How to use the hob burners
Hob burners
Each hob burner is controlled by a
separate gas tap operated by a control
knob (fig. 5) which has 3 positions marked
on the control panel, these are:
– Symbol
● : tap closed (burner off)
– Symbol
: High (maximum)
– Symbol
: Low (minimum)
Push in and turn the knob anti-clockwise
to the selected position.
Low
Fig. 5
High
To turn the burner off, fully rotate the knob clockwise to the off position: ●.
The maximum setting of the control tap is for boiling, the minimum setting is for slow
cooking and simmering.
All working positions must be choosen between the maximum and minimum setting, never
between the maximum setting and the “OFF” position.
Electric ignition
The sparks generated by the electrodes close to the burners will ignite the choosen
burner. Whenever the lighting of the burners is difficult due to peculiar conditions of
the gas features or supply, it is advised to repeat the ignition with the knob on
“minimum” position.
Lighting of the hob burners
To ignite the burner, the following instructions are to be followed:
1) Lightly press and turn the knob anti-clockwise, and position the knob indicator to the
symbol
printed on the control panel (fig. 5).
2) Press the knob to operate the electric ignition; or, in the case of a mains failure light the
burner with a match or lighted taper.
3) Adjust the burner according to the setting required.
8
Choice of burner
The burner must be choosen according to the diameter of the pans and energy required.
Burners
Pan diameter
Auxiliary
12 ÷ 14 cm
Semi-rapid
16 ÷ 24 cm
Rapid
24 ÷ 24 cm
Triple-ring

Fig. 6
do not use pans with concave or convexe bases
Saucepans with handles which are excessively heavy, in relationship to the weight of the
pan, are safer as they are less likely to tip.
Pans which are positioned centrally on burners are more stable than those which are offset.
It is far safer to position the pan handles in such a way that they cannot be accidentally
knocked.
When deep fat frying fill the pan only 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 fire, leave the pan where it is and turn off all controls.
Place a damp cloth or correct fitting lid over the pan to smother the flames.
DO NOT use water on the fire.
Leave the pan to cool for at least 30 minutes.

How to use the Multifunction oven
Operating principles
Heating and cooking in the MULTI-FUNCTION oven are obtained in the following ways:
a. by normal convection
The heat is produced by the upper and lower heating elements.
b. by forced convection
A fan sucks in the air contained in the oven muffle, which sends it through the circular
heating element and then sends it back through the muffle. Before the hot air is
sucked back again by the fan to repeat the described cycle, it envelops the food in
the oven, provoking a complete and rapid cooking.
It is possible to cook several dishes simultaneously.
c. by semi-forced convection
The heat produced by the upper and lower heating elements is distributed
throughout the oven by the fan.
d. by radiation
The heat is radiated by the infra red grill element.
e. by radiation and ventilation
The irradiated heat from the infra red grill element is distributed throughout the oven
by the fan.
Please note: This appliance incorporates a safety cooling fan which you will hear
operating whenever the oven or grill are in use. This fan is to reduce the external
temperature of the appliance and cool the internal components.

