Fuel Consumption
Fuel Line Sizing
Selecting the correct size fuel line is crucial to correct
operation of the unit.
IMPORTANT NOTE: Generator inlet size DOES NOT
dictate size of gas pipe to be used!
For further information, see NFPA 54 for NG, or NFPA 58
or ICC IFGC for LP.
Measure distance from generator to fuel source on a low
pressure gas system.
IMPORTANT NOTE: Generator should be plumbed
directly from the fuel source through an appropri-
ately sized and correctly placed fuel pressure regula-
tor, not off the end of an existing low pressure
system.

*** Values given are approximate
These are approximate values. Use the appropriate spec sheet or fuel data decal for specific values.
Verify gas meter is capable of providing enough fuel flow to include household appliances and all other loads.
NOTE: The fuel supply and pipe MUST be sized at 100% load BTU/h (Megajoule/h) rating.
Always see fuel data decal for the correct BTU/h or Megajoule/h, and required fuel pressures:
– Natural Gas:
BTU/h = ft

/h x 1000
Megajoules/h = m

/h x 37.26
– Liquid Propane Gas (Vapor):
