Fuel Conversion, 14RES/RESL
Two fuel connections on the fuel block allow field-
conversion between natural gas and LP vapor. The fuel
metering valves are factory-set and sealed to comply
with applicable emission standards and to provide the
best possible hot and cold starting.
Note: Do not adjust the factory-sealed fuel-metering
adjustments on the fuel block. Changing the fuel-
metering adjustments may violate federal or state
laws.
Use the following procedure to convert from natural gas
(NG) to LP vapor. The procedure includes moving the
fuel connection from the natural gas to the LP port,
plugging the natural gas port, and disconnecting the
leads for the digital spark advance ignition (DSAI). See
Figure 1-11 or Figure 1-12 for the fuel system
component locations.
Procedure to convert from NG to LP, 14RES/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 in the fuel block. See Figure 1-13.
6. Remove the hose fitting from the natural gas outlet
port in the fuel block. See Figure 1-13.
7. Remove the plug from the LP port in the fuel block.
See Figure 1-13.
8. Clean the plug with a dry cloth or brush, apply fresh
pipe sealant, and install the plug into the natural
gas outlet port.
9. Clean the hose fitting with a dry cloth or brush,
apply fresh pipe sealant to the threads, and install
the fitting into the LP port.
Note: Do not adjust the fuel metering valves.
10. Slide the hose onto the hose fitting and secure it
with the clamp.
11. Disconnect the DSAI leads for LP. The DSAI leads
are located near the fuel solenoid valve. See
Figure 1-11 or Figure 1-12.
12. Connect and turn on the new fuel supply.
