Smith hydronic equipment. The \u003cstrong\u003e100110898\u003c\/strong\u003e silicone burner gasket provides a resilient barrier between the burner assembly and the heat exchanger, ensuring that flue gases remain contained and system pressure is correctly regulated. By replacing a worn or brittle seal with this genuine \u003cstrong\u003e100110898\u003c\/strong\u003e replacement, you prevent leakage and maintain the thermal efficiency of the combustion process.\u003c\/p\u003e\u003cp\u003eThis component utilizes high-grade, heat-resistant silicone material to withstand the extreme thermal cycling inherent in boiler operation. The 3.75-inch diameter ensures a precise mechanical fit, compressing under bolt torque to compensate for minor irregularities on the mounting surface, thereby creating a gas-tight seal that prevents unwanted air infiltration or exhaust discharge.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Resilience:\u003c\/strong\u003e Constructed from high-temperature silicone designed to resist degradation from intense burner heat.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Integrity:\u003c\/strong\u003e Engineered to provide an airtight seal, maintaining optimal combustion chamber vacuum or pressure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMechanical Fit:\u003c\/strong\u003e Precision-molded 3.75-inch diameter ensures consistent contact across the sealing flange.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Compatible with specific Lochinvar and A.O.
