Instructions for use
Igniting the burners
Hold the flame near the burner and press in and turn the corresponding knob in an
anticlockwise direction. If the burners have not been used for a few days, wait a few
seconds for the air to escape before the gas ignites.
Some models are fitted with automatic ignition, in which case, matches or lighters are
not necessary. For automatic ignition, just turn the knob and press the ignition button
(Fig. 4). For applianced equipped with electronic ignition, simply press down and turn
the control knob to the position marked with a star ★.
After the burner ignites, turn the knob to the control setting required.
Some models are fitted with valves which automatically cut off the supply of gas to
the burner if the flame is accidentally extinguished. The following instructions apply to
the ignition of these burners, whether they are on the hob, in the oven or in the grill:
— turn the knob to Max
— activate the ignition of the gas
— hold the knob in that position for 5 or 6 seconds.
The time lapse allows the safety device to function, and the flame will remain ignited.
NB: After cleaning the hob, make sure that the flame spreader and burner are
correctly positioned. It is most important that the flame spreaders are positioned
in the special slots so as to avoid damage to the burners.
The power absorbed and other technical data can be found on the rating plate
located on the side of the oven door (accessible by opening the door).
Electric oven
Turn the oven knob to the right (Fig. 1 - Fig. 2). Position 1: oven light, allows the
light to be switched on or off as required. As the oven is fitted with a thermostat, the
selected temperature will be maintained automatically by turning the knob to the
required temperature right up to the maximum on position 2. The light stays on while the oven is working.

Caution: Accessible parts may become hot when the grill is in use. Children should be
kept away.
Gas oven
Press in the oven knob, turning it to the left to the maximum flame position (Fig. 6) for
ovens with a heat symbol, and to the maximum position for thermostat ovens (Fig. 5).
Open the oven and hold a lighted taper near the hole at the centre front of the oven,
keeping pressure on the knob for a few seconds until the safety device comes in.
Before closing the door, look through the ferrules at the side of the hole to check that
the burner has ignited. To select the required temperature in an oven fitted with a
thermostat, simply turn the knob to that temperature; a lowering of the flame means
that the selected temperature has been reached. On ovens with a thermometer,
leave the knob on maximum until the required temperature is reached on the thermometer on the oven door. Experience will help you to position the knob so that the required temperature can be maintained.
Electric hotplates
Each hotplate is controlled by a knob with different positions giving different levels of
heat input. When a hotplate is energised an indicator light comes on (fig. 4).

The rotisserie
Some models are fitted with a rotisserie. For correct use follow the instructions below:
— Insert bracket A in the slots in the roof of the oven (Fig. 9).
— Or where supplied insert the support A1 into the holes at the bottom of the oven.
— Fit the meat on the skewer and grip it by pushing the two forks into the opposite
ends of the joint. Fit the pointed end of the skewer into the hole at the back of the
oven and rest the other end on bracket A or A1.
Other models can be fitted with a rotisserie. If required, ask your dealer for the conversion kit.
Useful advice
Advice on the use of the gas burners
— To switch the rotisserie motor on, press the button marked with the symbol shown in Fig. 4
— On some models with an electric oven, the rotisserie comes on automatically with the grill when
the knob is turned to the corresponding symbol.
N.B.: Unscrew the handle from the skewer so
that the grip stays cool.
Use only cookware that has a flat bottom.
Placing small pans on large burners does not aid cooking, it only wastes gas.
For small diameter frying pans and pots (coffee pots, tea pots, etc.) a grill reducer (included with some models) should be used, and the burner must be adjusted so that the
flame only hits the bottom of the pan and does escape up the sides.
Reducers can only be used only on the auxiliary burner.
For the best performance, the following minimum pan diameters are recommended for
the various burners:
• Small
12 cm.
• Medium
16 cm.
• Large
22 cm.
• Auxiliary
6 cm.
Indicator light
In all the cookers which feature one or more electric
plate an indicator light will show the plates are
switched on (Fig. 4).
Fig. 9
Conventional cooking in an electric oven
To set the cooking time, turn the knob right round and then turn it back until the dot
is in line with the required time. When the time is up, an alarm will sound for a few
seconds (Fig. 3).
When using the static oven for traditional style cooking both the top and bottom oven
elements are switched on, it is therefore recommended to place the shelf in the central
guides of the oven.
