4 How to use the hob burners

Hob burners

Each hob burner is controlled by a
separate gas tap operated by a control
knob (fig. 4.1) which has 3 positions
marked on the knob itself, 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.

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 symbol
to the indicator 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.

Low 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.

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.

Burners Pan diameter

Auxiliary 12 ÷ 14 cm
Semi-rapid 16 ÷ 24 cm
Rapid 24 ÷ 24 cm
Triple-ring 26 ÷ 28 cm

do not use pans with concave or convex bases

Fig. 4.2

Choice of burner

The burner must be choosen according to the diameter of the pans and energy required.

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.

Correct use of the triple-ring burner

The flat-bottomed pans are to be placed directly onto the pan-support.
To use the WOK you need to place the proper stand in order to avoid any faulty

operation of the triple-ring burner (Fig. 4.4a - 4.4b).

IMPORTANT:

The special grille for wok pans (fig. 4.4b) MUST BE PLACED ONLY over the pan-rest for the
triple-ring burner.

5 How to use the Multifunction oven

General features

Attention: the oven door becomes
very hot during operation.
Keep children away.

As its name indicates, this is an oven that
presents particular features from an opera­tional point of view.

In fact, it is possible to insert 7 different
programs to satisfy every cooking need.
The 7 positions, thermostatically con­trolled, are obtained by 4 heating ele­ments which are:

– Bottom element 1725 W
– Top element 1725 W
– Grill element 2500 W
– Circular element 2500 W
– Fan motor 25 W
– Oven lamp 15 W

NOTE:

Upon first use, it is advisable to operate the
oven for 30 minutes in the position and
for another 30 minutes at the maximum tem­perature (thermostat knob on position 225) in
the positions

and

, to eliminate possi­ble traces of grease on the heating elements.
Clean the oven and accessories with warm
water and washing-up liquid.

WARNING:
The door is hot, use the handle.

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 irradiated 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.

f. by ventilation

The food is defrosted by using the fan
only function without heat.

FUNCTION SELECTOR KNOB (Fig. 5.1)

Rotate the knob clockwise to set the oven
for one of the following functions.

THERMOSTAT KNOB (Fig. 5.2)

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).

Fig. 5.1

Fig. 5.2

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.
