• First, determine what size pipe is required. Refer to NFPA 54 for NG or NFPA 58 for LP for further information.
• Always refer to the owner’s manual for the proper BTU / megajoule and required gas pressures. To calculate BTU or Megajoules:
– Natural Gas: BTU=Cubic feet / hour x 1000
Megajoules=Cubic meters / hour x 37.26
– Liquid Propane Vapor: BTU=Cubic feet / hour x 2500
Megajoules=Cubic meters / hour x 93.15
• Start by measuring the distance from the generator to the gas source. The generator should be plumbed directly from the source, not off the end
of an existing system.
• When measuring the pipe length, add 2.5ft. (.76m) for every angle or bend in the pipe and add that to the overall pipe distance.
