See the Installation Manual for important recom-
mendations regarding the installation of an LPG va-
por withdrawal type of fuel supply system. Gensets
equipped for vapor withdrawal of LPG must be
equipped with a fuel shutoff solenoid valve and de-
mand regulator. These are available as a kit for
mounting near the genset. See Figure 6-29.
