To turn on one of the burners, place a lighted match or
lighter near the burner, press the knob all the way in and
turn it anti-clockwise to the "High" setting.
On those models fitted with a safety device (F), the knob
must be pressed in for about 6 seconds until the device
that keeps the flame lit warms up.
On those models fitted with an ignitor, the ignition button,
identified by the
symbol, must first be pressed and
then the corresponding knob pushed all the way in and
turned anti-clockwise to the "High" setting.
Some models are equipped with an ignition button
incorporated into the control knob. If this is the case, the
ignitor is present, but not the button.
To light a burner, simply press the corresponding knob all
the way in and then turn it anti-clockwise to the "High"
setting, keeping it pressed in until the burner lights.

knob and wait for at least 1 minute before trying to relight
it.
To switch off the burner, turn the knob in a clockwise
direction until it stops (when reaches the “•” position).
Start-up and use
Practical advice on using the burners
To ensure the burners operate efficiently:
• Use appropriate cookware for each burner (see table)
so that the flames do not extend beyond the bottom of
the cookware.
• Always use cookware with a flat base and a cover.
• When the contents of the pan reach boiling point, turn
the knob to minimum.
