Pursuant to Directives 2002/95/EC, 2002/96/EC and 2003/108/EC relating to
the reduction of the use of hazardous substances in electrical and electronic
appliances, as well as to the disposal of refuse, the crossed out bin symbol on
the appliance indicates that the product, at the end of its useful life, must be
collected separately from other refuse. Therefore, the user must consign the
product that has reached the end of its working life to the appropriate selective
collection centres for electrical and electronic refuse, or deliver it back to the
retailer when purchasing an equivalent product, on a one for one basis.
Adequate selective collection for the subsequent forwarding of the
decommissioned product to recycling, treatment and ecologically compatible
disposal contributes to avoiding possible negative effects on the environment
and on health and promotes the recycling of the materials of which the
appliance consists. The illicit disposal of the product by the user results in the
application of administrative sanctions.
The product does not contain substances in quantities sufficient to be
considered hazardous to health and the environment, in accordance with
current European directives.
3.2 Your environmental care
Our product's packaging is made of non-polluting materials, therefore
compatible with the environment and recyclable. Please help by disposing of the
packaging correctly. You can obtain the addresses of collection, recycling and
disposal centres from your retailer or from the competent local organisations.
Do not discard the packaging or any part of it, or leave it unattended. It can
constitute a suffocation hazard for children, especially the plastic bags.
Your old appliance also needs to be disposed of correctly.
Important: hand over your appliance to the local agency authorised for the
collection of household appliances no longer in use. Correct disposal enables
intelligent recovery of valuable materials.
Before disposing of your appliance it is important to remove doors and leave

8. USING THE COOKING HOB
8.1 Lighting the 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.
Before lighting the burners, lift the glass lid (optional, not provided as
standard); before closing it again, turn off all burners and wait for them to cool.
The optional pan stand B is for use with woks.
To avoid deterioration of the hob, the cooker comes complete with a raised pan
stand Cfor use underneath pans more than 26 cm in diameter.
The reduction C supplied is for use with small pans as well.
The burner controlled by each knob is shown next to the knob.
The appliance is equipped with an electronic ignition device.
Simply press the knob and turn it anti-clockwise to the
maximum flame symbol , until the burner lights. If it does
not light in the first 15 seconds, position the knob on and
wait at least 60 seconds before trying to light it again.
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: in this case, the thermocouple has not heated up
sufficiently.
Wait a few moments and repeat the operation keeping the knob pressed for
longer. This is not necessary on burners that are not equipped with a
thermocouple.
On models with a thermocouple, if the burners should go out accidentally, a
safety device will be tripped, cutting off the gas supply even if the gas tap is
open. In this case, turn the knob to the OFF position and wait at least 60
seconds before trying to light the burner again.

Instructions for the user
58
8.2 Practical hints for using the hob burners
For better burner efficiency and to minimise gas consumption: use pans with lids
and of a suitable size for the burner, so that the flames do not reach up the sides
of the pan (see paragraph “8.3 Pan diameters”). Once the contents come to the
boil, turn down the flame far enough to ensure that the liquid does not boil over.
To prevent burns or damage to the hob during cooking, all pans or griddles 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.

9. USING THE OVEN
9.1 Before using the appliance
Remove any labels (apart from the technical data plate) from trays, dripping
pans and the cooking compartment.
Remove any protective film from the outside or inside of the appliance, including
from accessories such as trays, dripping pans, the pizza plate or the base
cover.
Before using the appliance for the first time, remove all accessories from the
oven compartment and wash them as indicated in “11. CLEANING AND
MAINTENANCE”.
Heat the empty appliance to the maximum temperature in order to remove
any manufacturing residues which could affect the food with unpleasant odours.
9.2 General Description
9.2.1 Oven runners
The oven features 5 runners for positioning
trays and racks at different heights. The insertion
heights are numbered from the bottom upwards
(see figure).
9.2.2 Oven inside lights
The oven light comes on every time the oven door is opened or when any
function is set using the function selector knob. See “12.1 Replacing the light
bulb” for instructions on replacing the oven light.

Instructions for the user
60
9.3 General warnings and advice for use
All cooking operations must be carried out with the door closed.
During cooking, do not cover the bottom of the oven with aluminium or tin foil
and do not place pans or oven trays on it as this may damage the enamel
coating. If you wish to use greaseproof paper, place it so that it will not interfere
with the hot air circulation inside the oven.
For the best cooking results, we recommend
placing cookware in the centre of the rack.
To prevent any steam in the oven from causing
problems, open the door in two stages: keep it
half open (5 cm approx.) for 4-5 seconds and
then fully open. If you need to access the 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.
To prevent excessive amounts of condensation
from forming on the internal glass, hot food
should not be left inside the oven for too long
after cooking.
9.4 Tangential cooling system
This system keeps the door and internal components of the oven at a lower
temperature through forced recirculation of cool air, guaranteeing increased
safety and a longer life for the household appliance.
The tangential cooling system remains active even after cooking has finished
and continues working when the oven has been switched off in order to disperse
all the heat that has built up inside. This mechanism allows all the furniture units
surrounding the appliance to be protected, preventing them from overheating.

