burrs from cut edge. Make flare after inserting the flare nut
(located at valve) onto the copper pipe.
Align center of piping to valves and then tighten with torque
wrench to the specified torque as stated in the table.
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.
(1) *

Measure the pressure.
(2) *
*
Keep it for 5-10 minutes.
Ensure that the pressure indicated on the gauge is the
