Reznor 125345 Mounting Plate

The Reznor 125345 is a critical venter motor mounting plate assembly engineered specifically for high-capacity SC350-400 series unit heaters. As an OEM Reznor replacement part, it ensures the structural integrity and precise alignment of the draft inducer assembly, which is vital for maintaining proper combustion air-flow and safe venting in gas-fired systems. Designed to withstand the thermal stress and vibrational demands of industrial HVAC motor mounts, this plate prevents premature fatigue of the venter housing and blower wheel components.

Field technicians frequently use the Reznor 125345 Mounting Plate during blower motor overhauls or when replacing rusted heating system mounting hardware. Its heavy-gauge construction provides a stable interface between the motor and the heater cabinet, reducing harmonic noise and ensuring the venter assembly remains seated according to factory specifications. This component is essential for contractors performing maintenance on large-scale commercial unit heaters where component drift can lead to efficiency loss or safety switch trips.

Key Benefits:

• Precision Fit: Specifically machined for Reznor SC350 and SC400 models to ensure zero-clearance alignment.
• Vibration Dampening: Rigid design minimizes mechanical resonance, extending the operational life of the venter motor.
• Industrial Durability: Built with corrosion-resistant materials to handle the high-exhaust temperatures typical of gas-fired unit heaters.
• OEM Reliability: Guarantees compatibility with existing factory mounting points without the need for field modifications.

Common Questions:

• What heater models is the Reznor 125345 compatible with? It is primarily designed for the SC series, specifically sizes 350 and 400. It is often required when updating the venter motor assembly on these large-format units.
• Does this include the motor mounting bolts? This part is the mounting plate itself; installers should verify if existing hardware can be reused or if new high-strength fasteners are required for the specific application.
• Why should I replace the plate instead of reusing the old one? Over time, heat cycles and moisture can warp or corrode the original plate, leading to motor misalignment, increased amp draw, and eventual bearing failure.
