Reznor 221159 Vent Motor

For HVAC contractors maintaining high-efficiency gas-fired heating systems, the Reznor 221159 Vent Motor is the critical OEM replacement induction motor required to restore proper exhaust ventilation and combustion airflow. Operating on a standard 115V power supply, this 1/4 HP blower motor is engineered for high-demand applications, delivering a fixed speed of 3400 RPM to ensure consistent flue gas extraction. This centrifugal venter motor is built with professional-grade internal components to withstand the high thermal stress conditions found in Reznor unit heaters. It is a direct fit for Reznor model 221240 and various industrial air handling units, ensuring that draft inducer performance remains within factory specifications for safe appliance operation. Precise balance and durable construction minimize vibration during high-speed operation, which is essential for preserving the integrity of the heat exchanger and maintaining combustion efficiency in commercial environments.

• OEM Compatibility: Specifically designed as a direct Reznor 221159 replacement for 115V combustion systems, ensuring a precise fit without modification.
• High-Speed Performance: Delivers a consistent 3400 RPM to maintain necessary static pressure for effective flue gas exhaustion.
• Standard Electrical Specs: Operates on 115V with a 1/4 HP rating, making it compatible with standard commercial unit heater wiring.
• Rugged Build: Constructed to handle the continuous duty cycles required for HVAC ventilation motors in industrial settings.

Is the Reznor 221159 compatible with non-Reznor units?
While this 115v 1/4hp 3400rpm vent motor is an OEM part for Reznor equipment like model 221240, contractors should verify shaft diameter and mounting patterns if attempting to use it as a cross-reference for other unit heaters.

What are the symptoms of a failing Reznor venter motor?
Common indicators include loud bearing noise, intermittent starting, or a pressure switch fault code on the furnace control board, signaling insufficient draft inducer airflow.

Does this motor include the fan wheel?
This part number typically refers to the motor itself. When replacing a 221159 vent motor, technicians should inspect the existing centrifugal blower wheel for corrosion or debris that could unbalance the new motor.
