Abstract
This gas burner system provides an asymmetrical flame pattern together with the presence of glowing embers around and beneath non-combustible logs, closely resembling the overall appearance of a natural wood fire in a fireplace. The burner system has a plurality of gas burner pipes arranged in a fan-out pattern on a log mounting plate to provide gas throughout the logs arranged over the plate. Air supply openings are formed at selected areas in the mounting plate to permit fresh air to pass only therethrough from below the mounting plate to the fire. Air deflectors are located adjacent to the openings and lava rock and/or mineral fiber pieces are placed below the logs over the gas burner pipes to disperse the combustible gas throughout the log arrangement. The provision of openings and deflectors create air currents flowing over the surfaces of the logs to prevent the flames from imposing on the log surfaces for reducing the formation of carbon deposits and carbon monoxide gas.
