Minimizing Creosote:
Whenever wood is burned slowly, the potential exists for creosote
to form in the venting. The chimney or venting system should be
inspected periodically throughout the heating season to determine if
acreosotebuilduphasoccurred.Ifasignicantlayerofcreosotehas
accumulated (3mm or more), it should be removed to reduce the risk
ofachimneyre.Aprofessionalchimneysweepisrecommended,
since they would normally have the correct equipment to ensure
proper creosote removal.
If you experience a re in the venting system, turn the stove to
"OFF"toallowtheunittoshutdown.Calltheredepartment,andbe
sure everyone is out of the residence. Before re-using the appliance,
have the venting system thoroughly inspected and replace any
damaged components.
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 occasionally
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 clean-
ers.
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 chan-
nels 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.

Scraping the burn pot:
Whenever adding fuel to the hopper, take the time
and scrape the grate surface of the burnpot, using
the scraper tool provided. This can be done while a
reisburning.Wearingheatresistantgloves,open
the rebox door. Scrape any accumulated ashes
frominfrontofthere,intotheashpan.Now,scrape
underthere,inadownwarddirection,toloosenany
carbondeposits.Donotscrapethereoutofthe
pot. Whatever you loosen will be pushed out with
theowofnewfuelintothepot.(Fig.33)
Removing Ashes:
After approximately 1 ton of pellets has been
burned, it will be necessary to empty the ash pan.
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 com-
bustible materials, pending nal disposal. If
ashes are disposed of by burial in soil or other-
wise 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 when removing the ash pan.
1. Lift the latch handle to open the ash door and
remove the ash pan. Use ash pan handle to carry
and dispose of ashes.
2. Slide the ash pan back into the stove and latch
the door by pushing down on the latch handle
when closed.
Cleaning:
The stove should be shut-down and thoroughly
cleaned after each ton of pellets consumed. The
cleanerthestove,themoreefcientitwillbe.
Note: Fuel with higher ash and/or moisture
content will require more frequent cleanings.
1. Shut down the stove and disconnect power cord
to insure that all motors are stopped.
2. Clean heat exchanger with scraper as shown in
g27.
3. Brush or scrape the inside of the stove to remove
yash.
4.Scrapeburnpotwithatendofscraperprovided
with the stove. Inspect the holes on the burnpot
surface. See Fig. 33.
5.Openburnpotclean-out.Cleanyashfromburn
pot and replace cover.

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 ashes and soot. Using a vacuum which is
not equipped with a ne dust lter may clog and
disperse y ash and soot into the room.
NOTE: THE STOVE MUST BE COMPLETELY
OUT BEFORE YOU VACUUM THE STOVE. LIVE

LIGHT THE VACUUM ON FIRE AND MAY ULTI-
MATELY CAUSE A HOUSE FIRE.

Soot and Fly Ash
The products of combustion will contain small
particlesofyashwhichmustberemovedfrom the
inner walls of the stove and from the venting system
periodically.Removingyashandsootimprovesef-
ciency,insuresthattheueventingpassagewayisclear
and unobstructed. 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 33) It is not necessary to completely remove all
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. 34)
3. Lift off the clean-out cover (Fig.35) to open the bottom
clean-out chamber. (Fig.36)
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 36
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.
WARNING
Use caution when cleaning burn pot clean-out
chamber. Do not damage the high temperature
igniter wires.
