11.4. CLEANING OF THE HEARTH GRATE

The use of not suitable fuel, as for example wood with sand, prevents the correct sliding of the cast-iron grate and can lead it to the
complete blockage. In this case you should arrange for a removal of the dirty sediments from the surfaces of the grate and its holder
Picture 8 at page 41 A.

11.5. CLEANING THE FLUE

The correct lighting phase, the use of proper quantities and types of fuels, the correct position of the secondary air regulator, enough
draught of the chimney-flue and the presence of combustion air are the essential elements for the optimal functioning of the appliance.
The device should be completely cleaned at least once a year or every time it is needed (in case of bad working and low yield). An
excessive deposit of soot can cause problems in the discharge of smokes and fire in the flue.
The cleaning must be carried out exclusively with cold equipment. This operation should be carried out by a chimney sweeper who
can simultaneously perform an audit of the flue (checking of possible deposits).
During the cleaning, it is necessary to remove the ash drawer, the grating, and the smoke deflectors from the device in order to ease the
fall of the soot. The deflectors can be easily extracted from their seats since they are not fastened using screws. Once the clearing has
been carried out, place them back in their seats.
CAUTION: The lack of the deflectors causes a strong depression, with a too fast combustion, an excessive consumption of wood
with related overheating of the device.
