For Next Generation series generators, fuel conversions must be configured in the Field Pro app during initial setup prior to the first startup using the guided setup process, or in the generator configuration settings. If you need assistance with a fuel conversion, contact a Generac authorized service dealer.
To convert to LP, press and turn the fuel knob 180° clockwise. The knob should then point to the front of the enclosure. On 10 kW models, the conversion knob will be under the mixer rather than on top and will be turned counterclockwise.
Note: On older generators, the knob can get stuck in place. If this happens, gently tap on it with a rubber mallet or similar tool to loosen and turn. Use caution and do not force the knob.
Note: If the orange lever in the image shown below is not present, then the generator likely does not have this fuel conversion capability, and fuel jets will need to be swapped out.
The control panel will also need to be configured for the appropriate fuel type:
Press ENTER to bring up the main menu.
Use the arrow keys to navigate to the SUB MENUS selection and press ENTER.
Use the arrow keys to navigate to the EDIT menu and press ENTER.
Use the arrow keys to select the Fuel Selection menu and press ENTER.
Use the arrow keys to toggle the appropriate fuel selection and press ENTER.
Can my home standby generator run on gasoline?
No. Our home standby generators are only designed to run on natural gas and liquid propane fuel sources. Any modification or improper changes to the fuel system will compromise warranty: What will compromise the home standby generator warranty?
Generac home standby generators are not compatible with dual fuel carb kits.
Additional Information
If NG pressure is too low, and the gas company cannot provide the necessary pressure, the owner will need to consider switching to LP fuel.
