Lochinvar & A.O. Smith 100110692 Burner/Sleeve Assembly

The Lochinvar & A.O. Smith 100110692 Burner/Sleeve Assembly is an OEM replacement component designed for high-efficiency commercial boilers and water heaters. Engineered for precise fuel-to-air mixing, this 100110692 burner assembly ensures stable combustion cycles and maintains thermal output integrity in demanding hydronic systems. This assembly is a direct replacement for legacy part numbers such as 9006233005 and is commonly found in Lochinvar Knight and A.O. Smith Cyclone series units. The integrated metal fiber burner sleeve provides a high-surface area for infrared radiation, reducing NOx emissions and preventing flashback. When performing a teardown or heat exchanger inspection, replacing the burner assembly is critical if the sleeve shows signs of fraying, hot spots, or carbon buildup, as these issues compromise the combustion efficiency and can lead to premature ignition failure or pulsing.

Key Technical Benefits

• Precision OEM Fit: Ensures exact clearance within the combustion chamber for uniform heat distribution.
• High-Temperature Durability: The alloy mesh construction resists thermal shock and oxidation during long run cycles.
• Optimized Flame Pattern: Maintains a consistent flame signal to the ionization probe, reducing nuisance lockouts.
• Reduced Emissions: Facilitates a lean-burn process to meet stringent low-NOx compliance standards.

Common Installation Questions

Does this assembly include the mounting gasket?
Standard field practice recommends sourcing the burner mounting gasket separately to ensure a gas-tight seal upon reassembly.

What are the signs of a failing burner sleeve?
Inspect for "hot spots" where the mesh has thinned or darkened significantly, or physical tearing of the fiber, which disrupts the premix flow and causes uneven burning.

Is this compatible with propane (LP) units?
The 100110692 burner is generally compatible with both natural gas and propance configurations, provided the correct orifice and gas valve adjustments are verified according to the manufacturer’s manifold pressure specifications.
