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 228-1).
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 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.
