Lochinvar & A.O. Smith 100135311 Burner

Lochinvar & A.O. Smith 100135311 Burner

Professional contractors understand that maintaining high-efficiency combustion in Lochinvar Knight and Armor systems requires precision components. The Lochinvar & A.O. Smith 100135311 Burner Assembly is a critical OEM replacement part designed for high-capacity boilers and water heaters, including the KBX501, KBX601, KBX701, and KBX801 models. Built with a 1/2-inch NPT connection and stainless steel construction, this burner assy ensures consistent flame patterns and optimal heat transfer while resisting the corrosive effects of condensation in high-efficiency condensing boilers. As a direct replacement for obsolete part numbers BNR3429, BNR2411, and 100135239, it facilitates a seamless mechanical fit and restores factory-spec combustion efficiency. Whether you are servicing a Lochinvar Knight XL or an A.O. Smith Cyclone water heater, this dedicated assembly is engineered to handle the rigorous duty cycles of commercial and heavy residential applications, ensuring your gas-fired heating system operates at peak performance without the risk of improper air-to-fuel ratios or flame instability.

Key Benefits for Technicians:
  • Direct OEM Compatibility: Engineered specifically for Lochinvar Knight, Armor, and Shield models (399-501 series) to ensure safe burner ignition.
  • Durable Construction: Features stainless steel components to maximize service life within the high-moisture environment of condensing heat exchangers.
  • Seamless Retrofit: Functions as the factory-authorized successor to BNR3429, eliminating the need for field modifications or manifold adjustments.
  • Improved Combustion: Maintains precise flame geometry to prevent carbon monoxide buildup and ensure compliance with strict emission standards.
Common Questions:

What models are compatible with the 100135311 burner?
This burner assembly is frequently used in Lochinvar KBX501-801, SNA201-100, and AWH0500NPM units. It is the standard replacement for large-scale Knight and Armor heating systems.

Does this assembly include the necessary gaskets?
Yes, technicians should always verify that the mounting gaskets are included or sourced separately; installing this burner assy with a degraded seal can lead to dangerous flue gas leakage.

Can I use this to replace a BNR3429 burner?
Yes, the 100135311 is the official Lochinvar replacement part for the now-superseded BNR3429 and BNR2411 numbers.
