GAS COOKING HOBS
GAS BURNERS
Gas flow to the burners is adjusted by turning the knobs (illustrated in figs. 2.1a - 2.1b) which control the safety valves.
Turning the knob so that the indicator line points to the symbols printed on the panel achieves the following functions:
✓ full circle | ● = | closed valve |
✓ symbol | = | maximum aperture or flow |
✓ symbol | = minimum aperture or flow | |
To light one of the gas burners, hold a flame (e.g. a match) close to the top part of the burner, push in and turn the relative knob in an
To reduce the gas flow to minimum, rotate the knob further
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.
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.
N.B. When the cooker top is not being used, set the gas knobs to their closed posi- tions and also close the cock valve on the gas bottle or the main gas supply line.
VALVELESS ELECTRIC SPARK-LIGHTING GAS BURNERS
Models fitted with electric spark lighter button
On these cooker tops, to light one of the burners you have to push in and turn the rela- tive knob to the maximum aperture position (large flame symbol) and press the electric lighter button (fig. 2.2) until the flame has been lit.
Adjust the gas valve to the desired position.

symbol (max. heat/max. gas flow) (fig. 2.1b).
To light one of the gas burners, push in and turn the relative knob to the maximum aperture position (large flame symbol) and hold the knob in until the flame has been lit. The sparks produced by the lighter situated inside the relative burner will light the flame.
In the event that the local gas supply conditions makes it difficult to light the burner in maximum aperture position, try again with the knob in minimum position.
LIGHTING GAS BURNERS FITTED WITH SAFETY VALVE DEVICE
In order to light the burner, you must:
1 – Turn the knob in an
In models with the gas lighter incorporated in the knob, this will light the gas. If there is no mains electrical supply, bring a lighted match close to the burner.
2 – For models with
3 – Wait about ten seconds after the gaslights before releasing the knob (starting time for the valve).
4 – Adjust the gas valve to the desired position.
If the burner flame should go out for some reason, the safety valve will automatically stop the gas flow.
