You have a Suburban Water Heater
Inside On/Off Switch with Light is for the propane side....need propane valved in service AND 12VDC Power
IF it is a combo unit...electric & propane----the Electric On/Off Switch is in the Outside Compartment. Lower Left corner behind/below gas valve
Need 120VAC Power for the electric to work. **No DC needed for AC side
(The 110 15A is just enough for element provided other AC demands are off----1440W element/13A when energized)
Above the gas valve is a Cover with Push to Reset buttons.
Behind cover are the Sets of T-stats for electric & propane
High Temp T-stat is a manual reset if it trips (180*F)....if tripped you will feel resistance when pushing in on buttons
Left side is the 120VAC Set (electric)
Right side is the 12VDC set (propane)
A Rockwood always has a 2nd switch for electric operation inside on the switch panel. Both the one on the inside switch panel and the one on the heater itself accessed from the exterior door mentioned above have to be on for 120 VAC operation. Most people just leave the outside one on all the time, and use the inside switch which is the reason for having two, so you don't need to go outside to turn the heater on when you want AC operation.
