Trouble-Shooting - Harman Stove Company P61-2 Owner's Manual

FEEDER DOES NOT FEED
1. No pellets in hopper.
2. 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.
3. Feed motor has failed.
4. Something is restricting flow in the hopper
or causing the slide plate to stick.
5. Firebox draft may be too low for low draft
pressure switch in feeder circuit to operate.
Check for closed doors, loose or missing gas-
ket on doors or hopper lid, faulty pressure
switch.
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.
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
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.
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 P61 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 and may
provide less BTU's per lb. Normally, standard and high ash pellets cost less than premium pellets and can
be cost effective when burned in the P61.
The moisture content must not exceed 8%. Higher moisture will rob BTU's and may not burn properly.

Trouble-Shooting

FIRE HAS GONE OUT
1. No pellets in hopper.
2. Feed rate too low.
3. Something is restricting fuel flow.
4. Feed motor or draft motor has failed.
5. Power failure or blown fuse.
SMOKE IS VISIBLE COMING OUT OF VENT
1. Air-fuel ratio is too rich.
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
Removing Ashes
Turn the Stove Temp Dial to number 1 approxi-
mately 30 minutes before removing ashes. This will
result in a cooler stove and ash pan.
Maximum Turbo settings are not needed in
most cases. Operating in the normal range is rec-
ommended when maximum heat output is not re-
quired. The ESP probe prevents the stove from be-
ing over-fired.
Keep the stove free of dust and dirt.
