light in the first 15 seconds, turn the knob to
and wait 60 seconds before trying
again. After lighting, keep the knob pressed
in for a few seconds to allow the
thermocouple to heat up. The burner may
go out when the knob is released: in this
case, the thermocouple has not heated up
sufficiently. Wait a few moments and repeat
the operation. Keep the knob pressed in
longer.
In case of an accidental switching
off, a safety device will be tripped,
cutting off the gas supply, even if
the gas tap is open. Return the
knob to and wait at least 60
seconds before lighting it again.

Use
51
EN
Correct positioning of the flame-
spreader crowns and burner caps
Before lighting the hob burners, make sure
that the flame-spreader crowns are
correctly positioned in their housings with
their respective burner caps. Make sure that
the holes in the flame-spreader crowns are
aligned with the igniters and thermocouples
(A).
Practical tips for using the hob
For better burner efficiency and to minimise
gas consumption, use pans with lids and of
suitable size for the burner, so that flames
do not reach up the sides of the pan. Once
the contents come to the boil, turn down the
flame far enough to ensure that the liquid
does not boil over.
3.6 Using the oven
Switching on the oven
To switch on the oven:
1. Select the cooking function using the
function knob.
2. Select the temperature using the
temperature knob.
Functions list
Cookware diameters:
• Auxiliary: 12 - 14 cm.
• Semi-rapid: 16 - 24 cm.
• Rapid: 18 - 26 cm.
• Ultra-rapid: 18 - 28 cm.
Static
As the heat comes from above and
below at the same time, this system
is particularly suitable for certain
types of food. Traditional cooking,
also known as static cooking, is
suitable for cooking just one dish at
a time. Perfect for all types of roasts,
bread and cakes and in any case
particularly suitable for fatty meats
such as goose and duck.
Lower element
The heat coming just from the
bottom allows you to complete the
cooking of foods that require a
higher bottom temperature, without
affecting their browning. Perfect for
cakes, pies, tarts and pizzas.
Small grill + rotisserie (on some
models only)
The rotisserie works in combination
with the central grill heating element
and allows food to be perfectly
browned.

Use
52
Small grill (on some models only)
Using only the heat released from
the central element, this function
allows you to grill small portions of
meat and fish for making kebabs,
toasted sandwiches and any types
of grilled vegetable side dishes.
Grill
The heat coming from the grill
element gives perfect grilling results
above all for thin and medium
thickness meat and in combination
with the rotisserie (where fitted)
gives the food an even browning at
the end of cooking. Perfect for
sausages, spare ribs and bacon.
This function enables large
quantities of food, particularly meat,
to be grilled evenly.
Fan with grill
The air produced by the fan softens
the strong heatwave generated by
the grill, grilling perfectly even very
thick foods. Perfect for large cuts of
meat (e.g. shin of pork).
Turbo (on some models only)
The combination of fan assisted
cooking and traditional cooking
allows different foods to be cooked
on several levels extremely quickly
and efficiently, without odours and
flavours mingling. Perfect for large
volumes that call for intense
cooking.
Fan assisted (on some models
only)
The operation of the fan, combined
with traditional cooking, ensures
consistent cooking even with
complex recipes. Perfect for biscuits
and cakes, even when
simultaneously cooked on several
levels. (For multiple-level cooking,
we recommend using the 2nd and
4th shelves).
Fan + circulaire
The combination of the fan and the
circulaire heating element
(incorporated in the rear of the
oven) allows you to cook different
foods on several levels, as long as
they need the same temperatures
and same type of cooking. Hot air
circulation ensures instant and even
distribution of heat. It will be
possible, for instance, to cook fish,
vegetables and biscuits
simultaneously (on different levels)
without odours and flavours
mingling.
Defrost
Rapid defrost is helped by switching
on the fan provided and the upper
heating element that ensure uniform
distribution of low temperature air
inside the oven.

EN
3.7 Cooking advice
General advice
• Use a fan assisted function to achieve
consistent cooking at several levels.
• It is not possible to shorten cooking times
by increasing the temperature (the food
could be overcooked on the outside and
undercooked on the inside).
Advice for cooking meat
• Cooking times vary according to the
thickness and quality of the food and to
consumer taste.
• Use a meat thermometer when roasting
meat, or simply press on the roast with a
spoon. If it is hard, it is ready; if not, it
needs another few minutes cooking.
Advice for cooking with the Grill and the
Fan with grill
• Meat can be grilled even when it is put
into the cold oven or into the preheated
oven if you wish to change the effect of
the cooking.
• With the Fan with grill function, we
recommend that you preheat the oven
before grilling.
• We recommend placing the food at the
centre of the rack.
• With the Grill function, we recommend
that you turn the temperature knob to the
maximum value near the symbol to
optimise cooking.
• Foods should be seasoned before
cooking. Foods should also be coated
with oil or melted butter before cooking.
• Use the oven tray on the first bottom shelf
to collect fluids produced by grilling.
• Grilling processes should never last more
than 60 minutes.
Advice for cooking desserts/pastries and
biscuits
• Use dark metal moulds: they help to
absorb the heat better.
• The temperature and the cooking time
depend on the quality and consistency
of the dough.
• To check whether the dessert is cooked
right through: at the end of the cooking
time, put a toothpick into the highest point
of the dessert. If the dough does not stick
to the toothpick, the dessert is cooked.
• If the dessert collapses when it comes
out of the oven, on the next occasion
reduce the set temperature by about
10°C, selecting a longer cooking time if
necessary.
• While cooking desserts or vegetables,
excessive condensation may form on the
glass. In order to avoid this, open the
door very carefully a couple of times
while cooking.

Use
54
Advice for defrosting and proving
• Place frozen foods without their
packaging in a lidless container on the
first shelf of the oven.
• Avoid overlapping the food.
• To defrost meat, use the rack placed on
the second level and a tray on the first
level. In this way, the liquid from the
defrosting food drains away from the
food.
• The most delicate parts can be covered
with aluminium foil.
• For successful proving, a container of
water should be placed in the bottom of
the oven.
To save energy
• Stop cooking a few minutes before the
time normally used. Cooking will
continue for the remaining minutes with
the heat which has accumulated inside
the oven.
• Reduce any opening of the door to a
minimum to avoid heat dispersal.
• Keep the inside of the appliance clean
at all times.