Instructions for the user
61
9.5 Using the electric grill
9.5.1 Using the grill in cookers with an electric oven
For short cooking processes, such as final browning of cooked meat, select the
static grill function and turn the thermostat knob to the maximum
temperature setting. The fan-assisted grill function (on some models only)
allows real cooking processes to be carried out, thanks to the forced fan system
that ensures the heat penetrates inside the food. For this type of cooking
operation, select the fan-assisted grill function and use the thermostat knob
to set the ideal cooking temperature (in all cases no more than 200°C).
9.5.2 How to use the grill
When the oven has come on, confirmed by the red light switching on, leave it to
heat up for 5 minutes before placing foods inside.
Food must be seasoned before cooking. Foods should also be coated with oil or
melted butter before cooking. Use the oven tray to collect juice.
The foods to cook must be placed on the oven rack, which must then be placed
on one of the runners fitted in the various types of ovens, following the
guidelines below:
FOOD RACK ON
SHELF
Flat, thin pieces of meat 3
Rolled roasts 2 - 3
Poultry 2 - 3

Instructions for the user
62
PRECAUTIONS
• Grilling processes must never last more than 60 minutes.
• In models with an electric oven, the oven door must be closed during grill
cooking operations.
• To prevent hazardous overheating, the appliance's glass lid (optional, not
provided as standard) must always be raised when using the oven or grill.
• Accessible parts may be very hot during and after use of the grill; keep
children well away from the appliance.
• When using the oven, remove all unused trays and racks from its interior.
• During cooking, do not cover the bottom of the oven with aluminium or tin foil
and do not place pans or oven trays on it as 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.

10.COOKING WITH THE OVEN
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 or thermal radiation
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.
BOTTOM:
The heat coming solely from the bottom makes it possible to
complete the cooking of foods that require a greater basic
temperature, without affecting their browning. Perfect for cakes,
pies, tarts and pizzas.
SMALL GRILL:
Using only the heat released from the central heating element,
this function allows to grill small portions of meat and fish for
making kebabs, toasted sandwiches and all types of grilled
vegetable side dishes.
GRILL:
The heat coming from the grill element gives perfect grilling
results, especially for thin and medium thickness meat and, in
combination with the rotisserie (when present), it allows the
food to be browned evenly at the end of cooking. Perfect for
sausages, ribs and bacon. This function enables large
quantities of food, particularly meat, to be grilled evenly.
FAN-ASSISTED GRILL:
The air produced by the fan softens the strong heatwave
generated by the grill, giving perfect grilling results even with
very thick foods. Perfect for large cuts of meat (e.g. shin of
pork).
TURBO:
The combination of fan-assisted cooking and traditional cooking
enables different foods to be cooked on several levels extremely
quickly and efficiently, without any transfer of odours and
flavours. Perfect for large volumes that call for intense cooking.
(For multiple-level cooking, we recommend using the 2nd and
4th runners.)

Instructions for the user
64
CIRCULAR:
The combination of the fan and the circular element
(incorporated in the rear of the oven) enables different foods to
be cooked on several levels, as long as they need the same
temperature and same type of cooking operation. Hot air
circulation ensures instant and uniform distribution of heat. It will
be possible, for instance, to cook fish, vegetables and biscuits simultaneously
(on different levels) without mixing odours and flavours.
(For multiple-level cooking, we recommend using the 2nd and 4th runners.)
DEFROSTING: (on the multifunction model only)
Rapid defrosting is helped by switching on the fan and the top
heating element to ensure uniform distribution of low-
temperature air inside the oven.
10.1 Cooking advice and instructions
10.1.1 General advice
We recommend preheating the oven before putting food in.
• For cooking on several levels, we recommend using a fan-assisted function
to achieve uniform cooking at all heights.
• In general, it is not possible to shorten cooking times by increasing the
temperature (the food could be well-cooked on the outside and undercooked
on the inside).
10.1.2 Advice for cooking meat
• Cooking times, especially for meat, vary according to the thickness and
quality of the food and to consumer taste.
• We recommend using a meat thermometer for meat when roasting it.
Alternatively, simply press on the roast with a spoon: if it is hard, it is ready; if
not, it needs another few minutes' cooking.
10.1.3 Advice for cooking desserts and biscuits
• Use dark metal moulds for desserts: they help to absorb the heat better.
• The temperature and the cooking time depend on the quality and
consistency of the dough.
• Check whether the dessert is cooked all the way 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.
