Gas Connection
The cooktop should be connected to the gas supply
by an authorized installer. During installation of this
product it is essential to fit an approved gas tap to
isolate the supply from the appliance for the
convenience of any subsequent removal or servicing.
Connection of the appliance to the gas mains or liquid
gas tanks must be carried out according to the safety
standards currently in force, and only after it is
ascertained that it is suitable for the type of gas to be
used. If not, follow the instructions indicated in the
section entitled, “Adapting the Cooktop for Different
Types of Gas”. If the cooktop is to be connected to
tanks containing liquid gas, use pressure regulators
that comply with current safety standards.
 To insure that the appliance operates safety, the gas
is regulated correctly and your appliance lasts over
time, make sure that gas pressure levels comply with
the indications given in Table 1, “Nozzle and Burner
Specifications”.
Gas Connection to Non-flexible Pipe
(copper or steel)
 Connection to the gas source must be done in such
a way as to not create any stress points at any part of
the appliance.
The appliance is fitted with an adjustable, "L" shaped
connector and a gasket for the attachment to the gas
supply. Should this connector have to be turned, the
gasket must be replaced (supplied with the
appliance).
The gas feed connector to the appliance is a
threaded, male 1/2" connector for round gas pipe.
Gas Connection to Flexible Steel Pipe
The gas feed connector to the appliance is a
threaded, male 1/2" connector for round gas pipe.
Only use pipes, tubes and gaskets that comply with
current safety codes. 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.
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:
1. Remove the pan supports and slide the burners out
of the cooktop.
2. 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”).
3. Reassemble the parts following the instructions in
reverse order.
4. 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.
• Regulation of Air Supply to the Burner
The burners do not need a primary air regulator.
• Minimum Regulation
1. Turn the gas valve to minimum.
2. Remove the knob
and turn the regulator
screw (positioned either
on the side of the top or
inside the shaft)
clockwise until the flame
becomes small but
regular.
3. Make sure that, when the knob is turned rapidly
high to low, the flame does not go out.
4. In the event of a malfunction on appliances with the
security device (thermocouple) when the gas
supply is set at minimum, increase the minimum
supply levels using the regulator screw.
 In the case of liquid gas, the regulation screw must
be fully screwed in (clockwise).
 Once the adjustment has been made, apply sealing
wax, or a suitable substitute, to the old seals on the
by-pass.
