Description
The York S1-028-18912-000 is an OEM condensate trap engineered specifically for Ultra Low NOx (ULN) furnace applications. Designed to meet the precise drainage requirements of high-efficiency, low-emission York furnace systems, this condensate trap ensures proper removal of acidic condensate produced during the combustion process — protecting your heat exchanger, inducer, and overall system integrity.
Key Features
- OEM York replacement part — direct-fit for Ultra Low NOx furnace models
- Engineered to handle acidic condensate generated by high-efficiency combustion
- Maintains proper pressure differential across the inducer assembly
- Prevents flue gas bypass and protects downstream components
- Durable construction for long-lasting, reliable performance
- Exact OEM specifications ensure hassle-free installation
Why Condensate Trap Maintenance Matters
In high-efficiency and Ultra Low NOx furnaces, the combustion process produces water vapor that condenses into acidic liquid. A properly functioning condensate trap is critical to safely channeling this condensate away from the heat exchanger and inducer motor. A failed or clogged trap can lead to nuisance lockouts, inducer damage, or compromised flue gas venting — making timely replacement with a genuine OEM part essential.
