Discharge of flue gases
Cooking appliances must always discharge the flue
gases into special hoods, which must be connected to
chimneys or have direct access to the outside.(picture7).
If it is not possible to install a hood, it is necessary the
employment of an electric fan fitted to the external wall
or to the window, as long as there are the conditions for
the increase of the ventilation (see picture 8), reported to
the power of the fan itself. (UNI-CIG7129).
This electric fan must have the necessary power to
grant, for a kitchen, an hour air change of 3-5 times its
volume.

Connection to the gas-supply.
The cooker should be connected according UNI-CIG
7129 – 7131 directives. The appliance is tested and
adjusted to operate with the type of gas stated on the
rating plate applied in the inferior protection, closed to
the connection gas-supply pipe.
Make sure the type of gas you will use to feed the
appliance is the same indicated on the label.
In the contrary case proceed referring to the paragraph “
Adjustment to the different gas types”.
For the best performance and the lowest consume,
make sure that the gas pressure respect the values
indicated in the table “Features of the burners”.
If the applied gas pressure is different (or variable) from
the scheduled one, it is necessary to install, on the inlet
pipe, a proper gas pressure regulator for gas (NON
GPL) in compliance with UNI-CIG 7430.
The use of pressure regulators for liquid (GPL) is
permitted but it has to be in appliance to the UNI-CIG
7432 Directive.
On the terminal part of the ramp with a thread nut G 1/2”
the pipe fitting has to be mounted, putting between the
parts, the washer as indicated in picture 9. Screw the
parts without forcing, position the washer toward the
requested direction and tighten everything.
Gas connection
The connection of the hob to the gas pipe network must
be made by means of a rigid metallic pipe complying
with the UNI-CIG 7129 directive or using a flexible
connection according the UNI-CIG 9891 directive, which
can be extended to a maximum length of 2 metres. Pay
attention, in case of employment of flexible metal pipes,
they do not get in touch with moving parts or get
crushed. Pay attention even if you combine a hob and
an oven. The gas inlet washer in the appliances is
thread ½” male cylinder. Carry out the gas connection
avoiding any sort of stress to the appliance.
At complete gas connection, always verify the
perfect hold of all the washers by using a soapy
solution. Never carry out this control using a flame
