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 excee
d
the maximum extension allowed by the regulations in force. Make sur
e
that the pipe does not touch any moving parts or become damaged.
