Read the appliance's instructions before
installing and using.
The graphics in these Assembly
instructions are given as a guide only.
The manufacturer is exempt from all
liability if this manual's requirements
are not complied with.
Safety instructions
All operations relating to installation,
regulation and conversion to other
types of gas must be carried out by
an authorised installation engineer,
respecting applicable regulations,
standards and the specifications of
the gas and electricity providers.
Before you begin, turn off the
appliance's electricity and gas
supply.
You are recommended to contact the
Technical Assistance Service to
convert to another type of gas.
This appliance has been designed for
home use only, not for commercial or
professional use. This appliance cannot
be installed on yachts or in caravans.
The warranty will only be valid if the
appliance is used for the purpose for
which it was designed.
Before installing, you need to check that
local distribution conditions (gas type
and pressure) and the appliance's
adjustment are compatible (see table I).
The appliance's adjustment conditions
are written on the label or the
specifications plate.
This appliance can only be installed in a
well-ventilated place in accordance with
existing regulations and ventilation
specifications. The appliance must not
be connected to a combustion product
evacuation device.
The supply cable must be attached to
the unit to prevent it from touching hot
parts of the oven or hob.
Appliances with electrical supply must
be earthed.
Do not tamper with the appliance's
interior. If necessary, call our Technical
Assistance Service.
Before installing
This appliance is class 3 type, according
to the EN 30-1-1 regulation for gas
appliances: built-in appliance.
The units next to the appliance must be
made of non-inflammable materials. The
laminated covering and glue for
adhering it must be heat resistant.
This appliance cannot be installed
above fridges, washing machines,
dishwashers or similar.
An oven must have power cooling fan to
install a hob above it.
Check the oven's dimensions in its
installation manual.
If an extractor fan is installed, you must
follow the installation manual's
instructions, always keeping a minimum
distance of 650 mm to the hob.
Preparation of unit (fig. 1-2)
Make a cut of an appropriate size in the
work surface.
If the hob is electric or mixed (gas and
electricity) and there is no oven below,
place a non-inflammable separator
(e.g.metal or plywood) 10 mm from the
bottom of the hob. This will prevent
access to the base of the hob. If the hob
is gas, it is recommendable to place the
separator at the same distance.
On wooden work surfaces, varnish the
cutting surfaces with a special glue to
protect them from moisture.
Installation of appliance
The clips and the adhesive seal
(underside of the hob) are factory-fitted,
do not under any circumstances remove
them. The seal ensures that the entire
work surface will be watertight, and
prevents water seepage. In order to fit
the appliance into the kitchen unit, first
place the hob in the correct position then
loosen each of the clips so that
they all turn freely (it is not necessary to
completely undo them). Fit and centre
the hob.
Press the sides of the hob until it is
supported around its entire perimeter.
Turn the clips and tighten them fully.
Fig. 3.
Removing the hob
Turn off the electricity and gas supply to
the appliance.
Unscrew the clips and proceed in the
reverse order to installation.
Gas connection (fig. 4)
The end of the inlet connection point of
the gas hob has a 1/2” (20.955 mm)
thread that allows for:
- rigid connection.
- connection using a flexible metal hose
(L min. 1 m - max. 3 m). With this option,
you must prevent the hose from coming
into contact with the moving parts of the
kitchen unit (for example, a drawer) or
accessing any spaces which might
become obstructed.
If you need to make a cylindrical
connection, replace the factory-fitted L-
tube with the one in the accessory bag.
Fig. 4a.
Please remember to insert the seal.
Warning! If any connection is handled,
check for tightness. Danger of leaks.
The manufacturer shall not be held liable
if any connection should leak, after
being handled.
Electric connection (fig. 5)
Check the voltage and power of the
appliance are compatible with the
electrical installation.
The hobs are supplied with a power
cable with or without a wall socket plug.
Provide an omnipolar cut-off switch with
a minimum contact gap of 3 mm (except
for plug connections, if the user has
access to it).
Appliances with plugs must only be
connected to sockets that have earth
wires correctly installed.
This appliance is type “Y”: the input
cable can only be changed by the
Technical Assistance Service and not
the user. The cable type and minimum
cross-section must be respected.
Changing the gas type
If the country’s regulations permit, this
appliance can be adapted to other types
of gas (see specifications plate). The
components necessary for this are in the
transformation kit supplied (according to
model). The kit is also available from our
Technical Assistance Service. The
following steps should be taken:
A) Changing the rapid, semi-rapid
and auxiliary burner nozzles (fig. 6):
- Remove the pan supports, the covers
and the gas burner casing.
- Change the burner nozzles using the
spanner provided by our Technical
Assistance Service (code 424699)
taking special care to ensure that the
burner nozzle does not fall when it is
removed from the burner or when fitted.
Ensure that they are completely
tightened in order to guarantee the seal.
Primary air adjustment is not necessary
with these burners.
B) Changing the double flame burner
nozzles (Fig. 7):
The glass panel and the frame are fixed
to the rest of the surface by means of
clips. The following steps must be taken
to remove both the glass panel and
frames:
- Remove the pan supports, covers, gas
burner casing, etc. Fig. 7a.
- Loosen the two screws on the rapid,
semi-rapid and auxiliary burners.
- Loosen the three screws on the double
flame burner. Fig. 7b - 7c.
- Use the disassembly lever 483196,
supplied by our technical services
department. To release the front clips,
use the lever at the points indicated in
figures 8, according to the hob model.
Never use the lever on the glass edges
which have no frame or trim!
- To release the rear clips, lift the glass
panel and frame carefully according to
Fig. 8.
Changing the outer flame nozzle.
Loosen the locking screw L1, fig. 9a, to
remove the bushing L2, backwards.
Remove the outer flame nozzle by
turning it towards the left.
Meanwhile, hold the nozzle housing.
Fig. 8b.
Screw in the new outer flame nozzle,
holding the nozzle housing in the
opposite direction.
Adjust the airflow adjusting bushing L2
according to the value -Z- shown in table
II. Tighten the locking screw L1.
Changing the inner flame nozzle.
Unscrew the part M3. from the threaded
part M2.
To do this, hold the threaded part in the
opposite direction. See Fig. N. Then
unscrew the threaded part M2. from part
M1, holding in the opposite direction.
See Fig. O.
Unscrew the inner flame nozzle M4 from
the part M2 and replace it with the
appropriate nozzle as indicated in table
II and adjust the airflow adjusting
bushing M5 according to the value -Y-
indicated in table II.
If the appliance is not securely fastened
or the clips are too rigid it may cause the
appliance to lift up. The procedure to be
followed in this situation is as follows:
1) Release the clips fixing the appliance
to the kitchen unit.
2) Loosen the main gas connection and
remove the appliance from its location.
