Cleaning the Heat Exchanger
The accordion heat exchanger surfaces are the pri-
mary source of heat transfer into the room. Therefore,
it is very important to keep them clean from flyash and
soot buildup.
•
The heat exchanger surfaces should be cleaned af-
ter approximately every 1 ton of pellets are used.
•
Use the scraper provided to clean all the way into the
point.
•
Note: An old paint brush works well to clean these
surfaces.
•
Note: The unit “must be cold” before using anything
other than a wire brush.
•
There are 2 primary air inlet holes on the rear flange
of the burnpot. They should be checked for blockage
and cleaned with a vacuum if necessary. Note: The
bottom of the flame guide has 2 notches that match
the holes.
Cleaning the Heat Exchanger tubes
Using the cleaning brush provided, clean these tubes
after every 1 ton of pellets are used.
These tubes are an important part of the heat ex-
changer. Efficiency will be lost if they are not properly
maintained.
Note: The brust will only extend into the fight side tube
approximatlely 12”, but the left side tube requires the
total length of the brush to be used.
There is a 2" square exhaust tube on each side (lower
left and right corners) of the firebox. They can only be
seen with the cast heat exchanger covers removed.
