LP/NG FUEL CONVERSION
The ULPSS2H4W/E generator sets have been
tested on NATURAL GAS prior to shipment. If you
are going to use them on LP vapor, follow the pro-
cedures in FUEL INSTALLATION. See Page 6.
INSTALLING THE BATTERY
**** CAUTION ****
In the following battery installation procedure, check
to be sure the selector switch remains in the “off”
position. This should be your last step before initial
start-up.
A customer supplied twelve-volt battery is required to
complete the installation. Installation of the high-
est CCA rated battery, within the correct BCI group
(size), will increase cold weather starting perfor-
mance. Gel batteries should not be used with the
battery tender installed in the generator enclosure.

Installation and servicing of batteries must be per-
formed or supervised only by personnel knowledge-
able of batteries and the required precautions. Keep
unauthorized personnel away from batteries.
