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:

WARNIN S:
- burners fitted with safety cut-off devices can
only be lit when the knob is in the “Maximum”
position (big flame fig. 1).
- In the absence of electricity, the burners can
be lit with matches.
- Never leave the appliance unattended while
the burners are in use and ensure that
children are kept at a safe distance. Make sure
that pan handles are correctly positioned and
supervise the cooking of foods in oil and fat,
as these are highly flammable.
- The machine must not be used by people
(including children) with impaired mental or
physical capacities, or without experience of
using electrical devices, unless supervised or
instructed by an expert adult responsible for
their care and safety. Children should not be
allowed to play with the equipment.

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.

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.

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
burner.

The hob is equipped with a special seal to avoid
any infiltration of liquid into the unit. To apply this
seal correctly, please follow the instructions given
below carefully:
- remove all the mobile parts of the hob.
- Cut the seal into 4 strips of the lengths suitable to
fit it along the 4 sides of the glass.
- Turn the hob upside down and place the adhesive
side of the seal “E” (fig. 11) correctly under the
edge of the hob so that the outer edge of the seal
perfectly matches the outer perimeter edge of the
glass. The ends of the strips must match without
overlapping.
- Stick the seal to the glass evenly and securely,
using your fingers to press it into place.
- Position the hob in the hole in the unit and fasten it in
place using the appropriate screws “F” of the
fastening hooks “G” (see fig. 12 and fig. 13).
- In order to avoid accidental contact with the
surface of the box of the overheated hob during

IMPORTANT INSTALLATION
INSTRUCTIONS
The installer should note that the appliance that
side walls should be no higher than the hot plate
itself. Furthermore, the rear wall, the surfaces
surrounding and adjacent to the appliance must
be able to withstand an overtemperature of 65 K.
The adhesive used to stick the plastic laminate
to the cabinet must be able to withstand a
temperature of not less than 150 °C otherwise
the laminate could come unstuck. The appliance
must be installed in compliance with BS 6172
1990, BS 5440 part. 2 1989 and BS 6891 1988.
This appliance is not connected to a device able
to dispose of the combustion fumes. It must
therefore be connected in compliance with the
above mentioned installation standards.
Particular care should be paid to the following
provisions governing ventilation and aeration.
5) ROOM VE TILATIO
To ensure correct operation of the appliance, it is
important to ensure that the room where the hot
plate is installed has sufficient ventilation, as set out
in BS 5440 part 2. 1989. See table below.
Natural air flow must enter directly through
permanent openings in the walls of the room in
question. These must open towards the outside and
possess a minimum section of 100 cm2see fig. 3). It
must be impossible to obstruct these openings.
Indirect ventilation with air drawn from adjacent
rooms is permitted in strict compliance with the
provisions in force.
6) LOCATIO A D AERATIO
Gas cooking appliances must always dispose of
their combustion fumes through hoods. These must
be connected to flues, chimneys or straight outside
(see fig. 4). If it is not possible to install a hood, an
electric fan can be installed on a window or on a wall
facing outside (see fig. 5). This must be activated at
the same time as the appliance, so long as the
specifications in the provisions in force are strictly
complied with.
