ABSTRACT:
A burner having an elongate, generally tubular sheet metal body having an inlet end, a closed distal end and a tubular segment extending between the ends. The inlet end is formed to define a gas orifice holder which is adapted to mount a gas orifice element. The inlet end is further formed to define at least one primary air opening arranged to admit primary air from a source of primary air. Rows of flame ports are defined in the tubular segment and are arranged to create a desired predetermined flame pattern. When used as a fireplace burner the flame ports may be slot-like in construction and include tabs which determine the effective size of the ports. In a fireplace application, flame ports located below a crossover log, are eliminated and/or formed of reduced size, thus providing a flame of lower height and/or less intensity, thus substantially eliminating sooting. When used as a premix-type burner, a source of primary air under pressure is delivered to the inlet end of the burner and compensates for the restriction posed by the bluff structure, resulting in a blue flame.
