FEEDER DOES NOT FEED
1. Nofuelinhopper.
2. Fireboxdraftmaybetoolowforlowdraftpressureswitch
in feeder circuit to operate. Check for closed doors,
loose or missing gasket on doors or hopper lid, faulty
pressureswitch.
3. FeedmotorwillnotrununtilESPsenses200
°
F.Maybe
youdidnotputenoughfuelintheburnpotbeforelighting
there.
4. Somethingisrestrictingowinthehopperorcausingthe
slideplatetostick.
5. Feedmotorhasfailed.
PARTIALLY BURNED FUEL
1. Feedratetoohigh.
2. Drafttoolow.
3. Burnpot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TerminationCapmaybe

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. Thereisnofuelinthehopper.
COMBUSTION BLOWER RUNS AFTER SHUT DOWN
Thisisanormalfunction.Thecombustionblowerwillrun
for5hoursafterthestoveiscompletelycool.
SMOKE SMELL
Seal the vent pipe joints and connection to stove with
silicone.

1. Air-fuelratioistoorich.
a. Feedratetoohigh.
b. Drafttoolowcausedbyagasketleak.
2. Unitisinanignitioncycle.
Troubleshooting
LOW HEAT OUTPUT
1. Feedratetoolow
2. Temperaturesettingtoolow(StoveTempMode)
3. Drafttoolowbecauseofgasketleak.

Helpful Hints
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
sides of the burnpot (corn grate), and the oor and sides
(pelletgrate).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(#2corn)(#4pellet)is
recommendedwhenmaximumheatoutputisnotrequired.
TheESPpreventsthestovefrombeingover-red.
Keepthestovefreeofdustanddirt.
Fuel
ThePC45canburncornwithmoisturelevelsupto16%,
with14.5%orlessbeingideal.
Pelletfuelsareputinto3categoriesintermsofashcontent.
Premiumat1%orless,Standardat3%orlessandallothers
at3%ormore.
ThePC45iscapableofburningall3categoriesofpellets
duetoapatentedfeederandburnpotsystem.
It should be noted, however, that higher ash content will
require more frequent ash removal and may provide less
BTU'sperpound.Normally,standardandhighashpellets
cost less than premium pellets and can be cost effective
whenburnedinthePC45.
Themoisturecontentofpelletsmustnotexceed8%.Higher
moisturewillrobBTU'sandmaynotburnproperly.
ThePC45iscapableofburninggrainsotherthancorn,such
aswheat,oatsorbarley.Grainsvarywidelyfromareatoarea,
aswillstoveperformance.Whenburninggrainsotherthan
corn,itmaybenecessarytomakechangestothesettings
onthecircuitboardforoptimumperformance.Contactyour
HarmanDealerforinstructions.
