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.
Pass the power supply cable through the back of the unit, taking care that it does not
touch the bottom casing of the hob or the oven (if any) installed underneath it.
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
0.75 mm2(3 x 0.75 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

4. Gas connection
If the appliance is installed on an oven, the gas pipe must not be passed along the
back of the oven, as this may cause overheating.
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.
On models P705 and P64, for easier connection the union A on the back of the
appliance can be adjusted sideways. For this purpose, loosen hexagon nut B, turn
fitting Ato 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.
On model P106 the connection to the pipe must by made using a 90° union. The union
Hcannot be turned.
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. Adapting to different types of gas ”. The
gas intake fitting is ½” gas external threaded (ISO 228-1).
Connection with rigid copper pipe (P64/P705): 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 copper pipe and 90° union (P106):
the connection to the gas mains must not provoke stress
of any kind on the hob. The connection must be made
using a 90° F union, fitting the seal Cprovided in all
cases. Screw the union Fonto the gas train Hof the hob
using 2 spanners in opposite directions.
Connection with flexible pipe (All models): 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 Section “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.
