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 installation.
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.
CAUTION! It is important to install the
elbow correctly, with the shoulder on
the end of the thread, fitted to the hob
connecting pipe.
CAUTION! Failure to ensure the
correct assembly will cause leakage of
gas.
CAUTION! 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).
