WARNING
Storage batteries give off explosive hydrogen gas
during recharging.
Slightest spark will ignite hydrogen and cause
explosion.
Battery electrolyte fluid contains acid and is
extremely caustic.
Contact with battery contents will cause severe
chemical burns.
A battery presents a risk of electrical shock and
high short circuit current.
• DO NOT dispose of battery in a fire.
• DO NOT allow any open flame, spark, heat, or lit cigarette
during and for several minutes after charging a battery.
• DO NOT open or mutilate the battery.
• Wear protective goggles, rubber apron, and rubber gloves.
• Remove watches, rings, or other metal objects.
• Use tools with insulated handles.
NOTE: With the battery installed and utility power available to
the Automatic Transfer Switch, the battery receives a trickle
charge whenever the engine is not running. This process may
take up to 72 hours to fully charge a battery from 5 Volts.
The trickle charge cannot be used to recharge a battery that
is completely discharged.
5. Connect negative battery cable to negative battery terminal
(indicated by NEGATIVE, NEG, or (-)).
6. Ensure hardware on both positive and negative battery
terminals is secure.
7. Reinstall 15 Amp fuse in control panel.
Installing the 15A fuse could cause the engine to
start.
• DO NOT install this fuse until all plumbing and wiring has been
completed and inspected.
8. Set generator's system switch to AUTO.
Servicing the Battery
If it is necessary to service the battery, proceed as follows:
1. Open "Control Panel" access door.
2. Set generator's system switch to OFF.
3. Remove 15 Amp fuse from control panel.
4. Service or replace battery as required.
5. Connect red battery cable to battery positive terminal

Fuel Supply System

Ensure that all fuel pipe connections are tight, secure and
without leaks.
Ensure that all gas line shutoff valves are OPEN and that
adequate fuel pressure is available whenever automatic
operation is desired.

FUEL SYSTEM SELECTION

The engine of your Home Generator System is factory
calibrated to run on natural gas (NG). It may also be operated
on liquefied petroleum (LP) vapor. There is no additional
hardware/equipment required to switch between either fuel.
However, LP fuel inlet pressure must be between 11 and
14 inches water column.
To configure the fuel system for LP use:
1. Open control panel and oil fill access doors.
2. Set generator's system switch to OFF.
3. Remove 15 Amp fuse from control panel.
For a 12kW Home Generator System:
4. Connect the fuel select solenoid by joining the two-pin
electrical connector shown in Figure 12.
Figure 12 — Fuel Select Solenoid Connection
Push two
connectors together
5. Reinstall 15 Amp fuse in control panel.
6. Set generator's system switch to AUTO.
7. Close control panel and oil fill access doors.
The system is now ready to operate automatically using LP
fuel. With a fixed main jet for LP gas, there is no need to
perform any engine adjustments for LP operation.
