Fuel Conversion, 20RESA/RESAL

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.

Model 20RESA/RESAL generators are equipped with
fuel regulator vent hoses. Drill or punch two holes in the
enclosure at the locations shown on the template in
Appendix B. It may be convenient to cut openings for the
electrical leads at the same time as shown on the
template and in Section 1.9.2.
Insert the open ends of the hoses through the holes to
the outside of the enclosure as shown in Figure 1-14.
