Lochinvar & A.O. Smith 100110206 Pilot Burner

The Lochinvar & A.O. Smith 100110206 Pilot Burner is a critical replacement component engineered for precision ignition in high-efficiency water heaters and boilers. This assembly functions as the primary pilot burner for Lochinvar units, ensuring consistent flame rectification and pilot stability. It serves as the direct 9004963215 replacement pilot, addressing common ignition failures and intermittent flame sensing issues found in aging systems. Built to withstand the thermal stresses of continuous operation, this HVAC pilot assembly is compatible with a wide range of A.O. Smith commercial and residential models. When diagnosing a water heater pilot won't stay lit scenario, verifying the millivolt output or flame signal from this component is essential. Utilizing OEM 100110206 burner parts maintains the manufacturer's specified air-to-fuel ratio, preventing carbon buildup and premature thermocouple degradation. For contractors, installing this A.O. Smith ignition component ensures optimal pilot burner compatibility and restores the system to factory performance levels without the need for field modifications.

Key Benefits

• Direct OEM Integration: Engineered as a drop-in replacement for part number 9004963215, ensuring proper alignment and mounting.
• Stable Flame Pattern: Optimized orifice design provides a consistent pilot flame for reliable main burner ignition.
• Enhanced Durability: Constructed from high-grade alloys to resist oxidation and thermal fatigue in high-temperature combustion chambers.

Common Questions

How do I confirm if this pilot burner fits my specific model?
Verify your unit's model number and series on the rating plate. The 100110206 is a standard replacement for many Lochinvar and A.O. Smith units originally equipped with the 9004963215 assembly.

What are the signs that a pilot burner assembly needs replacement?
Look for signs of heavy oxidation on the pilot hood, a "lazy" yellow flame, or the inability to generate enough millivolts to keep the gas valve open.

Does this assembly include the orifice?
Yes, this is a complete pilot burner assembly designed to deliver the specific BTU output required for the pilot circuit.
