Lochinvar & A.O. Smith 100111048 Blower Assembly
The Lochinvar & A.O. Smith 100111048 Blower Assembly is a high-performance combustion air inducer designed for commercial 120V water heating systems. Engineered for precise air-fuel mixture delivery, this 3250 RPM blower motor is critical for maintaining the high-efficiency operation of BTH, SUF, and HCG series commercial water heaters. As a direct OEM replacement for part number 9006272005, this assembly ensures drop-in compatibility and restores factory-spec venting performance. The robust construction supports continuous duty cycles, pulling combustion air through the heat exchanger to facilitate optimal heat transfer. For technicians, installing this genuine Lochinvar blower means ensuring stable pressure switch operation and preventing common "Ignition Failure" codes caused by insufficient airflow. Whether you are servicing a natural gas or propane unit, this forced draft blower provides the consistent static pressure required for clean combustion and efficient exhaust venting in demanding light industrial environments.
Key Benefits- OEM Compatibility: Guaranteed fit for A.O. Smith BTH 120 models and compatible Lochinvar commercial water heaters.
- High-Speed Performance: Operates at a consistent 3250 RPM to maintain necessary flue gas velocity and prevent condensation buildup in the venting system.
- Direct Replacement: Replaces obsolete part 9006272005, utilizing standard 120V power and existing wiring harnesses for faster field installation.
- Reliable Combustion: Specifically designed to handle the high static pressure requirements of helical coil heat exchangers found in ultra-high efficiency units.
What models is the 100111048 blower assembly compatible with?
This blower is primarily used in A.O. Smith Cyclone BTH, SUF, and HCG models, specifically in the 60-120 size range. It is the standard replacement for the Lochinvar 100111048 and the discontinued 9006272005 assembly.
How do I troubleshoot a failing blower motor on a commercial water heater?
If the unit displays an "Airflow Proving" or "Pressure Switch" fault, first check the 3-pin connector and verify 120VAC power. Ensure the impeller rotates freely; restricted movement or excessive humming often indicates bearing failure or warped blades from overheating.
Can this blower be used with both Natural Gas and Propane units?
Yes, this combustion blower assembly is rated for use in both gas types, as its primary function is the management of combustion air and flue gas movement rather than fuel metering.
