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 connection pipe to the flue must be the shortest possible, right, tight
and according to the current regulations.
The junction pipe must be short, straight and tight.
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 cooker. 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 Pa (= 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.

AIR ENTRANCE INTO THE INSTALLATION PLACE DURING THE COMBUSTION

As the cookers 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.
