RECONFIGURING THE FUEL SYSTEM

To reconfigure the fuel system from NG to LP , follow these steps:
The primary regulator for the propane supply is NOT INCLUDED
with the generator. A fuel pressure of 10 to 12 inches of water
column (0.36 to 0.43 psi) MUST BE SUPPLIED to the fuel inlet
of the generator.
1. Open the roof.
2. For 10kW units: Loosen clamp and slide back the air inlet
hose.
• Slide fuel selector on carburetor out towards the back of the
enclosure (Figures 1.3 and 1.4).
• Return the inlet hose and tighten clamp securely.
For 12, 15 and 20kW units: remove the air cleaner cover.
• Slide the selector lever out towards the back of the enclosure
(Figures 1.5 and 1.6).
• Return the air cleaner cover and tighten the two thumb
screws.
3. Close the roof.
4. Reverse the procedure to convert back to natural gas.

HIGH ALTITUDE OPERATION

The fuel system on this generator may be influenced by operation
at higher altitudes. Proper operation can be ensured by installing
an altitude kit when required. See the table below to determine
when an altitude kit is required. Operating this generator without
the proper altitude kit installed may increase the engine's emis-
sions and decrease fuel economy and performance. Kits may be
obtained from any Dealer, and should be installed by a qualified
individual.
