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.
