Started an 8kw today and it runs rough (surges up and down)

voltage and hertz fluctuates

changed unit from nat gas to lp

plumber has lp set 12"

is there something to change in the controller menu for lp?

8 kw

If it is a new unit you need a code from Generac to set the controller.

It could possibly be an issue with the voltage regulator.
