For LPG 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
LPG, install the LPG orifice as described below. See
Figure 1-13 for the fuel system component locations.
Note: The generator set harness may contain a pair of
DSAI leads near the fuel solenoid valve.
Connecting or disconnecting these leads has no
effect on the 20RESA/RESAL operation.
