ABSTRACT:
A thermally activated vent damper assembly for occluding passage of gases in a passageway such as a flue. The assembly includes first and second damper members which are pivotable about a common axis. Coaxial first and second support members which are spaced apart along the common axis support thermally activated biasing members which are attached to the damper members to thereby suspend the damper members within the flue. When heated, the biasing members pivot the first and second damper members about their common axis from a flue closing orientation to a flue opening orientation. The assembly may include a housing mountable to the flue and to which the first and second support members are attached.
