ABSTRACT:
A fireplace draft eliminator is provided for a fireplace having an opening in a front face about a hearth, and consists of a rear plate being of the same size and shape as the opening, so as to fit into the opening. An internal support frame is slightly smaller in size and shape as the rear plate and is attached to a front surface of the rear plate. A resilient gasket is mounted on the periphery of the internal support frame. The internal support frame and the gasket together are of the same size and shape as the rear plate, so as to also fit into the opening, with the gasket forming a seal about the opening and the hearth. A front plate is of generally the same shape as, but of greater marginal extent in height and width than the opening. The front plate is attached to a front surface of the internal support frame, so that the front plate can cover the opening and rest flat against the front face of the fireplace to eliminate the draft through the opening, when the fireplace is not being used. When the draft eliminator 10 is fabricated out of all fireproof materials it can also be used to choke out a fire in a fireplace when unusual down draft conditions cause smoke and gases to be undesirably forced back into a dwelling.
