Connecting a flexible jointless stainless steel pipe to a

threaded attachment

The gas supply pipe fitting is a threaded 1/2 gas

cylindrical male attachment.

These pipes must be installed so that they are never

longer than 2000 mm when fully extended. Once

connection has been carried out, make sure that the

flexible metal pipe does not touch any moving parts and

is not compressed.

! Only use pipes and seals that comply with current

national regulations.

Checking the tightness of the connection

! When the installation process is complete, check the

pipe fittings for leaks using a soapy solution. Never use a

flame.

! Should the gas pressure used be different (or vary

slightly) from the recommended pressure, a suitable

pressure regulator must be fitted to the inlet pipe (in order

to comply with current national regulations).
