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
open doors, loose or missing gasket on doors or
hopper lid, 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.
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
creasote 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. Combus tion intake assembly not prope rly
latched.
7. No fuel in hopper
SMOKE SMELL
Seal the vent pipe joints and connection to frame
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 draft motor 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.
Trouble-Shooting
Cleaning Burn Pot
Whenever your stove is not burning, take the op-
portunity to scrape the burn pot to remove carbon
buildup. A vacuum cleaner is handy to remove the resi-
due. 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 re-
quired. 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 Accentra 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 con-
tent will require more frequent ash removal 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 Accentra.
The moisture content must not exceed 8%. Higher
moisture will rob BTU's and may not burn properly.
