Abstract: A damper assembly for minimizing heat loss through an exhaust includes a housing mounted within the stack and a bladder received within the housing. The bladder is selectively movable between a first position in which the bladder is deflated and received within the housing, and second position in which the bladder is positioned outside the housing and inflated such that a peripheral surface of the bladder contacts an interior sidewall of the stack to create a gas seal.

Abstract: A damper assembly for minimizing heat loss through an exhaust stack includes a housing mountable within the stack and an umbrella received within the housing. The umbrella is selectively movable between a first position in which the umbrella is received within the housing, and second position in which the umbrella is extended from the housing such that a peripheral edge of the umbrella is in close association with an interior sidewall of the exhaust stack to minimize a flow of fluid past the umbrella and out of the stack.
