The Bard 8620-111A Direct Vent Check Valve is an OEM safety component used in Bard direct-vent gas heating systems to maintain proper venting by preventing unwanted backflow through the vent or air intake path. A worn or sticking check valve can contribute to ignition or draft-related faults, nuisance shutdowns, or inconsistent heater operation, so replacing it with the correct Bard part helps restore reliable vent performance and supports proper combustion airflow. Because direct-vent hardware can vary by model and vintage, confirm compatibility using your unit model and serial number and the Bard service literature before ordering Bard 8620-111A.
Please call for available options or find replacement parts.
