Cleaning the Vent Pipe
(Recommended Frequency of Yearly*)
Soot and Fly-Ash: Formation and Need for Removal - The products of
combustion will contain small particles of fly-ash. The fly-ash will collect
in the exhaust venting system and restrict the flow of the flue gases.
Incomplete combustion, such as occurs during start-up, 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 clean-
ing is necessary. Sweep the pipe as needed. A tee and clean-out in the
vent system attached to the stove’s flue collar will facilitate this cleaning.
Cleaning the Convection Blower
(Recommended Frequency of Yearly*)
To clean the convection blower, remove the right side door (see the
following page). Disconnect the stove power cord from the electrical
outlet. Using a 5/32” allen wrench loosen the two screws (A in Figure
48) securing the blower to the blower duct (loosen screws only - do not
remove). Slide the blower to the rear - disengaging it from the blower
duct. A vacuum can be used to remove any dust accumulation on the
blower’s blades or inside the blower duct. Caution should be used not
to damage the blower’s blades during cleaning. To reinstall the blower,
slide the blower back into the retaining lip (B) and tighten screws (A).

Cleaning the Combustion Blower
(Recommended Frequency of 1 year or after every 100 bags of fuel used*)
To clean the combustion blower, remove the six nuts labeled A in Figure
47 with an 11/32” wrench. After removing these nuts, the motor with
fan attached can be pulled from the fan housing. The fan blades and the
fan housing can be vacuumed once the motor is removed. Before rein-
stalling, vacuum out the blower housing and flue passageway leading to
the combustion blower. When reinstalling the motor, a new gasket may
need to be installed between the motor and the fan housing. To complete
the reinstallation, place the motor back on the fan housing and reinstall
the six nuts. Make sure the motor’s green ground wire is secured under
one of the nuts.

may require more frequent cleaning and stove maintenance.
