Lochinvar & A.O. Smith 100173796 Assembly
The Lochinvar & A.O. Smith 100173796 Gas/Air Arm Assembly is a critical combustion component engineered for high-efficiency boiler systems. Designed specifically for the Lochinvar Knight KBN150, AWN150, and SNR150 series, this genuine OEM manifold directs the precise mixture of fuel and air into the burner chamber. Maintaining the correct stoichiometric ratio is essential for preventing short-cycling and ensuring the modulating blower operates at peak thermal efficiency. This assembly is built to withstand high-temperature environments, featuring a robust venturi interface and integrated gasket to eliminate vacuum leaks that cause "Air Pressure SW" or "Flame Fail Ign" fault codes during the ignition sequence.
For service technicians, the 100173796 gas air assembly provides an exact fit for the 150,000 BTU models, replacing worn or warped manifolds that compromise combustion stability. Whether you are performing a seasonal teardown or troubleshooting a blocked inlet error, this factory-spec assembly ensures the negative pressure gas valve signals are accurately translated to the burner. Replacing the gas/air manifold with an OEM Lochinvar part is the only way to maintain the 4-14 inches w.c. natural gas operating range and preserve the original equipment’s AFUE rating.
Key Benefits- Precision Air-Fuel Mixing: Optimized venturi design for consistent combustion performance across all modulation stages.
- OEM Compatibility: Exact replacement for Lochinvar Knight KBN150 and A.O. Smith SNR150 commercial boilers.
- Integrated Sealing: Includes high-grade gaskets to prevent dangerous gas bypass and vacuum loss.
- Contractor-Grade Durability: Machined to withstand high-cycle thermal stress in hydronic heating systems.
What models is the 100173796 assembly compatible with?
This part is specifically engineered for Lochinvar Knight and A.O. Smith 150-series units, including the KBN150, AWN150, and SNR150 models.
Does this assembly include the necessary gaskets?
Yes, the 100173796 gas/air arm comes with the required interface gasket to ensure a leak-free seal between the venturi and the blower housing.
Will this fix a "No Flame Proven" error?
While often caused by electrodes, a warped or cracked gas/air manifold can prevent the mixture from reaching the burner correctly, leading to recurring ignition failure codes.
