  • Ignis C-Shaped Built-in 3-Sided Ethanol Firebox, Stainless Steel or Black

    Ignis Authorized Retailer

    Ignis C-Shaped Firebox is a modern, clean-burning, and ventless 3-sided ethanol fireplace ideal for installation in a custom build or as an insert in an existing masonry fireplace. Made of corrosion-resistant, solid grade stainless steel, available in 4 sizes and 2 colors, stainless steel or black, this firebox is great for any residential or commercial setting.

    This 3-sided firebox is built with double-wall construction, each of 3mm thickness, and further insulated with a patented rock wool insulation, making this ethanol firebox heat resistant. Thus, it is one of the safest ethanol fireboxes available today for custom projects. 

    This heavy-duty, zero clearance fireplace was designed for easy installation. Using the surrounding flange, simply build into the wall, existing hearth, or custom surround. Clean-burning ethanol fuel does not need special ventilation. 

    Available in four sizes - 36", 48", 60", and 72" wide, install this 3-sided firebox in a new build where you can enjoy the fiery view from three sides. Or, upgrade your existing fireplace to a smoke-free and maintenance-free unit.

              Recommended Fuel:

              Ethanol fuel burns cleanly and does not produce the soot, smoke, or mess that is normally associated with a wood-burning fireplace. This ethanol fireplace fuel is made from 100% alcohol without the use of any oil at all. Ethanol is produced from renewable agriculture products, like barley, grains, sunflowers, corn, wheat, and potatoes, and manufactured in an earth-friendly process that does not harm the environment.
