Description
The Lochinvar & A.O. Smith 100233694 Gas Train Gasket Kit furnishes a matched set of venturi seals covering every flanged junction along the gas train channel. compresses between mating faces at the venturi inlet, blower outlet, and adjacent transition points, blocking any bypass route where unmetered air could escape the intended flow path in HVAC systems. Laid into their respective grooves at each intersection during burner disassembly, a microleak at any venturi interface skews the air-to-gas ratio reaching the burner, producing incomplete combustion and elevated carbon monoxide output that interrupts heating cycles until each affected surface achieves a verified, pressure-retaining closure.
