Reznor 236159 Ventor Motor

The Reznor 236159 Ventor Motor is the heavy-duty OEM combustion air solution for high-capacity unit heaters. As a direct 115V venter motor replacement, this unit is the designated engineered successor for the discontinued 196236 part number. Running at a high-speed 3000 RPM, this 1/5 HP motor features a 3.3 frame and an Open Air Over (OAO) enclosure designed to maintain optimal thermal regulation during continuous combustion cycles. Technical staff should note the specific 1/4" x 2-1/2" shaft dimensions, which ensure precise alignment with the existing blower wheel assembly in Reznor UDAP and UDAS series units, specifically the 300, 350, and 400 models.

Replacing a failing draft inducer motor with this genuine HVAC combustion motor restores critical static pressure and prevents pressure switch trip errors that lead to system lockout. This single-phase, 60Hz motor provides the reliable exhaust flow necessary for safe operation in industrial and commercial heating applications. By utilizing the direct replacement for 196236, contractors ensure full mechanical compatibility without the need for field modifications or bracket adjustments.

• OEM Compatibility: Specifically engineered for Reznor UDAP-300, UDAS-350, and UDZ-400 series gas-fired heaters.
• High-Performance Output: Delivers a consistent 3000 RPM at 2.7 Amps to ensure proper venting of flue gases.
• Streamlined Installation: Direct drop-in replacement for legacy part 196236, reducing downtime on the job site.
• Reliable Construction: Features 3.3 frame sizing and OAO enclosure for durability in high-cycle environments.

Is the blower wheel included with this motor?
No, the Reznor 236159 is the replacement venter motor only. You must retain your existing blower wheel or source one separately if the original is fouled or unbalanced.

What are the signs that my current 196236 motor needs replacing?
Look for unusual bearing noise, failure to reach 3000 RPM, or the heater timing out on a pressure switch error during the pre-purge cycle.

Does this motor support 230V applications?
This is a dedicated 115V ventor motor. Always verify the voltage at the inducer leads before installation to prevent winding damage.
