inside the connection pipe must correspond to the external diameter of the smokes exhaust small trunk of
the stove. This is ensured by pipes according to DIN 1298.
ATTENTION: Eventual flammable pieces in the area of 20 cm round the connection pipes must be
changed with fireproof and not sensitive to heat materials.
For a good operation of the equipment it is essential that in the installation place it is introduced sufficient
air for combustion (see chapt. 7).
The depression on the chimney should be 12 - 13 Pa (=1.2 – 1.3 mm of water column). The measurement
must be done always with the equipment hot (rating calorific value). When the depression exceeds 17 PA
(1.7mm of water column) it is necessary to reduce the same with the installation of an additional flue
adjuster (butterfly valve) on the exhaust pipe or in the chimney.
For safety reasons the door of the stove must be opened only for the loading of the fuel or for
removing the ashes, while during the operation and the rest, the door of the hearth must remain
closed.

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 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 hypothesis, transforms the flue into an external
air intake, by sucking the smokes of the rooms with dangerous consequences for the people.
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 ).

ADMITTED/NOT ADMITTED FUEL
The fuels admitted are wood logs. One must use only logs of dry wood (water content max. 20 %). The
size of wood logs should be 30 cm's long and 30 cm's max in circumference.
