GAS BURNERS
Gas flow to the burners is adjusted by
turning the knob (illustrated in fig. 2.1)
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:
✓ full circle
● = closed valve
✓ symbol = maximum
aperture or flow
✓ symbol = minimum
aperture or flow
To light one of the gas burners, hold a
flame (e.g. a match) close to the top part
of the burner, push in and turn the
relative knob in an anti-clockwise
direction, pointing the knob indicator
towards the large flame symbol (i.e.
max. gas flow).
To reduce the gas flow to minimum,
rotate the knob further anti-clockwise to
point the indicator towards the small
flame symbol.
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.
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.
N.B. When the cooker top 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.
Fig. 2.2
The device shall not be operated for
more than 15 seconds. If after 15
seconds the burner has not lit, stop
operating the device and open the
compartment door and/or wait at
least 1 minute before attempting a
further ignition of the burner.

VALVELESS ELECTRIC SPARKLIGHTING GAS BURNERS
To light one of the gas burners, push in
and turn the relative knob to the maximum aperture position (large flame symbol) and hold the knob in until the flame
has been lit.
The sparks produced by the lighter situated inside the relative burner will light
the flame.
In the event that the local gas supply
conditions makes it difficult to light the
burner in maximum aperture position, try
again with the knob in minimum position.
LIGHTING GAS BURNERS
FITTED WITH SAFETY VALVE
DEVICE
In order to light the burner, you must:
1 – Turn the knob fig. 2.2 in anti-clock-
wise direction up to the maximum
aperture, push in and hold the
knob; this will light the gas. If there
is no mains electrical supply, bring
a lighted match close to the burner.
2 – Wait about ten seconds after the
gaslights before releasing the knob
(starting time for the valve).
3 – Adjust the gas valve to the desired
position.
If the burner flame should go out for
some reason, the safety valve will automatically stop the gas flow.
To re-light the burner, first turn the oven
control knob to position ●, wait for at
least 1 minute and then repeat the
lighting procedure.
CHOICE OF BURNER (fig. 2.3)
The symbols printed on the panel beside
the gas knobs indicate the correspondence between the knob and the burner.
The most suitable burner is to be chosen
according to the diameter and volume
capacity of the container to be warmed.
It is important that the diameter of the
pots or pans suitably match the heating
potential of the burners in order not to
jeopardise the efficiency of the burners,
bringing about a waste of gas fuel.
A small diameter pot or pan placed on a
large burner does not necessarily mean
that boiling conditions are reached quicker.
Caution!
the cooking hob becomes very
hot during operation.
Keep children well out of reach.

NORMAL HOTPLATE
To turn on the electric hotplate, rotate
the knob (fig. 3.1) o the desired setting.
The numbers from 1 to 6 indicate the
operating positions with increasing number corresponding to higher temperature
settings
When the pan comes to the boil, turn the
heat down to the level desired.
Remember that the hotplate will continue
to produce heat for about five minutes
after it has been turned off.
RAPID HOTPLATE (red dot)
The rapid hotplate control knob is similar
to that of the normal hotplate, with 6
selectable heating positions (fig. 3.1).
The characteristics of this hotplate,
which is also equipped with a thermostatic cut-off device, make it possible to:
– achieve the cooking temperature
rapidly
– make full use of its output power using
flat-bottomed pans
– limit the output power with unsuitable
saucepans.
PROPER USE OF THE ELECTRIC HOTPLATE
(fig. 3.2)
When the pan comes to the boil, turn the
heat down to the level desired.
Remember that the hotplate will continue
to produce heat for about five minutes
after it has been turned off.
While using the electric hotplate, you
must:
✓ avoid keeping it on without
something on it;
✓ avoid pouring liquids on it while it is
hot;
✓ use flat-bottomed (electric hotplate
type) pots and pans only
✓ use cooking receptacles which cover
as much of the surface of the
hotplate as possible.
✓ to save electricity, use lids whenever
possible.
✓ never cook food directly on the
hotplate: always use a pan or
suitable container.
An indicator light located on the control
panel signals that the hotplate is operating

