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.

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
