The invention is a gas-fired burner for a fireplace, including an upper burner comprised of an upper tubular gas pipe and a lower burner comprised of a lower tubular gas pipe. The upper and lower tubular gas pipes meet at a junction, where gas to the lower tubular gas pipe is fed through the upper tubular gas pipe. Each of the tubular gas pipes has downwardly-facing, in-line orifices along their lengths. The improvement comprises a metallic strip having a width approximately equal to the inner diameter of the lower tubular gas pipe. This metallic strip is secured at its lateral ends to the interior of the lower pipe, and extends from a point adjacent the junction to a point beyond approximately the first twenty-five to thirty-three percent (25-33%) of the in-line orifices in the lower tubular gas pipe.

In a gas-fired burner for a fireplace, an upper burner comprised of an upper tubular gas pipe and a lower burner comprised of a lower tubular gas pipe, said upper and lower tubular gas pipes meeting at a junction, wherein gas to said lower tubular gas pipe is fed through said upper tubular gas pipe, and wherein each of said tubular gas pipes has downwardly-facing, in-line orifices along their lengths, the improvement comprising a metallic strip having a width approximately equal to the inner diameter of said lower tubular gas pipe, said metallic strip secured at its ends across its width to the interior of said lower pipe, and extending from a point adjacent said junction to a point beyond approximately the first twenty-five to thirty-three percent (25-33%) of said in-line orifices in said lower tubular gas pipe, said metallic strip thereby causing a substantial portion of said gas to said lower tubular gas pipe to avoid said first 25-33% of said in-line orifices.
