Now, the previous owner told me this was to enable the furnace to run. I guess he was wrong, there. I found this out tonight as I was turning everything off for the day, when I heard the water heater gas fire just before flipping the switch labeled "heater" and I heard the gas fire immediately stop.

Hmmm, let's try the furnace with this switch in the off position to prove it's for the furnace. Flipped the furnace thermostat to on and it fired right off.

I think the water heater with no water would fire and quickly get to a temp shut off point and repeat. Not sure how this would damage the tank. Any informed ideas if I may have damage? I guess I'll find out when we get to Florida.

Also, I noticed that the anode rod looks quite different than the one in my trailer's heater. I can only see what looks like a nylon nut that threads into the tank. Should I take this out and inspect asap?
That's pretty funny. The PO must have wondered why on earth the coach went through so much propane! You probably didn't hurt anything by having the heater run propane through an empty tank. Just look for any drips when you re-pressurize the system.

If you have an Atwood water heater, they don't use rods because the tank is made of aluminum. It certainly wouldn't hurt anything to add one. I never have. If it is a Suburban brand, get a rod in there right away.

On an Atwood heater the nylon/plastic plug is part of the safety features and should not be replaced with an anode rod!

Ok, I think I'm squared away on this one.

I guess I have an Atwood. I'll post in a few weeks when I return and let you all know how it went.

Now, if Disney has wifi at our RV slot, I guess I'll post from there...

Thanks for all the help!
