Yellow flame gas fireplace burner assembly

Abstract

A gas fireplace burner assembly which produces a yellow flame and simulates the appearance and pattern of the yellow flames produced by a natural wood log fire includes a log grate for supporting a plurality of artificial logs. The log grate is formed with a stepped configuration and has a back wall and opposite side walls, each of which has an opening formed through its thickness to allow secondary air to pass therethrough and into an interior space defined by the walls of the log grate. The log grate also includes a slotted grate front member. At least a front and rear artificial log is supported on the log grate. A burner tube is also supported by the log grate and has front and rear portions which are disposed in parallel. A front flame deflector is interposed between and spaced apart from the grate front member and the front portion of the burner tube and defines first and second channels for secondary air to flow through. Artificial ember material is situated adjacent to the front burner tube portion and is further situated so as to be adapted to come in contact with flames emanating from the front burner tube portion. A rear flame deflector is at least partially superposed over the rear burner tube and has a plurality of flame openings formed in it. A gas control assembly controls the passage of gas through the burner tube, and includes a gas valve which communicates with the burner tube and which can be coupled to a source of gas.
