Removing Ashes:
Fuel quality and moisture content will dictate how
often it will be necessary to empty the ash pan.
Disposal of Ashes
Ashes should be placed in a metal container with
a tight tting lid. The closed container of ashes
should be placed on a noncombustible oor or
on the ground, well away from all combustible
materials, pending nal disposal. If ashes are
disposed of by burial in soil or otherwise locally
dispersed, they should be retained in the closed
container until all cinders have thoroughly
cooled.
It is recommended that the stove is cold and shut
down for removing the ash pan.
1. Open the front door of the stove and then open
the ash door by pulling downward on the ash lip.
Remove the ash pan (be sure to wear protective
gloves if the stove is not cooled down). See Fig.
33.
2. Slide the ash pan back into the stove, seating it
againsttherearoftherebox.Lifttheashlipto
close the ash door and then close the front door
of the stove.
Cleaning:
The stove should be cleaned after burning ap-
proximately 1 ton of pellets (50 bags). The cleaner
thestove,themoreefcientitwillbe.Youwillburn
less pellets and heat output will be greater.
Note: Higher ash content pellets will require more
frequent cleaning.
1. Shut down the stove and disconnect power cord
to insure that all motors are stopped.
2. Clean the heat exchanger with scraper as shown
ing34.
3. Brush or scrape the inside of the stove to remove
yash.
4.Scrapetheburnpotwiththeatendofthescraper
provided with the stove. Inspect the holes on the
burn pot surface. See Fig. 35.
5.Opentheburnpotclean-out.Cleanyashfrom
the burn pot and replace the cover. See Figures
39 and 40 on page 24.

6. Remove the ash pan and dispose of ashes in an ap-
proved manner, according to local codes.
7. Remove the combustion blower by loosening the
3 wing nuts, twisting the combustion blower mount
plate counterclockwise to unlock, and pulling the
blower out.
8.Cleanthecombustionblowerwheelwithabrushand
a vacuum cleaner. Note: Do not use a household
vacuum to clean the stove. We recommend that you
useashopvacuumthatisequippedwithanedust
ltercalledaHEPAlteroravacuumspeciallymade
for y ash and soot. USINGA VACUUM WHICH
IS NOT EQUIPPED WITH A FINE DUST FILTER
WILL BLOW FLY ASH AND SOOT OUT INTO THE
ROOM.
NOTE: THE STOVE MUST BE COMPLETELY OUT
BEFORE YOU VACUUM THE STOVE. LIVE PEL-
LET EMBERS, IF SUCKED INTO THE VACUUM,
WILL LIGHT THE VACUUM ON FIRE AND MAY
ULTIMATELY CAUSE A HOUSE FIRE.
9.Useabrushtocleantheue,beingcarefulnotto
damage the ESP probe.
10. Reinstall the combustion blower by turning plate
clockwise to lock into place and tightening the 3 wing
nuts.Besurethefanplateisushwiththeexhaust
housing on the stove body and the motor armature
points up toward the hopper.
11. Slide ash pan into the stove and latch the door.

Soot and Fly Ash
Formation and Need for Removal - The products
of combustion will contain small particles of yash.
The yash will collect in the exhaust venting system
and restrict the ow of exhaust gases. Incomplete
combustion, such as occurs during startup, shutdown,
or incorrect operation of the room heater will lead to
some soot formation which will collect in the exhaust
venting system. The entire exhaust venting system
should be professionally cleaned at least once
every year.
Removingyashandsootimprovesefciencyand
insuresthattheueventingpassagewayisclearandun-
obstructed. The stove should be cleaned after each ton
of pellets (50 bags) and the venting system inspected
and cleaned after each heating season.

Burn Pot Cleaning and Maintenance
1. Scrape the top holed surface and sides of the burn
pot. (Fig 39) It is not necessary to completely remove
all loose material from the burn pot. The excess will be
pushed out during the next use.
2. Loosen the (2) wing thumb screws on the lower front
angle of the burn pot. (Fig. 39)
3. Lift off the clean-out cover (Fig.40) to open the bottom
clean-out chamber. (Fig.41)
4. Clean ash buildup from inside the chamber while
cover is off. Use the scraper to tap on the top front
edge of the burn pot. This will help knock pieces of
ash, loosened by the scraping process, down through
the holes. It also helps knock scale off of the igniter
element.
Figure 41
The igniter is made to be removable for service
by insulated male/female wire connectors. These
connections between the hot leads (the wires inside
the burn pot) and the cold leads (the wires from the
control board) are always pulled to the rear of the
feeder body. (Not coiled inside the burn pot.)
It is very important that these connections are to the
inside rear of the feeder body. Also, the extra wire of
the igniter wire service loop must be pulled out through
the rear of the feeder and tied up so that it will not be
damaged by any moving parts.

DANGER
Disconnect the power to the unit before
removing cover.

must always be pulled to the rear of the
feeder body before operation.
WARNING
Use caution when cleaning burn pot clean-
out chamber. Do not damage the high
temperature igniter wires.
Burn pot igniter
Whenever wood is burned, there is a potential for
creosote formation. The venting system should be
inspected periodically during the heating season to
determine if a creosote buildup has occurred. If a
signicantlayerofcreosotehasaccumulated(3mm
or more), it should be removed to reduce the risk of a
chimneyorventingsystemre.

The glass in your Harman stove is a special ceramic glass.
Do not abuse the glass by striking or slamming the door.
Never burn the appliance if the door glass is cracked or
broken.
Replace only with Harman supplied glass.
Sootand/ory-ashmayaccumulateontheviewingglass,
and will ocassionally need to be cleaned. Clean the glass
with a soft cloth and mild glass cleaner. Do not clean the
glass when hot, and avoid the use of abrasive cleaners.
Glass replacement
Carefully remove all remaining glass and gasket materials
prior to replacing the glass.
Laythedoorfacedownonaatsurface.Removetheglass
retainers and screws. Apply the gasket material to the face of
the new glass. Lay the glass into the door, making sure that
the glass is contained within the channels and raised areas
of the door itself. Lay the glass retainers into position and
install the screws. Tighten each screw evenly to avoid making any stress points.
