11.4 Cleaning the fire box

Before performing any maintenance operation,
take the following precautions:
1) Make sure that the grate (A) (Fig. 43) is free from
any combustion residues that may obstruct
the free passage of air. Remove it and clean
the fire box using a hand brush (not supplied)
conveying the combustion residues into the
ash drawer. Pay attention to any burning
embers.
Place the grate carefully on a suitable
support surface.
2) Extract the ash drawer (B) from the base and
vacuum out any ash deposited in the com-
partments below (Fig. 44).
The ash drawer below the fire box
must be emptied out every day to stop
it from filling up with ash, thus caus-
ing the cast iron grate of the fire box to
overheat and preventing the flow of air
to the fire box.
3) Vacuum the front and rear holes (C) of the com-
bustion air distributor in order to avoid any
accumulation of ash (Fig. 44).

The refractory bricks undergo expan-
sion deformations during the opera-
tion of the appliance, due to the high
temperatures reached. For this reason
the slots open between one piece and
another of the refractory bricks should
be considered normal. During com-
bustion these slots are filled from the
ashes which absorb the expansions of
the refractory bricks.
