1.11 FUEL CONSUMPTION

15 kW Models

Using Natural Gas	........................................277 cu. ft. per hour
Using LP Gas	110 cubic ft.(3.1 gal.) 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 and 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.

1.12RECONFIGURING THE FUEL SYSTEM

NOTE:

All models are configured for natural gas from the factory.

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

1.Turn the main gas supply off.

2.Remove the carburetor fuel hose from the outlet port (Port 1) of the demand regulator (Figure 1.8).

3.Remove the brass hose fitting from the outlet port (Port 1) of the demand regulator.

4.Remove pipe plug from Port 2.

5.Install brass hose fitting into Port 2.

6.Install pipe plug into Port 1.

7.Connect carburetor gas hose to brass fitting.

8.Tighten all clamps and plugs.

9.Make sure fuel supply is of the proper pressure and type for configuration.

10.Reverse the procedure to convert back to natural gas.
