and
Flaring the Piping
1 Please cut using pipe cutter and then remove the burrs.
2 Remove the burrs by using reamer. If burrs is not removed, gas leakage may be caused.
Turn the piping end down to avoid the metal powder entering the pipe.
3 Please make flare after inserting the flare nut onto the copper pipes.
When properly flared, the internal
surface of the flare will evenly shine
and be of even thickness. Since the
flare part comes into contact with
the connections, carefully check
the flare finish.
