INSTALLATION

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.

6.Repeat process until engine starts.

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

8.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.

FUEL SYSTEM SELECTION

The engine of your Home Standby Generator 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.Set AUTO/OFF/MANUAL switch to OFF.

3.Pull service disconnect from disconnect box.

4.Remove 15 Amp fuse.

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

6.Reinstall 15 Amp fuse.

7.Reinstall service disconnect in disconnect box.

8.Set AUTO/OFF/MANUAL switch to AUTO.

9.Reset exercise timer following instructions in Setting Exercise Timer.

The generator 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.

INITIAL START-UP (NO LOAD)

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

1.Set AUTO/OFF/MANUAL switch to OFF.

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

3.Install 15 Amp fuse in control panel.

4.Set AUTO/OFF/MANUAL switch to MANUAL.

NOTE: When the Home Standby Generator 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.

5.DO NOT crank engine for more than 15 seconds, then pause for 15 seconds to reduce heat in starter.

9.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.

10.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.

11.Set AUTO/OFF/MANUAL switch to OFF. Engine will shut down.

AUTOMATIC OPERATION

SEQUENCE

The generator’s control panel houses a logic control circuit board. This control board constantly monitors utility power source voltage. Should that voltage drop below a preset level, control board action will signal the engine to crank and start.

When utility source voltage is restored above a preset voltage level, the engine is signaled to shut down.

The actual system operation is not adjustable and is sequenced by sensors and timers on the control board, as follows:

Utility Voltage Dropout Sensor

•This sensor monitors utility source voltage.

•If utility source voltage drops below 70 percent of the nominal supply voltage, the sensor energizes a six second timer.

•Once the timer has expired, the generator will start.

Utility Voltage Pickup Sensor

This sensor monitors utility power supply voltage. When that voltage is restored above 80 percent of the nominal source voltage, a time delay starts timing and the generator will go to engine cool-down.
