How to Use the Hob Burners

Hob Burners

Each hob burner is controlled by a separate gas valve operated
by a control knob (fig. 11) which has 3 positions marked on the
control panel, these are:

– Symbol

: Tap closed (burner off)

– Symbol

– Symbol

Push in and turn the knob anti-clockwise to the selected
position.
The maximum aperture position permits rapid boiling of liquids,
whereas the minimum aperture position allows slower warming
of food or maintaining boiling conditions of liquids.
To reduce the gas flow to minimum, rotate the knob further anti­clockwise to point the indicator towards the small flame symbol.
Other intermediate operating adjustments can be achieved by
positioning the indicator between the maximum and minimum
aperture positions, not between the maximum aperture and
closed positions.

Note: When the hob is not being used, set the gas knobs to their closed positions and also
close the cock valve on the gas bottle or the main gas supply line.

: High (maximum)

: Low (minimum)

Fig. 11

Lighting of the Hob Burners

To ignite the burner, the following instructions are to be followed:
1 - Press in the corresponding knob and turn counter-clockwise to the full flame position marked by the

symbol (fig. 11) and hold the knob in until the flame has been lit.

In the case of a mains failure light the burner with a match or lighted taper.
2 - Wait about ten seconds after the gas lighting before releasing the knob (starting time for the valve).
3 - Adjust the gas valve to the desired power.

Important

If the burner flame should go out for some reason, the safety valve will automatically stop the gas flow.
To re-light the burner, return the knob to the closed position, wait for at least 1 minute and then
repeat the lighting procedure.
If your local gas supply makes it difficult to light the burner with the knob set to maximum, set the knob
to minimum and repeat the operation.

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.

Do not use pans with concave or convex bases

Correct Use of 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 triple­ring burner (Figs. 13 - 14).
Important: The wok pan stand (fig. 14) MUST BE PLACED ONLY over the pan-rest for the triple-ring
burner.

How to Use the Multifunction Main Oven

General Features

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 programmes to satisfy every
cooking need.
The 7 positions, thermostatically controlled, are obtained by 4 heating
elements which are:
– Bottom element 1200 W
– Top element 1000 W
– Grill element 2000 W
– Circular element 2200 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 250) 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.

ATTENTION - MOST IMPORTANT
Pay special attention not to touch the hot heating element
inside the oven cavity.

Attention:

The oven door
becomes very hot
during operation.

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.

f. by ventilation

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

12

Thermostat Knob (fig. 15)

This only sets the cooking temperature and does not switch the oven on.
Rotate clockwise until the required temperature is reached (from 50 to 250°C).
The light between the thermostat and the function selector will illuminate when the oven is switched 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.

Fig. 15 Fig. 16

Function Selector knob (fig. 16)

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

Oven Light

By setting the knob to this position, only the oven light comes on.
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 250°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.

13

Grilling

The infrared grill element comes on. The heat is dispersed by radiation.

Use with the oven door closed and the thermostat knob to position 225°C for max 15 minutes, then
to position 175°C.
For cooking hints, see the chapter “USE OF THE GRILL”.

Recommended for:

Intense grilling, browning, cooking au gratin and toasting etc.

It is recommended that you do not grill for longer than 30 minutes at any one time.
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.

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.

14

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 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.

It is recommended that you do not grill for longer than 30 minutes at any one time.
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 150°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 250°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.
