CAUTION: Surfaces are hot while in operation, Wear
gloves to protect from burns.

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.

Insert spring latch front hooks into the ash pan side slots.
Push both latches to the rear at the same time to latch.
When removing the ash pan to empty ashes, you will
note a build up of ash nes behind the ash pan. This space
behind the ash pan was designed to allow the nes to fall
out of the vertical heat exchangers and collect where they
are easily cleaned out, rather than going into the ue pipe
where it would be difcult to clean. These nes should not
be allowed to build up. They may not allow the ash pan to
be seated into its gasket properly. NOTE: If an extreme
amount of force is required to snap the latch on one or
both sides of the ash pan, the area behind the ash pan
should be checked for ash build up.

Maintenance - Emptying Ashes
Soot and Fly Ash
The products of combustion will contain small particles
of y ash. The y ash will collect in the exhaust venting
system and restrict the ow of the ue 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 sys-
tem. The ENTIRE venting system should be professionally
cleaned at least once each year.

21
Opening:
The view door must be opened for cleaning of the glass
and scraping of the burn pot. This should be done with
the unit off and cool, in most cases. Although the glass
can be cleaned and burn pot scraped while the unit is
at low burn.
1. Using scraper as shown in Fig. 34 and 35, lift the door
latch forward and up.
2. Swing the door open to the left, stopping the swing
when resistance is felt. Forcing the door open further
than it is designed, may cause damage to the door or
it's hinges.
CAUTION
Do not put excessive downward pressure on the
latch end of the door while in the open position.
If the door is going to be opened for an extended period
of time, it is suggested that it be removed (see Fig. 36)
and set safely aside.
3. Inspect the door gasket and glass gaskets for worn or
missing pieces. Replace if necessary. (Fig. 37)
Closing:
When closing the door, always hold the door latch all
the way up until it has caught the receiving bolt. Then
push the latch downward and back until the door is fully
seated. See Fig. 35.
Removing View Door:
To remove the view door from the stove, hold the door
by the bottom and lift upward, off of the hinge pins. See
Fig. 36.
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.
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 gas-
ket materials prior to replacing the glass.
Lay the door face down on a at surface. Re-
move the glass retainers and screws. Apply the
gasket material to the face of the new glass.
Lay the glass into the door. Lay the glass
retainers into position and install the nuts.
Tighten each nut evenly, to avoid making any
stress points.

Burn Pot Cleaning and Maintenance
1. Scrape the top holed surface and sides of the
burn pot. (Fig 38) 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. 38)
3. Lift off the clean-out cover (Fig.39) to open the
bottom clean-out chamber. (Fig.40)
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 40
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. See page 25.
Warning
Use caution when cleaning burn pot clean-
out chamber. Do not damage the high
temperature igniter wires.

While holding the brick panel up with one hand,
remove the ame guide from the top of the burn
pot.

Slide the brick panel into the left corner of the
rebox with the panel resting on the top edges
of the burn pot. Rotate the right side of the brick
panel through the door opening.
Reverse this operation to reinstall the brick
panel after cleaning.

Cleaning and Maintenance for the
Combustion Intake Cover
You will need to remove the combustion intake cover,
behind the ash pan, to clean the fan blades and rear
ue tube.
Figure 46
Rotate the retainer cover handle counter-clockwise
upward as far as it will go (approximately 90o).
Figure 47
Hold the intake cover handle and pull until the side of
the cover at the retainer handle end comes away from
the stove body, approximately 15-20o, slide the right
side tab out of the retaining slot.
Figure 48
Clean and inspect the fully exposed combustion fan
blade and ue tube.
Reinstall the combustion intake cover by rst sliding the
right side tab into the retainer slot seen in Figure 47.
Rotate the cover inward until the cover ts into its
hole.
Make sure the two faces (Fig.46) of the cover and
retainer spacer are even and rotate the retainer handle
clockwise until it stops.
Creosote Guidelines:
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.

Cleaning the Heat Exchanger System
1. Remove brick panel and ame guide. (See Pg 23.)
2. Remove the ash pan. See Page 20.
3. Remove ue bafes located on each side of the
burnpot, see Fig. 49 & 50. The bafe is held in place
by inserting the tab into the slot (located toward the
outside of the rebox) and resting it on the hook tab
located beside the burnpot.
4. Pull the pointed end of the bafe slightly front with
one hand while pushing up from below with the other
hand. See Fig. 50.
5. With the bafe released from the tabs, rotate the
pointed end toward the door opening. Lift bafe up
and out.
The right and left bafe are interchangeable.
6. Now remove the heat exchanger bafe plates. See
Fig. 51 & 52. To remove the left plate, slide the center
lock to the right. To remove the right plate, slide the
center lock to the left. (The right and left plates are
interchangeable.)
This will allow access to all of the rear vertical heat
exchanger surfaces.
7. With all four bafe plates removed, cleaning can be
performed with the arrow end of the scraper. See Fig.
53.
8. Scrape all of the heat exchanger surfaces. (Be sure
to clean any internal ledges where y ash could have
collected.)
