1) TRADITIO AL BUR ERS
On the surface of the hob, there is a serigraphic
figure above each knob, indicating the burner to
which the knob refers. After turning on the gas at
the main or opening the valve on the gas bottle,
light the burners as indicated below:
- automatic electric ignition
Press the knob corresponding to the burner to use
and turn it clockwise to the “Maximum” position
(big flame fig. 1) pressing the knob right down.
- Lighting burners fitted with a safety cut-off
device
For burners fitted with a safety cut-off device, turn
the knob corresponding to the burner to use anti-
clockwise to the “Maximum” position (big flame
fig. 1) until it stops and then press the knob.
Continue pressing the knob for about 10 seconds
after the burner has been lit.
Should the flames accidentally go out, turn the
burner control knob off and wait at least 1 min befor
attempting to light it again.
How to use the burners
To obtain maximum performance with minimum gas
consumption, remember the following:
- use suitable pans for each burner (see the table
below and fig. 2).
- When boiling point is reached, turn the knob to the
“Minimum” position (small flame fig. 1).
- Always use pans with lids.
“DUAL” burner:
separate regulation of the inner and outer rings (in
practical terms, a dual burner controlled by a single
knob), offering very flexible use thanks to the
possibility to light either the inner flame only or the
whole burner (inner and outer flame at the same
time).
LIGHTI G A D USI G THE “DUAL” BUR ER
Stand the pan on the burner before lighting.
Despite being controlled by a single knob, the
“DUAL” burner can be used in two different ways.
A) - Using the complete burner:
starting from the off position ● You must first press
the knob, simultaneously turning it anti-clockwise,
until the indicator points to the maximum delivery
position obtaining the maximum flow capacity of
both flames.
When the flames are lit, keep the knob pressed for
a few seconds, until the device automatically keeps
the burner lit.
It is now possible to regulate the intensity of the
flame by turning the knob anti-clockwise (from the
maximum flow capacity position of the inner and
outer flames to the maximum flow capacity of the
inner flame and the minimum of the outer flame.
To turn off the burner, turn the knob clockwise,
realigning the indicator with the ● off symbol.
B) - Using the inner flame only:
after lighting the burner and regulating the inner
flame to maximum flow capacity and the outer
flame to minimum flow capacity as described
above, turn the knob anti-clockwise until it clicks
once. The inner flame is now at maximum flow
capacity while the outer flame is turned off.
Continue turning anti-clockwise to regulate the inner
flame to the minimum flow capacity.
Turning off:
to turn off the burner, turn the knob clockwise,
realigning the indicator with the ● off symbol.
Once the “DUAL” burner is operating in either of the
two modes described, it is possible to swap from
one mode to the other by simply pressing and
turning the knob to the position required:

USE
Notes:
the use of a gas hob produces heat and humidity in the room where it is installed. Consequently, the
room must be well aired, keeping natural ventilation openings free (fig. 3) and activating the
mechanical aeration device (suction hood or electric fan fig. 4 and fig. 5).
Intensive and prolonged use of the appliance may require extra aeration, such as the opening of a
window, or more effective aeration, increasing the mechanical suction power where this exists.

CLEA I G
CAUTION:
before cleaning the appliance, disconnect it
from the gas and electricity supplies.
2) WORKTOP
If you wish to maintain the shine of the ceramic
surface, treat the glass with a silicon-based film
product before use to protect the surface against
water and dirt. This protective film is not durable,
so it is advisable to repeat the application of the
product frequently.
It is very important to clean the hob every time you
use it, while the glass is still warm.
Do not clean using abrasive metal scourers, powder
abrasives or corrosive sprays.
Depending on the degree of dirt, we recommend:
- for light stains, a damp sponge is sufficient.
- Tough, encrusted dirt is easily eliminated using a
scraper (fig. 6), not supplied with the hob, but
easy to find in local stores. Use the scraper
carefully to avoid damaging the hob.
- Traces of liquid spilled from pans can be
eliminated with vinegar or lemon juice.
- Never allow sugar or sugary foods to fall on the
hob while cooking. Should this occur, switch off
the hob and clean it immediately with hot water,
using a scraper on hot spills.
- As time goes by metallic reflections, colouring or
scratches may appear due to poor cleaning and
the incorrect movement of pans. Scratches are
hard to eliminate but do not affect the correct
operation of your hob.
- Do not use jets of steam to clean the appliance.

