Instructions for the installer
2. POSITIONING OF HOB
The following operation requires building and/or carpentry work so
must be carried out by a competent tradesman.
Installation can be carried out on various materials such as
masonry, metal, solid wood or plastic laminated wood as long as
they are heat resistant (T 90°C).
Never use silicone or other insulating products when installing the
appliance; use only the rubber gasket provided.
2.1. Attachment to support structure
Create an opening with the dimensions shown in the figure in the
top surface of the counter, keeping a minimum distance of 50 mm
from the rear border. This appliance can therefore be mounted
against walls higher than the work surface on condition that a
certain distance “X” be kept between the appliance and the wall as
shown in the figure so as to avoid damage from overheating.
Make sure there is a minimum of 750 mm between the hot plate
flames and any shelf that may be installed directly above them.
Instructions for the installer
Accurately position the gasket provided all around the outer edge of
the hole in the top surface as shown in the figures below, pressing it
down so as to make it adhere properly. For measurements, refer to
the figure depending on the hob model to be installed, bearing in
mind that in both models the front and rear sides must skim the hole.
Secure the hob to the counter with brackets A (supplied). Carefully
trim any excess from border B of the gasket. The distances in the
following drawing refer to the hole on the inner side of the gasket.
In case of installation on a hollow compartment with doors, a
separating panel has to be placed under the hob. Keep a minimum
distance of 10 mm between the bottom of the unit and the panel
surface. The panel has to be easily removable to allow access in
the event of technical service.

3. Electrical connection
Make sure that the voltage and capacity of the power line conform
to the data shown on the plate located under the casing. Do not
remove this plate for any reason.
The plug on the end of the supply cable and the wall socket must
be the same type and conform to the current electrical system
regulations. Check that the power line is adequately grounded.
On the power line, install an omnipolar cut-off device with contact
cut-off distance greater than or equal to 3 mm, located in an easily
accessible position near the unit.
Do not use reducers, adapters or shunts.
If the power cable is replaced, the wire section on the new cable
must not be less than 1.5 mm2 (3 x 1.5 cable), keeping in mind
that the end to be connected to the hob must have the ground
wire (yellow-green) longer by at least 20 mm. Use only
H05V2V2-F cable or similar which has a maximum temperature
of 90°C. Any replacement needed should be carried out by a
specialised technician who should make the mains connections
according to the following diagram.
L = brown
N = blue
= yellow-green
The manufacturer will not be liable for any damage to persons or
property caused by non-observance of the above instructions or
deriving from the tampering of even a single part of the hob.
Instructions for the installer
4. GAS CONNECTION
Connection to the gas mains may be made with a rigid copper pipe
or with a flexible pipe and conforming to the provisions defined by
standard regulations in force.
To facilitate connection, fitting A on the rear of the appliance may be
adjusted laterally. For this purpose, loosen hexagon nut B, turn
fitting A to the desired position, and retighten hexagon nut B
(tightness is ensured by a biconical brass ring). Use a soapy
solution to check for proper tightness. Never use a free flame.
The hob has been inspected for G20 (2H) natural gas at a pressure
of 20 mbar. For use with other types of gases, see Section “5.
ADAPTATION TO DIFFERENT TYPES OF GAS”. The gas intake
fitting is 1/2gas external threaded (ISO 228-1).
8
The flexible pipe has to be installed so that pipe length does not
exceed 1.5 meters of maximum extension. Make sure that the pipes
do not touch any moving parts or become damaged.
Connection with rigid copper pipe:
the connection to the gas mains must
not provoke stress of any kind on the
hob.
Connection may be made by using
biconical adapter D with insertion of
gasket C (supplied).
Connection with flexible pipe: use
only flexible pipes conforming to
standard regulations in force, inserting
gasket C (supplied) between fitting A
and flexible pipe E.

4.1 Connection to LPG
Use a pressure regulator and make the connection to the tank
according to the provisions of standards regulations in force. Make
sure that feed pressure conforms to the levels shown in the table in
paragraph “5.2 Regulation for LPG”.
4.2 Ventilation of rooms
The hob may be installed only in rooms with permanent ventilation,
as required by standards regulations in force. The room in which
the hob is installed must have sufficient air flow to satisfy the
requirements of normal gas combustion and of necessary air
exchange in the room. The air intakes, protected by screens, must
be appropriately sized (regulations in force) and placed so as not to
be blocked in any way. The room where the oven is installed should
be suitably ventilated to avoid overheating or excess humidity
produced by cooking, and in the case of lengthy use a window
should be opened or the speed of any ventilators should be
increased.
4.3 Discharge of combustion products
Discharge of combustion products must be guaranteed by means of
hoods connected to a natural draught flue with certain efficiency, or
by means of forced aspiration.
An efficient aspiration system requires careful planning by a
specialist capable of installing it, respecting the positions and
distances prescribed by standards. After installation, the installer
must issue a certificate of conformity.
5.
ADAPTATION TO DIFFERENT TYPES OF GAS
Before performing any cleaning or maintenance work, detach
the appliance from the electrical socket.
The hob has been inspected for G20 (2H) natural gas at a
pressure of 20 mbar. For functioning with other types of gas the
nozzles must be replaced and the primary air adjusted.
To replace the nozzles and regulate the burners, you have to
remove the top as described in the following paragraph.
5.1 Removing the hob
1. Remove all the knobs, the grids, the burner caps and the flame-
caps;
2. remove the screws and the nuts Athat secure the burner
supports;
3. remove plates B;
4. lift the hob from its seat;
5. replace the burner nozzles in accordance with the reference gas
chart;
6. regulate the primary air as described in paragraph “5.2
Regulation for LPG”.
