Trouble-Shooting
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.
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Adjuster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.
Helpful Hints
Fuel
STOVE DOES NOT FEED
1. Nofuelinhopper.
2. Fireboxdraftmaybetoolowforsensingswitchinfeeder
circuit to operate. Check for closed doors, loose or
missinggasketondoorsorhopperlid.
3. Hopperlidmustcontactthelidpositionswitch.
4. Feedmotorwillnotrununtilthe ESPcontrolsensesa
certaintemperature.Maybeyoudidnotputenoughfuel
orstartinggelintheburnpotbeforemanuallylightingthe
re.
5. Restrictioninthehopperorfeeder.Removeallfueland
examine.Cleartheobstruction.
6. Feedmotorhasfailed.
PARTIALLY BURNED PELLETS
1. Feedratetoohigh.
2. Poorairtofuelmixture.(Checkburnpotclean-outcover
andairintake).
3. Burn pot or heat exchanger tubes may need  to be
cleaned.
4. Combinationofalltheabove.
5. #6 status blink:A6blinkcontrolboardstatusindication
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)
A6blinkstatusmaybecausedbyseveralthings:
1. Blockedorpartiallyblockedue.
2. Blockedorpartiallyblockedinletair.
a. Backdraft damper on the inlet pipe may be stuck
closed.
b. If outside air is installed, the inlet cover may be

3. Theairchamberundertheburnpotmaybelledwithnes
andsmallbitsofash.
4. Theholesintheburnpotmaybegettinglledwithashor
carbonbuildup.
5. Combustionblowerfanbladesmayneedcleaned.
6. Fuelrestrictionsasnotedabove.
SMOKE SMELL
Sealtheventpipejointsandconnectiontostovewithsilicone.
Theexhaustventistheonlypartofthesystemthatisunder
positivepressure.
FIRE HAS GONE OUT- Check for status light.
1. Nofuelinhopper.
2. Draftistoolow,blockedue.
3..Somethingisrestrictingfuelow.
4. Hopperlidnotclosedproperly.
5.Feedmotororcombustionblowerhasfailed.
SMOKE IS VISIBLE COMING OUT OF VENT
1. Air-fuelratioistoorich.
a.Feedratetoohigh.
b.Drafttoolowcausedbyagasketleak.

LOW HEAT OUTPUT
1. Feedratetoolow
2. Drafttoolowbecauseofgasketleak.
3. Poorqualityordamppellets
4. Combinationof1and2.
TheAccentraisapprovedforburninganygradeofpelletized
bio-massfuel.Itisalsoapprovedforburningshelledcornin
amixturewithwoodpellets,upto50%.(SeePage46)
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%,and
cornmustnotexceed15%.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chargingandash
removal.SeePage14.
