Installation room
The room where a gas appliance is installed must have a natural inflow of the air needed f
or
combustion of the gases.
The air must enter the room directly through one or more openings having a free cross-section of at
least 100 cm2 (A). In case of appliances without safety valve, this opening must have a cross-
section
of at least 200 cm2 (fig.
11).
This opening must be constructed so that it cannot be obstructed from the inside or outside,
and must be located close to the floor, preferably on the side opposite to the combustion gas
discharge side.
When it is not possible to make the necessary openings, the air required may come from an adjacent
room, ventilated as required, provided this room is not a bedroom, a hazardous room, or at a vacuum.
Discharge of combustion gases
Gas cooking appliances must discharge their combustion gases by means of hoods connected
directly to chimneys or to the outdoors (fig. 11).
If installation of a hood is not possible, an electric fan connected to an outside wall or the window of
the room must be installed. This electric fan must have a flow-rate capable of ensuring an air
exchange in the kitchen of at least 3
-
5 times its volume.

Connection to the gas system
Before installation, check that the local supply conditions (gas type and
pressure) are compatible with the hob's settings. To do this, check the data on
the product nameplate applied to the hob and in this manual.
The gas connection must be carried out by a qualified technician in compliance with local current
regulations.
If using metal hoses, ensure these do not come into contact with any movable parts and are at no
point crushed.
Carry out the connection in such a way as does not cause any stress whatsoever on the app
liance
.
When using metal hoses, check that they do not touch mobile parts and are not crushed.
Make the connection so that no stresses of any kind are applied to the appliance.
The gas intake connection has a G½" thread conical. (Fig.16)
No gasket is requi
red for ISO R7 connections.
For ISO R228 connections, the rubber gasket provided must be fitted.
After the connection procedures, check that the connections are gas-tight with
a soap solution.
Electrical connection
When making the connection to the electrical mains, check that the voltage is the same as the value
stated on the nameplate, and that the electrical system wires are of large enough gauge to withstand
the load also stated on the nameplate.
