When the generator is started for the very first time, it will
require that air in the gaseous fuel lines be purged. This may
cause the engine to run roughly for a few minutes.

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
