replaced (supplied with the appliance).
The feeding connector of the gas to the appliance is
threaded 1/2 gas male cylinder.
Connection to flexible steel tube
The gas feed connector to the appliance is a threaded,
male 1/2" connector for round gas pipe. Only use pipes
and sealing gaskets that that conform to the standards
currently in force. The maximum length of the flexible pipes
must not exceed 2000 mm. Once the connection has been
made, ensure that the flexible metal tube does not touch
any moving parts and is not crushed.
Check the Seal
Once the appliance has been installed, make sure all the
connections are properly sealed, using a soapy water
solution. Never use a flame.
Electrical Connection
The hob is fitted with a 3x2.5 mm² power supply cable
factory set for a single-phase 220-230V~ connection. To
use a different type of connection, please refer to the
diagram below:
• Open the terminal box by removing the "V" screw and
taking off the cover.

• Connect the wires as shown in the diagram.

• Fix the cable in place with the "F" cable clamp, close
the lid and fasten it with the "V" screw.
Electrical Connection for Gas Cooktop
Fit the supply cord with a standard plug for the demand
rate indicated on the rating plate or connect it directly to
the electrical mains. In the latter case, a single pole switch
must be placed between the appliance and the mains,
with a minimum opening between the contacts of 3 mm in
compliance with current safety codes (the earthing wire
must not be interrupted by the switch). The power supply
cord must be positioned so that it does not reach a tem-
perature in excess of 50°C above room temperature at
any point.

Before making the actual connection, make sure that:
•
The fuse and electrical system can withstand the load
required by the appliance;
•
That the electrical supply system is equiped with an
efficient earth hook-up according to the norms and
regulations prescribed by law;
•
That the plug or switch is easily accessible.
N.B: Never use adaptors, shunts or the like because they
could overheat or cuase burns.
Attention: If the appliance is installed above a built-in
oven, the electrical connection for the cooktop must be
independent of that for the oven not only for safey reasons,
but also to facilitate removable of the oven in the future.
Adapting the Cooktop for Different Types of Gas
To adapt the cooktop to a different type of gas than that
for which it was designed, (see the sticker under the hob
or on the packaging), the burner nozzles must be changed,
as follows:
•
remove the grids and slide the burners from their
housings. The burner consists of 2 separate parts (Fig.
E and fig. F);
•
Unscrew the nozzles using a 7mm socket wrench and
replace them with those for the new type of gas. (See
table 1, "Burner and Nozzle Specifications").
•
Reassemble the parts following the instructions in
reverse order.
•
On completing the operation, replace the old rating label
with the one showing the new type of gas; the sticker
is available from our Service Centres.
If the gas pressure is different than that prescribed, a
pressure regulator must be installed at the source, in
compliance with national standards governing the use of
piped gas regulators.

Regulation of Air Supply to the Burner
The burners do not need a primary air regulator.
Minimum Regulation
Minimum regulation:
•
Turn the gas valve to minimum.
• Remove the knob and turn the regulator screw
clockwise until the flame becomes small but regular.
N.B.: In the case of liquid gas, the regulation screw must
be fully screwed in (clockwise).
