Lochinvar & A.O. Smith 100288517 Valve
This Lochinvar & A.O. Smith 100288517 Flap Valve Assembly is a critical component for maintaining peak performance in high-efficiency commercial boilers and water heating systems. As a genuine OEM replacement part, this flapper stabilator valve is engineered to regulate combustion air and exhaust flow, preventing hazardous backflow that can compromise heat exchanger integrity. The assembly includes the heavy-duty flap valve mechanism, a precision-fit gasket, and a dedicated stabilizer to ensure quiet operation and a consistent seal under varying pressure differentials. For technicians servicing Knight or other compatible high-recovery units, installing this 3.07 lb assembly is essential for restoring factory-spec thermal efficiency and ensuring the integrated control module can accurately manage the burner flame without interference from turbulent airflow. Rely on this 100288517 valve assembly to eliminate 24V power faults and air pressure switch blockages, keeping your customers' critical heating infrastructure operational and secure.
Key Benefits- Prevents Backflow: Ensures unidirectional combustion gas flow to protect internal components.
- OEM Precision: Guaranteed compatibility with Lochinvar Knight and A.O. Smith performance specifications.
- System Efficiency: Minimizes turbulence and equipment wear by maintaining stable pressure within the combustion chamber.
- Complete Kit: Includes the essential gasket and stabilizer for a leak-free, drop-in replacement.
Is this part compatible with my specific Lochinvar Knight model?
The 100288517 is designed for a wide range of high-efficiency boilers. You should verify the part number in your specific unit’s service manual to ensure it matches the flap valve assembly required for your BTU rating.
What are the symptoms of a failing flap valve?
Common signs include loud "clapping" noises during ignition, nuisance air pressure switch trips, or soot buildup due to improper air-to-fuel ratios caused by a stuck or degraded flapper.
Does this assembly include the replacement gasket?
Yes, this OEM assembly includes the valve, the flap mechanism, the stabilizer, and the necessary gasket to ensure an airtight seal upon installation.
