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
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.

1.12 RECONFIGURING THE FUEL
SYSTEM
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.
