ACutting/flaring the pipes
1. Make sure that you have the required tools available (pipe cutter, reamer,flaring tool and pipe holder).
2. If you wish to shorten the piping, cut it using a pipe cutter, taking care to ensure that the cut edge remains at a
90° angle with the side of the pipe,and referring to the illustrations below for examples of edges cut correctly and
incorrectly.
3. To prevent any gas from leaking out, remove all burrs at the cut end of the pipe, using a reamer.
4. Slide a flare nut on to the pipe and modify the flare.
5. Check that the flaring is correct, referring to the illustrations below for examples of incorrect flaring.
6. Align the pipes to be connected and tighten the flare nuts first manually and then with a torque wrench,
applying the following torque.
