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 or 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.
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"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 appliance 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 grids and the burners.
•Unscrew the nozzles "A" (fig.9), using a 7 mm socket wrench and replace them, according to the table 1 "burners and nozzles specifications", with ones suitable for the new type of gas.
•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.
