Forge Outdoor Coal Furnace Series

The FireStar® combustion controller monitors all functions of the furnace and automatically adds air when and where it is needed (over or under the fire, or both) for a cleaner and more efficient burn. Loading coal is easy with the large firebox door. Ergonomically designed, the firebox door is insulated and easy to open and close. Heavy-duty shaker grate, conveniently operated by handle on side of the furnace, allows ash to fall below into the ash collection area. Ash removal is easy.
