‹1.9.1 7 KW, 410CC ENGINE

To reconfigure the fuel system from NG to LP, follow these steps (Figure 1.4):

NOTE:

The primary regulator for the propane supply is NOT INCLUDED with the generator. A fuel pres- sure of 10 to 12 inches of water column (0.36 to

0.43psi) to the fuel inlet of the generator MUST BE SUPPLIED.

1.Turn off the main gas supply (if connected).

2.Open the roof and remove the door.

3.Remove the battery (if installed).

4.Disconnect wire #0 and wire #14 from the gas solenoid on top of the demand regulator.

5.Remove the carburetor fuel hose from the outlet port of the demand regulator.

6.Remove the demand regulator by removing the fastener that retains the regulator mounting bracket.

7.Remove the square headed steel pipe plug from outlet port #1 and the brass hose barb fitting from outlet port #2.

8.Refit the brass hose barb fitting to outlet port #1 and the square headed steel pipe plug to outlet port #2.
