circuit to operate. Check for closed doors, loose or
missinggasketondoorsorhopperlid.
3. FeedmotorwillnotrununtiltheESPcontrolsensesa

iscausedbypoororincompletecombustion.Thecircuit
boardhastheabilitytotrackthecombustionthroughfeed
settingsandESPtemperatures.Whenthecontrolboard
hascalculatedpoororincompletecombustion,itwillshut
downthe unitas a safety feature. (Pooror incomplete
combustionisacontributorofcreosotewhichmaycause
achimneyre)

HELPFUL HINTS
1. Cleaning Burn Pot
Wheneveryourstoveisnotburning,taketheopportunityto
scrapethe burnpot toremove carbonbuildup.A vacuum
cleanerishandytoremovetheresidue.Besurethestove
iscoldifyouuseavacuum.
Carbonbuildupcanbescrapedloosewiththereburning
usingthespecialtoolprovidedwithyourstove.Scrapethe
oorandsidesoftheburnpot.Thecarbonwillbepushedout
bytheincomingfuel.Alwayswearglovestodothis.
2. Removing Ashes
TurntheTempDialtonumber1approximately30minutes
beforeremovingashes.Thiswillresultinacoolerstoveand
ashpan.
Maximum Feed Limit settings are not needed in most
cases.Operatinginthenormalrange(#4)isrecommended
whenmaximumheatoutputisnotrequired.TheESPprobe
preventsthestovefrombeingover-red.
Keepthestovefreeofdustanddirt.
Fuel
TheP-SeriesPelletStoveisapprovedforburninganygrade
ofpelletizedbio-massfuel.
It should be noted, however, that higher ash content will
requiremorefrequentashremoval,scrapingoftheburnpot,
andmayprovidelessBTU’sperpound.
Themoisturecontentofpelletsmustnotexceed8%.Higher
moisturewillrobBTU’sandmaynotburnproperly.
Fuel should not be stored within the stove installation
clearances or within the space required for cleaning and
ashremoval.
