Monthly Cleaning- continued:
Clean the heat exchanger with scraper as shown in Figure
2.4. Brush or scrape the inside of the stove to remove fly ash.
Remove the ash pan and dispose of ashes in an approved
manner, according to local codes.
The exhaust passage may need cleaned as well. Keep
in mind the ESP Sensor is located just inside the exhaust
passage Figure 2.7. Be sure not to damage the ESP Sensor
while cleaning this area.
• Remove the combustion blower by loosening the 2 Thumb
Screws and Rod (Figure 2.5), twisting the combustion
blower mount plate counterclockwise to unlock, and
pulling the blower out.
• Clean the combustion blower housing and fan blade with
a brush and a vacuum cleaner Figure 2.6.
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.
NOTE:
THE STOVE MUST BE COMPLETELY OUT BEFORE
YOU VACUUM THE STOVE. LIVE PELLET EMBERS, IF
SUCKED INTO THE VACUUM, WILL LIGHT THE VACUUM
ON FIRE AND MAY ULTIMATELY CAUSE A HOUSE FIRE.
Use a brush to clean the flue, being careful not to damage
the ESP probe Figure 2.7.
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.
Slide ash pan into the stove and latch the door.
