Warnings

Depending on the model, your hob 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

Turn the corresponding control knob clockwise to the 0
setting.

that the safety device is no longer operating.
Keep the burner as clean as possible. If the ignition
sparkers are dirty they will not light properly. Clean them
