Section 1 — General Information
*Rated power of generator is subject to and limited by such factors as ambient temperature, altitude, engine condition, and other factors. Engine power will decrease about 2.5% for each 1000 feet above 500 feet and will decrease an addition- al 2.5% for each 10°F above 104°F. Maximum output power of the generator is limited by maximum engine power.

FUEL INLET
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.
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.
1.12RECONFIGURING THE FUEL SYSTEM FOR LP VAPOR
NOTE:
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).
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.Move dip switch position 4 on the control board to the off position (LP vapor, see Figure 3.2 and Section 3.8).
11.Reverse the procedure to convert back to natural gas.

NOTE:
Port 1 is for NG only and Port 2 is for LP vapor only. No provision for dual fuel has been made.
DANGER
Serious injury or damage may occur if not con-
!figured properly. Please consult a dealer with any questions.
1.13 ENGINE OIL RECOMMENDATIONS
The unit has been filled with
| Temperature | Oil Grade (Recommended) |
|
| Above 80° F (27° C) | SAE 30W or |
|
| 32° to 80° F | SAE |
|
| Below 32° F (0° C) | SAE 10W or |
|
NOTE:
Synthetic oil is highly recommended when the generator will be operating in ambient tempera- tures which regularly exceed 90° F and/or fall below 30° F.
Any attempt to crank or start the engine before
!it has been properly serviced with the recom- mended oil may result in an engine failure.
