CONNECTION TO THE CHIMNEY

For safety reasons the door of the appliances with constructive system 1, 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.
The appliances with constructive system 2 must be connected to their own flue. The operating with open
door is allowed under supervision.
The stove is endowed with an upper exhaust pipe. The connection pipe to the flue must be the shortest
possible, right, tight and according to the current regulations.
The connection to the chimney must be performed with stable and strong pipes (we recommend a
thickness of 2 mm). The pipe for smokes exhaust must be fixed hermetically to the chimney. The diameter
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'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.
In order to increase the yield of the stove, it is possible to ask for a
device to be filled in the smoke pipe exhaust, as indicated in the Picture 8, pos. A
7.

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 25 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.
