From the curve of each log to the height of the stack, your White Mountain Hearth Log Set is crafted to complement the burner pattern and produce a lifelike fire. Flames dance and swirl to captivate your imagination and warm your soul. Complete the illusion with one of Empire's optional Ember Bed Kits and Platinum Glowing Embers. Unlike a wood fire, your White Mountain Hearth vent - free logs create a consistent, controlled heat - without dangerous flare - ups or chilling die - downs. Empire's vent-free gas logs warm your room quickly and efficiently, while using about half the energy of a traditional vented gas log. For people who have grown tired of hauling in logs, hauling out ash, and living with uneven heating, White Mountain Hearth logs are the perfect replacement in a traditional fireplace. White Mountain Hearth vented vent-free burners do not require a flue. Originally designed for use in vent-free fireplaces, these burners work equally well in traditional flue-vented applications. They can be ordered for use with natural gas or LP. Harmony Burner serves as the basis for the premium line of meaty, massive log sets - the Wildwood and Canyon. Special baffles within the burner induce movement in the flow of gas to accentuate the naturally flickering flames.24 Log Set 5-Piece Burner BTU input 38,000 Fits Empire Firebox: Deluxe VFD-36, Premium VFP-36, Select VFS-36.
