6.12.3 Fuel Conversio n, 20 kW Models
For LPG 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 LPG vapor, install the orifice as described below. See
Figure 6-26 for the fuel system component locations.
For controllers with firmware version 4.5 or higher, use
SiteTech software to change the fuel type setting in the
Genset System group. The fuel type setting is important
if a Load Control Module (LCM) or load shed kit is
connected to the generator controller.
Note: The generator set harness may contain a pair of
leads labelled 65 and N near the fuel solenoid
valve. These leads are used on the
14RESA/RESAL generator sets. Connecting or
disconnecting these leads has no effect on the
operation of 2 0 kW generator sets.
