ABSTRACT:
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.
