I have a Mor-flo DSI-6 water heater that won't shut down when the water reaches temperature. I have changed the limit switch and the thermostat, but the pressure relief valve kicks open and the heater stays lit. Does anyone have any suggestions, and where could I get an owner's manual for this unit?
The MH is a 1988 Corsair by General Coach. My next inclination is to change out the pressure relief valve.
