Thermostat Valve Opening Temperature
1. Push down the thermostat valve and insert a string between the
valve and the valve seat.
2. Place the thermostat and a thermostat in a container with water
and gradually heat the water.
3. Hold the string to suspend the thermostat in the water. When the
water temperature rises, the thermostat valve will open, allowing
it to fall down from the string.
Read the temperature at this moment on the thermometer.
4. Continue heating the water and read the temperature when the
valve has risen by about 8 mm (0.3 in.).
5. If the measurement is not acceptable, replace the thermostat.
