No, that switch turns on the propane side of the water heater. You can use both 110V and propane at the same time for faster hot water recovery. Unless you ordered heating pads for your tanks...you probably dont have them. I'm not sure they were even an option for a 2011 BC.
Thanks for posting this. I needed this answer as well.
If I can ask another couple of questions, I have the Suburban SW10DE water heater. This owner's manual isn't clear to me on a couple of points.
(1) In addition to the rocker switch for propane, I also have a switch next to the tank monitor panel marked "Electric W/H". Does this indicate that, in addition to propane, I have an electric anode that runs off shore power? (I can't imagine it would operate off battery only.) Therefore, with shore power, the rocker switch can stay off, the Electric W/H switch turned on and lights up, and the electrical anode heats the water, correct?
(2) One additional question, if I may. When draining and flushing the Hot Water Tank, you turn both the propane rocker switch AND the Electric W/H switch off, let the water cool, then pull the drain plug. To flush, just fill the tank and drain it a few times. How do you know when the hot water tank is full? When you get a steady stream of water through the hot water outlets in the sinks and shower?
Sorry for the noob questions!
