The attached is the only control I see. That is, on/off switch.
Will the water heater turn off automatically when the water gets hot enough ? I'm just afraid that the gas/fire will just turn on indefinitely and burn the tank
Pawntan, you have a Suburban water heater, and the control you have in the pic is to turn on/off the DSI (direct spark ignitor) for the propane.
Suburban water heaters have a non-adjustable thermostat that is preset for a certain temperature. if you want to change the temperature, you have to replace the entire hi-limit ECO thermostat. I believe Suburban makes three different temp thermostats. When the water reaches the temp, then the thermostat cuts power so the propane does not continue to burn.
Also, you may possibly have a water heater that also has an electric heating element as another possible source of heating (but you will have to check to see). If so then you have a second switch which is on the face of the water heater, to turn this electric heating element on. However, even with a second heating source, the thermostats still control the temperatures, and won't make the water hotter.
This FAQ may help explain it ALL better...and let you see if you have an electric heating element too.
Suburban's electric switch and much more
