Maintenance Of The
Ash-extraction System
Step 1: refer to Diagram 21 to determine
the condition of the three stainless steel ash
screws. It can happen that the sugar released
by the fuels containing corn or wheat can stick
on the ash screws resulting in poor movement
and removal.
Diagram 21
Step 2: Use a 9/16 wrench to unscrew the
two nuts (Diagram 17). Then to raise the ring,
it may be necessary to insert a fl at screwdriver
between the outside of the burn-pot and the
top ring (Diagram 18). If required, use a rubber
mallet to loosen.
Step 3: Refer to Diagram 22. It is advisable to
support the ash extraction system before you
undo these 9/16" nuts as once they are removed,
the ash extraction system will become loose and
drop down. The "lovejoy" connection wil now be
loose. This is an important part that must not be
misplaced or forgotten when re-assembling.

Maintenance On The Combustion
Fan (Connected To The Chimney)
There are two ways to clean the fan fl ywheel,
either directly on the stove (Diagram 23) or
removing the fan from the stove (Diagram
24).

To clean the flywheel, use a steel brush
shown on Diagram 24. Clean each wing of the
fl ywheel, which will increase the pressure on the
calibration indicator and will reduce vibrations
caused by accumulated ashes.

Maintenance On The
Convection Fan
To reach the convection fan, remove the control
panel (refer to diagram 25 & 26). Then using
a brush and a vacuum cleaner, clean each
plastic impeller which will increase the hot air
volume displacement in the room and reduce
or eliminate any vibrations.

Maintenance On The
Fuel Feeding System
At least once every year, empty the fuel hopper
using a vacuum cleaner with fi lter, clean the
fuel residues accumulated which are stuck at
the bottom of the feed screw close to the nylon
bushing (see Diagram 27).
