Abstract
A gas burner assembly is provided which can be used in an unvented gas-fired fireplace and which closely approximates the look of a wood-fired fireplace. The gas burner assembly has a gas distribution chamber with a horizontal base, a vertical backwall, a top wall, a pair of opposing vertical side walls and a front wall. The front wall is a continuous surface having a vertical forward section and a substantially concave rear section. A small number of ports are disposed within the front wall to generate a small, evenly-distributed flame pattern across the front wall. A flame deflector plate located forward of the front wall to direct flame from the lower portion of the front wall upwardly. A large number of ports are disposed within the top wall to generate a large vertical flame pattern at the top wall. The ports in the front wall and in the top wall are disposed so that flames from the burner assembly do not substantially impinge upon ceramic faux logs affixed to a log rack above the gas distribution chamber. The gas burner assembly burns extremely efficiently.
