweentheexteriorandtheinteriorofthe
home.
Ventsurfacescangethotenoughtocauseburnsiftouchedbychildren.Noncombustibleshieldingorguards
mayberequired.
PELLET VENT TERMINATION
Donotterminatetheventinanenclosedorsemi-enclosedarea,suchas;carport,garage,attic,crawlspace,
underasundeckorporch,narrowwalkway,oranyotherlocationthatcanbuildupaconcentrationoffumes.
Theterminationmustexhaustabovetheoutsideairinletelevation.Theterminationmustnotbelocatedwhereit
willbecomepluggedbysnoworothermaterials.Donotterminatetheventingintoanexistingsteelormasonry
chimney.
IMPORTANT!Thisunitisequippedwithanegativedraftsystemthatpullsairthroughtheburnpotandpushes
theexhaustoutofthedwelling.Ifthisunitisconnectedtoauesystemotherthanthewayexplainedinthis
manual,itwillnotfunctionproperly.

THROUGH THE WALL INSTALLATION (RECOMMENDED INSTALLATION)
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7).
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deck,inanalcove,underawindow,orbetweentwowindows.WerecommendSimpsonDura-Vent®
orMetal-Fab®kits.
THROUGH THE ROOF/CEILING INSTALLATION
Whenventingtheheaterthroughtheceiling,thepipeisconnectedthesameasthroughthewall,exceptthe
clean-outteeisalwaysontheinsideofthehouse,anda3in.(76mm)adapterisaddedbeforetheclean-outtee.
Youmustusetheproperceilingsupportangesandroofashing(suppliedbythepipemanufacturer;followthe
pipemanufacturer’sdirections).Itisimportanttonotethatifyourverticalrunofpipeismorethan15ft(4.57m),
thepelletventpipesizeshouldbeincreasedto4in.(102mm)indiameter.
Donotexceedmorethan4ft(1.22m)ofpipeonahorizontalrunanduseasfewelbowsaspossible.Ifanoffset
isrequired,itisbettertoinstall45-degreeelbowsratherthan90-degreeelbows.

HOW YOUR STOVE WORKS
Yourpelletstoveutilizesainclinedaugerfuelfeedsystemthatisoperatedbyamicroprocessorcontrolleddigital
circuitboard.Thedigitalcircuitboardallowstheinclined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atthefront/bottomofthehopperwhichinturnfallsthroughanotherchuteintothe
burnpot.Yourstoveisequippedwithanautomaticignitionsystemthatshouldignitethefuelwithin5-10minutes
frompressingtheONbutton.Aspelletsentertheburnpot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stove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stoveisproportionaltotherateofthefuelthatisburned,andthisrate
iscontrolledbythe“HEATRANGE”setting.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stove.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stove,itisextremelyimportant
thattheexhaustsystembeproperlyinstalledandmaintained.And,thatwhenoperatingyourstove,youmake
surethattheviewingdoorisproperlysealed.

Ifachimneyorcreosotereoccurs,pressthe“OFF”buttonimmediately.Donotunplugtheunit.
DAILY OPERATION
• Thehopperandstovetopwillbehotduringoperation;therefore,youshouldalwaysusesometypeofhand
protectionwhenrefuelingyourstove.
• Neverplaceyourhandneartheaugerwhilethestoveisinoperation.
Thisunitshouldbelledwhenthehopperleveldropsbelow3-inches.
Intheeventofapoweroutage,thestovewillnotfunction.Itisveryimportantthatunitbeventedproperly(with
outsideair),asthenaturaldraftisneededtoclearthesmokefromthestoveduringapoweroutage.Iftheunit
was“ON”whenthepoweroutageoccurred,oneofthefollowingwilltakeplace:
1. Ifthestoveisstillwarm,itwillresumefeedingfuelandcontinuetooperatenormally.Iftherehasgoneout,
youwillhavetopressthe“OFF”buttonandthenthe“ON”buttonagaintobeginanewstart-upsequence.
2. Ifthestovehascooled-off,itwillresettoits“OFF”condition.Atthispoint,youmaypressthe“ON”buttonand
theunitwillbeginanewstart-upsequence.
NOTE:Theunitwillalsoshutdownintheeventofanexhaustblowerfailure;ifthisisthecase,theunitwillnotre-
startandyoumustcontactCustomerServiceat(800)750-2723.
SAFETY AND CONVENIENCE FEATURES
Yourpelletstoveincorporatesasafetypressureswitchthathelpsensurethateverythingisinproperworking
orderbeforefeedingfueltotheburnpot.Becausethestoveworksusinganinduceddraftpressure,thestove
willnotcontinuetooperateiftheviewingdoorisleftopen;oriftheexhaustblowerfailsortheexhaustsystemis
blocked.
Thetemperaturelimitcontrol(Thermistor)willpreventyourstovefromoperatingatabnormallyhightemperatures.
Should the stove temperature begin to approach the factory pre-set limit, the temperature limit control will
automaticallyslowdowntheaugerfeedrateuntilthetemperaturereturnstoanormalcondition.Eventhough
theheaterwilloperateonthehighestsetting,werecommendtooperateyourheateronthissettingforonlya
shortperiodoftime.(1houretc.)
Yourpelletstovealsoincludesanauto-startigniterasastandardfeature.Theuseofotherrestartermaterials
(woodchips,startergel,etc.)isnotnecessary.Bysimplypressingthe“ON”buttononthedigitalcontrolpanel,
yourstovewillbegintofeedfuelandautomaticallystartwithin5minutes.

