• Standard EN30-2-1 (hobs: gas red burners).
USE OF THE APPLIANCE, ENERGY SAVING TIPS
OVEN
• Check the oven door always closes properly and the door gasket is clean and in order.
During use, open the oven door only when strictly necessary to avoid heat losses (for
some functions it may be necessary to use the oven with the door half-closed, check
the oven operating instructions).
• Turn off the oven 5-10 minutes before the end of the theoretical cooking time to
recuperate the stored heat.
• We recommend using oven proof dishes and adjusting the oven temperature during
cooking if necessary.
HOB
GAS FIRED BURNERS
• It is important that the diameter of the pot be suitable to the size of the burner so as
not to compromise the high output of the burners and therefore energy waste. A small
pot on a large burner does not give you a boiling point in a shorter amount of time
since the capacity of heat absorption of a liquid mass depends on the volume and the
surface of the pot.
• Avoid keeping a burner on without something on it (without pot).

Notes:
• The electric ignition is incorporated in the knobs.
• The appliance has a safety valve system tted, the ow of gas will be stopped if and
when the ame should accidentally go out.
CAUTION:
If the burner is accidentally extinguished, turn the gas off at the control knob and wait at
least 1 minute before attempting to relight.
CAUTION:
Gas hobs produce heat and humidity in the environment in which they are installed.
Ensure that the cooking area is well ventilated by opening the natural ventilation grilles or
by installing an extractor hood connected to an outlet duct that vents to the outside.
CAUTION:
If the hob is used for a prolonged time it may be necessary to provide further ventilation
by opening a window or by increasing the suction power of the extractor hood if tted and
vented to the outside.

Please note: This appliance incorporates a safety cooling fan which you will hear operating
whenever the oven or grill is being used.
The cooling fan may even run on after the appliance has been switched off.
The duration of this time is dependent on several factors, including previous cooking
temperature, duration and ambient temperature. Times in excess of 30 minutes are not
uncommon.

11
3 - USE OF THE HOB BURNERS
Caution!
The cooking hob becomes very hot
during operation.
Keep children well out of reach.
N.B. When the cooker is not being
used, set the gas knobs to their closed
positions.
GAS BURNERS
Gas ow to the burners is adjusted by
turning the knobs (illustrated in g. 3.1)
which control the safety valves.
Turning the knob, so that the indicator line
points to the symbols printed on the panel,
achieves the following functions:
- symbol closed valve
- symbol maximum
aperture or ow
- symbol minimum
aperture or ow
√The maximum aperture position
permitsrapidboilingofliquids,whereas
the minimum aperture position allows
slower warming of food or maintaining
boiling conditions of liquids.
√ To reduce the gas ow to minimum
rotate the knob further anti-clockwise
to point the indicator towards the small
ame symbol.
√Other intermediate operating
adjustments can be achieved by
positioning the indicator between the
maximum and minimum aperture
positions, and never between the
maximum aperture and closed
positions.
Fig. 3.1
Fig. 3.2
Caution!
Do not cover the hob with aluminium
foils.
NOTE:
The knob and symbols may vary.

12
DEEP FAT FRYING
For safety purposes when deep fat frying,
do not ll the pan more than 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 re, leave
the pan where it is and turn off the control
knobs.
Place a damp cloth or lid over the pan to
smother the ames. Leave the pan to cool
for at least 30minutes before moving the
pan.
DO NOT USE WATER ON THE FIRE.
LIGHTING THE BURNERS
To ignite the burner, the following
instructions are to be followed:
1. Press in the corresponding knob and
turn counter-clockwise (g. 3.2) to the
full ame position marked by the
symbol (g. 3.1); hold the knob in until
the ame has been lit.
In the case of a mains failure light the
burner with a match or lighted taper.
2. Wait for a few seconds after the gas
burner has been lit before letting go of
the knob (valve activation delay).
3. Adjust the gas valve to the desired
position.
If the burner ame should go out for some
reason, the safety valve will automatically
stop the gas ow.
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 difcult
to light the burner with the knob set to
maximum, set the knob to minimum and
repeat the operation.
CHOICE OF THE BURNER
On the control panel, near every knob
there is a diagram that indicates which
burner is controlled by that knob.
The suitable burner must be chosen
according to the diameter and the capacity
used.
The burners and pans must be used in
accordance with the following instructions:
DIAMETERS OF PANS WHICH MAY
BE USED ON THE BURNERS
BURNERS MINIMUM MAXIMUM
Auxliliary 12 cm 14 cm
Semi-rapid 16 cm 24 cm
Triple-ring 26 cm 28 cm
Wok max 36 cm
do not use pans with concave or
convex bases
Fig. 3.3
It is important that the diameter of the pot
be suitable to the potentiality of the burner
so as not to compromise the high output
of the burners and therefore energy waste.
Asmall pot on a large burner does not give
you a boiling point in a shorter amount of
time since the capacity of heat absorption
of a liquid mass depends on the volume
and the surface of the pot. Too large a
pot can cause damage to the burner and
surrounding hob area.
CAUTION: Make sure the pans are central
to the burner for maximum stability and
greater efciency.
Make sure the pans are not in contact with
the control knobs, otherwise the ame
could overheat the knobs and permanently
damage them.

