Converting the Fuel System Type
The generator set leaves the factory set up for natural gas. For operation on liquid
propane vapor, the generator set must be converted by configuring the generator
set control for propane and manually changing the fuel valve position from natural
gas to propane.
1. To change the generator set control's fuel type from natural gas to liquid
propane vapor:
a. From the Main screen, select Menu.
b. Press and hold the Next key on the Menu screen for at least 5 seconds to
view the Config Menu.
c. Use the arrow keys to highlight "Config" and click the Enter key. The
Generator Config screen appears.
d. Use the Next key to navigate to the Fuel Type field. Use the arrow keys to
select the fuel type: NG (natural gas; default) or LP (liquid propane).
NOTICE
Do not change the number in the Config field.
NOTICE
The Rating field is not configurable by the user. Instead, it will be
automatically populated based on the Config and Fuel Type field
selections.
e. Keep selecting the Back button to save the settings and return to the Main
screen.
