Switching on 
automatically

If your cooktop can be switched on automatically (ignition 
sparkers):

1. Press the chosen burner control knob and turn it 
anticlockwise to the maximum power setting.
While the control knob is still pressed down, sparks are 
produced on all burners. The flame ignites (it is no longer 
necessary to press down the control knob).

2. Turn the control knob to the required setting.

If it does not come on, turn the control knob to the off 
setting and repeat the steps above. This time, press and 
hold the control knob for longer (up to 10 seconds).

Warning! If after 15 seconds the flame does not ignite, 
switch off the burner and open a nearby window or door. 
Wait at least one minute before trying to switch the burner 
on.

Safety system

Depending on the model, your cooktop may have a 
safety system (thermocouple) that prevents the flow of 
gas if the burners accidentally switch off. To ensure that 
this device is active, switch on the burner as usual and, 
without releasing the control knob, press and hold it 
down firmly for 4 seconds after lighting the flame. Fig. 15.

Switching off a burner

Turn the corresponding control knob clockwise to the 0 
setting.

Power levels

The progressive control knobs can be used to control the 
power needed, from minimum to maximum power.
