Fuel Conversion; Fuel Consumption - GE HOME GENERATOR SYSTEM 11000 WATT Installation And 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. The LP Conversion Kit
(supplied) is required to convert the unit to LP vapor fuel.
LP fuel inlet pressure must be between 11 and 14 inches
water column at full load with all gas appliances turned on
and operating.

Estimated fuel supply requirements at half and full load for
natural gas and LP vapor fuels are shown here.

To configure the fuel system for LP use:
1. Set generator's system switch to OFF.
2. Remove 15 Amp fuse from control panel.
3. Remove roof, divider, side panels, exhaust panel and
muffler cover.
4. Change main jet in fuel mixer following instructions
provided in LP Conversion Kit.
5. Reinstall muffler cover, exhaust panel, side panels,
divider and roof.
6. Reinstall 15 Amp fuse in control panel.
7. Set generator's system switch to AUTO.
The system is now ready to operate automatically using
LP vapor fuel.
