1.7 FUEL REQUIREMENTS
AND RECOMMENDATIONS
With LP gas, use only the vapor withdrawal sys-
tem. This type of system uses the vapors formed
above the liquid fuel in the storage tank.
The engine has been fitted with a fuel carburetion
system that meets the specifications of the 1997
California Air Resources Board for tamper-proof
dual fuel systems. The unit will run on natural gas or
LP gas, but it has been factory set to run on natural
gas. Should the primary fuel need to be changed to
LP gas, the fuel system needs to be reconfigured. See
instructions in the “Reconfiguring the Fuel System”
section.
Recommended fuels should have a Btu content of at
least 1,000 Btus per cubic foot for natural gas; or at
least 2,520 Btus per cubic foot for LP gas. Ask the
fuel supplier for the Btu content of the fuel.
Required fuel pressure for natural gas is 5 inches
to 7 inches water column (0.18 to 0.25 psi); and
for liquid propane, 11 inches to 14 inches of water
column (0.4 to 0.5 psi).
NOTE:
Any piping used to connect the generator to the
fuel supply should be of adequate size to ensure
the fuel pressure NEVER drops below 4 inches
water column for natural gas or 10 inches water
column for liquid propane for all load ranges.
1.8 FUEL CONSUMPTION
* Natural gas is in cubic feet per hour.
** LP is in gallons per hour/cubic feet per hour.
*** Values given are approximate.
DANGER
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.
