ABSTRACT:
A gas fueled direct vent fireplace having a firebox within which flue gases are generated includes a glass face access door for closing the front of the fireplace and facing the interior of a room within which the fireplace is located. Flue gases exit remote from the front. A first seal is positioned about the periphery of the open front of the fireplace at locations accessible to flue gases for abutting the glass. A second seal is positioned about the periphery of the glass outwardly of the first seal so that only flue gases which leak past the first seal may contact the second seal. The first seal is formed from fiberglass which has high temperature characteristics. The second seal is formed from a silicone elastomeric material. With this arrangement leakage of hot gases into the adjoining room is substantially eliminated and the life of the elastomeric seal may be extended indefinitely relative to that of the prior art.
