THE MANUFACTURING COMPANY DECLINES ANY RESPONSABILITY FOR POSSIBLE DAMAGES
RESULTING FROM AN INSTALLATION WHICH DOESN'T COMPLY WITH THE RULES IN FORCE
INSTALLATION ENVIRONMENT
Warning - This unit can be installed and can work only in constantly ventilated rooms, according to UNI 7129 e UNI
7131.
In order to make the gas unit work properly, it is necessary that air sufficient to gas combustion can naturally flow in
the room. (The installer must follow the rules in force UNI-CIG 7129; 7131).
The air flow into the room must come directly through openings of external walls - See fig. 19 - 20.
These openings must have a free passage of at least 200 cm
2
(one or more openings can be made).
Fig. 21
Fig. 22
These openings (or opening) should be realized in such a way not to be occluded both from inside and outside and
preferably positioned near the floor, opposite the combustion products discharge. In case these systems can't be
realized in the room where the unit is installed, the necessary air can come from a room nearby, provided that this
room is not a bedroom or a dangerous environment and it is ventilated as requested. (rules UNI-CIG 7129).
COMBUSTION PRODUCTS DISCHARGE
Gas cooking units must discharge combustion products through hoods directly connected to flues or outside (Fig. 21).
In case the hood can't be installed it is recommended the use of an electric fan applied to the external wall or to the
window of the room, provided that in that room the openings to let air flow in are realized (UNI-CIG 7129) (Fig. 22).
This electric fan must be powerful enough to ensure in a kitchen an air replacement of 3 to 5 times its volume per hour.