The main characteristic of this pyroceram cooker top is that it permits rapid vertical transmission of the heat from the
heating elements below to the
saucepans on top.
The heat does not spread horizontally,
however, and therefore the glass stays
cold only a few centimetres from the hob.
The hobs are controlled by the continuous energy regulation switch (0÷12) (fig.
4.1).
The heat intensity can be regulated continuously from 0 (off) to “12” (max).
Check that the hob is clean and then
switch on by turning the control knob
When the top is working, the pilot light
will be on.
When the hob temperature is above
60°C, the corresponding indicator light
will come on to indicate that the hob is
hot.
This light will stay on even after the hob
has been switched off to indicate that the
hob is still hot.
The residual heat persists for some time
after the hob has been switched off.
During this time avoid touching
the hob and take particular care if
there are children nearby.
The light will go out automatically when
the hob temperature drops below 60°C.

HINTS FOR SAFE USE OF
THE HOBS
– Before switching on, check which
knob controls the required hob. You
are advised to place the saucepan on
the hob before switching on and to
take it off after switching off.
– Use saucepans with an even flat bot-
tom (be careful of cast iron
saucepans). Uneven bottoms can
scratch the pyroceram surface. Check
that the bottom is clean and dry.
– Check that the saucepan handle does
not protrude from the top to avoid
knocking it over. This precaution also
makes it more difficult for children to
reach the saucepan.
– Do not use the top if the surface is
broken or damaged.
– Do not bend over the hobs when they
are on.
– Do not leave aluminium foil, grease-
proof paper etc. or plastic on the hob
when it is hot.
– Remember that the hobs stay hot for
quite a long time (approx. 30 min.)
after they have been switched off.
– Scrupulously follow the cleaning
instructions.
– Do not drop heavy or sharp objects on
the glass ceramic cooktop.
– If you note a crack in the cooktop,
switch the appliance off
immediately and call the After-Sales
Service.
– Never cook the food directly on the
glass ceramic cooktop, but in special
pans or containers.

CHOOSING SUITABLE
SURROUNDINGS
(for gas models)
The room where the gas appliance is to
be installed must have a natural flow of
air so that the gas can burn (in
compliance with the current laws in
force).
The flow of air must come directly from
one or more openings made in the
outside walls with a free area of at least
100 cm
2
.
If the appliance does not have a noflame safety device this opening must
have an area of at least 200 cm
2
.
The openings should be near the floor
and preferably on the side opposite the
exhaust for combustion products and
must be so made that they cannot be
blocked from either the outside or the
outside.
When these openings cannot be made,
the necessary air can come from an
adjacent room which is ventilated as
required, as long as it is not a bedroom
or a danger area (in compliance with the
current laws in force).
In this case, the kitchen door must allow
the passage of the air.
DISCHARGING PRODUCTS
OF COMBUSTION
Extractor hoods connected directly to
the outside must be provided, to allow
the products of combustion in the gas
appliance to be discharged (fig. 6.6).
If this is not possible, an electric fan
may be used, attached to the external
wall or the window; the fan should have
a capacity to circulate air at an hourly
rate of 3-5 times the total volume of the
kitchen (fig. 6.7).
The fan can only be installed if the
room has suitable vents to allow air to
enter, as described under the heading
“Choosing suitable surroundings” (in
compliance with the current laws in
force).

- Make sure the tube is snugly fit
at both ends and use a standard
tube clamp (not supplied) to
fasten it.
- The rubber tube must be as short
as possible, without contractions
or kinks.
- The rubber tube must never be at
any point in its lenght in contact
with the “hot” parts.
- From time to time check to make
sure that the rubber is in perfect
condition and substitute it at
printed due date or if it shows
signs of wearing or damage.

