PLACEMENT: SAFE DISTANCES

The National Electrical Code requires minimum distances of ten feet from the propane tanks and five feet from any building wall.

5.3 LP FUEL CONSUMPTION

NOTE: The required fuel pressure for LP Vapor is 10-12” water column (19-22mm mercury).

These are approximate values, use the appropriate spec sheet or owner’s manual for specific values.

Verify that gas meter is capable of providing enough fuel fl ow to include household appliances and all other loads.

Gaseous fuels such as natural gas and liquid propane (LP) gas are highly explosive. Even the slightest spark can ignite such fuels and cause an explosion. No leakage of fuel is permitted. Natural gas, which is lighter than air, tends to collect in high areas. LP gas is heavier than air and tends to settle in low areas.

NOTE: A minimum of one approved full flow manual shut-off valve must be installed in the gaseous fuel supply line. The valve must be easily accessible. Local codes determine the proper location.

5.4 FUEL LINE SIZING

• 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 for 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.
