Lochinvar & A.O. Smith 100190481 Gasket Kit
Maintaining a high-efficiency combustion seal is critical for the safety and performance of commercial boilers and water heaters. The Lochinvar & A.O. Smith 100190481 Burner Gasket Kit is the essential service components required to reseal the burner assembly to the heat exchanger. This specific kit serves as the factory-authorized updated version for GKT30018, engineered to handle the high thermal loads and pressure differentials found in Lochinvar Knight and A.O. Smith burner configurations. By replacing these HVAC burner gaskets during annual preventative maintenance, contractors can effectively prevent gas leaks and ensure optimal airflow for combustion efficiency. These high-density OEM replacement parts are designed to withstand degradation better than older-style GKT30018 gaskets, providing a reliable, tight seal between the burner door and the combustion chamber. When your Lochinvar burner gasket begins to dry out or crumble, it can lead to dangerous flue gas recirculation or CO leakage; this 100190481 kit provides the exact tolerances needed for Lochinvar furnace parts compatibility and long-term system stability.
Key Benefits:
- Direct OEM Replacement: Seamlessly replaces the legacy GKT30018 part number with improved material composition.
- Leak Prevention: Forms a critical high-temperature seal to prevent the escape of toxic flue gases into the mechanical room.
- Combustion Optimization: Ensures proper internal pressure and air-to-fuel ratios by eliminating unmetered secondary air intake.
- System Longevity: Helps protect the burner door and mounting hardware from heat damage and oxidation.
Common Questions:
Is 100190481 directly compatible with units using the GKT30018?
Yes, the 100190481 is the official superseding part number for the GKT30018. It is designed to fit the same footprint while offering updated material specifications for better heat resistance.
When should these gaskets be replaced?
Technicians should inspect the burner gasket during every annual teardown. If the gasket appears brittle, discolored, or shows signs of thinning, it must be replaced to maintain safe operation.
Can I use high-temp RTV silicone instead of this kit?
No. HVACR professionals must use the 100190481 Gasket Kit to ensure the specific thickness and compression required for Lochinvar Knight and A.O. Smith boilers. RTV does not provide the same structural integrity under high-pressure combustion.
