Fuel Consumption
Fuel Line Sizing
Selecting the correct size fuel line is crucial to the proper
operation of the unit.
IMPORTANT NOTE: The generator inlet size does not
dictate the size of gas pipe to be used!
For further information refer to NFPA 54 for NG, or NFPA
58 or ICC IFGC for LP.
Measure the distance from the generator to the gas
source.
IMPORTANT NOTE: The generator should be
plumbed directly from the source, not off the end of
an existing low pressure system.

*** Values given are approximate
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 flow to include household appliances and all other loads.
NOTE: The gas supply and pipe MUST be sized at 100% load BTU / Megajoule rating.
Always refer to the Fuel Data Decal on the generator set for the proper BTU, Megajoule and required gas pressures:
– Natural Gas:
BTU = ft

/h x 1000
Megajoules = m
