6. USE OF THE COOKING HOB
6.1 Lighting of the cooking hob burners
Before lighting the cooking hob burners check that the flame cap crowns
are properly positioned with their appropriate burner caps: niche
A must
be centred with pin B .
Grid C should be used with Chinese woks.
Each knob corresponds to the burner indicated. The
appliance is equipped with an electronic lighting device. To
light the burners, press and turn the knob anticlockwise to
the large flame symbol. Keep the knob pressed for about 2
seconds to let the thermocouple heat up. If the burner turns
off when the knob is released, it means that the
thermocouple isn’t hot enough. Repeat ignition and keep the
knob pressed longer.
If the burners turn off accidentally, a safety device will trip after about 20
seconds to cut off gas flow (even with the gas tap open).
