Ao Smith 100111048 Blower Assembly Natural Propane Gas Bth Suf Hcg 60-120

Product Description

The AO Smith 100111048 is a replacement blower assembly designed for commercial water heaters running on natural gas or propane. It fits the BTH, SUF, and HCG model series in the 60 to 120 gallon range. This blower is a critical component in power-vent and direct-vent water heater systems. It moves combustion air through the burner assembly and exhausts flue gases out of the unit safely and efficiently. Without a properly functioning blower, the water heater cannot complete its ignition sequence or maintain safe combustion. HVAC and plumbing technicians rely on exact OEM replacement parts like this one to restore commercial water heaters to full operation quickly. The AO Smith 100111048 blower assembly is built for high-efficiency commercial applications. Commercial water heaters in the BTH, SUF, and HCG series are commonly found in hotels, apartment buildings, laundromats, and other facilities with high hot water demand. When the blower motor fails, the unit will typically shut down on a pressure switch fault or fail to ignite. Replacing the blower assembly with the correct OEM part ensures the pressure switch circuit is satisfied and combustion airflow meets factory specifications. This assembly is compatible with both natural gas and propane configurations, making it a versatile replacement part for service technicians who work across multiple job sites and fuel types. The unit is rated for high-efficiency operation, meaning it supports the low-excess-air combustion design of these water heaters. Proper blower performance is essential to maintaining the efficiency ratings and safety certifications of the original equipment. Always verify the model number and serial number of the water heater before ordering to confirm compatibility with this blower assembly.
