INSTALLATION

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.

CAUTION

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 (indicated by POSITIVE, POS, or (+)).

6.Connect negative battery cable to negative battery terminal (indicated by NEGATIVE, NEG, or (-).

7.Ensure hardware on both positive and negative battery terminals is secure.

8.Reinstall 15 Amp fuse in control panel.

9.Set generator's system switch to AUTO.

10.Close “Control Panel” access door.

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.
