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, 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. 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 “ ADAPTATION TO DIFFERENT TYPES
OF GAS”. The gas intake fitting is ½” gas external threaded.
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 flexible pipe: 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 2 meters of maximum extension. Make sure that the pipes do
not touch any moving parts or become damaged.
