window or by increasing the suction power of the extractor hood (if fitted).
5
How to Use the Hob
Gas Burners
Gas flow to the burners is adjusted by turning the knobs (illustrated in fig.2) which control the valves.
Turning the knob so that the indicator line points to the symbols printed on the panel achieves the
following functions:
– Symbol
– Symbol
– Symbol
●
: Tap closed (burner off)
: High (maximum)
: Low (minimum)
– The maximum aperture position permits rapid boiling of liquids, whereas the minimum aperture position
allows slower warming of food or maintaining boiling conditions of liquids.
– To reduce the gas flow to minimum, rotate the knob further anti-clockwise to point the indicator
towards the small flame symbol.
– Other intermediate operating adjustments can be achieved by positioning the indicator between the
maximum and minimum aperture positions, and never between the maximum aperture and closed
positions.
Caution!
The cooking hob becomes very hot during operation. Keep children well out of reach.

Lighting Gas Burners
In order to light the burner, you must:
1 – Press in the corresponding knob and turn counter-clockwise (fig. 3) to the full flame position marked
by the
symbol and hold the knob in until the flame has been lit.
In the case of a mains failure light the burner with a match or lighted taper.
2 – Wait about ten seconds after the gas lighting before releasing the knob (starting time for the valve).
3 – Adjust the gas valve to the desired power.
Important
If the burner flame should go out for some reason, the safety valve will automatically stop the gas flow.
To re-light the burner, return the knob to the closed ● position, wait for at least 1 minute and then
repeat the lighting procedure.
If your local gas supply makes it difficult to light the burner with the knob set to maximum, set the knob
to minimum and repeat the operation.

Choice of Burner
The symbols printed on the panel by the side of the knob indicate which burner you are controlling.
Choose a suitable burner depending on the cookware diameter and capacity.
The pan diameter should be suitable for the burner power to make the most of the burner's high efficiency
and not waste fuel.
A small pan does not boil more quickly on a large burner (fig. 4).
