Beyond Real From the curve of each log to the height of the stack, your White Mountain Hearth Log Set complements the burner pattern for a lifelike fire. Complete the illusion with one of our optional Ember Bed Kits and Platinum Glowing Embers. Your White Mountain Hearth Vent-Free log set creates a consistent, controlled heat – without dangerous flare-ups or chilling die-downs. These gas logs warm your room quickly and efficiently, while using about half the energy of a vented gas log.
