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
In the case of installation over a
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 temperature in excess of 50°C above room temperatu- re 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
•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 DifferentTypes 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.
Replacing the nozzles on separate “double flame “ burners:
•remove the grids and slide the burners from their housings. The burner consists of 2 separate parts (Fig. C and fig. D);
•unscrew the burers with a 7 mm wrench spanner. The internal burner has a nozzle, the external burner has two (of the same size). Replace the nozzle with models suited to the new type of gas (see table 1).
•replace all the components by repeating the steps in reverse order.

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
