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 appliance should be disconnected from
the mains electricity supply before any adjustment,
maintenance, etc. is carried out. Maximum caution should
be used should it be necessary to keep the appliance
connected to the electricity supply. The cookers have the
following technical specifications:
Category: II 2H3+
Class: 1
The dimensions of the appliance are given in the figure on
page 2. For trouble-free operation of appliances installed in
housing units, the minimum distances shown in fig.4 should
be observed. Adjacent surfaces and the wall at the rear
should also be able to withstand an overheating temperature
of 65 °C. Prior to installing the cooker, 95 ÷ 155 mm high
supporting feet (provided) should be fitted into the holes to
be found in the bottom of the cooker (fig.5). These feet are
screw-adjustable and whenever necessary should be used
to make sure the cooker stands level.
Positioning
This appliance may only be installed and operated in
permanently ventilated rooms in compliance with current
standards. The following requirements must be observed:
• 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.6).
• 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.

INSTALLATION
fig.6
Directly to the outside
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
current standards and regulations. The air must be taken
directly from the outside, from an area far from sources of
pollution. The ventilation aperture must have the following
characteristics (fig.7A):
• 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 grates, 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 warehouses, garages, fuel stores,
etc. and is ventilated in compliance with the current
standards and regulations. Air from the adjoining room to
the one to be ventilated may be made to pass freely 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.7B).
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 an hourly exchange
of air equal to 3 ÷ 5 times the volume of the kitchen.
Prolonged, intensive use of the appliance may require extra
ventilation, e.g. an open window or a more efficient
ventilation system by increasing the extraction power of
the electric fan if installed. 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 or 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.
