HOB BURNERS CONTROL KNOBS
The hob burners control knobs are situated on the hob
lateral panel. The symbols on the knobs mean that :
lthere is no gas supply
there is maximum gas supply
there is minimum gas supply
LIGHTING THE BURNERS
 For easier lighting, proceed before putting a pan
on the pan support.
To light a burner, push in the relevant control knob and
turn it anti-clockwise to "maximum" position.
Upon ignition, keep the knob pushed down for about 5
seconds. This will allow the "thermocouple" (Fig. 1 lett.
D) to be heated and the safety device to be switched
off, otherwise the gas supply would be interrupted.
Then, check the flame is regular and adjust it as
required.
If you cannot light the flame even after several
attempts, check the "cap" (Fig. 1 lett. ) and the
"crown" (Fig. 1 lett. B) are in the correct position.
To put the flame out, turn the knob to the symbol l.
 Always turn the flame down or put it out before
taking the pans off the burner.
USING THE HOB CORRECTLY
To ensure maximum burner efficiency, it is strongly
recommended that you use only pots and pans with a flat
bottom fitting the size of the burner used, so that flame will
not spread beyond the bottom of the vessel (see the table
beside).
It is also advisable, as soon as a liquid starts boiling, to
turn down the flame so that it will barely keep the liquid
simmering.
Carefully supervise cookings with fats or oil, since
these types of foodstuff can result in a fire, if over-
heated.

2.Cleaning and Maintenance
 Disconnect the appliance from the electrical
supply, before carrying out any cleaning or
manteinance work.
GENER L CLE NING
Wash the enamelled components with warm soapy
water. Never use abrasive cleaners
Frequently wash the "caps" and the "crowns" with hot
soapy water, carefully taking away any built-up of food.
Carefully wash the stainless steel components with
water, then wipe them dry with a soft cloth.
If the marks are particularly difficult to remove, use
common non-abrasive cleaners or specific products.
Never use steel wool pads or acids.
The electric ignition of the burners is obtained through a
ceramic "candle" and a metal electrode (fig. 1 lett. C).
Keep these components well clean, to avoid difficult
lighting, and check that the burner crown holes (lett. B)
are not obstructed.
PAN SUPPORTS
To keep the pan supports in the right position, they are
hooked to a couple of special hinges in the back of the
hob.
Thanks to these hooks, you can lift the pan supports for
easier cleaning (fig. 2). To take the pan supports
completely off the hob, proceed as shown in fig. 3.
THE HOB LID
In order to make the appliance match with the kitchen
design, a lid can be fitted on the hob.
lThe lid (not provided) is meant to avoid dust to
settle on the hob, when it is closed, and to collect
splashes of oil or fat, when it is open. Do not use
it for any other purpose.
lAlways wipe off any splash of liquid before
opening the lid.
lAlways clean the lid from cooking residues before
opening it or taking it off.
lWARNING! The crystal lid can splinter when
overheated. Always ensure all the burners are
off before closing it.

Periodically ask your local Service Centre to check the
conditions of the gas supply pipe and the pressure
adjuster, if fitted.
To ensure the good operation of the hob and its safety
features, it is necessary that the taps are periodically
lubricated.
lThe periodic lubrication of the taps must be
carried out by qualified personnel, which you
must refer to also in case of malfunctioning.

GAS CONNECTION
Choose fixed connections or use a flexible pipe in
stainless steel.
If using flexible metallic pipes, be careful they do not
come in contact with mobile parts or they are not
squeezed. Use the same attention when the hob is
combinated with an oven.
IMPORTANT - To ensure a correct operation, a saving
of energy and the long-life of the appliance, the voltage
pressure of the appliance must correspond to the
recommended values.
The adjustable connection is fixed to the comprehensive
ramp by means of a threaded nut GJ 1/2". Interpose the
sealing between the components as shown in fig. 4.
Screw the parts without forcing, adjust the connection in
the required direction and tighten everything.
IMPORTANT - When the final connection has been
made, it is essential that a thorough leak test is carried
out on the hob and installation. Use some soapy water,
never a flame.

The appliance is designed to be connected to 230 V
monophase electricity supply.
The connection must be carried out in compliance with
the laws and regulations in force.
Before the appliance is connected:
1) check that the main fuse and the domestic installation
can support the load (see the rating label);
2) check that the power supply is properly earthed in
compliance with the current rules;
3) check the socket or the double pole switch used for
the electrical connection can be easily reached with
the appliance built in the forniture unit.
The appliance is supplied with a connection cable. This
has to be provided with a proper plug, able to support the
load marked on the identification plate. To connect the
plug to the cable, follow the recommendation given in Fig.
5. The plug has to be fitted in a proper socket.
If connecting the appliance directly to the electric system,
it is necessary that you install a double pole switch
between the appliance and the electricity supply, with a
minimum gap of 3 mm. between the switch contacts and
of a type suitable for the required load in compliance with
the current rules.
The earth cable (yellow/green) must not be interrupted by
the interrupter.
The connection cable has to be placed in order that, in
each part, it cannot reach a temperature of 90 °C.
The brown coloured phase cable (fitted in the terminal
block contact marked with "L") must always be connected
to the network phase.
REPLACEMENT OF THE VOLTAGE CABLE
The connection of the voltage cable to the appliance's
terminal block is of type "Y". This means that its
replacement requires the specific equipment of a
technician.
In this case, only cable type H05V2V2-F T90 must be
used. The cable section must be suitable to the voltage
and the working temperature.
The yellow/green earth wire must be approximately 2
cm. longer than the phase wires (Fig. 5).
To open the terminal block and reach the terminals,
proceed as follows:
linsert the point of a screwdriver into the visible
protrunding part of the terminal block;
