Before installing
This appliance is class 3 type, according to the EN 30-1-1
regulation for gas appliances: built-in appliance.
The kitchen unit in which the appliance is installed must be
properly secured and stable.
The kitchen units next to the appliance, the laminated covering
and glue for adhering it must be made of non-flammable and
heat-resistant materials.
This appliance cannot be installed above fridges, washing
machines, dishwashers or similar.
An oven must have forced ventilation to install a hob above it.
Check the dimensions of the oven in the installation manual.
If an extractor fan is installed, you must follow the instructions in
the installation manual, always respecting the minimum vertical
distance from the hob (fig. 1).
Preparation of the kitchen unit (fig. 1-2)
Make an appropriate size cut in the worktop surface, depending
on the installation method. standard (a) or flush (b). For flush
installation:
■ All cuts in the worktop surface should be done by a
specialised shop.
■ The cuts should be clean and precise, as the cut edge is on
the surface. The stability of the furniture should also be
ensured after cutting work.
■ Use only specially designed work surfaces, resistant to high-
temperature and water (e.g. natural stone or tiled).
■ Surrounding furniture must be resistant to temperatures up to
90 °C.
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
A) Standard installation (fig. 3a)
Depending on the model, the adhesive seal may be factory-
fitted. If this is the case, it should not be removed under any
circumstances, since the adhesive seal prevents leaks. If the
seal has not been factory-fitted, apply it to the underside of the
hob.
Fitting the appliance onto the kitchen unit:
1. Remove the clips from the accessory bag and screw them into
the position indicated so that they can turn freely.
2. Insert and centre the hob.
Press the sides of the hob until it is supported around its entire
perimeter.
3. Turn the clips and tighten them fully.
The position of the clips depends on how thick the work
surface is.
B) Flush installation (fig. 3b)
1. Complete a normal installation of the appliance making sure
that it is surrounded by a uniform slot. The hob surface should
be slightly below the work surface.
For tile worktops, if necessary, raise the bearing surfaces with
strips resistant to water and temperatures.
2. Check the operation and position of appliance.
3. Fill the gap between the worktop and hob with conventional
silicone adhesive appropriate in the colour you desire.
Note: If unsuitable silicone adhesive is used on natural stone
surfaces then this can produce colours that can not be
removed. Our Technical Assistance Service can provide you
with the most suitable glue (code 310818). Please note the
manufacturers instructions for use.
4. Smooth the silicone adhesive with a scraper or wet finger
moistened with soap and water before it forms a layer.
5. Allow the silicone adhesive to dry before using the appliance.
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”
thread (20.955 mm) that allows for:
■ A fixed connection.
■ Connection using a flexible 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. 4.
You must prevent the pipe from coming into contact with
moving parts of the kitchen unit (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. 4a.
: Danger of leaks!
If any connection is handled, check the seal.
The manufacturer is not liable for any connection leaking, after
being handled.
Electric connection (fig. 5)
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.
The hobs are supplied with a power cable with or without a wall
socket plug.
Appliances with plugs must only be connected to sockets that
have earth wires correctly installed.
Provide an omnipolar cut-off switch with a minimum contact
opening of 3 mm (except for plug connections, if the user has
access to it).
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) or are available from our Technical
Assistance Service.
Important: After finishing, stick the sticker, indicating the new
gas type, close to the specifications plate.
The following steps should be taken:
A) Changing the nozzles (fig. 6):
1. Remove the pan supports, burner caps and diffusers.
2. Change the nozzles using the spanner code 340847 (code
340808 for double-flame burners or triple-flame burners)
provided by our Technical Assistance Service, see table II,
taking special care to ensure that the nozzle does not fall
when it is removed from or fitted to the burner.
Ensure that it is completely tightened in order to guarantee the
seal.
Primary air adjustment is not necessary with these burners.
3. Position the diffusers and burner caps on the corresponding
rings and the pan supports on their fasteners.
B) Adjusting the taps (Fig. 7):
1. Set the control knobs to minimum.
2. Remove the control knobs from the taps. It has a flexible
rubber valve reinforcing ring. Press with the tip of the
screwdriver to access the tap's adjusting screw.
Never remove the valve reinforcing ring. The valve reinforcing
rings guarantee the watertightness of the appliance's interior
from liquids and dirt, which might otherwise prevent its correct
operation.
3. Adjust the minimum ring setting by turning the by-pass screw
using a flat head screwdriver.
Depending on the gas to which your appliance is going to be
adapted, see table III, carry out the corresponding action:
A: firmly tighten the by-pass screws.
B: loosen the by-pass screws until the gas flow from the
burners is correct.
C: the by-pass screws need to be changed by an authorised
engineer.
D: do not touch the by-pass screws.
When adjusting the control knob between maximum and
minimum, the burner does not go out, nor is there a flame
backdraught created.
Never remove the tap spindle (Fig. 8). In the event of a
malfunction, change the whole tap.
