Howdy Rocinate. If you have the dual powered Suburban water heater (electric and gas), then this link may help you understand how each side works independent of each other, as well as how you turn each side on/off.
I'm purely guessing, but from the way you are describing, I think you are only switching one side (either gas or electric) on/off and leaving the other side on all the time................since with the dual powered water heaters, both sides can be turned on at the same time.
