Trouble-Shooting

STOVE DOES NOT FEED

1.No fuel in hopper.

2.Firebox draft may be too low for sensing switch in feeder circuit to operate. Check for closed doors, loose or missing gasket on doors or hopper lid.

3.Hopper lid must contact the lid position switch.

4.Feed motor will not run until the ESP control senses a certain temperature. Maybe you did not put enough fuel or starting gel in the burn pot before manually lighting the fire.

5.Restriction in the hopper or feeder. Remove all fuel and examine. Clear the obstruction.

6.Feed motor has failed.

PARTIALLY BURNED PELLETS

1.Feed rate too high.

2.Poor air to fuel mixture. (Check burn pot clean- out cover and air intake).

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 combus- tion. The circuit board has the ability to track the combustion through feed settings and ESP tem- peratures. 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 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.Fuel restrictions as noted above.

SMOKE SMELL

Seal the vent pipe joints and connection to stove with silicone. The exhaust vent is the only part of the system that is under positive pressure.

FIRE HAS GONE OUT- Check for status light.

1.No fuel in hopper.

2.Draft is too low, blocked flue.

3.Something is restricting fuel flow.

4.Hopper lid not closed properly.

5.Feed motor or combustion blower has failed.

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.

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 residue. 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.

Curing Paint

You may notice some smoke and odor during the first firing of the appliance. This is likely part of the paint curing process, and will diminish with time. Consider keeping a window open during the first hour of opera- tion, to remove any associated odors.

Keep the stove free of dust and dirt, especially around the motors and circuit board.

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 P61A is capable of burning all 3 categories of pellets, and up to a 50% mixture with shelled corn, see next page for special instructions.

It should be noted, that higher ash content will require more frequent ash removal, scraping of the burn pot, and may provide less BTU's per pound.

The moisture content of pellets must not exceed 8%, corn 15%. Higher moisture will rob BTU's and may not burn properly.

Fuel should be stored in a dry area, outside of the stove's installation clearance area and outside of the space required for charging and ash removal. See