Timer complete cooking
Cooking with the grill
This mechanism makes it possible to programme the whole cooking period so that the
oven automatically switches off the end of set time (max. 2 hours). Switch on the
oven and set at the required temperature. Turn the dial clockwise and position the
required time, expressed in minutes. When the set cooking time has elapsed the dial
will return to the « O » position and the signal will ring automatically.
When the oven is to be used manually, the control knob has to be set to the
position. (Fig. 3a)
Warming drawer
Below the oven there is a sliding warming drawer, for warming serving dishes by
making use of the residual heat from the oven.
NB: Some models do not have a warming drawer.
WARNING: This drawer should not be used for storing cleaning cloths or
flammable materials, but it may be used for storing kitchen utensils.
Oven accessories
The roasting tray is used directly for cooking food (roasting joints, pastries, pizzas
Oven light
This illuminates the oven interior. On models with gas ovens it is switched on by
pressing the appropriate button (Fig. 4). On models with an electric oven and electric grill it comes on when the thermostat knob is turned (Fig. 1 - Fig. 2). On the latter models the light stays on while the oven and grill are working.
Caution: Accessible parts may become hot when the grill
is in use. Children should be kept away.
This type of cooking browns the food quickly.
For this reason we recommend that the shelf is placed
on shelf level number 4, according to the quantity of the
food (Fig. 9A) being cooked.
Almost all types or meat can be cooked under the grill, with
the exception of some lean game meat and meat loaves.
Meat and fish cooked under the grill should be lightly basted with oil.
Fig. 9A
Cleaning and maintenance
Clean stainless steel and enamelled surfaces with warm water and soap, or with suitable
branded cleaning products. Never use abrasive powders which would damage the surfaces.
The flame spreanders on the burners available in either brass or enamelled steel, should
be washed periodically with hot water and detergent. All encrusted stains should be removed, as they may cause an irregular flame.
Cleaning the oven is very important and should be done after each use. During cooking,
grease is deposited on the walls which, when the oven is next used, can produce unpleasant smells and can also have an effect on the cooking process. Clean it with hot
water and detergent and rinse thoroughly.
To avoid this tedious process, some models can
be fitted with special self-cleaning liners. These
liners are covered with microporous enamel and
are offered as an optional extra. See the section
Use detergents and steel pads for both stainless steel
and enamelled grids. The finish used on stainless
steel grids on the part which comes into contact with
the flame does not reduce its effectiveness.
The toughened glass surfaces (top, oven door, heating compartment door) should be cleaned when
cold. Any breakages caused by ignoring this advice
are not covered by the guarantee.
The inner glass in the oven door can be removed
for cleaning. Using a screwdriver remove screws A, Fig. 10
remove the fixing plates B, and lift out the glass panel
(Fig. 10). Do not use excessive force when replacing screw A.
To keep the electric hotplates shiny, clean them after use with a damp cloth, and
as soon as they have cooled rub in a few drops of mineral oil.
It is good practice to chek periodically the condition of the rubber pipe which connects
the oven to the gas cylinder or to the supply pipe. If there is any evidence of cracking
or splitting, have it replaced with one which complies with the relevant national standard.
To change the bulb inside the oven, disconnect the appliance from the mains supply,
unscrew the glass cover and replace the bulb with a similar heat resistant one.
Catalytic self-cleaning oven
Special self-cleaning liners covered with microporous enamel are offered as an optional
extra on some models, which means that it is unlikely that you will ever need to
manualy clean the oven.
The grease which is deposited on the panels during cooking is removed through a catalytic oxidation process, transforming it into gaseous products. The pores of the enamel
must be kept clear to ensure efficient self-cleaning.
Excessive deposits of grease can block the pores and thereby impede self-cleaning. This
can be remedied by turning the temperature control knob to maximum and leaving the
empty oven on for 10-20 minutes.
Do not use on the oven interior abrasive products, metallic pads, pointed objects, rough
cloths, chemical products or detergent which could cause irreparable damage to the
The use of deep containers is recommended for cooking particularly greasy foods (roasts
etc) as in the use of the roasting tray when cooking under the grill.
This simple operation creates the ideal temperature and conditions for effective catalytic
If, for whatever reason, the self cleaning process is not satisfactory, remove the grease
with a soft cloth or sponge soaked in hot water.
