Lochinvar & A.O. Smith 100163241 Condensate Trap

As a seasoned technician, you know that a failed condensing boiler trap is more than just a nuisance; it is a risk to the secondary heat exchanger and overall system pressure. The Lochinvar & A.O. Smith 100163241 Condensate Trap is a critical OEM component designed specifically for high-efficiency Knight heating boilers (models KBN081 through KBN211) and Armor water heaters (AW150–211). Built from heavy-duty, chemical-resistant plastic, this condensate management assembly ensures acidic effluent is safely collected and discharged, preventing the "slugging" or backup that leads to premature component corrosion and burner instability. Replacing a cracked or clogged Lochinvar 100163241 with this genuine OEM HVAC replacement part restores the proper factory-spec drainage required for peak AFUE performance. Whether you are performing a seasonal teardown or addressing a "blocked drain" error code, utilizing this exact A.O. Smith boiler part guarantees a seamless 8.5" x 11" fitment without the need for field-modified piping solutions.

• Precision OEM Fitment: Designed as a direct drop-in replacement for Knight KBN and Armor AW series units, eliminating the need for universal trap adapters.
• Enhanced Corrosion Resistance: Constructed from high-grade polymers to withstand the low PH levels of flue gas condensate produced by high-efficiency combustion.
• Optimized Drainage Flow: Engineered internal geometry prevents air-locking and ensures a continuous flow to the neutralizer or floor drain.
• System Protection: Effectively isolates the combustion chamber from the drainage system, maintaining the critical pressure seal required for safe operation.

Which specific boiler models are compatible with this trap?
This 100163241 condensate trap is the direct replacement for Lochinvar Knight models KBN081, KBN106, KBN151, and KBN211, as well as A.O. Smith/Lochinvar Armor AW150, AW151, AW199, and AW200 units.

Can I use this for the larger 285 or 286 models?
No. For the Knight KB 286 or KH 285 models, you typically require the 100163244 trap. Always verify your specific model and serial number against the HVAC part specifications to ensure the internal float and port sizes match.

Does this assembly include the mounting hardware or hoses?
This SKU generally covers the main condensate trap assembly. If your existing 2-inch plastic drain lines or hose clamps are degraded, we recommend inspecting those separately during the installation of the new Lochinvar 100163241.
