Most Generac air-cooled units are factory-set for natural gas (NG) and easily field convertible to liquid propane (LP). A fuel conversion knob is located on the mixer body, just behind the air filter. On 10 kW models, the conversion knob will be under the mixer rather than on top and will be turned counterclockwise.
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: 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.
Control panel
The controller will also need to be configured for the appropriate fuel type:
1. Press ENTER to bring up the main menu. 2. Use the arrow keys to navigate to the SUB MENUS selection and press ENTER. 3. Use the arrow keys to navigate to the EDI menu and press ENTER. 4. Use the arrow keys to select the Fuel Selection menu and press ENTER. 4. Use the arrow keys to toggle the appropriate fuel selection and press ENTER.
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.
Incorrect fuel pressure, undersized lines, or improper fuel conversions are not covered under warranty.
Owners should refer to the owner’s/install manual for fuel conversion instructions on the PowerPact and liquid-cooled units.
