Resideo ARD7TZ Damper 326010-701 If the burners light butThe Resideo ARD7TZ is a 7 inch automatic round damper engineered specifically for high efficiency forced air zoning. This 24Vac zone damper features galvanized steel construction and a single blade design that seats tightly against a gasket to ensure minimal leakage (less than 1% at 0. 5 in. WC). Built for fail safe operation, the actuator is normally open, using a power closed spring return open mechanism. This ensures that in the event of a power
