Decide piping length and then cut by using pipe cutter.
Remove burrs from cut edge.
Make flare after inserting the flare nut (locate at valve)
onto the copper pipe. Align center of piping to valve
and then tighten with torque wrench to the specified
torque as stated in the table.
Do not overtighten, overtightening may cause gas leakage.

12.2.5.4 Cutting 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 fl ared, the internal surface of the
fl are will evenly shine and be of even thickness.
Since the fl are part comes into contact with the
connections, carefully check the fl
are fi nish.
