PP38+ Pellet Stove
1. Air-fuel ratio is too rich.
A. Feed rate too high.
B. Draft too low caused by a gasket leak.
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.
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 control prevents the stove from
being over-red.
Keep the stove free of dust and dirt.
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 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.
1. No fuel in hopper.
2. Draft is too low, blocked ue.
3. Something is restricting fuel ow.
4. Hopper lid not closed properly.
5. Feed motor or combustion blower has failed.
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 PP38+ 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,
and when mixing with corn, 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 PP38+.
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.
