HOB BURNERS
Each hob burner is controlled by a sep-
arate gas tap operated by a control
knob (fig. 4.1) which has 3 positions
marked on the control panel, these are:
– Symbol 0: tap closed (burner off)
– Symbol : High (maximum)
– Symbol : Low (minimum)
Push in and turn the knob anti-
clockwise to the selected position.
Low High
To turn the burner off, fully rotate the knob clockwise to the off position: 0.
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.
Fig. 4.1
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.

CHOICE OF THE BURNER
On the control panel, near each knob, there is a diagram that indicates which burner
is controlled by that knob.
Select the burner that is most suitable for the diameter and capacity of the pan to be
used.
As an indication, the burners and the pans must be used in the following way:
It is important that the base diameter of the pot is at least the same diameter as the
burner ring to obtain an efficient heat transfer.
Always position pans centrally over the burners.
Adjust the size of the flame so that it does not lick up the side of the pan.
Position pan handles so that they cannot be accidentally knocked.
Fig. 4.2
BURNERS POT DIAMETER
Auxiliary 12 - 14 cm
Semi-rapid 16 - 24 cm
Rapid 24 - 26 cm
Triple-ring 26 - 28 cm
do not use pans with concave or convex bases
LIGHTING THE 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. 4.1).
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.

GENERAL FEATURES
The heating and cooking in electrical
hot air ovens take place by forced con-
vection.
The two elements which make this
process take place are:
- Circular element 2500 W
- Grill element 2000 W
NOTE:
Upon first use, it is advisable to operate
the oven at the maximum temperature
(thermostat knob on position 250) for
60 minutes in the position (fan
oven) and for another 15 minutes in the
position (thermostat knob on posi-
tion 200°C), to eliminate possible traces
of grease on the heating elements.
WARNING:
The door is hot, use the handle.
ATTENTION - MOST IMPORTANT
Pay special attention not to touch
the hot heating element inside the
oven cavity.
OPERATING PRINCIPLES
Heating and cooking in the FAN oven
are obtained in the following ways:
a. 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.
b. by radiation
The heat is radiated by the infra red
grill element.
c. by ventilation
The food is defrosted by using the fan
only function without heat.

FUNCTION SELECTOR KNOB (Fig. 5.2)
Rotate the knob clockwise to set the oven for one of the following functions.
THERMOSTAT KNOB (Fig. 5.1)
This only sets the cooking temperature and does not switch the oven on. Rotate clock-
wise until the required temperature is reached (from 50 to 250°C).
The light above the temperature selector will illuminate when the oven is swiched on
and turns off when the oven reaches the correct temperature.
The light will cycle on and off during cooking in line with the oven temperature.
OVEN LIGHT
By setting the knob to this position, only the oven light comes on.
It remains on in all the cooking modes.
DEFROSTING FROZEN FOODS
Only the oven fan comes on. Use with the thermostat knob set to “0” - 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.

14
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.
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 250°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.
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.

15
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.
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.
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 FAN 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 pass-
ing 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.

16
THERMOSTAT KNOB (Fig. 6.2)
This only sets the cooking temperature
and does not switch the oven on.
Rotate clockwise until the required tem-
perature is reached (from 50 to 250°C).
The light above the temperature selector
will illuminate when the oven is swiched
on and turns off when the oven reaches
the correct temperature.
The light will cycle on and off during
cooking in line with the oven tempera-
ture.
GENERAL FEATURES
The conventional oven is provided with 3
heating elements which are:
– Bottom element 800 W
– Top element 700 W
– Grill element 1450 W
NOTE:
Upon first use, it is advisable to operate
the oven at the maximum temperature
(thermostat knob on position 250) for
60 minutes in the position and for
another 15 minutes in the position
(thermostat knob on position 200°C),
to eliminate possible traces of grease on
the heating elements.
WARNING:
The door is hot, use the handle.
ATTENTION - MOST IMPORTANT
Pay special attention not to touch
the hot heating element inside the
oven cavity.
