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.
2.1.1 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.
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
Bof the gasket. The distances in the following drawing refer to the hole
on the inner side of the gasket.

Instructions for the installer
26
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.
(Only for 90 cm models) Installation of an oven without cooling fan
underneath the hob is forbidden.

Instructions for the installer
27
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 Aon 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 ½” gas external threaded (ISO 228-1).
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 Dwith 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.
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.

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. lift the hob from its seat;
4. replace the burner nozzles in accordance with the reference gas
chart;
5. regulate the primary air as described in paragraph “5.2 Regulation
for LPG”.

Instructions for the installer
31
5.2 Regulation for LPG
Loosen screw Aand push support Ball the way. Use a double head
wrench to remove nozzle Cand assemble the suitable one, following the
instructions indicated in the reference charts, with respect to the type of
gas to use. The screwing torque of the nozzle should never exceed
3 Nm. Reposition support Bso that nozzle Cis covered perfectly.
Move the Venturi tube Dto regulate the air flow until distance "X" is
reached indicated in the chart in paragraph "5.4 Regulation of primary air”
and then secure the tube by means of screw A. After the regulations
have been carried out, restore the seals with sealing wax or equivalent
material.
