Velocity Boiler Works (Crown) 960126 Switch Refrigerant and air handler applications whereThe Velocity Boiler Works 960126 Blocked Vent Switch is a critical safety component designed for gas fired natural draft boilers, specifically the Crown BSI and CWI series. Engineered to act as a spill switch, this assembly monitors flue gas conditions within the draft diverter or relief opening. When a chimney obstruction or downdraft occurs, heat builds up at the sensor location; once the 220F activation temperature is reached, the switch opens the
