Installation
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
•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 "BSP male fitting) situated at the rear of the appliance to the right (fig.3), 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 leak- detection fluid. 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.4) 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.
•Reassemble the parts following the instructions in reverse order.

Minimum Regulation
•Turn the gas valve to minimum.
•Remove the tap knob and turn the adjusting screw, situated inside of the tap stem (fig.5), using a screwdriver (loosening the screw increases the height of the flame, tightening decreases it).
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
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.
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.
