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.
HELPFUL HINTS
1. 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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.
2. 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 Limit 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-red.
Keep the stove free of dust and dirt.
Fuel
The P-Series Pellet Stove is approved for burning any grade
of pelletized bio-mass fuel.
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.
The moisture content of pellets must not exceed 8%. Higher
moisture will rob BTU’s and may not burn properly.
Fuel should not be stored within the stove installation
clearances or within the space required for cleaning and
ash removal.
C. Troubleshooting
With proper installation, operation, and maintenance your
appliance will provide years of trouble-free service. If you do
experience a problem, this troubleshooting guide will assist
aqualiedservicepersoninthediagnosisofaproblemand
the corrective action to be taken. This troubleshooting guide
canonlybeusedbyaqualiedservicetechnician.
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. 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.
4. Restriction in the hopper or feeder. Remove all fuel and
examine. Clear the obstruction.
5. 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 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.
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. 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.
