Howdy CaptainJohn, do you have the Suburban brand water heater? If so, this may help:
Suburban's electric switch and much more
Also do, you just have one switch on the panel or is there an electric and propane switch?
The circuit breaker only controls the 120 volt AC electric side of a water heater, as explained in the link above
