Fuel System Selection

INSTALLATION

The engine of your Home Generator System is factory calibrated to run on natural gas (NG). It may also be operated on liquid propane vapor (LP).

To configure the fuel system for LP use:

1.LP fuel inlet pressure must be between 11 and 14 inches water column.

2.Pull service disconnect from disconnect box.

3.Remove 15 Amp fuse from control panel.

4.Change main jet in fuel mixer following instruction sheet provided in LP conversion kit.

5.Reinstall 15 Amp fuse in control panel.

6.Reinstall service disconnect in disconnect box.

The generator is now ready to operate using LP fuel.With a fixed main jet for LP gas, there is no need to perform any engine adjustments for LP operation.

INITIAL START-UP (NO LOAD)

Begin testing the generator without any electrical loads connected, as follows:

1.Set generator’s main circuit breaker to OFF (open) position.

2.Install 15 Amp fuse in control panel.

3.Push and hold START/RUN/STOP switch in START position until LED comes on.

IMPORTANT: If you release the switch from the START position before LED comes on, the generator will shut down.

NOTE: DO NOT crank engine for more than 15 seconds, then pause for 15 seconds to reduce heat in starter. Repeat process until engine starts.

NOTE: When the Home Generator System is started for the very first time, it will require that air in the gaseous fuel lines be purged.This may take a few minutes.

4.Listen for unusual noises, vibration or other indications of abnormal operation. Check for oil leaks while the engine runs.

5.Let engine warm up for about five minutes to allow internal temperatures to stabilize.Then, set generators main circuit breaker to ON (or closed) position.

6.Connect an RMS AC voltmeter and a frequency meter to check generator output at load side of circuit breaker.Voltage should be 230-240 Volts, frequency should be 62.0 - 62.5 Hz.

7.Check generator output between one generator connection lug and neutral lug, then between other generator connection lug and neutral lug. In both cases, voltage reading should be between 115-120 Volts.

8.Push and hold START/RUN/STOP switch in STOP position until LED turns off. Engine will shut down.

INSTALLATION

INSPECTION

Before placing the Home Generator System into service, inspect the entire installation carefully. Ensure that any scratches or broken paint on the inside or outside of the enclosure are touched up with the supplied paint.

Complete the ”Installation Checklist” as you make the inspection. Ensure all items have been filled-in and all signatures have been obtained. Instruct the owner to mail the white copy to:
