the people. It is necessary to guarantee a further air entrance through an external air intake, to be
positioned in the nearby of the appliance or through air connection towards outside or a near ventilated
room, with the exception of thermal units place or garages (FORBIDDEN).
The connection pipe must be flat with a minimum diameter of 120 mm, a maximum length of 4 m and with
no more than 3 bends. If there is a direct connection with the outside it must be endowed with a special
windbreak.
The air entrance for combustion into the installation place must not be closed during the operation of the
stove. It is absolutely necessary that in the environment in which the stoves operate with the natural flue of
the chimney, it is introduced as much air as necessary for the combustion, i.e. up to 20 m³/hour.
The natural recirculation of air must be ensured by some fixed openings on the outside. The size of the
necessary openings for air is fixed by the relevant prescriptions. Ask for information to your chimney
sweeper. The openings should be protected with grids and should never be obstructed.
An extraction hood (aspirating) installed in the same room or in a room nearby, causes depression with
output of combusted gasses (smoke, smell). As consequence the
extraction hoods should not work at the same time of the stove.
The depression in an extraction hood can at worst

OPTIONAL
For a better comfort and corresponding oxygenation of
environment, the stove combustion air can be directly withdrawn at
the outside. In order to do that, the stove can be connected to the
external air socket by an optional junction ( Picture 8 - A) ( Kit Ø
120 ).

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, cut-offs, parts of barks and panels, wet wood or treated with varnished, plastic
