LIFTING THE GENERATOR


When lifting or hoisting equipment is used, be
careful not to touch overhead power lines. The
generators weight of more than 900 pounds
requires proper tools, equipment, and qualified
personnel to be used in all phases of handling
and unpacking.

m 3 /hr 1.7
ft 3 /hr 60.7
Fuel consumption is given at rated maximum
continuous power output when using natural gas
rated at 1000 Btu per cubic foot. LP gas is rated at
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 vapor,
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).
