Velocity Boiler Works (Crown) 233081 Flue Sensor Kit

The Velocity Boiler Works 233081 Flue Sensor Kit is an essential OEM replacement component engineered for precision monitoring of exhaust gas temperatures in high-efficiency condensing boilers. Designed specifically for the BWC series models BWC070, BWC120, and 151, this kit ensures the control board receives accurate thermal feedback to prevent heat exchanger damage and maintain safe combustion parameters. As a critical safety device, the 233081 flue temperature sensor triggers a system shutdown if flue temperatures exceed the design limits of the venting material, protecting the integrity of the Velocity Boiler Works BWC070-151 installation. For technicians troubleshooting lockout codes or performing annual maintenance, replacing a fouled or drifting sensor with this genuine Crown Boiler flue sensor kit is necessary to restore factory-spec performance. This kit includes the necessary hardware for a direct, drop-in replacement, ensuring low-resistance electrical connectivity and a reliable seal within the flue collector.

Key Benefits

• OEM Compatibility: Exact replacement for Velocity Boiler Works 233081, ensuring seamless integration with the BWC control logic.
• Critical Safety Protection: Continuously monitors flue gas discharge to prevent overheating and potential vent system failure.
• System Calibration: Provides the precise thermistor resistance curves required for accurate BWC070-120-151 temperature modulation.
• Durable Construction: Built to withstand the corrosive environment of acidic condensate and high-velocity exhaust gases.
• Contractor Ready: Complete kit facilitates rapid field replacement, reducing diagnostic time and improving first-fix rates.

Common Questions

Which boiler models use the 233081 sensor?
This kit is purpose-built for the Velocity Boiler Works (formerly Crown Boiler) BWC series, specifically the BWC070, BWC120, and BWC151 condensing gas boilers.

What are the symptoms of a failing flue sensor?
Common indicators include intermittent lockouts, specific "Flue Sensor Open" or "Flue Sensor Shorted" error codes on the boiler display, or the burner failing to fire despite a call for heat.

Is this a universal HVAC part?
No, this is a dedicated Velocity 233081 flue sensor. Using non-OEM or third-party thermistors can lead to incorrect temperature readings, improper modulation, or unsafe operating conditions.
