Lochinvar & A.O. Smith 100111049 Blower Assembly

The Lochinvar & A.O. Smith 100111049 Blower Assembly is a direct OEM replacement engineered for high-efficiency commercial water heaters, specifically the BTH 150, SUF 150, and HCG 150 series. Built for performance in both natural gas and propane applications, this combustion blower ensures the precise air-to-fuel ratio necessary for optimal heat exchange and venting. For a veteran technician, this assembly is the go-to solution when encountering common BTH-150 fault codes like "Blower Prover Open" or "BE-1 No Blower Feedback." Replacing a failing motor or a seized blower wheel with this genuine 100111049 unit restores the system's ability to maintain the correct static pressure required by the Central Control Board (CCB). This assembly includes the motor and housing designed to withstand the high-demand cycles of vertical and horizontal venting systems in commercial environments, ensuring the safety of the hot surface igniter sequence by consistently closing the Blower Prover Pressure Switch.

• Broad Compatibility: Engineered as a precise fit for BTH-150, SUF-150, and HCG-150 models, correcting issues with obsolete part numbers like 9006273005.
• Optimized Combustion: Delivers the exact CFM required for high-efficiency condensing water heaters, reducing carbon buildup and maximizing fuel economy.
• Plug-and-Play Integration: Designed for seamless communication with the iCOMM diagnostics system and standard 120V, 60-Hz power supplies.
• Dual Fuel Versatility: Fully rated and safety-tested for use in both Natural Gas and Liquid Propane (LP) configurations.
