Electric Thermostat 
Adjustment
ELECTRIC THERMOSTAT ADJUSTMENT
On electric water boilers, thermostats are set at the factory to cut off at 200ºF. We do not recommend chang-
ing this. If necessary, adjustment is as follows:
1.  Rotate the thermostat knob to the right to the BOIL position. Pull off the knob. 
2.  Locate the tiny adjustment screw, inside the stem (see figure 1). Using a small screwdriver, adjust the  
  temperature up or down:
  a.  By turning the screw ¼ turn to the left will increase the temperature about 20°F.
  b.  Turning ¼ to the right will decrease the temperature by 20°F.
  c.  To set the thermostat precisely at 200°F, insert a thermometer probe into the water jacket through  
    the steam hole (just under the sprayhead). Turn the screw ½ turn to the left. 
  d.  When the thermometer reaches 200°F, slowly turn the adjustment screw to the right until the pilot  
    light turns off.
