6. USE OFTHE 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 Amust
be centred with pin B.
Grid Cshould 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).
6.2 Practical advice for using the cooking hob burners
For better use of the burners and lower gas consumption, use covered
containers that are proportional in size to the burner to prevent the flame
from licking the sides (see paragraph “6.3 Diameter of containers”).
When water reaches the boiling point, lower the flame so that it doesn’t
overflow. To avoid burns or damage to the hob, all recipients or griddle
plates must be placed within the perimeter of the cooking hob. All
containers have to have a flat and smooth bottom. When using fats or
oils, be extremely careful that they don’t overheat and catch fire.
If the flame accidentally goes out, turn off the control knob and wait at
least 1 minute before trying to re-light the burner.
