the plug has been removed. Move the generator control
switch to the run position. As the unit starts to crank the
fuel solenoid will open and you should get a pressure
reading of between 4 to 6 ounces (7 to 11 inches of water
column).
7. If the pressure is correct, remove the meter and
reinstall the pipe plug.
8. You are now ready to make the final fuel mixture
adjustment. Refer to adjustment section in this manual.
PROPANE TO NATURAL GAS
1. Turn off fuel supply.
2. Remove the fuel line from the carburetor at the
demand regulator.
3. Invert the regulator so the column is in the upright
position. Remove the cap on the upright column of the
regulator. This will expose the pressure spring adjusting
screw. Turn the screw all the way out (CCW) and then
back in (CW) about 8 turns. The plug should be approxi-
mately half way down for initial starting.
4. Reconnect the fuel line at the regulator.
5. Remove the 1/8 NPT plug (the one closest to fuel
solenoid) located on what is now the bottom of the
regulator. Connect a fuel pressure meter or a manometer
where the plug has been removed. Move the generator
control switch to the run position. As the unit starts to
crank the fuel solenoid will open and you should get a
pressure reading of between 4 to 6 ounces (7 to 11
inches of water column).
6. If the pressure is correct, remove the meter and
reinstall the pipe plug. Next remove the 1/8 inch NPT
plug on the carburetor side of the regulator and install the
pressure meter. Move the generator switch to the run
position. As soon as the solenoid opens the pressure
should rise 2.5 to 3 oz. just as the engine starts to crank.
If it is within this range replace the cap on the column. If
not, adjust the screw down to increase and up to
decrease and retest.
7. You are now ready to make the final fuel mixture
adjustment. Refer to adjustment section in this manual.
LUBRICATION
Before starting the engine, fill the crankcase with the
proper weight/grade of oil, as recommended by the
engine manufacturer’s maintenance instructions. The
necessity of using the correct oil, and keeping the
crankcase full cannot be over emphasized.
INSTALLING THE BATTERY
**** CAUTION ****
In the following battery installation procedure, check to
be sure the selector switch remains in the “stop” 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 highest CCA
rated battery, within the correct BCI group, will increase
cold weather starting performance. Use only Mainte-
nance Free batteries, this will reduce the need to refill the
battery with water. Gel batteries should not be used with
the battery tender installed in the generator enclosure.

*****CAUTION*****
EQUIPMENT DAMAGE - Always connect the positive
cable first and the negative cable last, when disconnect-
ing it is negative cable first and positive last. Failure to
connect and disconnect in the proper sequence can
cause equipment damage.
Observe polarities: connect the positive (+) battery
terminal to the (+) cable from the control panel; the
negative (-) battery terminal is connected to the negative
cable (ground) from the engine generator assembly.
All connections must be clean and tight. Check the
electrolyte (fluid) in the battery periodically to be sure it is
above the plates. Never allow the battery to remain in a
discharged condition.
*****CAUTION*****
EQUIPMENT DAMAGE - NEVER jump start these units.
Doing so will destroy the engine control module render-
ing the unit non-operational. Remove and fully recharge
the battery before attempting to start.
CONNECTING THE BATTERY CHARGER &
BLOCKHEATER
A two-stage battery tender is provided on all PSS series
generators. This battery tender charges at a rate of 750
mA until the battery is fully charged and then automati-
cally switches to a 13.2 VDC float charger. The charger
has an indicator light on it, red indicates it is charging,
and green indicates it is in the storage mode (float
charge). This charger is mounted on the engine genera-
tor set in the same location as the other AC and DC
connections.
This battery tender requires a circuit breaker protected
AC circuit from your distribution panel be run out to the
engine generator set. These AC wires can be run in the
same conduit as the other AC leads from the generator.
It is suggest that this circuit be fused for 15 amps, then
both the battery charger and the block heater can be
connected to the same circuit. The block heater is
optional on the PSS8000 and is installed standard on the
PSS20000. At this time there is no block heater available
for the PSS12000.
The PSS8000 and PSS12000 have a 120 volt recep-
tacle mounted in the generator connection box. The
receptacle is prewired with black, white and green leads
