The AO SMITH 100266139 is a condensate trap kit designed to manage and drain condensate water produced during the combustion process in high-efficiency water heaters and boilers. Condensate traps prevent flue gases from escaping through the drain line by maintaining a water seal, ensuring safe and code-compliant venting. This kit is installed by licensed plumbers and HVAC technicians servicing condensing appliances where acidic condensate must be properly captured and routed to a drain.
The 100266139 condensate trap kit is suited for residential and light commercial condensing water heater installations where proper condensate management is required. High-efficiency condensing appliances generate significant amounts of acidic condensate during normal operation, and a functional trap is essential for safe drainage and venting integrity. Installation is typically performed during appliance setup or as part of a service call when the original trap is damaged or missing.
Designed as an OEM-style replacement condensate trap kit for AO SMITH condensing water heaters and boilers requiring condensate drainage management.
Installation should be performed by a licensed plumber or HVAC technician familiar with condensing appliance venting and drain requirements. Shut off the appliance and allow it to cool before removing or replacing any condensate components. Ensure the drain line maintains proper slope for gravity drainage per local plumbing codes. Verify the trap is primed with water before returning the appliance to service.
