How the hob works
The gas burners have different sizes and
capacities. Select the burner most appro-
priate to the size of the pan to be used.
The burner selected can be regulated as
follows using the appropriate knob ( M ):
Regulator closed
Maximum
Minimum
The symbols next to the knobs indi-
cate the position of the gas burner select-ed
on the hob.
Only on certain models
The gas burners are equipped with a ther-
mocouple safety device to prevent gas
from leaking out. This device ensures that
the gas supply is shut off if the flame on the
gas burner is extinguished while the burner
is in use.

Igniting the gas burners

Proceed as follows to light one of the
burners:
• Turn the appropriate knob anti-clockwise
to the large flame symbol;
• Press in the knob firmly to activate the
automatic gas igniter
• Hold the knob in for around 10 seconds
once the flame has ignited to allow the
thermocouple to heat up.
• Then release the control knob and ensure
that the gas has ignited properly. If it has
not, repeat the process.
To set the burner to minimum capacity, turn
the knob to the small flame symbol. It is
also possible to make intermediate settings
by turning the knob to points between the
large and small flames.
To switch off the burner, turn the knob
clockwise to the " ● " OFF position.

Operating instructions

●
Important:
• Do not operate the automatic gas igniter
continuously for longer than 15 seconds.
• In some cases, problems with ignition can
be traced back to air in the gas pipes.
• If the flame should unexpectedly go out,
gas will continue to leak out for a short
while until the thermal safety device cuts
in. Turn the control knob to " ● " OFF and
wait for at least 1 minute before trying to
ignite the flame again. This gives the
leaked gas time to disperse.
• If the cooker is not being used, check that
the control knobs are in the " ● " OFF posi-
tion. We also recommend that you close
the main gas tap.
Cooling fan
In order to reduce the surface tempera-
tures, the appliance is equipped with a tan-
gential cooling fan, which is activated auto-
matically when the oven is warm.

Practical advice on using the burners

To use the burners to their full, we recom-
mend that you only use pans of a suitable
size for the burner to be used. This pre-
vents the flame from extending beyond the
base of the pan (see the table below).
It is further recommended that once the
food has been brought to the boil, the flame
is reduced for the remainder of the boiling
process.
