Gas supply connection
• Check that the appliance is set for the type of gas
available and then connect it to the mains gas piping or
the gas cylinder in compliance with current regulations
and standards.
• This appliance is designed and set to work with the gas
indicated on the label situated on the actual hob. If the
gas supply is other than the type for which the appliance
has been set, proceed with replacing the corresponding
nozzles (provided), following instructions given in the
paragraph "Adaptation to different types of gas".
• For trouble-free operation, suitable use of energy and
longer life of the appliance, make sure that the supply
pressure complies with the values indicated in the table
1 "burners and nozzles specifications, otherwise install
a special pressure regulator on the supply pipe in
compliance with current standards and regulations.
• Connect in such a way that the appliance is subjected
to no strain whatsoever.
Either a rigid metal pipe with fittings in compliance with
the standards in force must be used for connecting to the
nipple union (threaded ½"G male fitting) situated at the
rear of the appliance to the right (fig.7), or flexible steel
pipe in compliance with the standards in force, which must
not exceed 2000 mm in length.
Should it be necessary to turn the fitting, the gasket
(supplied with the appliance) must be replaced.
Upon completion of installation, check the gas circuit, the
internal connections and the taps for leaks using a soapy
solution (never a flame).
Also check that the connecting pipe cannot come into
contact with moving parts which could damage or crush
it.
Make sure that the natural gas pipe is adequate for a
sufficient supply to the appliance when all the burners are
lit
Important: A pressure regulator, in compliance with the
standards in force, must be inserted when connecting to
a liquid gas supply (in a cylinder).
Adaptation to a different type of gas
If the hob is to be converted for use with a type of gas
other than that for which it was set in the factory (indicated
on the label to be found on the hob), the burner nozzles
should be replaced as follows:
• Remove the pan supports and the burners.
• Unscrew the nozzles "A" (fig.8) using a 7 mm socket
wrench and replace them with the ones which have a
diameter suitable for the type of gas to be used,
according to the table 1 "burners and nozzles
specifications).
• Reassemble the parts following the instructions in
reverse order.
Adjusting the low flame
• Put the tap to the low flame position;
• Remove the tap knob and turn the adjusting screw,
situated to the side of the tap stem (fig.9), using a
screwdriver (loosening the screw increases the height
of the flame, tightening decreases it).
note: the adjusting screw must be fully screwed down
for liquid gas.
• Having obtained the low flame setting required and with
the burner lit, abruptly change the position of the knob
several times from minimum to maximum and vice versa
and check that the flame does not go out.

Electrical connection
THE APPLIANCE MUST BE EARTHED
The hob is designed to work with alternating current at
the supply voltage and frequency indicated on the rating
plate (situated under the hob or at the end of the instruction
booklet). Make sure that the local supply voltage
corresponds to the voltage indicated on the rating plate.
Connecting the supply cable to the mains electricity
supply
For models supplied without a plug, fit a standard plug,
suitable for the load indicated on the rating plate, onto the
cable and connect to a suitable socket.
To connect directly to the mains supply, a double-pole
switch with a contact separation of at least 3 mm suitable
for the load and complying with current standards and
regulations, must be fitted between the appliance and the
mains supply outlet.
The yellow-green earth wire must not be interrupted by
the switch.
The supply cable must be in such a position that no part
