soot and Flyash: 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 flue gases. Incomplete
combustion, such as occurs during start-up, shut-
down, 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. Most retailers offer a
cleaning service for their customers. The best time to have
this cleaning performed is after the heating season.

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 fly ash 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.
note: THE STOVE MUST BE COMPLETELY OUT
BEFORE YOU VACUUM THE STOVE. LIVE PELLETS, IF
SUCKED INTO THE VACUUM WILL LIGHT THE VACUUM
ON FIRE AND MAY ULTIMATELY CAUSE A HOUSE FIRE.
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 blower cover and relatch.
11. Slide ash pan into stove and latch the door.
