This patent describes in combination: a fireplace having a flue and a damper handle; and a fireplace flue sealing device having an inflatable bag-like member with a top and a bottom of a flexible, air impermeable material. The top and the bottom are sealed together about an outer periphery of the member for retaining pressurized air therebetween. The member has selectively slittable sealed areas for permitting the damper handle to pass through a selected one of the areas, the top and the bottom being sealed together about each of the areas. The member is sized and shaped to sealingly engage the fireplace below the flue thereof when inflated; and a closable conduit communicating with the member for admitting pressurized air into the member.
