Cutting/Flaring the Pipes

ENGLISH

Connect the pipe within 30m(100ft) and cutting pieces will not be gone

into the pipe as being clean to pipe section.

1Make sure that you have the required tools available (pipe cutter, reamer, flaring tool and pipe holder).

2If you wish to shorten the pipes, cut it with a pipe cutter, taking care to ensure that the cut edge remains at a 90° angle with the side of the pipe. Refer to the illustrations below for examples of edges cut correctly and incorrectly.

3To prevent any gas from leaking out, remove all burrs at the cut edge of the pipe, using a reamer.

4Slide a flare nut on to the pipe and modify the flare.
