Do away with the need for gas lines or electrical wires and opt for a clean burning flame with the 78.5" Wide One-Sided Ethanol Burning Firebox. Constructed of solid grade 304 polished stainless steel, built with 3 mm thick double wall construction, and insulated with a patented rock wool insulation, the 39.5" Wide Double-Sided Ethanol Burning Firebox is fire rated so that no clearance is required between the firebox and construction materials such as sheet rock and wood framing. It can be built flush to the wall so you may enjoy more space on the floor.
