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.
These individual appliances can be
combined with other identical
appliances and/or with conventional
hobs of the same make, using the joint
accessory.
See the catalogue for details.
The units next to the appliance must be
made of non-flammable 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 a 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 kitchen unit
(fig. 1-2)
Make an appropriate size cut in the
work surface.
If the hob is electric or mixed (gas and
electricity) and there is no oven below,
place a non-flammable 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 wood work surfaces, varnish the
cutting surfaces with a special glue.
This protects them from moisture
which could collect under the work
surface.
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).
Insert 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
Removal of hob
Turn off the appliance's electricity and
gas supply.
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:
- fixed connection.
- connection using a flexible metal pipe
(L min. 1 m - max. 3 m). In this case, it
is necessary to insert the accessory
(427950) and the watertight seal
(034308) supplied between the
manifold outlet and the gas supply.
Fig. 4a.
In this case, you must prevent the pipe
from coming into contact with moving
parts of the kitchen unit being inserted
(for example, a drawer) and prevent
access to any spaces which might
become obstructed.
If you need to connect the gas supply
horizontally, our Technical Assistance
Service can supply you with an L-tube
(code 173018) and a seal (code
034308). Fig. 4b.
Warning! If any connection is handled,
check the seal.
Danger of leaks.
The manufacturer is not liable for any
connection leaking, after being
handled.
Electric connection (fig. 5)
Check that 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 separation 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 supply
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 allow, this
appliance can be adapted to other
types of gas (see specifications plate).
The components required for this are
in the transformation kit supplied
(depending on the model) available
from our Technical Assistance Service.
The following steps should be taken:
A) Changing the nozzles of the rapid,
semi-rapid and auxiliary burners on
the hob (fig. 6):
- Remove the pan supports, burner
covers and diffusers.
- Change the nozzles using the
spanner provided by our Technical
Assistance Service (code 424699),
taking special care to ensure that the
nozzle does not fall when it is removed
from the burner or when fitted.
Ensure that it is completely tightened in
order to guarantee the seal. Primary air
adjustment is not necessary with these
burners.
B) Changing the nozzles for double-
flame burners (fig. 7):
The glass panel and frame are fixed to
the rest of the hob using a clip
mounting system. The following steps
must be taken to remove the glass
panel and frame:
- Remove all the burner covers and pan
supports. Fig. 7a.
- Release the front clip fixing the
appliance to the kitchen unit by
removing the screw. Fig. 7b.
- Loosen the screws on the burners,
fig. 7c-7d, and remove the control
knobs from their respective housings.
Use the disassembly lever 483196
available from our Technical
Assistance Service. To release the
front clips, apply the lever in the area
shown in figures 8 according to the
hob model.
Never use the lever on glass edges
which have no trim or frame!
- To release the rear clips, carefully
raise the entire glass panel and frame,
as in fig. 8a.
Changing the outer flame nozzle
(fig. 9a):
- Loosen the clamp screw to release
the bushing by moving it backwards to
access the main nozzle easily. Fig. a1.
- Remove the outer flame nozzle by
turning it towards the left. Fig. a2-a3.