The enamel must remain porous for effective self-cleaning.
NB: All self-cleaning liners on the market have an effective life of about 300 operating
hours, after which they should be replaced.
Technical Assistance
Before calling the Service Agent
If the oven does not work, we advise you to:
— check that the plug is properly connected to the socket, or that the Electrical supply
is correctly made to the appliance. Fuses and switches etc should be checked for
correct operation;
— in the case of a gas oven check that the gas flow is regular and that rubber pipe is
not kinked or blocked.
If your oven still does not work, switch it off, do not tamper with it and call the Service
Before calling out the Service Agent make a note of the serial number which is
printed on the product identification plate (p. 4).
General Notice
When using the grill, the door should always remain open. When the grill or the
oven are being used, the cooker becomes very hot as does the glass in the door
and the surrounding parts. So, make sure that children do not touch the appliance.
When using the grill or the oven, the glass top (for those models where one is
fitted), should always be left open. Also, do not close the top while the burners
are still hot.
The use of both gas grill and gas oven simultaneously is not allowed.
Installation is the responsibility of the purchaser, and any work carried out by the
manufacturer due to incorrect installation is not covered by the warranty.
It is essential that everything concerning installation and adjustment is carried ou by
a qualified person, in accordance with the current regulations.
An additional protective means to avoid contact with the oven door is available.
This part should be fitted when young children are likely to be present.
This protective means, code 9194675.6 (cookers with width 540 or 900) and code
9194674.9 (cookers with width 650), can be obtained calling our service department.
Instruction for the installer
The installation of the appliance should only be carried out by a qualified person. Any work on the appliance should be done while it is disconnected from
the power supply.
For normal operation the installer should follow the
relevant national standard. The appliance is thermally insulated (in line with regulation EN) and may
be installed: next to panels higher than the worktop,
for type “Y”, or next to panels not higher than the
worktop for type “X”.
The 900 mm. cookers are Class. 1
The 540 mm. and 650 mm. cookers are Class 2,
Fig. 11
below Class 1 (according to the EN 30 norm).
The minimum vertical distance from the work plain
to any cabinets above must be at least 70 cm. For installing an exhaust hood, see the
installation instructions for the hood itself.
In the instruction envelope there are two feet with clamps, which when positioned in
the slots provided (on the base of the cooker), allows precise alignment with other kitchen
furniture (Fig. 11).
Gas connection
Connect the cooker to the gas bottle or the gas pipe in accordance with the provisions
of the relevant national standard only after makind sure the cooker has been adjusted
for the type of gas it will be supplied with. Otherwise perform the adjustment operations
described in the paragraph «adaptation to the different type of gas».
When the appliance is supplied by liquid gas use pressure regulators which complies
with the relevant national standard.
Rubber hose connection
To make the connection, use a gas hose corresponding with the characteristics specified by the national standards.
Make sure the hose is snugly fit a both ends and use
a standard hase clamp to fasten it.
The hose must not be subject to any tractiv or torsional
stress and it must not have any excessively narrow
curves or bottlenecks.
WARNING: Rubber pipe connection is not allowed in
case of appliance fitted permantly.
A suitable location
For a gas appliance to work well it is essential that it
is located where the air can flow naturally, enabling
efficient operation.
The flow of air in this area should come directly from
openings made in the outside kitchen wall (see Fig. 12).
These openings should have an unobstructed area of
a least 100 cm2 (one or two openings can be made).
• Gas methane or city gas connection
The internal diameter of the hose must be 13 mm to
fit connection A (Fig. 14).
Fig. 12
Discharging the products of combustion
Gas cookers must be connected to flues or directly to
the outside (Fig. 13).
If a vent cannot be installed, an electric fan must be
fitted to an outside wall or outside window, as long as
there are openings to let air into the area.
This electric fan must be able to ensure, in a kitchen
environment, an hourly change of air 3-5 times its volume.
Fig. 13
Attached to the cooker there is a plate which shows which type of gas it is set for.
If you intend to use the same type of gas for which the cooker has been set up, follow
carefully the instructions for connection.
If you intend to use another type of gas, read the instructions on page 14 concerning
adapting the cooker for different types of gas before reading the instructions for connection.
• Bottle gas connection
Make the connection to the gas bottle with a hose of
internal diameter 8 mm to fit the connection B (Fig. 14).