FUNCTION SELECTOR KNOB
THERMOSTAT KNOB (Fig. 8)
(Fig. 7)
Rotate the knob clockwise to set the oven
for one of the following functions.
This only sets the cooking temperature and
does not switch the oven on. Rotate
clockwise until the required temperature is
reached (from 50 to 225°C).
11
OVEN LIGHT
By setting the knob to this position, only the oven light comes on (15 W).
It remains on in all the cooking modes.
TRADITIONAL CONVECTION COOKING
The upper and lower heating elements come on. The heat is dispersed by natural
convection and the temperature must be set to between 50° and 225°C via the
thermostat knob.
The oven must be preheated before cooking.
Recommended for:
Food that requires the same degree of cooking both inside and out, for example roasts,
spare pork ribs, meringues etc.
GRILLING
The infrared grill element comes on. The heat is dispersed by radiation.
Set the thermostat knob to between 50° and 200°C.
Always grill with the oven door closed.
For cooking hints, see the chapter “USE OF THE GRILL”.
Recommended for:
Intense grilling, browning, cooking au gratin and toasting etc.
Do not grill for longer than 30 minutes at any one time on full heat (200°C).
Caution: the oven door becomes very hot during operation.
Keep children well out of reach.
DEFROSTING FROZEN FOODS
Only the oven fan comes on. Use with the thermostat knob set to “●” - other positions
have no effect. The food is thawed by ventilation without heating.
Recommended for:
Quick thawing of frozen foods; one kg requires approximately 1 hour.
Thawing times vary according to the quantity and type of food to be thawed.
12
HOT AIR COOKING
The circular element and fan come on. The heat is dispersed by forced convection
and the temperature can be regulated to between 50° and 225°C via the
thermostat knob. The oven does not require preheating.
Recommended for:
Food which has to be well-cooked outside and soft or rosy inside, for example
lasagne, lamb, roast beef, whole fish etc.
VENTILATED GRILL COOKING
The infrared grill element and the fan come on. The heat is dispersed mainly by
radiation and the fan then distributes it all over the oven.
Use with the door closed. The temperature can be regulated via the
thermostat knob to between 50° and 175° max.
The oven must be preheated for approximately 5 minutes. For cooking hints, see
the chapter “GRILLING AND COOKING AU GRATIN.
Recommended for:
Grilling where quick browning on the outside is required to keep the juices in.
For example: veal steaks, chops, hamburgers etc.
Do not grill for longer than 30 minutes at any one time on full heat (175°C).
Caution: the oven door becomes very hot during operation.
Keep children well out of reach.
MAINTAINING TEMPERATURE AFTER COOKING OR
SLOWLY HEATING FOODS
The upper heating element, the circular element and the fan come on.
The heat is dispersed by forced convection with greater intensity in the upper part.
The temperature can be set to between 50° and 140°C via the thermostat knob.
Recommended for:
Keeping food warm after any type of cooking. Slow heating of cooked food.
CONVECTION COOKING WITH VENTILATION
The upper and lower heating elements come on and the fan.
The heat coming from above and below is dispersed by convection with ventilation.
The temperature can be set to between 50° and 225°C via the thermostat knob.
Recommended for:
Voluminous dishes and large quantities which require the same degree of cooking
both inside and out, for example rolled roasts, turkey, roast legs, cakes etc.
13
COOKING ADVICE
STERILIZATION
Sterilization of foods to be conserved, in full and hermetically sealed jars, is done in the
following way:
a. Set the switch to position
.
b. Set the thermostat knob to position 185 °C and preheat the oven.
c. Fill the dripping pan with hot water.
d. Set the jars onto the dripping pan making sure they do not touch each other and
the door and set the thermostat knob to position 135 °C.
When sterilization has begun, that is, when the contents of the jars start to bubble,
turn off the oven and let cool.
REGENERATION
Set the switch to position
and the thermostat knob to position 150° C.
Bread becomes fragrant again if wet with a few drops of water and put into the oven
for about 10 minutes at the highest temperature.
SIMULTANEOUS COOKING OF DIFFERENT FOODS
The MULTI-FUNCTION oven set on position
consents a simultaneous
heterogeneous cooking of different foods. Different foods such as fish, cake and
meat can be cooked together without mixing the smells and flavors together. This
is possible since the fats and vapors are oxidized while passing through the
electrical element and therefore are not deposited onto the foods.
The only precaution to follow are:
– The cooking temperatures of the different foods must be as close to as possible,
with a maximum difference of 20° - 25 °C.
– The introduction of the different dishes in the oven must be done at different
times in relation to the cooking times of each one.
The time and energy saved with this type of cooking is obvious.
14
GRILLING AND “AU GRATIN”
Grilling may be done without the roasting jack on position
of the switch,
because the hot air completely envelops the food that is to be cooked.
Set the thermostat to position 175 °C and after having preheated the oven, simply
place the food on the rack.
Close the door and let the oven operate with the thermostat on position 175 °C,
until grilling is done.
Adding a few dabs of butter before the end of the cooking time gives the golden
“au gratin” effect.
Do not grill for longer than 30 minutes at any one time on full heat (175°C).
Caution: the oven door becomes very hot during operation.
Keep children well out of reach.
ROASTING
To obtain classical roasting, it is necessary to remember:
– that it is advisable to maintain a temperature between 180° and 200 °C.
– that the cooking time depends on the quantity and the type of foods.
USE OF THE GRILL
Preheat the oven for about 5 minutes.
Introduce the food to be cooked, positioning the rack as close to the grill as
possible.
The dripping pan should be placed under the rack to catch the cooking juices
and fats.
Grilling with the oven door closed.
Do not grill for longer than 30 minutes at any one time on full heat (200°C).
Caution: the oven door becomes very hot during operation.
Keep children well out of reach.

Injectors replacement of top burners
Every cooker is provided with a set of injectors for the various types of gas.
Injectors not supplied can be obtained from the After-Sales Service.
Select the injectors to be replaced according to the table at page 29.
The nozzle diameters, expressed in hundredths of a millimetre, are marked on the body
of each injector.
To replace the injectors proceed as follows:
– Remove the grids and extract the burner bodies.
– Using a wrench, substitute the nozzle injectors “J” (Fig. 28) with those most suitable for
the kind of gas for which it is to be used (see “Table for the choice of the injectors”).
The burners are conceived in such a way so as not to require the regulation of the
primary air.
Adjusting of the minimum of the top burners
Considering that in the minimum position the flame must have a length of about 4 mm and
must remain lit even with a quick turn from the maximum position to that of minimum.
The flame adjustment is done in the following way:
– Turn on the burner
– Tum the tap to the MINIMUM position
– Take off the knob
– With a small flat screwdriver turn the screw inside the tap rod to the correct regulation (fig.
29).
Normally for LPG, tighten up the regulation screw.
