Velocity Boiler Works (Crown) 960126 Switch
The 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 24V safety circuit to immediately terminate the burner cycle. This prevents toxic combustion byproducts, such as carbon monoxide, from spilling into the mechanical room.
Built for a direct OEM fit, the 960126 assembly includes the thermal disc and the necessary mounting bracket for secure attachment to the boiler breach or heat transfer tube. As a manual reset safety device, it ensures that a technician must inspect the venting system for blockages before the boiler can be placed back into service. Integrating this genuine Crown boiler part maintains the factory-certified safety sequence and prevents the hazardous "short-cycling" issues often seen with improper aftermarket alternatives.
Key Benefits for the Contractor:
- Precision Thermal Sensing: Calibrated to trip at exactly 220 degrees Fahrenheit to maximize safety without nuisance tripping during normal operation.
- Broad Compatibility: Engineered for use with Crown Boiler BSI103, BSI138, BSI172, and CWI series natural draft units.
- Complete Assembly: Comes with the mounting bracket for rapid installation and proper positioning in the flue path.
- OEM Reliability: Provides consistent electrical continuity in 24V control strings, ensuring the gas valve remains closed during vent failure.
Common Questions:
- Does this switch reset automatically? No, this is a manual reset blocked vent switch. If it trips due to high temperatures in the draft hood, a technician must manually depress the reset button after clearing any flue obstructions.
- What causes this switch to trip frequently? Common causes include a blocked chimney, scaled heat exchangers, or insufficient combustion air causing flue gases to spill out of the draft diverter.
- Can I use this on power-vented models? This blocked vent switch assembly is specifically designed for natural draft atmospheric boilers and is not a replacement for air pressure switches used in power-vented or high-efficiency condensing units.
