6. Remove the ash pan and properly dispose of the
ashes.
7. Remove combustion blower cover by turning the
blower cover latch vertical, see Fig.26. Sliding the
cover out of the slot on the left. This will expose the
combustion blower wheel and flue outlet, Fig.27.
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 ashes and soot. using a vacuum which is
not equipped with a fine dust filter may clog and
disperse fly ash and soot into the room.

9. Use a brush to clean the flue, being careful not to
damage the ESP probe, see Fig. 30. The flue goes
straight through into the vent pipe (Fig.27) therefore,
the vent pipe can also be cleaned, to some extent,
through the flue outlet.
10. Reinstall the blower cover and close the latch.
11. Slide the ash pan into 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.
Be careful not to
damage ESP probe
when cleaning with
brush.
