On a dual-fuel unit, you would likely need to adjust the metering on the secondary regulator, assuming the natural gas was supplied at sufficient pressure.
As an example, a 20KW generator fully-loaded on propane will consume 122 cubic feet of gas an hour. That same generator fueled on natural gas will consume 245 cubic feet of gas an hour. It’s twice the amount of fuel in cubic feet an hour on natural gas than on propane. Plus there is a 15 percent reduction in the power output of the generator on natural gas vs propane.
