8.1 Gas Connection
Choose fixed connections or use a flexible
pipe in stainless steel in compliance with
the regulation in force. If you use flexible
metallic pipes, be careful they do not
come in touch with mobile parts or they
are not squeezed. Also be careful when
the hob is put together with an oven.
Make sure that the gas supply
pressure of the appliance obeys
the recommended values.
If the supplied pressure has not the speci-
fied value, it is necessary to assemble a
proper pressure regulator in compliance
with the standard UNI EN 88. For Liquid
Gas (LPG) the use of pressure regulator is
allowed only if they are in compliance with
UNI EN 12864. The adjustable connection
is fixed to the comprehensive ramp by
means of a threaded nut G 1/2". Screw
the parts without force, adjust the con-
nection in the necessary direction and
tighten everything.

Rigid connection:
Carry out connection by using metal rigid
pipes (copper with mechanical end) (UNI-
CIG 7129).
Flexible connection:
Use a flexible pipe in stainless steel (UNI-
CIG 9891) with a maximum length 2 m.
When installation is complete,
make sure that the seal of each
pipe fitting is correct. Use a soapy
solution, not a flame!

2.
Remove the caps and crowns of the

3.
With a socket spanner 7 remove the
injectors and replace them with the

cal Information" chapter).
4.
Assemble the parts, follow the same
procedure backwards.
5.
Replace the rating plate (it is near the
gas supply pipe) with the one for the
new type of gas supply. You can find
this plate in the package supplied
with the appliance.
If the supply gas pressure is changeable
or different from the necessary pressure,
you must fit an applicable pressure ad-
juster on the gas supply pipe.
