Trouble-Shooting - Harman Stove Company Accentra Installation & Operating Manual

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. 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 fire.
5. Restriction in the hopper or feeder. Remove all
fuel and examine. Clear the obstruction.
6. 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 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. Combustion blower fan blades may need
cleaned.
6. Fuel restrictions as noted above.

residue. Be sure the stove is cold if you use a vacuum.
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
30 minutes before removing ashes. This will result in a
cooler stove and ash pan.
in most cases. Operating in the normal range (#4)
is recommended when maximum heat output is not
required. The ESP prevents the stove from being over-
fired.
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, or up to a 50% corn and pellet mixture, due
to a patented feeder and burn pot system.
It should be noted, however, that higher ash content
pellets, and a corn mixture will require more frequent
ash removal and may provide less BTU's per pound.
The moisture content of pellet fuel must not exceed
8%, corn should be 15% or less. Higher moisture will
rob BTU's and may not burn properly.
Keep fuel in a dry location. Do not store fuel within
the installation clearance area of the room heater.
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.
