2.3.6.2. Diameter of supply pipe

Ensure that the diameter and length of the natural gas pipe complies with the requirements given in figures 2.17 and 2.18. Measure
the length of the pipe between the main pressure regulator and the generating set inlet pipe union. Add 2.40 m to the length
measured for each 90° bend. Compare the length and diameter of the pipe with the measurements given in the table in figures 2.17
and 2.18. If the pipe diameter is greater than the maximum diameter required, replace it with another pipe with the recommended
diameter before proceeding.
Contact your local LP supplier for further information concerning liquid propane installation.
