!The installation instructions for cooking ranges shall
include a recommendation that such appliances
should not be placed adjacent to a door access to
minimise the likelihood of persons using the door
making contact with pans on the hob surface.
!Before operating your new appliance please read this
instruction booklet carefully. It contains important information
for safe use, installation and care of the appliance.
!Please keep these operating instructions for future
reference. Pass them on to possible new owners of the
appliance.
Positioning
!Keep packaging material out of the reach of children. It
can become a choking or suffocation hazard (see
Precautions and tips).
!The appliance must be installed by a qualified professional
according to the instructions provided. Incorrect installation
may cause harm to people and animals or may damage
property.
!This unit may be installed and used only in permanently
ventilated rooms in accordance with British Standard Codes
Of Practice: B.S. 6172 / B.S. 5440, Par. 2 and B.S. 6891
Current Editions. The following requirements must be
observed:
 The room must be equipped with an air extraction system
that expels any combustion fumes. This may consist of a
hood or an electric fan that automatically starts each time
the appliance is switched on.
 The room must also allow
proper air circulation, as air is
needed for combustion to occur
normally. The flow of air must not
be less than 2 m3/h per kW of
installed power.
The air circulation system may
take air directly from the outside
by means of a pipe with an inner
cross section of at least 100 cm2;
the opening must not be
vulnerable to any type of
blockages.
The system can also provide the
air needed for combustion
indirectly, i.e. from adjacent rooms
fitted with air circulation tubes as described above.
However, these rooms must not be communal rooms,
bedrooms or rooms that may present a fire hazard.
 Liquid petroleum gas sinks to the floor as it is heavier
than air. Therefore, rooms containing LPG cylinders must
also be equipped with vents to allow gas to escape in the
event of a leak. As a result LPG cylinders, whether
partially or completely full, must not be installed or stored
in rooms or storage areas that are below ground level
(cellars, etc.). It is advisable to keep only the cylinder
being used in the room, positioned so that it is not
subject to heat produced by external sources (ovens,
fireplaces, stoves, etc. ) which could raise the
temperature of the cylinder above 50°C.
Fitting the appliance
Gas and mixed hobs are manufactured with type X degree
protection against overheating. The following precautions
must be taken when installing the hob:
 Kitchen cabinets adjacent to the appliance and taller
than the top of the hob must be at least 600 mm from the
edge of the hob.
 Hoods must be installed according to their relative
installation instruction manuals and at a minimum
distance of 650 mm from the hob.
 Place the wall cabinets adjacent to the hood at a
minimum height of 420 mm from the hob (see figure).
If the hob is installed beneath a
wall cabinet, the latter must be
situated at a minimum of 700 mm
above the hob (see figure).
 The installation cavity should have the dimensions
indicated in the figure.
Fastening hooks are provided, allowing you to fasten the
hob to tops that are between 20 and 40 mm thick. To
ensure the hob is securely fastened to the top, we
recommend you use all the hooks provided.

!Use the hooks contained in the accessory pack
 Where the hob is not installed over a built-in oven, a
wooden panel must be installed as insulation. This must
be placed at a minimum distance of 20 mm from the
lower part of the hob.
Ventilation
To ensure adequate ventilation, the back panel of the
cabinet must be removed. It is advisable to install the oven
so that it rests on two strips of wood, or on a completely flat
surface with an opening of at least 45 x 560 mm (see
diagrams).
!The hob can only be installed above built-in ovens with a
cooling ventilation system.
Gas connection
The appliance should be connected to the main gas supply
or to a gas cylinder in compliance with current national
regulations. Before carrying out the connection, make sure
the cooker is compatible with the gas supply you wish to
use. If this is not the case, follow the instructions indicated in
the paragraph Adapting to different types of gas.
When using liquid gas from a cylinder, install a pressure
regulator which complies with current national regulations.
!Check that the pressure of the gas supply is consistent
with the values indicated in Table 1 (Burner and nozzle
specifications). This will ensure the safe operation and
longevity of your appliance while maintaining efficient
energy consumption.
Connection with a rigid pipe (copper or steel)
!Connection to the gas system must be carried out in such
a way as not to place any strain of any kind on the
appliance.
There is an adjustable L-shaped pipe fitting on the
appliance supply ramp and this is fitted with a seal in order
to prevent leaks. The seal must always be replaced after
rotating the pipe fitting (seal provided with appliance). The
gas supply pipe fitting is a threaded 1/2 gas cylindrical male
attachment.
Connecting a flexible jointless stainless steel pipe to a
threaded attachment
The gas supply pipe fitting is a threaded 1/2 gas cylindrical
male attachment.
These pipes must be installed so that they are never longer
than 2000 mm when fully extended. Once connection has
been carried out, make sure that the flexible metal pipe
does not touch any moving parts and is not compressed.
!Only use pipes and seals that comply with current national
regulations.
Checking the tightness of the connection
!When the installation process is complete, check the pipe
fittings for leaks using a soapy solution. Never use a flame.
Adapting to different types of gas
To adapt the hob to a different type of gas other than default
type (indicated on the rating plate at the base of the hob or
on the packaging), the burner nozzles should be replaced
as follows:
1. Remove the hob grids and slide the burners off their
seats.
2. Unscrew the nozzles using a 7 mm socket spanner, and
replace them with nozzles for the new type of gas (see
table 1 Burner and nozzle characteristics).
3. Reassemble the parts following the above procedure in
the reverse order.
4. Once this procedure is finished, replace the old rating
sticker with one indicating the new type of gas used.

To switch off the burner, turn the knob in a clockwise
direction until it stops (when reaches the  position).
The "double-flame" burner*
This gas burner consists of two concentric flame
rings. Using both flame rings enables a higher power
level to be reached, thus reducing cooking time with
respect to the time required by traditional burners. The
double ring also enables heat to be distributed across
the base of the pan more evenly.
Cookware of all sizes may be used; when cooking
with small recipients use only the inner burner. The
burner is controlled with a single knob.
To light it, press the knob in fully and turn it in an
anticlockwise direction until it reaches the maximum
position . The burner is equipped with an electronic
lighting system that is activated automatically when
the knob is pressed.
As the burner is fitted with a safety device, the knob
should be held down for approximately 2-3 seconds,
until the automatic device keeping the flame alight has
heated up.
Each burner can be adjusted using the control knob
as follows:
 Off
On and inner ring set to maximum
Inner ring set to minimum
Both rings set to maximum
Both rings set to minimum
To switch off the burner, turn the knob in a clockwise
direction until it stops (when it reaches the  position).
Practical advice on using the burners
To ensure the burners operate efficiently:
 Use appropriate cookware for each burner (see
