Reznor 164542 Motor and Wheel

The Reznor 164542 Motor and Wheel is a high-performance venter motor assembly designed for critical venting and exhaust applications in industrial heating units. Built for compatibility with Reznor CAUA models 350 to 400, this 115V draft inducer ensures consistent static pressure and reliable combustion air delivery. As a technician-grade OEM replacement motor, the 164542 eliminates the vibration and noise issues common with generic aftermarket assemblies. This centrifugal blower motor and wheel combination is engineered for high-duty cycles, maintaining flue gas velocity to prevent safety lockouts. When performing a swap out, ensure a 5/16-inch gap between the venter wheel and the mounting plate to secure efficient airflow. This assembly is a drop-in solution for maintaining the structural integrity of your industrial heating system while optimizing thermal efficiency.

• OEM Compatibility: Exact fit for Reznor CAUA 350-400 units ensures no field modifications are required.
• Optimal Airflow: Precision-balanced wheel maintains proper draft inducer pressure for safe combustion.
• Rugged Construction: Industrial-grade housing and motor bearings designed for high-heat environments.
• 115V Efficiency: Optimized electrical profile for low amperage draw and reduced operational heat.

Is this a direct replacement for my Reznor unit?
Yes, this is the factory-authorized venter motor and wheel for CAUA series heaters (sizes 350-400). Always check your model plate before installation.

Does the assembly include the mounting hardware?
This kit typically includes the motor and wheel; it is standard practice to retain existing shroud hardware for secure mounting to the heat exchanger cabinet.

What causes typical venter motor failure?
Bearings often fail due to prolonged exposure to high-temperature combustion gases or accumulation of flue debris on the centrifugal wheel, leading to imbalance and noise.
