8. Clean the combustion blower wheel with a brl~sh 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 HEPAfilter or a vacuum specially made
for fly ash and soot. USING A VACUUM WHICH IS
NOT EQUIPPED 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-

9. Use a brush to clean the Rue, 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.

Soot and Fly Ash
The products of combustion will con-
tain small particles of fly ash which must
be removed from the inner walls of the
stove and from the venting system peri-
odically. 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.
Be careful not to
damage ESP probe
when cleaning with
Fig. 31 brush.
