FEEDER DOES NOT FEED1. No pellets in hopper.2. Firebox draft may be too low for low draft pressureswitch in feeder circuit to operate. Check for closeddoors, loose or missing gasket on doors or hopper 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 the fire.4. Something is restricting flow in the hopper or caus-ing 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 slide anddoor gasket).3. Burn pot or heat exchanger tubes may need to becleaned.4. Combination of all the above.5. #6 status blink: A 6 blink control board status indi-cation is caused by poor or incomplete combustion.The Advance Automatic Ignition circuit board has theability to track the combustion through feed settingsand ESP temperatures. When the control board hascalculated poor or incomplete combustion it will shutdown the unit as a safety feature. (Poor or incompletecombustion is a contributer of creasote which maycause 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 be stuckclosed.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 filled withash or carbon buildup.5. Combustion blower fan blades may need cleaned.6. Combustion intake assembly not properly latched.SMOKE SMELLSeal the vent pipe joints and connection to stove withsilicone.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 oppor-tunity to scrape the burn pot to remove carbon buildup. Avacuum cleaner is handy to remove the residue. Be sure thestove 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 carbon willbe pushed out by the incoming fuel. Always wear gloves todo this.Removing AshesTurn the Temp Dial to number 1 approximately 30minutes before removing ashes. This will result in a coolerstove and ash pan.Maximum Feed Adjuster settings are not needed inmost cases. Operating in the normal range (#4) is recom-mended when maximum heat output is not required. TheESP probe prevents the stove from being over-fired.Keep the stove free of dust and dirt.Helpful HintsFuelPellet fuels are put into 3 categories in terms of ashcontent. Premium at 1% or less, Standard at 3% or less andall others at 3% or more.The Accentra is capable of burning all 3 categories ofpellets due to a patented feeder and burn pot system.It should be noted, however, that higher ash contentwill require more frequent ash removal and may provideless BTU's per pound. Normally, standard and high ash pel-lets cost less than premium pellets and can be cost effectivewhen burned in the Advance.The moisture content must not exceed 8%. Highermoisture will rob BTU's and may not burn properly.
