How to use your gas hob

GAS BURNERS
Gas flow to the burners is adjusted by turning the knob illustrated in fig. 2 which con-
trols 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
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, not between the maximum
aperture and closed positions.
To switch off, turn the knob clockwise to the off position.
Note: If you are using a burner at the minimum setting, you turn the knob clockwise
past the maximum setting before reaching the off position.

LIGHTING OF BURNERS
To ignite the burners follow these instructions:
– Lightly press the knob (fig. 3) in an anti-clockwise direction up to the maximum
aperture (symbol ); press the knob right down to prime the electric ignition
until the burner lights.
In case of power cut manually light the burner.
– Adjust the burner according to the power required.
If the burner fails to ignite repeat the ignition with the knob on “minimum” position.

Auxiliary 6 cm 14 cm
Medium-speed 16 cm 20 cm
Rapid 20 cm 24 cm
do not use pans with concave or convex bases
CHOICE OF BURNER
The burner must be choosen according to the diameter of the pans and energy required.
Attention: During use the hob becomes very hot under the cooking zones.
Keep children away.
Figure 4
Saucepans with handles which are excessively heavy, in relationship to the weight of the
pan, are safer as they are less likely to tip.
Pans which are positioned centrally on burners are more stable than those which are
offset.
It is far safer to position the pan handles in such a way that they cannot be accidentally
knocked.
When deep fat frying fill the pan only one third full of oil.
DO NOT cover the pan with a lid and DO NOT leave the pan unattended.
In the unfortunate event of a fire, leave the pan where it is and turn off all controls.
Place a damp cloth or correct fitting lid over the pan to smother the flames.
DO NOT use water on the fire.
Leave the pan to cool for at least 30 minutes.
