feeder circuit to operate. ,

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 re.

5. Restriction in the hopper or feeder. Remove all fuel

and examine. Clear the obstruction.

6. Feed motor has failed.

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.   : A 6 blink control board status

indication is caused by poor or incomplete combustion.

The 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 blades may need cleaned.

6. Fuel restrictions as noted above.

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.

Whenever your stove is not burning, take the

opportunity to scrape the burn pot to remove carbon

buildup. A vacuum cleaner is handy to remove the

residue.          



Carbon buildup can be scraped loose with the re

burning using the special tool provided with your stove.

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.



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

required. The ESP probe prevents the stove from being

over-red.

Keep the stove free of dust and dirt.

See page 3 for detailed fuel information.

Wood Pellet size is regulated at .23" to .35" in diameter

with a maximum length of 1.5" long.

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 XXV is capable of burning all 3 categories of

pellets or a mixture of up to 50% shelled corn and

pellets.

It should be noted, fuels with higher ash content will

require more frequent; ash removal, scraping of the burn

pot, increased cleaning frequency and may provide less

BTU's per pound.

The moisture content of pellets must not exceed 8%,

and Corn 15%. Higher moisture will rob BTU's and may

not burn properly.

Fuel should be stored within the stove installation

clearances or within the space required for charging and

ash removal. See Page 7.
