Using the poker, remove loose and baked on ash from
the upper part of the combustion chamber. Sweep the
ash backwards into the heat exchanger or forwards
onto the moving grate.

A thin coating of ash (~ 5 mm) may remain on the
lining. This does not adversely affect operation
and acts as an additional protective layer. Significant
discolouration of the lining is normal.
CAUTION!
Never treat the lining with force, as this may cause
parts of it to be knocked off.
Open the combustion chamber door and remove
baked on ash deposits from around the opening and
from the combustion chamber door

Next, using the poker, remove baked on ash deposits
from inside the combustion chamber and sweep onto
the moving grate.

A thin coating of ash (~ 5 mm) may remain on the
lining. This does not adversely affect operation
and acts as an additional protective layer. Significant
discolouration of the lining is normal.
Then re-insert the combustion chamber temperature
sensor in the opening and secure with the screw.
Removing ash deposits near the opening of the
secondary combustion zone
Remove ash deposits around the opening of the
secondary combustion zone and also from the
maintenance cover.
