The connection should be suitable for
connecting to R 1/2 (1/2 BSP male
thread).
When the final connection has been
made, it is essential that a thorough leak
test is carried out on the hob and installa-
tion.
Make sure that the main connection pipe
does not exert any strain on the hob.
If you use flexible metal pipes make sure
that they agree to ISO 10380 and ISO
10807 standards. 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.
It is important to install the elbow
correctly, with the shoulder on the
end of the thread, fitted to the hob
connecting pipe.
Failure to ensure the correct as-
sembly will cause leakage of gas.
Make sure that the gas supply
pressure of the appliance obeys
the recommended values.
Rigid connection:
Carry out connection by using metal rigid
pipes (copper with mechanical end).

Injectors replacement
1.
Remove the pan supports.
2.
Remove the caps and crowns of the
burner.
3.
With a socket spanner 7 remove the
injectors and replace them with the
ones which are necessary for the type
of gas you use (see table in "Techni-
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.

The by-pass screw
• If you change from natural gas G20 20
mbar to liquid gas, fully tighten the by-
pass screw in.
• If you change from liquid gas to natural
gas G20 20 mbar, undo the by-pass
screw approximately 1/4 of a turn (1/2
of a turn for Triple Crown burner).
WARNING!
Make sure the flame does not go
out when you quickly turn the
knob from the maximum position
to the minimum position.
7.5
Electrical connection
• The electrical work necessary to install
the appliance must be done by a quali-
fied electrician or competent person,
according to the current regulations.
•
The appliance must be earthed.
• Always use a correctly installed shock-
