Cooktop
control knobs
The knobs for the gas rings are located on the front part
of the top. The symbols on the knobs have the following
meaning:
• no gas
max. gas
min. gas
Lighting the rings
To obtain the flame more easily, light the
ring before placing a recipient on the grate.
Press the knob corresponding to the ring and
turn it anticlockwise to the “max” symbol.
After lighting the flame, keep the knob pressed
for about 5 seconds; this time is necessary for
heating the “thermocouple” (Fig. 1, C) and de-
activating the safety valve, which would oth-
erwise stop the delivery of gas.
Then, make sure the flame is even and turn
the knob to the required setting.
In case of a power failure, bring a flame to
the burner and proceed as already described.
If the flame does not light after several at-
tempts, make sure the burner “cap” (fig.1, A) is
in the correct position.
To turn off the flame, turn the knob clockwise
to the symbol •.

Gas supply connection
The gas connection must be carried out in compliance
with current standards. The appliances leave the factory,
tested and adjusted for the type of gas specified on the
plate located in the bottom protection, near the gas
connection pipe. Make sure the type of gas used is the
same as that specified on the plate.
Otherwise, proceed according to the instructions given
in the section “Converting to different types of gas”.
To ensure maximum efficiency and lower consumption,
make sure the gas supply pressure respects the values
given in the “Burner specifications” table.
If the pressure of the gas used is different (or variable)
from that provided for, a suitable pressure regulator for
the piped gas (NOT LPG), complying with Standard
must be installed on the inlet piping.
The use of pressure regulators for liquified gases (LPG)
is allowed provided they comply with Standard.
The union is fitted on the end part of the gas train, with a
G 1/2" threaded nut, interposing the seal between the
components as shown in Fig.7. Screw the parts without
forcing, turn the union in the required direction, then
tighten everything.
FO 0264
Fume exhaust
Gas cooking appliances must exhaust the fumes
through hoods directly connected to flues or directly to
the outside (Fig. 5).
If a hood cannot be installed, it is necessary to use
electric exhaust fans applied to the external wall or the
window of the room, provided conditions exist so that the
opening for ventilation can be increased (see fig.6) in
proportion to the performance of the electric fan.
The electric exhaust fan performance must be able to
guarantee an hourly air exchange, for a kitchen, equal
to 3 - 5 times its volume.
Connection
Make the connection to the gas system using a rigid
metal pipe and fittings complying with Standard, or with
a s/steel flexible tube complying with Standard‘, limited
to those not longer than 2 m. When using flexible metal
tubes make sure they are not in contact with movable
parts or squashed. Pay the same attention also when
an oven and top combination is provided for.
The gas inlet union for the appliances is 1/2" cylindrical
male thread.
Make the connection, avoiding any kind of stress on the
appliance.
IMPORTANT
· After installation, always check the perfect seal of
all unions using a soapy solution. Never carry out
this check with a flame.
If the opening cannot be made in the room where the
appliance is installed, the necessary air can come from
and adjacent room, provided:
• it is not a bedroom or a dangerous environment;
• it is not in depression;
• the ventilation between the room where the appliance
is installed and the adjacent room is ensured by
means of permanent openings.

The appliance is arranged to operate on a 230 V single-
phase power supply. Connection must be made in
compliance with current standards and regulations.
Before carrying out the connection, make sure:
1) the limiter valve and the electrical system can take
the appliance load (refer to the serial no. plate);
2) the supply system is equipped with an efficient
earth connection in compliance with current
standards;
3) the socket or omnipolar switch used are easily
accessible with the appliance installed.
Fit the cable with a plug suitable for the load and connect
it to a suitable safety socket.
To connect directly to the mains, a suitable omnipolar
switch with contact gap of at least 3 mm complying with
current standards must be installed between the
appliance and the network.
The yellow/green earth wire must not be interrupted by
the switch.
The brown phase wire (coming from terminal “L” on the
terminal block) must always be connected to the power
supply phase wire.
In any case the power cable must be positioned in such
a way that no part of it reaches a temperature of more
than 90°C.
An example of an optimum path is given in Fig. 8. The
cable is guided by means of clamps fixed to the side of
the cabinet, in order to avoid any contact with the
equipment beneath the cooktop.
REPLACING THE POWER CABLE
When replacing the power cable only use H05V2V2-F
T90 type cables suitable for the load and operating tem-
perature. Also, the yellow/green earth wire must be
approx. 2 cm longer than the phase and neutral wires
(Fig. 9).
After connection, test the heating elements by operating
them for about 3 minutes.
