The water heater is equipped with an adjustable ther-
mostat that automatically controls water temperature.
The indicator lamp remains lit only when the water is
being heated.
The temperature is adjusted by turning the knob coun-
terclockwise (to the left) to increase the temperature
and clockwise (to the right) to decrease the temperature.
The water heater thermostat can be set to guard against
freezing. This position keeps the internal temperature
above the freezing point.
