3 - USE OF THE HOB BURNERS
Caution!
The cooking hob becomes very hot
during operation.
Keep children well out of reach.
N.B. When the cooker is not being
used, set the gas knobs to their closed
positions.
GAS BURNERS
Gas ow to the burners is adjusted by
turning the knobs (illustrated in g. 3.1)
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:
- symbol 0closed valve
- symbol maximum
aperture or ow
- symbol minimum
aperture or ow
√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 ow to minimum
rotate the knob further anti-clockwise
to point the indicator towards the small
ame 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.

DEEP FAT FRYING
For safety purposes when deep fat frying,
do not ll the pan more than 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 re, leave
the pan where it is and turn off the control
knobs.
Place a damp cloth or lid over the pan to
smother the ames. Leave the pan to cool
for at least 30minutes before moving the
pan.
DO NOT USE WATER ON THE FIRE.
CHOICE OF THE BURNER
On the control panel, near every knob
there is a diagram that indicates which
burner is controlled by that knob.
The suitable burner must be chosen
according to the diameter and the capacity
used.
As an indication, the burners and the pots
must be used in the following way:
DIAMETERS OF PANS WHICH MAY BE
USED ON THE BURNERS
BURNERS MINIMUM MAXIMUM
Auxiliary 12 cm 14 cm
Semi-rapid 16 cm 24 cm
Rapid 24 cm 26 cm
Triple-ring 26 cm 28 cm
do not use pans with concave or convex
bases
Fig. 3.3
It is important that the diameter of the pot
be suitable to the potentiality of the burner
so as not to compromise the high output
of the burners and therefore energy waste.
A small pot on a large burner does not give
you a boiling point in a shorter amount of
time since the capacity of heat absorption
of a liquid mass depends on the volume
and the surface of the pot.
LIGHTING THE BURNERS
To ignite the burner, the following
instructions are to be followed:
1. Press in the corresponding knob and
turn counter-clockwise (g. 3.2) to the
full ame position marked by the
symbol (g. 3.1); hold the knob in unt il
the ame has been lit.
In the case of a mains failure light the
burner with a match or lighted taper.
2. Wait for a few seconds after the gas
burner has been lit before letting
go of
the knob (valve activation delay).
3. Adjust the gas valve to the desired
position.
If the burner ame should go out for some
reason, the safety valve will automatically
stop the gas ow.
To re-light the burner, return the knob to
the closed 0position, wait for at least
1 minute and then repeat the lighting
procedure.
If your local gas supply makes it difcult
to light the burner with the knob set to
maximum, set the knob to minimum and
repeat the operation.
