Installation

GB

! 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.

In a chimney stack or branched flue.
(exclusively for cooking appliances)

• 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 m
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

The system can also provide
the air needed for combustion
indirectly, i.e. from adjacent
rooms fitted with air circulation
tubes as described above.

Enlarging the ventilation slot
between window and floor.

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 (

figure

).

see

If the hob is installed beneath
a wall cabinet, the latter must

600mm min.

700mm min.

be situated at a minimum of
700 mm above the hob (

figure

600mm min.

).

see

• 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

560 mm.

).

45 mm.

Where a hob is installed above an oven without a
forced ventilation cooling system, adequate
ventilation must be provided inside the cabinet by
means of air holes through which air can pass (

figure

).

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

LL

on the appliance. There is an adjustable
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. Sticker are available from any of our
Service Centres.

• Adjusting the burners’ primary air :

Does not require adjusting.

! 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).

• 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.
