Lochinvar & A.O. Smith 100110904 Inducer Motor

The Lochinvar & A.O. Smith 100110904 Inducer Motor is a high-performance 120V centrifugal blower assembly engineered specifically for technical replacement in commercial water heaters and high-efficiency boilers. Operating at a fixed speed of 3350 RPM, this OEM draft inducer is critical for maintaining the stoichiometric balance required for clean combustion. It effectively manages the venting of flue gases, ensuring the heat exchanger operates under a consistent negative pressure to prevent exhaust leakage into the mechanical room. Designed as a direct compatible match for A.O. Smith BTH 300A series and various Lochinvar Power-Fin models, this assembly features a corrosion-resistant housing and a precision-balanced wheel to minimize harmonic vibration and bearing wear. For contractors performing scheduled maintenance or emergency repairs, verifying the series and serial number is essential, as this 100110904 blower motor kit is specialized for high-input systems requiring specific static pressure thresholds for safe operation.

• Optimized Combustion Airflow: Delivers a consistent 3350 RPM to ensure proper draft and efficient fuel-to-air ratios in high-BTU applications.
• OEM Compatibility: Exact replacement for A.O. Smith 9006105205 and 100110904, ensuring drop-in fitment without field modifications.
• Industrial Build Quality: Heavy-duty construction designed for the high-cycle demands of commercial condensing water heaters and boilers.
• Reduced Mechanical Noise: Precision-engineered motor components and balanced blower wheels lead to quieter operation and increased hardware longevity.

• Is this motor compatible with LP and Natural Gas units? Yes, the 100110904 inducer is designed to manage flue gases for both fuel types, provided the system is a BTH 300A or equivalent model.
• Does the kit include mounting gaskets? This kit is typically supplied as the blower and motor assembly; it is recommended to inspect existing gaskets and mounting hardware for integrity during installation.
• What are the electrical requirements? This unit operates on a standard 120V single-phase power supply, common in commercial HVAC control circuits.
