P68 Pellet Stove
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
closed doors
, loose or missing gasket on doors
or hopper lid, or a 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 manually.
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
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. Co mbus tio n blower f an bla des may ne ed
cleaned.
6. There is no fuel in the hopper.
SMOKE SMELL
Seal the vent pipe joints and connection to stove
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 combustion blower has failed.
5. Power failure or blown fuse.
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 car-
bon 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.
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-fired.
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 con-
tent 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 must not exceed 8%.
Higher moisture will rob BTU's and may not burn
properly.
