Application
This automatic vent damper is intended for use with Utica-Dunkirk boilers and heating appliances that require an 8″ flue connection. By automatically blocking the flue when the heating system is in standby, it minimizes the chimney draft effect that draws heated air out of the building — a simple but effective upgrade for maintaining system performance. Always verify compatibility with your specific Utica-Dunkirk model before installation.
