P68 Pellet Stove
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
manuallylightingthere.
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
causeachimneyre)
A 6 blink status may be caused by several
things:
1.Blockedorpartiallyblockedue.
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.Theairchamberundertheburnpotmaybelled

4.Theholesintheburnpotmaybegettinglled
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.Draftistoolow,blockedue.
3.Somethingisrestrictingfuelow.
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.
P68 Trouble-Shooting
Cleaning Burn Pot
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. Be sure the stove is cold if you use a
vacuum.
Carbon buildup can be scraped loose with the
reburningusingthespecialtoolprovidedwithyour
stove.Scrapetheoorandsidesoftheburnpot.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
required. The ESP prevents the stove from being
over-red.
Keep the stove free of dust and dirt.
Helpful Hints
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 P68 is capable of burning all 3 categories
of pellets due to a patented feeder and burn pot sys-
tem.
It should be noted, however, that higher ash
content will require more frequent ash removal, scrap-
ing 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 not be stored within the stove
installation clearances or within the space required for
charging and ash removal. See Page 6.
