Trouble-Shooting 33
FEEDER DOES NOT FEED
1.No pellets in hopper.
2.Firebox draft may be too low for low draft pres- sure switch in feeder circuit to operate. Check for open doors, loose or missing gasket on doors or hopper lid, faulty pressure switch.
3.Feed motor will not run until ESP
senses 165 deg. F. Maybe you did not put enough pellets in the burn pot before lighting the fire.
4.Something is restricting flow 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 com- bustion. 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 combus- tion it will shut down the unit as a safety feature. (Poor or incomplete combustion is a contributer of creasote 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 be stuck closed.
b.if outside air is installed the inlet cover may be blocked.
3.The air chamber under the burnpot may be filled with fines and small bits of ash.
4.The holes in the burnpot may be getting filled with ash or carbon buildup.
5.Combustion blower fan blades may need cleaned.
6.Combustion intake assembly not properly latched.
7.No fuel in hopper
SMOKE SMELL
Seal the vent pipe joints and connection to frame with silicone.
FIRE HAS GONE OUT
1.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 VENT
1.
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.
Helpful Hints
Cleaning Burn Pot
Whenever your stove is not burning, take the op- portunity to scrape the burn pot to remove carbon buildup. 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 fire burning using the special tool provided with your stove. Scrape the floor 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 re- quired. The ESP probe prevents the stove from being
Keep the stove 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 Accentra 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 con- tent 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 Accentra.
The moisture content must not exceed 8%. Higher moisture will rob BTU's and may not burn properly.
