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's 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 chapter 7).
The depression on the chimney should be 12 Pascal (= 1.2 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 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, in case of insufficient flow of fresh air may negatively affect the
functions of your appliance with the output of combusted gasses
(smoke, smell even if with the door closed). As consequence the
extraction hoods must not absolutely work at the same time with 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

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.
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 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.
