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. Just press and turn the knob
anticlockwise to the maximum flame symbol
until the burner lights.
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).
