Installation
The ventilation aperture must have the following
characteristics (fig.2A):
- total free cross section of passage of at least 6 cm²
for every kW of rated heating capacity of the appliance,
with a minimum of 100 cm² (the heating capacity is
indicated on the rating plate);
- it must be made in such a way that the aperture, both
on the inside and outside of the wall, cannot be
obstructed
- it must be protected, e.g. with grills, wire mesh, etc. in
such a way that the above-mentioned free section is
not reduced;
- it must be situated as near to floor level as possible.

The air inflow may also be obtained from an adjoining
room, (provided the latter is not a bedroom or a room
where there is a risk of fire, such as garages, fuel stores,
etc.) which is ventilated in compliance with the standards
in force.
Air from the adjoining room to the one to be ventilated
may be made to freely pass through permanent apertures
with a cross section at least equal to that indicated above.
These apertures may also be obtained by increasing
the gap between the door and the floor (fig.2B).
If an electric fan is used for extracting the combustion
products, the ventilation aperture must be increased in
relation to its maximum performance. The electric fan
should have a sufficient capacity to guarantee 3 to 5 air
changes an hour, ie. the fan should extract, per hour, 3
to 5 times the room volume.
Prolonged, intensive use of the appliance may require
extra ventilation, e.g. via an open window or by increasing
the extraction power of the electric fan.
Liquid petroleum gas descends towards the floor as it is
heavier than air. Apertures in the outside walls in rooms
containing LPG cylinders should therefore be at floor
level, in order to allow any gas from leaks to be expelled.
Do not store LPG cylinders (even when empty) in
basements/rooms below ground level; it is advisable to
keep only the cylinder in use in the room at any one
time and connected far from heat sources which could
raise its temperature to above 50 °C.
The following instructions are provided for qualified
installers so that they may accomplish installation,
adjustment and technical maintenance operations
correctly and in compliance with current regulations and
standards.
Important: the hob should be disconnected from the
mains electricity supply before any adjustment,
maintenance, etc. is carried out. Maximum caution
should be used whenever it is necessary to keep the
appliance connected to the electricity supply.
The hobs have the following technical characteristics:

Positioning
This appliance may only be installed and operated in
permanently ventilated rooms in compliance with
provisions laid down by current regulations and
standards. The following requirements must be observed:
Either:
• The appliance must discharge combustion products
into a special hood, which must be connected to a
chimney, flue pipe or directly to the outside (fig.1).
OR
• If it is impossible to fit a hood, the use of an electric
fan is permitted, either installed on a window or on an
external wall, which must be switched on at the same
time as the appliance.
In a chimney stack or branched flue Directly to the outside
(exclusively for cooking appliances)
Kitchen ventilation
The air flow into the room where the appliance is installed
must equal the quantity of air that is required for regular
combustion of the gas and for ventilating the same room.
Air must be taken in naturally through permanent
apertures made in the outside walls of the room or
through single or branching collective ventilation ducts
in compliance with the standards in force.
The air must be taken directly from the outside, from an
area far from sources of pollution.