13
CORRECT USE OF THE TRIPLE-RING BURNER
Only at bottom pans of the correct size are to be placed on the pan support above the
Triple-ring burner.
When using a WOK, the supplied wok stand must be placed onto the pan stand to avoid
any faulty operation of the triple-ring burner (g. 3.4a). The wok should not be placed
directly onto the pan support without the use of the supplied wok stand (g. 3.4b).
IMPORTANT:
When using the wok stand it MUST ONLY BE PLACED over the pan support for the triple-
ring burner (g.3.4a). Under no circumstances should the wok stand be placed under
the pan supports (gs 3.5a - 3.5b). Incorrect placement of the wok stand in this manner
may impinge the ame resulting in incomplete combustion and give rise to harmful levels
of Carbon Monoxide (CO).

OPERATING PRINCIPLES
Heating and cooking in the conventional
oven are obtained:
a. by natural convection
The heat is produced by the upper and
lower heating elements.
b. by radiation
The heat is irradiated by the infra red grill
element.
Before introducing the food, preheat the
oven to the desired temperature.
For a correct preheating operation, it is
advisable to remove the tray from the oven
and introduce it together with the food,
when the oven has reached the desired
temperature.
Check the cooking time and turn off the
oven 5 minutes before the theoretical time
to recuperate the stored heat.
GENERAL FEATURES
2differentthermostatic controlfunctions are
availabletosatisfyallcookingrequirements,
provided by 3 heating elements:
• Top element
• Bottom element
• Grill element
NOTE: Upon rst 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 , mode
in order to eliminate any traces of grease
from the electrical elements.
Clean the oven and accessories with warm
water and washing-up liquid.
Smells and fumes produced during this
burn off process are not a cause of alarm.
Adequate ventilation should however be
provided in the room where the appliance
is installed, e.g. by opening a window.
Attention: The oven door becomes
very hot during operation.
Keep children away.
ATTENTION - MOST IMPORTANT
Pay special attention not to touch the
hot heating element inside the oven
cavity.
WARNING:
The door is hot, use the handle.
During use the appliance becomes hot. Care should be taken to avoid touching
heating elements inside the oven.
Do not line the oven walls or base with aluminium foil. Do not place baking trays
or the drip tray on the base of the oven chamber.

By setting the knob to this position, only the oven light comes on.
The light remains on whilst any of the cooking modes are selected.

16
TRADITIONAL CONVECTION COOKING
The upper and lower heating elements are switched on.
The heat is diffused by natural convection and the temperature must be set between 50°C
and 250° C.
It is necessary to preheat the oven before adding the foods to be cooked.
Recommended for:
For foods which require the same cooking temperature both internally and externally, i. e.
roasts, spare ribs, meringue, etc.
ECO FUNCTION (ENERGY SAVING)
The upper and lower heating elements are switched on.
The heat is diffused by natural convection.
This function reduces the appliance’s energy consumption, it is therefore particularly
benecial for the gentle cooking of small quantities of food on a single shelf.
It is not necessary to preheat the oven and use with the oven door closed.
Cooking times may be longer than standard functions.
Do not use this function to preheat the oven.
Recommended for:
Foods that require gentle cooking. To keep foods hot after cooking. To slowly heat already
cooked foods.
GRILLING
The infra-red heating element is switched on.
The heat is diffused by radiation.
Use with the oven door closed and the temperature knob to 200°C maximum.
Leave to warm up for approximately 5 minutes with the door closed.
Place the food inside positioning the rack as near as possible to the grill.
Insert the drip pan under the rack to collect the cooking juices.
Recommended for:
Intense grilling, browning, cooking au gratin and toasting etc.
Grill with the oven door closed.
Do not grill for longer than 30 minutes at any one time (Grilling for longer than
the reccomended time may mean the appliance overheats).
Caution: The oven door becomes very hot during operation. Keep children well
out of reach.

The oven temperature can be
set between 50°C - 250°C.
The set temperature has been
reachedwhenthetemperature
indicator light goes out.
Several different meals may
be cooked simultaneously
on various shelves, as the
heated air circulates evenly
throughout the oven.
Thehot airsystemcooks more
quickly than conventional
static system, therefore the
temperature should be set
10°C - 20°C below the values
recommended in your recipe
books.
The oven door may be opened
briey while cooking to check
on the food, as any heat
losses are quickly recovered
when the door is closed.
WARNING:
The door is hot, use the handle.
During use the appliance becomes hot.
Care should be taken to avoid touching
heating elements inside the oven.
Fig. 5.1
COOKING WITH FORCED AIR
Preheat the oven at the desired
temperature, the set value is reached
when the temperature indicator light
goes off.
For a correct preheating it is advisable
to remove the shelves from the oven
and reintroduce then, with the food,
when the oven has reached the desired
temperature.
Fan cooking is more economical and
quicker than cooking in a conventional
oven.
The moving hot air surrounds the food
and penetrates it more quickly than in a
conventional oven.
Cooking yeast based dishes is also
speeded up this way. If the oven door has
been opened, the oven quickly regains its
temperature once the door is closed.
