Lochinvar & A.O. Smith 100188938 Assembly

The Lochinvar & A.O. Smith 100188938 Assembly, specifically identified as the GASKETBURNER2 ASSY, is a critical OEM component designed to maintain the structural and thermal integrity of the combustion seal. This burner gasket assembly is engineered for high-recovery gas-fired systems, ensuring a gas-tight interface between the burner flange and the combustion chamber. In the field, a compromised seal leads to erratic CO2 levels and reduced thermal efficiency. This assembly is a direct replacement burner gasket for the Lochinvar Copper-Fin II series and various A.O. Smith commercial water heaters, providing the high-temperature resistance required to prevent flue gas bypass. For senior technicians, this part is essential during annual teardowns to ensure the heating system operates at peak combustion analysis specs. Using genuine Lochinvar parts like the 100188938 ensures proper compression and fit, eliminating the risk of hazardous leaks or localized overheating within the cabinet.

• Ensures a high-temperature seal between the burner and chamber to prevent gas leakage.
• Maintains optimal combustion efficiency by eliminating secondary air infiltration.
• Engineered specifically for commercial HVAC equipment and high-output water heaters.
• Durable OEM construction withstands the extreme thermal cycling of Copper-Fin II units.
• Facilitates accurate combustion analysis and stable flame monitoring.

When should the 100188938 burner gasket be replaced?
Industry best practice dictates replacing the burner gasket assembly whenever the burner is removed for inspection or if there is visible evidence of hardening or "heat-checking" on the material.

Is the GASKETBURNER2 ASSY compatible with both Natural Gas and LP units?
Yes, this replacement part is designed to function with both fuel types as it seals the combustion area regardless of the gas manifold configuration.

What happens if the burner gasket is not seated properly?
An improper seal can cause improper fuel-to-air ratios, potential roll-out conditions, and may trigger flame failure or pressure switch errors on the control board.
