How Do You Operate Electric And Gas Water Heater Temperature Controls?
Gas Controls Gas water heaters have a thermostat inside the water of the tank, which is then connected to the front control at the bottom of the water heater. On the front control there is a dial with three settings: ON, OFF and PILOT. Above the dial is a knob with a recessed screw which controls the gas flame. Below the bottom of the dial are three tubes. The largest tube, always in the middle, is the natural gas supply tube. The medium-sized tube, usually the one on the right, feeds natural gas to the pilot light switch. The smallest tube, usually the one on the left, is called the thermocouple. The thermocouple allows you to control the amount of gas fed to the pilot after it has been lit, therefore controlling the size of the flame. Lastly, the burner assembly is attached to the tubes and control; it can be removed for cleaning, but do not take apart the control itself. • If your pilot light will ignite but not remain lit, then the thermocouple needs to be replaced.
