These engine/generator sets are very easy to convert between
LP or NG. As the engine timing is controlled by the ECU on the
engine you only need to tell it what fuel you want to operate on.
In the customer connection box there is a fuel selection terminal.
A small rocker switch has been provide on the underside of the
engine control cabinet (see ref L on Page 9) for this purpose.
Opening the rocker switch will tell the ECU mounted on the
engine that you are operating on NG Fuel. Closing the rocker
switch will tell the ECU that the fuel being supplied is LP. The
ECU will then reprogram the engine to operate on the proper fuel.
