1. No fuel in hopper.
2. Firebox draft may be too low for sensing switch in
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 combus-
tion. The circuit board has the ability to track the
combustion through feed settings and ESP tempera-
tures. 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 prevents the stove from being over-
red.
Keep the stove free of dust and dirt.

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 P68 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 content
will require more frequent ash removal, scraping of
the burn pot, 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 P68.
The moisture content of pellets must not exceed 8%.
Corn should be 15% or less. Higher moisture will rob
BTU's and may not burn properly.
Pellet fuel should  be stored within the stove
installation clearances or within the space required for
charging and ash removal. See Page 7.
