Customer Question

I have a RS 12000 home standby generator that was originally natural gas. I want to convert to propane as I now live in a rural area. What do I need? A new regulator? Is there an onan part number to do this that I could order and install myself?

If this is an older version of the unit, an orifice will need to be installed in the fuel elbow. The orifice is part number(###) ###-####

If this is a newer version of the unit, the elbow needs to be replaced with a different elbow that has a smaller opening in it.

After that, the carburetor must be properly adjusted to compensate for the different fuel.
