Reconfiguring The Fuel System - Eaton Generator Owner's Manual

General Information


Gaseous fuels such as natural gas and liquid
propane (LP) gas are highly explosive. Even
the slightest spark can ignite such fuels and
cause an explosion. No leakage of fuel is
permitted. Natural gas, which is lighter than
air, tends to collect in high areas. LP gas is
heavier than air and tends to settle in low
areas.
A minimum of one approved manual shut-off valve must be
installed in the gaseous fuel supply line. The valve must be eas-
ily accessible. Local codes determine the proper location.

RECONFIGURING THE FUEL SYSTEM

1.10.1 8 KW, 410CC ENGINE
To reconfigure the fuel system from NG to LP , follow these steps
(Figure 1.4):
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) to the fuel inlet of the generator MUST
BE SUPPLIED.
1. Turn off the main gas supply (if connected).
2. Open the roof and remove the door.
3. Remove the battery (if installed).
4. Take the plastic T-handle fuel selector in the poly bag supplied
with the generator.
5. Locate the selector knob on the air box cover, behind the
yellow air filter door and power bulge. The unit comes from
the factory in the NG (Natural Gas) position. Grasping the
T-handle, insert the pin end into the hole in the selector knob
and pull out to overcome spring pressure and then twist
clockwise 90 degrees and allow the selector to return in once
aligned with the LP (Liquid Propane) position.
6. Save this tool with the Owner's Manual.
7. Install the battery, door and close the roof.
8. Reverse the procedure to convert back to natural gas.
