Suburban Nautilus On Demand RV Water Heater (IW60), Model 5286A Includes on-demand water heater, on demand water heater replacement panel for Suburban 6 gallon tank water heater and 2 exhaust vent caps (2” and 3”) as seen in pictures. I bought this on demand water heater right before the pandemic became a pandemic then it sat for over two years before I got around to installing. Come to find out the original water heater wiring shares a DC circuit with some of the lights in the camper and would pop the fuses if too many lights were on. Adding separate circuit was not an option, so I put the original water heater back in the same day and selling this one.
