8. 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 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 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 9).
The depression on the chimney (draught) should be 10 Pa (=1.0 mm of water column). The measurement
must be done always with the equipment hot (rating calorific value). When the depression exceeds 17 PA
(1.7 mm of water column) it is necessary to reduce the same with the installation of an additional flue
adjuster (false air valve) on the exhaust pipe or in the chimney.
For safety reasons the door of the hearth may be opened only during the loading of fuel. The hearth must
remain closed during the operation and the periods of non use.
9. 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
