Complete with authentic wood tones and deep charred wood patterns, it's easy to see how the CUSTOM SERIES elaborately hand-crafted log stack and radiant ember bed could be mistaken for a real wood burning fire. Gas log control assembly is tucked away out of view. A brightly burning ember presentation in a vented gas log set can only be achieved through industry-leading design and precise fuel combustion. 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.
