White Mountain Hearth gives you realism combined with peak heat in their 18 inch Ponderosa Vent Free Refractory Log. The curves of each driftwood log along with the height of the stack makes this vent free log set from Empire complement the burner pattern for a lifelike fire. Ponderosa logs are modeled after actual logs found in nature. The popular Slope Glaze Burners raise the standard for dancing flames. Internal ceramic beads tumble the gas to create especially genuine flame movement. Your White Mountain Hearth Vent-Free log set creates a consistent, controlled heat – without hazardous flare-ups or chilling die-downs. These 18 inch vent free cement gas logs warm up your room in a snap, while using about half the energy of a vented gas log. You can choose from a manual or remote controlled set. The remote choices are on/off with flame height adjustment or thermostatically controlled.
