Dear customer,
Congratulations on your choice and thank you for purchasing one of our appliances. This
practical, modern and functional appliance is manufactured using materials of the highest
quality which are subject to strict quality control checks throughout the entire manufacturing
process. The appliance is meticulously tested to ensure that it meets your demands and
produces perfect cooking results.
Do not remove the appliance from its protective packaging until it is installed in the unit.
Please read these instructions carefully before proceeding to install and use the appliance.
The information contained in these instructions is essential for the correct operation of the
appliance and, more importantly, for your safety.
The packaging of your appliance has been manufactured using only the materials which are
strictly necessary to guarantee efficient protection during transport.
These materials are 100% recyclable, thus reducing the environmental impact. You can also
contribute to caring for the environment, by following the advice below:
- dispose of the packaging in the appropriate recycling bin
- before you get rid of an old appliance, make sure you disable it. Contact your local authority
to find out the address of your nearest recycling centre to dispose of your appliance
- do not pour used oil down the sink. Collect it in a sealed container and take it to an
appropriate collection point or, failing that, place it in the rubbish bin (it will end up in a
controlled dump; this is probably not the best option, but it will avoid contaminating ground
water)
IMPORTANT:
In the unlikely event that the appliance should be damaged or not meet your expectations
in terms of quality, please inform us as soon as possible. For the warranty to be valid, the
appliance must not have been tampered with, or used inappropriately.

Operation
The appliance has been factory adjusted so that the first
time it is connected the childproof lock is automatically
activated. To deactivate the childproof lock, keep the
"child blocker" switch pressed down several seconds
until the main switch’s light comes on. The hob is now
ready for use.
In case of a power failure or voltage drop, the childproof
lock will be automatically activated when switching on the
appliance again.
There are indications to show which burner each control
knob operates. Fig. 1.
It is essential to ensure that all the burner parts and the
pan supports are correctly installed for the appliance to
work correctly. Fig. 2-3-4.
To turn on a burner Connect the appliance by means of the main switch, its
indicator which will come on. Then turn the chosen
burner control to the left (anticlockwise) to the required
position. The flame will automatically and the hotplate
indicator light will come on.
If the main switch has been pushed but no burner
ignited, the appliance will switch itself off automatically
after 3 minutes.
If the burner goes out (e.g. a draught) when in use, the
appliance will switch the hotplate on again automatically.
If this ignition is unsuccessful (e.g. as a result of
boiled-over liquid on the burner), the flow of gas to this

burner is interrupted and the hotplate indicator flashes.
Turn the control knob to 0 and check whether the cause
can be rectified using the table on page 16.
Safety system The hob is equipped with an electronic safety system
(thermocouple) that cuts off the gas when the burners are
accidentally switched off. To ensure that this device is
active, switch on the burner as usual.
Every hotplate features a safety pilot!
This means that if the flame ever goes out (e.g. is
extinguished by boiled-over liquid), the flow of gas is
interrupted.
To turn the burners off After finishing cooking, turn the controls to position 0 and
disconnect the appliance using the main switch.
The main switch indicator will be turned off.
Please note The appliance switches off automatically after 6 hours of
operation. Turn all the control knobs to the 0 position and
then you can turn the appliance on again.
Power levels The progressive control knobs can be used to control the
power needed, from minimum to maximum power.

For dual double-flame burners, the inner and outer

The available power levels are as follows:

“Power on/off” and
residual heat indicator
Every cooking zone is fitted with a “power on/off” and
residual heat indicator which comes on when the flame
on the corresponding burner is ignited.
The residual heat indicator remains on after the cooking
zone has been switched off provided the hotplate is still
hot enough to be dangerous when touched.
The residual heat indicator goes out when the hotplate
has cooled sufficiently.
Overheating
protection
The hob is equipped with overheating protection to
protect the electronics. This switches all the burners off
in the event of overheating and the “power on/off”
indicators in all the burners and the main switch flash.
Turn all control knobs to the 0 position. Wait until the
appliance has cooled down sufficiently and the power
on/off indicator for the main switch has gone out.
Now you can switch on the appliance as usual.
The burner power on/off indicators stop flashing rapidly
or switch over to the residual heat indicator.
Childproof locks To activate the childproof lock, disconnect the hob by
means of the main switch, then press on the child lock
for a few seconds until the child lock indicator comes
on. The hob cannot then be switched on.
To deactivate the childproof lock, press on the child lock
for a few seconds until the main switch indicator comes
on. The hob can then be switched on as usual.
Warnings This appliance will not function if it is not connected to the
mains electricity or if the electricity supply is interrupted.
It is normal to hear a slight whistling noise while the
burner is operating.
When it is first used, it is normal for the burner to give off
odours; this does not pose any risk and does not indicate
a malfunction; they will disappear in time.
A few seconds after switching off the burner, it will make
a sound (thud). This is not a fault - this means that the
safety device is no longer operating.
Inner flame on full power.
Inner flame on minimum power.

Keep the burner as clean as possible. If the ignition
sparkers are dirty they will not light properly. Clean them
periodically using a small non-wire brush. Bear in mind
that the ignition sparkers must not suffer any serious
impacts.
An orange-coloured flame is normal. This is caused by
the presence of dust in the atmosphere, spilt liquids, etc.
The kitchen will become hot and humid when this gas
appliance is used. You must therefore ensure that the
kitchen is well ventilated:
either keep the natural ventilation apertures open, or
install a ventilation system (extractor hood).
If using the appliance intensively for prolonged periods,
you may require additional ventilation (e.g. by opening a
window) or more effective ventilation (e.g. by increasing
the hob's ventilation, if possible).
If the burner flames are accidentally blown out, switch off
the burner operating control knob and do not try to relight
it for at least one minute.
Suitable pans
Wok pan A wok is a cooking vessel originating in China; it is a kind
of deep, round, lightweight pan with handles and a flat or
concave base.
Food can be prepared in various ways in a wok: it can be
stewed, stir fried, cooked on a low heat, pan-fried or
steamed. It could be said that woks serve as both as a
saucepan and a frying pan and, owing to their shape and
size, they can be used to cook quite large ingredients.
When cooking with a wok, heat is diffused more uniformly
and gently; the intense heat which accumulates means
that food takes less time to cook and also requires less
oil, making it one of the quickest and healthiest ways of
cooking.
Always follow the manufacturer's instructions when
cooking with a wok pan.
