Update

I got the new water heater installed.  After a couple of days, the control board failed!  I did some research and found this is not uncommon.  Instead of taking a chance on a warranty covered board, I went ahead and ordered a quality board from Dinosaur Electronics.  The boards from this company have never let me down like the OEM boards.  This water heater runs on both 120 volt electric and/or propane, I don’t miss the tankless heater due to this new heater’s high input.  While doing the gas lines, I went ahead and hooked up my Wave 6 catalytic space heater which uses less gas when I don’t need the furnace.  I’m now better set up for boondocking!
