2.1.2 Fuel Pipe Size
Ensure that the fuel pipe size and length meet the specifications in Figure 10. Measure the pipe length from the primary gas
pressure regulator to the pipe connection on the generator set fuel inlet. Add 2.4 m (8 ft.) to the measured length for each
90-degree elbow. Compare the total pipe length with the chart in Figure 10 to find the required pipe size.
Contact the local LPG provider for LPG installation information.