Note: The gas bottle must be kept in its specific compartment or base cabinet away from heat sources.
With regards to cookers equipped with bottle gas compartment, the rubber hose connection, must be
made as shown in Fig. 15 ensuring the hose is kept
as far as possible from the oven.
IMPORTANT: The hose must be easy to inspect along
its entire leght to check its wear.
Metal hose connection
When carring out this type of connection ensure that
the appliance is not subject to any kind of stress. The
cooker inlet pipe is fitted with an end connection which
be turned to the required position.

Electrical connection
Cookers intended for connection to the electrical power supply are designed to work on
alternating single phase current. The total power absorbed and further technical data can
be found on the plate attached on the side of the oven door (accessed by opening the
oven door).
The appliance complies with the safety requirements laid down by the standards institutes.
Some models come with a bipolar plug with earth connection which ensures that the
appliance is fully earthed.
The safety of the appliance is, however, dependent on the correct earthing of your power
supply. So, before connecting your appliance to the mains supply make sure that:
1) that the socket is correctly earthed
2) that the electricity meter’s amp. capacity is suitable for the consumption indicated on
the cooker’s rating plate.
WARNING: Appliances not fitted with a plug, require a fixed installation with a bipolar switch, which has a gap between the contacts of at least 3 mm.
The earth cable must be controllable by the switch.
The manufacturer cannot accept any responsibility when safety regulations have
been ignored.
Adapting the appliance for different types of gas
To adapt the cooker for types of gas other than for which it has been set carry out the
following operations in order.
Changing the injectors
Replacement injectors are supplied in special bags. Each injector is stamped with its diameter in hundredths of a millimetre. The correct injector should be selected in accordance with the instructions in the «Gas Consumption» table.
• The hob
Remove the pan supports, flame spreaders and burners and carry out the replacement through the burner
support bracket (Fig. 16) using the special spanner
• Gas oven
Open the door and remove the oven base. Remove the
warming drawer and unscrew the fixing screws «A» located on the upper side of the crosspiece (Fig. 17A).
Slide out the burner and replace the injector (Fig. 17B).
NB: If the oven is fitted with self-cleaning liners, they
should be removed, so that the oven base can be
WARNING: When carrying out the above operation,
check that the injectors are properly and firmly secured.
Adjusting the appearance of the flame
The flame is fed by a mixture of gas and air. The air
supply has to be adjusted so that the correct mixture
reaches the burners.
To make the adjustment, carry out the following:
• Remove the grill and take out the burner.
• Ensure the small air regulating tubes are fitted as
shown in table K. A good flame should be welle defined
and without yellow points (Fig. 18 position B).
If there is insufficient air, the flame will be loing and soft
(Fig. 18 position A). If this is the case, the air regulator
pipe must be moved further up the venturi tube. If there
is too much air however, the flame is short and hisses
(Fig. 18 position C) and tends to be detached from the
burner. In this case, the regulator pipe (Fig. 18 W)
should be withdrawn from the venturi tube.
The pressures are as follows:
30 mbar liquid gas; 20 mbar for methane gas, the
air regulator pipes should be positioned on the burners
as shown in table «K».
At operation completed ensure that the screw H is firmly
• Oven. Open the door, remove the floor and slacken
the retainer (Fig. 19). Slide the regulator R by adjusting
the retainer F until a flame with the correct carburation
is obtained. To reduce the amount of air, move R in the
direction of the arrow.
Adjusting the minimum position
• The control taps (hob and oven with thermostat)
Ignite the burners and turn the control tap to minimum
position. Pull off the knob (it is just a push fit) and using
a small screwdriver turn the adjuster screws A (Fig. 20)
anti-clockwise to increase the flow of gas or clockwise
to reduce the flow, until the flame is 3/4 mm long.
• Gas oven thermostat (Fig. 21)
Having kept the oven working at maximum with the door
closed for about 10 minutes, turn the thermostat knob
to 150° C. Remove the knob and:
— if changing from methane to LPG screw in the thermostat by-pass screw (Fig. 21);
— if changing from LPG gas to methane unscrew the
by-pass screw 1/4 of a turn until you get a small, regular flame.
Then, by turning the knob rapidly from maximum to
150° C, and by rapidly opening and closing the oven
door, check to see that the burner does not go out.
