FEEDER DOES NOT FEED
1. Nopelletsinhopper.
2. Fireboxdraftmaybetoolowforlowdraftpressureswitch
infeedercircuittooperate.Check for improperly closed
doors,looseormissinggasketondoorsorhopperlid,or
afaultypressureswitch.
3. FeedmotorwillnotrununtiltheESPsenses170deg.
F.Maybeyoudidnotputenoughpelletsintheburnpot
beforelightingtheremanually.
4. Somethingisrestrictingowinthehopperorcausingthe
slideplatetostick.
5. Feedmotorhasfailed.
PARTIALLY BURNED PELLETS
1. Feedratetoohigh.
2. Drafttoolow.(Checkburnpotclean-outslideanddoor
gasket).
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
AutomaticIgnition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blocked.
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mayneedcleaned.
6. Thereisnofuelinthehopper.
SMOKE SMELL
Sealtheventpipejointsandconnectiontounitwithsilicone.
FIRE HAS GONE OUT
1. Nopelletsinhopper.
2. Draftsettingistoolow.
3. Somethingisrestrictingfuelow.
4. Feedmotororcombustionblowerhasfailed.
5. Powerfailureorblownfuse.
6. Fireboxdoororhopperleftopen.
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.
Cleaning Burn Pot
Wheneveryourboiler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 of no hot
embers if you use a vacuum.
Carbonbuildupcanbescrapedloosewiththereburning
usingthespecialtoolprovidedwithyourboiler.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
Ashescanbe removed whileinoperation,but extracare
mustbetakenandalwaysweargloves.
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
preventsthestovefrombeingover-red.
Keeptheboilerfreeofdustanddirt.
Fuel
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HF60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,scrapingoftheburnpot,
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HF60.
Themoisturecontentmustnotexceed8%.Highermoisture
willrobBTU’sandmaynotburnproperly.
