Lochinvar & A.O. Smith 100233587 Burner Gasket

When you are performing annual maintenance on a high-efficiency Lochinvar Knight or A.O. Smith system, ensuring a gastight seal at the burner assembly is non-negotiable. The Lochinvar & A.O. Smith 100233587 Combustion Burner Gasket is the professional-grade OEM solution designed to prevent the escape of hazardous combustion byproducts and maintain the precise pressure balance required for condensing boiler efficiency. This specific boiler burner gasket is a direct replacement for legacy part numbers GKT2429 and GKT2429K (and cross-references to 100146534), ensuring a perfect fit without the need for field modifications.

Constructed to handle the high-temperature environment of the combustion burner assembly, this replacement burner gasket is critical for technicians servicing A.O. Smith water heaters and Lochinvar heating units. A compromised seal in this area can lead to inconsistent flame signals, CO leakage, or reduced thermal transfer. Utilizing this HVAC combustion seal ensures your repair meets factory specifications, providing the reliability your commercial and residential clients demand. For the veteran contractor, keeping these in the van is a standard practice for resolving Lochinvar GKT2429 compatibility issues during burner cleaning or heat exchanger inspections.

• OEM Compatibility: Seamlessly replaces legacy part numbers 100146534, GKT2429, and GKT2429K for a guaranteed fit.
• High-Temperature Durability: Engineered to withstand the rigors of the combustion chamber without degrading or losing seal integrity.
• System Safety: Prevents the leakage of flue gases and ensures internal pressure remains within manufacturer tolerances.
• Precision Fit: Pre-cut to bridge the interface between the burner assembly and adjacent surfaces for easy installation.

Is the 100233587 an exact replacement for the GKT2429?
Yes, it is the direct successor. The manufacturer updated the part number, but the dimensions and material specifications remain identical to the original GKT2429 and the GKT2429K kit.

Should I replace this gasket every time I pull the burner?
Technicians generally recommend replacing the burner gasket whenever the donor assembly is removed for cleaning or inspection. Reusing a compressed gasket can result in micro-leaks that affect combustion analysis results.

Does this gasket fit both A.O. Smith and Lochinvar units?
Correct. Since both brands share common platforms for many high-efficiency boilers and water heaters, this part is the standard combustion seal for various models across both lines.
