A gas burner comprising: a) a source of primary air under pressure; b) an elongate, generally cylindrical sheet metal body, having an inlet end, a closed distal end and a tubular segment extending between said ends; c) said distal end defining a mounting flange; d) said inlet end being formed to define a gas orifice holder, said holder mounting a gas orifice element; e) said inlet end further formed to define at least one primary air opening arranged to admit primary air from said source into said tubular segment; e) a bluff body located downstream from said gas orifice element and positioned such that gas emitted by said orifice flows along a flow path and impinges on said bluff body, said bluff body formed at least partially by a one dimple formed near said inlet end that projects into said flow path, a center point of said dimple being located downstream of said orifice element; and, f) a series of flame ports defined in said tubular segment and arranged to create a desired, predetermined flame pattern.
