Example 1
Determine the pipe sizing for a 2 PSI Natural Gas installation.
Because the appliance near junction N is farthest away from the gas meter, use this distance.
Section A-N is 95' long. Use the 100' line on the “Natural Gas @ 2 PSI” chart.
NOTE:
Sections I-K, C-H, and D-F are identical to the section L-N and should also use 1" pipe.
