Maintenance Of The
Combustion Chamber
STEP 1:
Once a month, use a "shop-vac" style
vacuum cleaner (avoid the use of a domestic
style vacuum cleaner) with fi lter (only when the
stove is cold) to remove the ashes accumulated
around the burn-pot (Diagram 12). Clean the
interior of the glass door. Use the "shop-vac"
style vacuum cleaner brush to clean the pipes
of the convection system (Diagram 13) as well
as the 2 air intakes (Diagram 14).

Maintenance Of The Burn-pot
Step 1:
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

Step 3:
if necessary, use a steel brush installed
onto a drill to remove minerals stuck to the interior
wall of the cylinder.
Step 4:
use a rod which has a diameter of 1/8"
(3 mm) to clean the jets of the inner burn-pot
(Diagram 20). Be sure to install the burn-pot
cylinder correct way up. Angled holes to the
top, straight holes to the bottom.

MAINTENANCE
STEP 2:
The frequency of cleaning varies
according to the type of fuel burned (see the
maintenance charts) For an in-depth cleaning,
repeat STEP 1. It maybe necessary to use a
rubber mallet to remove the four cleaning doors
inside the fi rebox. Then use a 7/16 wrench
to remove the brass bolts of the two access
doors (Diagram 15). Hold the vacuum cleaner
under the side wall and use a rubber mallet to
lightly knock out accumulated ashes which are
inaccessible with the vacuum cleaner (refer to
Diagram 16).
Before reinstalling the access doors refer to the
section on the maintenance of the combustion
fan. (clean the wings on the fl ywheel).
Step 2:
remove the cylinder from inside the
burn-pot (Diagram 19).
