'Burner in operation' indicator
Control indicator
Off position
Maximum gas position
Minimum gas position
Burner on position
The device shall not be operated
for more than 15 seconds. If after 15
seconds the burner has not lit, stop the
device and open the compartment door
and/or wait at least 1 minute before
attemting a futher ignition of the burner.
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-
fig. 9
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.
