when cleaning with
brush.
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 fine dust filter called a
HEPA filter or a vacuum specially made for fly 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.

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 flush 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 flyash. The flyash
will collect in the exhaust venting system and restrict the
flow of the flue 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.
Removing fly ash and soot improves efficiency and 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.
If You Experience a Soot or Creosote Fire; Turn the mode
slector dial to the "OFF" position. Allow the unit to shut-
down. Do NOT disconnect the power to the appliance.
Do NOT open the appliance door or hopper lid. Contact
your dealer to have the unit professionally inspected and
cleaned prior to use.
