Lochinvar & A.O. Smith 100189054 Collar
The Lochinvar & A. O. Smith 100189054 Collar is a precision-engineered 4" flue collar essential for maintaining the structural integrity of high-efficiency venting systems. As an OEM component, this kit provides a secure, gas-tight transition between the appliance and the exhaust infrastructure, preventing hazardous leaks and ensuring optimal draft performance. This specific part is a direct replacement for legacy units, as 100189054 is identical to JKB30111, JKB2001, and 100149667, making it a critical item for service trucks handling Lochinvar Knight boiler repair or SHIELD water heater maintenance. Designed for compatibility with leading condensing units like the SNA286-501 and KBN400-601 series, its stainless steel construction resists the corrosive effects of acidic condensate. Utilizing a genuine Lochinvar replacement part ensures your installation remains up to code while maximizing the combustion efficiency of industrial and commercial heating systems for long-term operational reliability.
Key Benefits- Universal Compatibility: Serves as the exact OEM substitute for part numbers 100149667, JKB2001, and JKB30111.
- Corrosion Resistance: High-grade material construction withstands high-temperature exhaust and acidic flue environments.
- Optimized Venting: Ensures a 4-inch precision fit to facilitate safe and efficient gas expulsion from the heat exchanger.
- Seamless Integration: Engineered specifically for Lochinvar Knight and A. O. Smith SHIELD models to maintain equipment UL/CSA certifications.
- Is this collar compatible with both boilers and water heaters? Yes, it is designed for use across specific Lochinvar Knight Boilers (KBN series) and A. O. Smith SHIELD Water Heaters (SNA series).
- Do I need additional gaskets for installation? While this kit provides the primary collar, always inspect factory seals during flue collar replacement; if the existing gasket is compressed or brittle, it should be replaced to ensure a gas-tight seal.
- Does this fit 3-inch venting? No, this is a dedicated 4" flue collar. Using adapters to downsize venting must comply with specific manufacturer equivalent length calculations.
