1.12 FUEL CONSUMPTION

15 kW Models

Using Natural Gas	........................................236 cu. ft. per hour
Using LP Gas	92 cu. ft. per hour
20 kW Models
Using Natural Gas	........................................307 cu. ft. per hour
Using LP Gas	122 cu. ft. per hour
25 kW Models
Using Natural Gas	........................................441 cu. ft. per hour
Using LP Gas	175 cu. ft. per hour
	NOTE:

Fuel consumption is given at rated maximum con- tinuous power output when using natural gas rated at 1000 Btu per cubic foot; or LP gas rated 2520 Btu per cubic foot. Actual fuel consumption obtained may vary depending on such variables as applied load, ambient temperature, engine condi- tions and other environmental factors.

Fuel pressure for a natural gas set up should be five inches to 14 inches of water column (0.18 to 0.5 psi) at all load ranges.

Fuel pressure for an LP vapor set up should be 11 inches to 14 inches of water column (0.4 to 0.5 psi) at all load ranges.

1.13RECONFIGURING THE FUEL SYSTEM FOR LP VAPOR

NOTE:

All models are configured for natural gas (NG) from the factory.

To reconfigure the fuel system from NG to LP vapor, follow these steps:

1. Turn the main gas supply off.

*Rated power of generator is subject to and limited by such factors as ambient temperature, altitude, engine condition, and other fac- tors. Engine power will decrease about 3.5% for each 1000 feet above sea level and will decrease an additional 1% for each 10°F above 60°F. Maximum output power of the generator is limited by maximum engine power.
