2POSITIONING OF THE 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).
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 is classified as “type Y” in relation to fire hazards and
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 Aor B(supplied). Carefully trim any
excess from border Cof the gasket. The distances in the following
drawing refer to the hole on the inner side of the gasket.

2.2 Fixing 90 cm hobs on 60 cm base unit
If a 90 cm hob is to be bracketed to a 60 cm base unit, 2 central
brackets “A” have to be used in addition to the side brackets “B” as
shown in the drawing below. The gas connection also has to be turned
through 90° in relation to the original position(see paragraph 4 GAS
CONNECTION).

Instructions for the installer

3ELECTRICAL 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 mm 2 (3 x 1 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

4GAS 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 G25 (2L3B/P) natural gas at a pressure of 25 mbar. For use with
other types of gases, see Section “ 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 Aand 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 “5.3 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.

5ADAPTATION TO DIFFERENT TYPES OF GAS
Before performing any cleaning or maintenance work, disconnect the
appliance from the electrical socket.
The hob has been inspected for G25 (2L3B/P) natural gas at a
pressure of 25 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 separable control panel (models with
separable control panel)
1. Remove the knobs and the knob
guard tube “A” by pulling them up;
2. Use a crosshead screwdriver to
remove the screws and the two
cylindrical supports “B”;
3. Raise the left-hand side of the
control panel slightly and shift it to
the right to remove it completely;
4. In models with electric hotplate, the
body of the pilot light has to be
removed to free the control panel;
5. Raise the ignition crosspiece “C”
and rest it on the other side.
5.2 Removing the hob (models with integrated control
panel)
1. Remove the knobs, the
griddles, the burner caps, the
flame caps and the two rear
plugs;
2. Remove the screws “A” which
fix the burner supports;
3. Raise the hob, sliding it off the
ignition plugs and/or the
thermocouples and the gas
tap rods;
4. Lift the ignition crosspiece and
rest it on the other side.

5.3 Regulation for LPG
Check that the connection has been made as described in the “Gas
connection” section.
Undo the screw “D” and push the air regulator “C” fully down. Use a
spanner to remove the nozzles “B” and fit those of suitable type
following the instructions given in the tables for bottled gas G30/G31 –
28/37 mbar. The nozzle must not be tightened to a torque of over 3
Nm. Regulate the air flow by moving the Venturi pipe “C”, until the gap
“A” is as shown in the table in point “5.5 Regulation of primary air” and
fix it with the screw “D”. After making the adjustments, restore the
seals with sealing wax or an equivalent material.
