6. USE OFTHE HOB
6.1 Lighting of the hob burners
Before lighting the hob burners check that the flame caps are in the
correct position and that their burner caps are in place, making
sure that the holes A in the flame caps correspond to the spark
plugs and thermocouples.
The optional grid B must be used with “woks” (Chinese pans).
The supplied reduction rest C is used for small pans.
The drawing next to each knob shows the
corresponding burner. The appliance has an
electronic lighting device. Simply press and turn
the knob anticlockwise to the minimum flame
symbol , until the ring is lit. Hold the knob down
for a few seconds to allow the thermocouples to
heat up. The burner may go out when the knob is
released: this is because the thermocouple has
not been sufficiently heated. Repeat the
operation holding down the knob for a little
longer. This operation is not necessary for
burners without thermocouples.
For models with thermocouples, if the burner should accidentally go out,
a safety device will be activated which stops the gas flow even if the tap
is open.

Instructions for the user
6.2 Practical advice for using the hob burners
For better use of the burners and lower gas consumption, use covered
containers that are proportional in size to the burner to prevent the flame
from licking the sides (see paragraph “6.3 Diameter of containers”).
When water reaches the boiling point, lower the flame so that it doesn’t
overflow. To avoid burns or damage to the hob, all recipients or griddle
plates must be placed within the perimeter of the hob. All containers
have to have a flat and smooth bottom. When using fats or oils, be
extremely careful that they don’t overheat and catch fire.
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. USE OFTHE OVEN
For those models with electronic programmer, before using the oven
make sure that the display shows the symbol .
For those models with analogue clock and timer, place on the symbol
.
7.1 Warnings and general advice
Using the oven and the grill for the first time, heat them to the maximum
temperature (260°C) for as long as it takes to burn off any production oil
residues which could give a nasty flavour to the food. After a power cut,
the oven display will flash intermittently and show . To adjust
refer to paragraph “5.2 Electronic Programmer”.
To prevent any steam in the oven creating problems,
open the door in two stages: half open (5 cm
approx.) for 4-5 seconds and then fully open. To
access food, always leave the door open as short a
time as possible to prevent the temperature in the
oven from falling and ruining the food.
7.2 Use of the electric grill
For short cooking procedures, such as the final crisping of meat which is
already cooked, select the static grill function and turn the thermostat
knob to the maximum temperature. The fan grill function allows actual
cooking procedures to be carried out, thanks to the fan function which
ensures that the heat penetrates into the food. For this cooking mode,
select the fan grill function and turn the thermostat knob to the ideal
cooking temperature (never set at more than 220). Cooking procedures
in this mode must never last more than 60 minutes.
All cooking with the grill and grill + spit must be done with the door
closed to prevent the knobs and the front panel of the equipment to
overheat.
Failure to do this will void the warranty.
How to use the grill
Food should be flavoured and basted with oil or melted butter before cooking.
An oven dish should be used to contain the sauces. The food should be
placed on the oven shelf which is positioned on one of the guides supplied
with the different ovens, following the instructions below:

WARNING
•The oven accessories which may come into contact with food are
made from materials which conform to the standing directives.
•During and after use the accessible parts of the oven may be very hot,
and children must always be kept at a distance.
7.3 Storage compartment
A storage compartment, accessible by pulling
on the top edge of the door, is located
beneath the oven.
Never store inflammable materials such as
rags, paper or the like. The compartment is
intended only for holding the metal
accessories of the range.
