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 G25 (2L3B/P) natural gas at a pressure of 25 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
(ISO 7-1).
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 1.5 meters of maximum extension. Make sure that the pipes do
not touch any moving parts or become damaged.
