ADMITTED / NOT ADMITTED FUEL
The fuels admitted are wood logs. One must use only logs of dry wood
logs should be 30 cm's long and 30 cm's max in circumference.
The wood used as fuel must have a moisture contents lower than 20 %, which is obtained after at least 1 year drying
(tender wood) or 2 years (hard wood) and must be stored in a dry and ventilated place (for ex. under a shed). The wet
wood makes ignition more difficult because it is necessary a greater quantity of energy to evaporate the existing
water. The humid contents has the disadvantage that, with the temperature lowering, the water condensates first in
the hearth and then in the chimney. The unseasoned wood contains about 60 % of H20, then it is not suitable to be
burnt. The following cannot be burnt: rests of coal, cutoffs, parts of barks and panels, wet wood or treated
with varnished, plastic materials. In this case the guarantee on the appliance lapses. Paper and carton must
be used only for ignition.
The combustion of wastes is forbidden by national law on the protection against emissions. This may damage the
stove and the chimney, causing health damages and claims by the neighbourhood owing to the bad smell.
The wood is not a fuel which allows a continuous operation of the appliance, as consequence the heating all over the
night is not possible.

ATTENTION: the continuous and protracted use of aromatic wood (eucalyptus, myrtle etc.) quickly damages the cast
iron parts (cleavage) of the product.

AIR ENTRANCE INTO THE INSTALLATION PLACE DURING THE COMBUSTION
As the stoves take their combustion air from the installation place, it is MANDATORY that a sufficient quantity of air is
introduced in the installation room itself.
In case of tight doors and windows (for example houses built according to the energy saving criteria) it is possible that
the air entrance is not guaranteed, compromising the draught, the welfare and the security of the people. It is
necessary to guarantee a further air entrance through a external air intake, to be positioned in the nearby of the
