The HearthStone Gemini 48, 60, or 72 gas fireplace.

One of the most important distinction of the Gemini fireplaces is that they can be vented down, through a lower floor and out a side wall with our exclusive, optional, power vent, or vented vertically through the roof, or up and through a side wall.
