Double-sided, the 64.25" Wide Double-Sided Ethanol Burning Firebox tenders a long flame of over 43” – an ideal solution for commercial and grand residential settings. It offers flames that may reach up to 11" high and produces a linear fire display 43.5" long. 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 64.25" 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.