CLEA I G
The enamelled grids, enamelled covers “A”, “B” and
“C”, and burner heads “M” (see fig. 7 and 7/A) must
also be washed and the ignition elements “AC” and
safety cut-off sensors “TC” (see fig. 7/B) must be
cleaned. Do not wash them in the dishwasher.
Cleaning operations must be carried out when the
hob and components are not hot and the use of
metal scouring pads, powder abrasives and
corrosive sprays must be avoided.
Do not allow vinegar, coffee, milk, salt water, lemon
juice or tomato juice to remain in prolonged contact
with the surfaces.
WARNIN S:
when reassembling the components, observe
the following recommendations:
- check that the holes in the burner heads “M”
(fig. 7) are not blocked by foreign bodies.
- Ensure that the enamelled covers “A”, “B”
and “C” (fig. 7and 7/A) are correctly positioned
on the burner head. The covers are correctly
positioned on the head when they are
perfectly stable.
- If the opening and closing of any valve is
awkward, do not force it but request urgent
intervention by the technical assistance
service.
- Do not use jets of steam to clean the
appliance.
- To prevent difficulties with lighting, regularly
clean the ignition elements (ceramic and
electrode) and safety cut-off devices.
IMPORTANT:
when removing the burners to clean them, ensure
that all parts are correctly positioned before
relighting them. In particular for the “Dual” burner,
never remove the central disc underneath the
lid (particular A - fig. 8), for cleaning. Should this
operation be necessary, it must be carried out
exclusively by qualified personnel.
Do not remove the metal disc “B” screwed onto the

REGULATIO
Before performing any regulation, disconnect
the electricity supply to the appliance.
After carrying out any regulation or pre-
regulation operations, any seals must be
replaced by the technician.
The regulation of primary air to our burners is
not necessary.
9) VALVES
Regulation of the “Minimum”:
- light the burner and turn the knob to the “Minimum”
position (small flame fig. 1).
- Remove the knob “M” (fig. 14) of the valve, which
is simply pressed onto the post.
- Insert a small screwdriver “D” into the hole “C”
(fig. 14) and turn the closing screw either right or
left until the burner flame is conveniently regulated
to the “Minimum”.
Ensure that the flame does not go out when
switching quickly from the “Maximum” position to
the “Minimum” position.
It is understood that the aforementioned
regulation must only be carried out with burners
which use 20, while for burners which use 30
or 31 the screw must be blocked completely.
In the case of a “DUAL” burner, the regulation
screw situated inside the post of the valve regulates
the central flame, while the screw next to the valve
regulates the outer flame.
The operations described above can be carried out
easily, whatever the position of the hob or however
it is fastened to the unit.
THE BUR ERS DO OT REQUIRE A Y

TRA SFORMERS
10) REPLACI G OZZLES
The burners can be adapted to suited different
types of gas by fitting the nozzles that correspond to
the gas used. To do this, it is necessary to remove
the burner heads and use a straight key “B”, to
unscrew the nozzle “A” (see fig. 15) and replace it
with a nozzle corresponding to the gas used.
We advise you to block the nozzle tightly.
After making these replacements, the technician
must regulate the burners as described in
paragraph 9, seal any regulation or pre-
regulation organs and apply the label
corresponding to the new gas regulation carried
out on the appliance in place of that previously
applied. This label is contained in the spare
nozzle bag.
For the ease of the fitter, we have prepared a table
indicating the flow capacities, the heat capacities of
the burners, the diameter of the nozzles and the
