Lochinvar 100233617 - Gas/Air Arm Cover Gasket, Large

Ensuring an airtight seal within the combustion intake assembly is required for maintaining precise fuel-air ratios in high-efficiency boiler systems. The Lochinvar 100233617 cover gasket acts as the primary interface seal for the gas air arm, effectively preventing oxygen infiltration or gas bypass that can destabilize burner performance. By utilizing the original 100233617 replacement, technicians ensure that dimensions strictly adhere to factory tolerances for a seamless, reliable fit.

This gasket is engineered from high-temperature resilient materials designed to accommodate thermal expansion and vibration during frequent burner cycling. It functions by filling microscopic irregularities between the air arm flange and the mounting surface, ensuring that blower-induced pressure remains consistent throughout the combustion process.

Key System Performance Baselines:

• Combustion Integrity: Maintains factory-spec fuel-air ratios by eliminating unwanted air infiltration.
• Thermal Resilience: Resists degradation from constant heat exposure and expansion cycles.
• Vibration Damping: Protects the intake assembly interface against mechanical stress during blower operation.
• Pressure Consistency: Prevents gas bypass to ensure stable blower-induced pressure levels.

⚠️ Application Profile: Specifically designed for gas air arm assemblies in compatible Lochinvar high-efficiency boiler models requiring air-tight intake maintenance.
