Lochinvar & A.O. Smith 100189053 Collar
The Lochinvar & A.O. Smith 100189053 Collar (also identified as KCOLLARFLUE3) is a critical 3-inch flue component engineered for precise integration with commercial and industrial heating systems. Specifically designed for Lochinvar AWN series boilers—including models such as the AWN151PM, AWN200PM, and AWN201PM—this OEM flue collar kit ensures a secure transition between the boiler’s heat engine and the venting assembly. Constructed to withstand operational stresses and acidic condensate, the kit includes the collar, mounting screws, and a high-temperature gasket to maintain a gas-tight seal, preventing the leakage of combustion byproducts into the mechanical room. For HVACR contractors, installing this 3-inch K-collar is essential for resolving airflow issues or replacing deteriorated original parts that may lead to F03 air pressure switch faults or flue sensor warnings. Utilizing genuine Lochinvar replacement parts ensures that the combustion exhaust is efficiently expelled, maintaining the factory-specified performance and safety standards of the venting system.
Key Benefits- Precise OEM Fit: Specifically engineered for Lochinvar AWN series and select A.O. Smith boiler models for a seamless, leak-proof connection.
- Enhanced Gas Containment: Includes a dedicated gasket and hardware to ensure a tight flue seal, preventing carbon monoxide and moisture leakage.
- Robust Construction: Built to endure the high-temperature and corrosive environment of condensing boiler exhaust systems.
- Simplified Installation: Standard 3-inch diameter design allows for straightforward replacement during routine maintenance or emergency repairs.
Which boiler models are compatible with this collar?
This part is the primary 3-inch flue collar for Lochinvar Knight AWN models (AWN151PM, AWN200PM, AWN201PM) and compatible A.O. Smith commercial units requiring the 100189053 part number.
What is included in the KCOLLARFLUE3 kit?
The kit typically includes the 3-inch flue collar, two mounting screws, and the necessary sealing gasket to ensure a pressurized, airtight fit.
Can this part fix an F03 fault code?
An F03 fault is often triggered by air inlet issues or blocked exhaust pathways. Inspecting and replacing a damaged or improperly sealed 100189053 collar is a key troubleshooting step for restoring proper pressure switch operation.
