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.8), 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.9) 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).
• 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.
Adjusting the low flame
• Put the tap to the low flame position (the burner should
be lit);
• Remove the tap knob (fig.10) and turn the adjusting screw,
situated to the side of the tap stem, 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 ver-
sa and check that the flame does not go out.
• Refit the tap knobs
If an electric fan is used for extracting the combustion
products, the ventilation aperture must be increased in
relation to its maximum performance. The electric fan
should have a sufficient capacity to guarantee an hourly
exchange of air equal to 3-5 times the volume of the kitchen.
Prolonged, intensive use of the appliance may require extra
ventilation, e.g. an open window or a more efficient
ventilation system by increasing the extraction power of
the electric fan if installed. Liquid petroleum gas descends
towards the floor as it is heavier than air. Apertures in the
outside walls in rooms containing LPG cylinders should
therefore be at floor level, in order to allow any gas from
leaks to be expelled. Do not store LPG cylinders (even
when empty) in basements/rooms below ground level; it is
advisable to keep only the cylinder in use in the room at
any one time and connected far from heat sources which
could raise its temperature to above 50°C.
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
The supply cable must be in such a position that no part of
it can reach a temperature of 50 °C above room temperature.
For installation above a built-under oven, the hob and the
oven must be connected separately to the electricity supply
both for safety reasons and for easy removal of the oven if
necessary. Do not use adapters or shunts as they could
cause heating or burning. Before connecting to the power
supply, make sure that:
• the limiter valve and the domestic system can withstand
the load from the appliance (see rating plate);
