The PRO SERIES TRIPLE-FLAME boasts a triple burner and glowing ember bed at its base to achieve the look of a real wood fire. Flickering embers are achieved through the use of two unique technologies. The Triple-Flame burner offers the distinctive feature of an additional row of flames behind the logs. The result is a striking appearance with a very deep flame pattern. The Superior unique, clean burning design provides 99% heating efficiency, allowing you to operate the logs vent-free with the fireplace damper closed. With no venting required, there is no heat loss up the chimney. Plus heating with Superior gas logs means you'll never again be left in the cold with wet logs or without heat during a power outage.
