33FEEDER DOES NOT FEED1. No pellets in hopper.2. Firebox draft may be too low for low draft pres-sure switch in feeder circuit to operate. Check foropen doors, loose or missing gasket on doors orhopper lid, faulty pressure switch.3. Feed motor will not run until ESPsenses 165 deg. F. Maybe you did not putenough pellets in the burn pot before lighting thefire.4. Something is restricting flow in the hopper orcausing the slide plate to stick.5. Feed motor has failed.PARTIALLY BURNED PELLETS1. Feed rate too high.2. Draft too low. (Check burn pot clean out slideand door gasket).3. Burn pot or heat exchanger tubes may need tobe cleaned.4. Combination of all the above.5. #6 status blink: A 6 blink control board statusindication is caused by poor or incomplete com-bustion. The Automatic Ignition circuit board hasthe ability to track the combustion through feedsettings and ESP temperatures. When the controlboard has calculated poor or incomplete combus-tion it will shut down the unit as a safety feature.(Poor or incomplete combustion is a contributer ofcreasote which may cause a chimney fire)A 6 blink status may be caused by several things:1. Blocked or partially blocked flue.2. Blocked or partially blocked inlet air.a. backdraft damper on the inlet pipe may bestuck closed.b. if outside air is installed the inlet cover may beblocked.3. The air chamber under the burnpot may be filledwith fines and small bits of ash.4. The holes in the burnpot may be getting filledwith ash or carbon buildup.5. Combus tion blower f an blades may needcleaned.6. Combus tion intake assembly not properlylatched.7. No fuel in hopperSMOKE SMELLSeal the vent pipe joints and connection to framewith silicone.FIRE HAS GONE OUT1. No pellets in hopper.2. Draft setting is too low.3. Something is restricting fuel flow.4. Feed motor or draft motor has failed.5. Power failure or blown fuse.SMOKE IS VISIBLE COMING OUT OF VENT1. Air-fuel ratio is too rich.A. Feed rate too high.B. Draft too low caused by a gasket leak.LOW HEAT OUTPUT1. Feed rate too low2. Draft too low because of gasket leak.3. Poor quality or damp pellets4. Combination of 1. and 2.Trouble-ShootingCleaning Burn PotWhenever your stove is not burning, take the op-portunity to scrape the burn pot to remove carbonbuildup. A vacuum cleaner is handy to remove the resi-due. Be sure the stove is cold if you use a vacuum.Carbon buildup can be scraped loose with the fireburning using the special tool provided with your stove.Scrape the floor and sides of the burn pot. The carbonwill be pushed out by the incoming fuel. Always weargloves to do this.Removing AshesTurn the Temp Dial to number 1 approximately 30minutes before removing ashes. This will result in acooler stove and ash pan.Maximum Feed Adjuster settings are not neededin most cases. Operating in the normal range (#4) isrecommended when maximum heat output is not re-quired. The ESP probe prevents the stove from beingover-fired.Keep the stove free of dust and dirt.Helpful HintsFuelPellet fuels are put into 3 categories in terms ofash content. Premium at 1% or less, Standard at 3% orless and all others at 3% or more.The Accentra is capable of burning all 3 categoriesof pellets due to a patented feeder and burn pot system.It should be noted, however, that higher ash con-tent will require more frequent ash removal and mayprovide less BTU's per pound. Normally, standard andhigh ash pellets cost less than premium pellets and canbe cost effective when burned in the Accentra.The moisture content must not exceed 8%. Highermoisture will rob BTU's and may not burn properly.
