A gas log set turns an existing fireplace into a gas fire. Hand-painted ceramic logs sit over a burner in the firebox, so the room keeps its original hearth while the fire lights from a match, a pilot or a remote.
Two kinds are listed here. Vented sets, such as Rugged Split Oak, White Birch, Rustic Oak Designer and Mountain Birch, burn in a working wood-burning fireplace with the damper open and are chosen mainly for the look of the flame. The vent-free Charred Frontier Oak burns without a flue and is limited by local rules and by the room it sits in. Either way, the set is matched to a specific burner, fuel and fireplace size, so measurements come first.
