Instructions for the installer
4. Gas connection
If the appliance is installed on an oven, the gas pipe must not be passed along the back of the oven, as this may cause overheating.
Connection to the gas mains may be made with a rigid copper pipe or with a flexible pipe and conforming to the provisions defined by standard regulations in force.
On some models, for easier connection the union A on the back of the appliance can be adjusted sideways. For this purpose, loosen hexagon nut B, turn fitting A to the desired position, and retighten hexagon nut B (tightness is ensured by a biconical brass ring). Use a soapy solution to check for proper tightness. Never use a free flame. On some model the connection to the pipe must by made using a 90° union. The union H cannot be turned.
The hob has been inspected for G20 (2H) natural gas at a pressure of 20 mbar. For use with other types of gases, see Section “5. Adapting to different types of gas ”. The gas intake fitting is ½” gas external threaded (ISO
Connection with rigid copper pipe: the connection to the gas mains must not provoke stress of any kind on the hob. Connection may be made by using biconical adapter D with insertion of gasket C (supplied).
Connection with copper pipe and 90° union (only on some models): the connection to the gas mains must not provoke stress of any kind on the hob. The connection must be made using a 90° F union, fitting the seal C provided in all cases. Screw the union F onto the gas train H of the hob using 2 spanners in opposite directions.
Connection with flexible pipe (All models): use only flexible pipes conforming to standard regulations in force, inserting gasket C (supplied) between fitting A and flexible pipe E.
The flexible pipe has to be installed so that pipe length does not exceed 1.5 meters of maximum extension. Make sure that the pipes do not touch any moving parts or become damaged.
