Fuel Conversion - Briggs & Stratton Home Generator System Installation & Start-Up Manual

Fuel Conversion

The engine of your home generator system is factory
calibrated to run on natural gas (NG). It may also be
operated on liquefied petroleum (LP) vapor. There is no
additional hardware/equipment required to switch between
either fuel. However, LP fuel inlet pressure must be between
11 and 14 inches water column.
To configure the 12kW home generator fuel system for
LP use:
1. Open control panel and oil fill access doors.
2. Set generator's system switch to OFF.
3. Remove 15 Amp fuse from control panel.
4. Connect the fuel select solenoid by joining the two-pin
electrical connector (C).

5. Reinstall 15 Amp fuse in control panel.
6. Set generator's system switch to AUTO.
7. Close control panel and oil fill access doors.
The system is now ready to operate automatically using
LP fuel. With a fixed main jet for LP gas, there is no need to
perform any engine adjustments for LP operation.
To configure the 15kW home generator fuel system for
LP use:

5. Remove fuel line from NG inlet.
6. Place cap from LP inlet onto NG inlet.
7. From oil fill access area, pull fuel line (D) out of top
hole and route it through bottom hole.
Failure to route fuel line through bottom hole may cause the
fuel line to kink. When tightening fuel hose fittings make
certain the fuel hose does not twist or kink. If the fuel line
kinks, the generator may start but will not operate properly.
8. Connect fuel line (D) to T-valve's LP inlet.
9. Reinstall 15 Amp fuse in control panel.
10. Set generator's system switch to AUTO.
11. Close control panel and oil fill access doors.
The system is now ready to operate automatically using
LP fuel. With a fixed main jet for LP gas, there is no need to
perform any engine adjustments for LP operation.