ADAPTING THE APPLIANCE
TO FUNCTION WITH DIFFERENT TYPES OF GAS
If a gas different from that indicated on the
label is used, adapt the cooktop to this new
function.
If the injectors are not supplied they
can be obtained from the “Service
Centre”.
Select the injectors to be replaced
according to the table at page 27).
The nozzle diameters, expressed in
hundredths of a millimetre, are marked
on the body of each injector.
OPERATIONS TO BE PERFORMED WHEN SUBSTITUTING THE INJECTORS
✓ Remove the gratings, the burner
covers and the knobs;
✓ Using a wrench substitute the nozzle
injectors “J” (Fig. 7.3 - 7.4) with
those most suitable for the kind of
gas for which it is to be used.
The burner are conceived in such a
way so as not to require the regulation of the primary air.

REGULATING THE BURNER
MINIMUM SETTING
When switching from one type of gas to
another, the minimum flow rate must
also be correct: the flame should not go
out even when passing suddenly from
maximum to minimum flame.
To regulate the flame follow the instructions below:
– Light the burner
– Set the cock valve to minimum
On gas valves provided with adjustment screw in the centre of the shaft
(fig. 7.5):
– Using a screwdriver with max. diame-
ter 3 mm, turn the screw inside the tap
until the correct setting is obtained.
On gas valves provided with adjustment screw on the valve body
(fig. 7.6):
– Turn the screw “A” to the correct set-
ting with a screwdriver.
For G 30/G 31 gas, tighten the adjustment screw completely.
LUBRICATING THE GAS TAPS
If one of the gas taps becomes difficult to
turn, dismantle it, thoroughly clean with
petrol and apply special high-temperature
grease.
These operations must be performed by
a specialised engineer.

IMPORTANT: Installation has to be
carried out according to the instructions provided by the manufacturer.
Incorrect installation might cause
harm and damage to people, animals or objects, for which the manufacturer accepts no responsibility.
DETAILS
✓ Connection to the electric power sup-
ply must be carried out by a qualified
technician and following the appropriate safety regulations;
✓ Before carrying out the connection to
the power supply, the voltage rating of
the appliance (stamped on the appliance identification plate) must be
checked for correspondence to the
available mains supply voltage, and
the mains electric wiring should be
capable of handling the cooker’s
power rating (also indicated on the
identification plate);
✓ The appliance is supplied without a
power supply plug and therefore if you
are not connecting directly to the
mains, a standardized plug suitable for
the load must be fitted.
✓ The power point must be connected to
a suitable earth wiring, in conformity to
current safety regulations.
✓ The colours of the wires in the hob
power cable may not correspond with
the colours marked on the terminals of
your electrical plug. The plug should in
any case be wired as follows:
– connect the green/yellow wire to the
terminal marked with the letter PE or
the earth symbol or coloured
green/yellow;
✓ It is possible to connect the appliance
directly to the mains supply by means
of a heavy duty switch with 3 mm minimum distance between the contacts.
✓ The power supply cord must not touch
against any hot surfaces and must be
placed so that its temperature does
not exceed 75°C at any point along its
length.
✓ After having installed the appliance,
the power switch or power plug must
always be in a accessible position.
✓ The appliance must have its own
supply; any other appliances installed
near it must be supplied separately.
–
N.B. For connections to the mains
power supply, never use adaptors,
reductions or multiple power points
as these may overheat and catch fire.
In the event that installation should
require modifications to the mains supply
wiring system, it is recommended that a
qualified technician be called to carry out
substitution.
The technician will also have to verify
that the cross-section of the electric
cables on the power point match the
appliance’s power rating.
– connect the blue wire to the terminal
marked with the letter N or coloured
black;
– connect the brown wire to the termi-
nal marked with the letter L or
coloured red.
Connection to a good earth wiring system
is absolutely essential.
The manufacturer accepts no responsibility
for any inconvenience caused by failure to
comply with this rule.
