Installation

! 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.

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

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.

• 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).

.

! 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.

When installing the cooktop above a built-in oven
without forced ventilation, ensure that there are air
inlets and outlets for ventilating the interior of the
cabinet adequately.

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.

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.
Sticker are available from any of our Service Centres.

Replacing the nozzles on separate “double flame “
burners:

1. remove the grids and slide the burners from their
housings. The burner consists of 2 separate parts (see
figure);

2. unscrew the burers with a 7 mm wrench spanner. The
internal burner has a nozzle, the external burner has
two (of the same size). Replace the nozzle with models
suited to the new type of gas (see table 1).

3. replace all the components by repeating the steps in
reverse order.

Replacing the Triple ring burner nozzles

1. Remove the pan supports and lift the burners out of
their housing. The burner consists of two separate parts
(see pictures).

2. Unscrew the nozzles using a 7 mm socket spanner.
Replace the nozzles with models that are configured
for use with the new type of gas (see Table 1). The two
nozzles have the same hole diameter.

3. Replace all the components by completing the above
operations in reverse order.

• Setting the burners to minimum:

1. Turn the tap to the low flame position.

2. Remove the knob and adjust
the adjustment screw, which is
positioned in or next to the tap
pin, until the flame is small but
steady.

3. Having adjusted the flame to the required low setting,
while the burner is alight, quickly change the position of
the knob from minimum to maximum and vice versa
several times, checking that the flame does not go out.

4. Some appliances have a safety device (thermocouple)
fitted. If the device fails to work when the burners are
set to the low flame setting, increase this low flame
setting using the adjusting screw.

5. Once the adjustment has been made, replace the seals
on the by-passes using sealing wax or a similar
substance.

! If the appliance is connected to liquid gas, the regulation
screw must be fastened as tightly as possible.

! Once this procedure is finished, replace the old rating
sticker with one indicating the new type of gas used.
Stickers are available from any of our Service Centres.

! Should the gas pressure used be different (or vary
slightly) from the recommended pressure, a suitable
pressure regulator must be fitted to the inlet pipe (in order
to comply with current national regulations).
