ABSTRACT:
The invention relates to a direct vent gas fireplace adapted for attachment to a concentric flue pipe assembly having an exhaust pipe and fresh air pipe. A top wall, rear wall, bottom wall and side walls define a combustion chamber. A gas burner is disposed in the combustion chamber. A slanted flue attachment wall is attached to and extends between the top wall and rear wall. The slanted flue attachment wall is disposed at obtuse angles relative to the top wall and rear wall. A first pipe member is orthogonally attached to the flue attachment wall and is in fluid communication with the combustion chamber for conveying combustion products from the combustion chamber. A second pipe member having a diameter larger than the first pipe member is disposed concentrically around the first pipe member. The first and second pipe members define an annular space therebetween forming an air intake duct. A combustion air duct extends between and is in fluid communication with the air intake duct and the combustion chamber for supplying combustion air to the combustion chamber. The exhaust pipe and fresh air pipe are respectively attached to the first and second pipe members and can be selectively oriented to extend away from the fireplace in a substantially vertical or horizontal direction.
