Instructions for the user
6. USING THE COOKING HOB
6.1 Lighting of the cooking hob burners
Before lighting the hob burners, check that the flame-spreader crowns
are correctly in place with their respective burner caps, making sure that
the holes A in the flame-spreaders are aligned with the igniters and
thermocouples.
The supplied rack Cis for use with woks (Chinese pans).
The burner controlled by each knob is shown next to the knob. The
appliance is equipped with an electric lighting device. To light the
burners, press and turn the knob anticlockwise to the large flame symbol
until the burner lights.
On valved models, once the burner is lit, keep the knob pressed for a
few seconds to give the thermocouple time to heat up.
The burner may go out when the knob is released: this means that the
thermocouple has not warmed up enough. Wait a few moments and
repeat the operation, keeping the knob pressed for longer. This is not
necessary on burners not equipped with thermocouple. Once the burner
is lit, the flame can be adjusted as required.
Always check that the control knobs are in the (off) position when
you finish using the hob
If the burners should go out accidentally, after about 20 seconds a safety
device will be tripped, cutting off the gas supply, even if the gas tap is
open.
53

Instructions for the user
54
6.2 Practical advice for using the cooking hob burners
For better burner efficiency and to minimise gas consumption, use pans
with lids of suitable size for the burner, so that flames do not reach up
the sides of the pan (see point "6.3 Pan Diameters"). Once the contents
come to the boil, turn down the flame far enough to prevent the liquid
from boiling over. When cooking, to prevent burns or damage to the hob
all pans or griddle plates must be placed inside the perimeter of the hob.
All pans must have smooth, flat bottoms. Take the greatest care when
using fats or oils since they may catch fire if overheated. If the flame
accidentally goes out, turn off the control knob and wait at least 1 minute
before trying to re-light the burner.

7. USING THE OVENS
7.1 General warnings and advice
Before using the oven for the first time, pre-heat it to maximum
temperature (250°C) long enough to burn any manufacturing oily
residues which could give the food unpleasant odours.
The user has only to press the central key for 1 - 2 seconds to enable
use of the oven on first use or after a power blackout. To regulate, refer
to paragraph "5.2 Electronic Analogue Clock”.
During cooking, do not cover the bottom of the oven with aluminium or
tin foil, and do not place pans or trays on it; this may damage the enamel
coating. If you wish to use greaseproof paper, position it so that it does
not interfere with the hot air circulation inside the oven.
If both ovens are in use at the same time, there may be problems with
delicate cooking processes.
To prevent any steam in the oven from causing
problems, open the door in two stages: hold it
half-open (about 5 cm) for 4-5 seconds, then
open it completely. To access food, always leave
the door open for as short a time as possible to
prevent the temperature in the oven from falling
and ruining the food.
5 cm
7.2 Oven Light
It comes on when the function switch knob is turned to any position.
7.3 Cooling fan
The appliance is equipped with a cooling system, which comes into
operation as soon as a cooking function is selected. The same applies to
timed cooking operations.
Fans cause a steady outflow of air from the rear top skirt board on the
rear of the cooking hob, which may continue for a brief period of time
even after the oven has been turned off.
This ventilation system ensures that the temperatures on the outside of
the appliance meet the standards required by the current regulations.

7.4 Storage compartment
The storage drawer is at the bottom of the
cooker, underneath the oven. To open it,
pull on the top of the door. Never use it to
store flammable materials such as rags,
paper, etc.; it is intended to take the
appliance's metal accessories only.
Never open the storage compartment when the oven is on and still hot.
The temperature inside may be very high.
