Fuel Conversion, 20RES/RESL
For LP vapor fuel, an orifice is used in the fuel line. The
unit is typically shipped set up for natural gas, with the
loose orifice tied near the fuel solenoid valve. To convert
to LP vapor, install the orifice and disconnect the spark
advance leads as described below. See Figure 1-15 for
the fuel system component locations.
Procedure to Convert from NG to LP, 20RES/RESL
1. Press the OFF button on the generator set
controller and remove the F3 fuse (located in the
service access area).
2. Disconnect the power to the battery charger.
3. Disconnect the generator set engine starting
battery, negative (--) lead first.
4. Turn off the fuel supply.
5. Remove the hose clamp and fuel hose from the
hose fitting. See Figure 1-15.
6. Insert the orifice into the hose fitting.
Figure 1-15.
7. Slide the hose onto the hose fitting and secure it
with the clamp.
8. Disconnect digital spark-advance module (DSAI)
leads 65 and N5 for LP. The DSAI leads are located
