More Product Info
The Dual-Flame Series’ 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 vent-free gas logs means you’ll never again be left in the cold with wet logs or without heat during a power outage.
