How to use the hob burners

Hob burners

Each hob burner is controlled by a
separate gas tap operated by a control
knob (fig. 5) which has 3 positions marked
on the control panel, these are:

– Symbol ● : tap closed (burner off)

– Symbol : High (maximum)

– Symbol : Low (minimum)

Push in and turn the knob anti-clockwise
to the selected position.

Lighting of the hob burners

To ignite the burner, the following instructions are to be followed:

1) Lightly press and turn the knob anti-clockwise, and position the knob indicator to the

symbol printed on the control panel (fig. 5).

2) Press the knob to operate the electric ignition; or, in the case of a mains failure light the
burner with a match or lighted taper.

3) Adjust the burner according to the setting required.

Low High

To turn the burner off, fully rotate the knob clockwise to the off position: ●.
The maximum setting of the control tap is for boiling, the minimum setting is for slow

cooking and simmering.
All working positions must be choosen between the maximum and minimum setting, never

between the maximum setting and the “OFF” position.

Fig. 5

Electric ignition

The sparks generated by the electrodes close to the burners will ignite the choosen
burner. Whenever the lighting of the burners is difficult due to peculiar conditions of
the gas features or supply, it is advised to repeat the ignition with the knob on
“minimum” position.

Burners Pan diameter

Auxiliary 12 ÷ 14 cm
Semi-rapid 16 ÷ 24 cm
Rapid 24 ÷ 24 cm
Triple-ring 26 ÷ 28 cm

do not use pans with concave or convex bases

Fig. 6a

Choice of burner

The burner must be choosen according to the diameter of the pans and energy required.

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.

How to use the gas oven

Lighting the oven gas burner

The thermostat allows the automatic control of the temperature.
The gas delivery to the oven burner is controlled by a two way thermostatic tap (oven
and grill burners) with flame-failure device.

To light the oven burner operate as follow:

1) Open the oven door

2) Lightly press and turn the thermostat knob anti-clockwise to max position “ ”.

3) Press the knob right down to prime the electric ignition.

WARNING: Risk of explosion!

The oven door must be open during this operation.

In case of power cut, press the knob and immediately approach a lighted match to the
opening “A” (fig. 8). Never continue this operation for more than 15 seconds. If the

burner has still not ignited, wait for about 1 minute prior to repeating the ignition.

4) Wait about 10/15 seconds after the burner lighting before releasing the knob (time of priming
of the valve).

5) Close the oven door slowly and adjust the burner
according to the power required.

Should the flame of the burner estinguish
for any reason, the safety valve will cut off
automatically the gas flow to the tap.
To re-start operation, take the knob to “off”
position, wait for at least 1 minute and
repeat operations as above explained.

Oven thermostat

The oven thermostat (fig. 9) is marked with
numbers, these correspond to the oven
temperature, in addition the “OFF” position is
shown by the
symbol ●.

To choose the
required oven
temperature (check
with the “Oven
cooking
temperatures”), turn
the control knob until
its line mark is level
with the number
required on the
control panel (facia).
