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.
Electrical Connection
The cooktops fitted with a tripolar electrical supply cord
are designed to be be used with alternating current
according to the indications on the rating plate located
under the cooktop. The earthing wire can be identified by
its yellow-green colour.
In the case of installation over a built-in electric oven,
the electrical connections for the cooktop and oven
should be independent, not only for safety purposes, but
also to facilitate removal of one or both in the future.
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.
Important: the wires in the mains lead are coloured in
accordance with the following code:
Green & Yellow - Earth
Blue - Neutral
Brown - Live
As the colours of the wires in the mains lead may not
correspond with the coloured markings identifying the
terminals in your plug, proceed as follows:
Connect the Green & Yellow wire to the terminal marked
“E” or or coloured Green or Green & Yellow.
Connect the Brown wire to the terminal marked “L” or
coloured Red.
Connect the Blue wire to the terminal marked “N” or
coloured Black.
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 pan supports and slide the burners out of
the cooktop.
• 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
• Turn the gas valve to minimum.
• 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.
N.B.: In the case of liquid gas, the regulation screw must
be fully screwed in (clockwise).
• Make sure that, when the knob is turned rapidly high
to low, the flame does not go out.
• 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.
Once the adjustment has been made, apply sealing wax,
or a suitable substitute, to the old seals on the by-pass.
