4 GAS CONNECTION

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.

To facilitate connection, fitting A on the rear of the appliance may be adjusted laterally. For this purpose, undo the hexagonal nut B, turn the union A into the position required and retighten the hexagonal nut B to a torque of at least 20 Nm. An annealed aluminium gasket provides the seal.

If the gasket is removed it may NOT be reused and must be replaced with another of exactly the same type.

Use a soapy solution to check for proper tightness. Never use a free flame.

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. ADJUSTMENT FOR DIFFERENT TYPES OF GAS”. The gas intake fitting is ½” gas external tapered thread (ISO 7-1).

Always place a suitable sealing medium (such as Teflon tape) between union A and pipe C/D.

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.

Connection with flexible pipe: use only flexible pipes conforming to standard regulations in force.

The flexible pipe has to be installed so that pipe length does not exceed the maximum extension allowed by the regulations in force. Make sure that the pipe does not touch any moving parts or become damaged.
