* Natural gas is in m
** Propane is in gal/h (LP) / L/h (LP) / ft
*** 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
Megajoules/h = m
– Liquid Propane Gas (Vapor):
BTU/h = ft
Megajoules/h = m

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 appropriately sized and cor-
rectly placed fuel pressure regulator, not
off the end of an existing low pressure sys-
tem.