CreosoteFormation–Whenanywoodisburnedslowly,itproducestarandotherorganicvapors,whichcombine
withexpelledmoisturetoformcreosote.Thecreosotevaporscondenseintherelativelycoolchimneyueora
newlystartedreorfromaslow-burningre.Asaresult,creosoteresidueaccumulatesontheuelining.When
ignited,thiscreosotemakesanextremelyhotre,whichmaydamagethechimneyorevendestroythehouse.
Despitetheirhighefciency,pelletstovescanaccumulatecreosoteundercertainconditions.
FlyAsh–Thisaccumulatesinthehorizontalportionofanexhaustrun.Thoughnon-combustible,itmayimpede
thenormalexhaustow.Itshouldthereforebeperiodicallyremoved.
InspectionandRemoval–Thechimneyconnectorandchimneyshouldbeinspectedannuallyorpertonto
determineifacreosoteoryashbuild-uphasoccurred.Ifcreosotehasaccumulated,itshouldberemovedto
reducetheriskofachimneyre.Inspectthesystematthestoveconnectionandatthechimneytop.Cooler
surfacestendtobuildcreosotedepositsquicker,soitisimportanttocheckthechimneyfromthetopaswellas
fromthebottom.Thecreosoteshouldberemovedwithabrushspecicallydesignedforthetypeofchimney
inuse.Aqualiedchimneysweepcanperformthisservice.Itisalsorecommendedthatbeforeeachheating
seasontheentiresystembeprofessionallyinspected,cleanedand,ifnecessary,repaired.Tocleanthechimney,
disconnecttheventfromthestove.
INTERIOR CHAMBERS
Periodicallyremoveandcleantheburnpotandtheareainsidetheburnpothousing.Inparticularitisadvisable
tocleanouttheholesintheburnpottoremoveanybuildupthatmaypreventairfrommovingthroughtheburn
potfreely.Removethetwo(2)platesoneachsideoftheburnpothousingandcleanoutthatrearchamber.
Ifavacuumisusedtocleanyourstove,wesuggestusingavacuumdesignedforashremoval.Someregular
vacuumcleaner(i.e.shopvacs)mayleakashintotheroom.
ASH DISPOSAL
Disposalof ashes – Ashesshouldbe placed in asteelcontainer with a tight ttinglid and moved outdoors
immediately.Theclosedcontainerofashesshouldbeplacedonanoncombustibleoororontheground,well
awayfromcombustiblematerials,pendingnaldisposal.Iftheashesaredisposedofbyburialinsoilorotherwise
locallydispersed,theyshouldberetainedintheclosedcontaineruntilallcindershavethoroughlycooled.Other
wasteshallnotbeplacedinthiscontainer.
SMOKE AND CO MONITORS
Burningwoodnaturallyproducessmokeandcarbonmonoxide(CO)emissions.COisapoisonousgaswhen
exposed to elevated concentrations for extended periods of time. While the modern combustion systems in
heatersdrasticallyreducetheamountofCOemittedoutthechimney,exposuretothegasesinclosedorconned
areascanbedangerous.Makesureyoustovegasketsandchimneyjointsareingoodworkingorderandsealing
properlytoensureunintendedexposure.ItisrecommendedthatyouusebothsmokeandCOmonitorsinareas
havingthepotentialtogenerateCO.
Maintenance
CAUTION:Thiswoodheaterneedsperiodicinspectionandrepairforproperoperation.Itisagainstfederal
regulationstooperatethiswoodheaterinamannerinconsistentwithoperatinginstructionsinthismanual.
