Anti-accidental turn system
on gas controls
On models without the safety sys-
tem (without the gas cut-off device), the
gas taps are equipped with a mechanical
system that prevents the controls from
being freely turned from the off position to
the on position (and, therefore, prevents
any accidental escape of gas from the bur-
ners)
if the control has not previously
been pressed down.
If at any time while using the hob
you notice that a control can be turned
from the off position without it needing
to be pressed down beforehand (for
example: due to dirt which may have
got into the gas taps and built up there)
you should, for your own safety, get
quickly in touch with technical assis-
tance in order to resolve this fault.
Safety system
components
On hobs with the safety feature (those
models which have the letters AL), the gas
cut-off device is made up of these ele-
ments:
* The safety tap
* The safety thermocouple, next to the burner
* The thermocouple-tap connection
The thermocouple sends an electric signal
to the tap which identifies whether the bur-
ner has a flame. During ignition, the tap
should be held down for at least 5
seconds, until the thermocouple has hea-
ted up and can send a satisfactory electric
signal to the tap. Should the burner go out,
the absence of a flame is detected by the
thermocouple, which makes the safety tap
cut off the flow of gas.
Using the hotplates
* When using a roasting dish, clay pots or
any utensil that reflects heat down -
wards, it is essential that the grid acces-
sory is used, for otherwise the high tem-
perature that is reflected downwards
could damage the glass or the burners.
* The grid accessory can be used when
cooking with pans that have a small
base or when a very low heat is requi-
red, for slow cooking or to keep food
warm. When it is used, the burner is less
efficient.
