Initial Start-up (No Load)

The unit has been set-up for NG operation at the factory. Fuel conversion, if needed, must be completed prior to performing these steps. See Fuel Conversion.

Before operating the home generator or placing it into service, inspect the entire installation carefully. Then begin testing the system without any electrical loads connected, as follows:

1.Remove three screws (A) that secure control box cover to enclosure to expose unit’s circuit breaker.

2.Connect an accurate frequency meter to line side of generator’s main circuit breaker.

3.Set generator’s main circuit breaker to ON (closed) position.

4.Install 15 Amp fuse in control board.

5.Press and hold MANUAL button on control board for 3 seconds. Engine will start.

When the 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.

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

7.Let engine warm up for about 5 minutes to allow internal temperatures to stabilize.

8.Check generator output at load side of circuit breaker. Voltage should be 225 - 250 Volts, frequency should be 59.0 - 61.0 Hz.

9.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 112 and 125 Volts.

10.Push and hold OFF BUTTON on control board until engine stops.

11.Reinstall control box cover.
