The AO SMITH 100266140 is a condensate collector designed to capture and channel condensate generated during water heater or boiler operation. Condensate collectors are a critical drainage component in high-efficiency heating systems, directing moisture away from the heat exchanger and internal components to prevent corrosion and water damage. This part is typically installed by licensed plumbers or HVAC technicians during new equipment installation or as a replacement during routine service.
The 100266140 is suited for use in residential and light commercial applications where condensate management is required. High-efficiency gas appliances that operate in condensing mode produce acidic condensate as a byproduct of combustion, making a properly functioning collector essential for system longevity and safe operation.
Designed as an OEM-style replacement condensate collector for AO SMITH water heater and boiler systems requiring condensate drainage components.
Installation should be performed by a licensed plumber or HVAC technician. Before servicing, shut off the gas supply and electrical power to the appliance and allow the unit to cool completely. Ensure the condensate drain line is clear and properly pitched to allow gravity drainage per local plumbing codes. Consult the appliance service manual for proper seating and fastening of the collector before returning the unit to service.
