AIR ENTRANCE INTO THE INSTALLATION PLACE DURING THE COMBUSTION

As the stoves take their combustion air from the installation place, it is essential 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 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 m
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 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)
even if the hearth door closed. As consequence a contemporary operation of
the hoods is not possible.
The depression in an extraction hood can at worst hypothesis,
transforms the flue into an external air intake, by sucking the smokes of
the rooms with dangerous consequences for the people.
IMPORTANT: 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environment, the stove combustion air can be directly withdrawn at the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 SERIES junction Picture 12

ADMITTED/NOT ADMITTED FUEL

The fuel admitted is made of wood logs. One must use only logs of dry wood (water content max. 20 %). The wood
pieces should have a length of 20 cm. and a maximum circumference of 30 cm's.
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.

Among the others, the following cannot be burnt: remainders of coal, cut-outs, scraps of bark and panels,
humid wood or treated with varnishes, plastic materials; in this case the warranty on the equipment expires.
Paper and carton must be used only for ignition. The combustion of wastes is forbidden and may damage the stove
and the chimney, causing health damages and claims by the neighbourhood owing to the bad smell. The wood is not
