remove the knob without moving the thermostat shaft. Place narrow bladed screwdriver 
(1/8”) into the hollow thermostat shaft and engage center adjustment screw. When 
thermometer reading approaches 198F slowly turn the adjustment screw clockwise until 
the burner goes out. Turning the screw counter-clockwise will increase the 
temperature.  
 
REPLACING SOLENOID VALVE: 
1.

 

Shut off water supply and disconnect power to the boiler.
