Remove ash pan and dispose of ashes in an ap-
proved manner, according to local codes.
Remove combustion blower by loosening the 3
wingnuts, twisting the combustion blower mount plate
counterclockwise to unlock, and pulling the blower
out.
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 fine dust
filter called a HEPA Filter or a vacuum specially made
for fly ash and soot. USING A VACUUM WHICH IS
NOT EQLIIPPED WITH A FINE DUST FILTER WILL
BLOW FLYASH AND SOOT OUT INTO THE ROOM.
NOTE: THE STOVE MUST BE COMPLETELY OUT
BEFORE YOU VACUUM THE STOVE. LIVE PEL-
LETS, IF SUCKED INTO THE VACUUM WILL LIGHT
THE VACUUM ON FIRE AND MAY ULTIMATELY
CAUSE A HOUSE FIRE.

the fan plate is flush with the exhaust housing on stove
body and motor armature points up toward the hop-
per.

Soot and Fly Ash
Formation and Need for Removal
-
The products
of combustion will contain small particles of flyash.
The flyash will collect in the exhaust venting system
and restrict the flow of the fuel 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 exhaust venting
system should be inspected at least once every year
to determine if cleaning is necessary.
The products of combustion will contain small
particles of fly ash which must be removed from the
inner walls of the stove and from the venting system
periodically. Removing fly ash and soot improves
efficiency, insures that the flue 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.
