More than a flicker of design inspiration. The Flex Firebox - Single Sided with Decorative Sides is an EcoSmart design that invites the classic ambiance of a fireplace without the bother of soot and ash or the need for vents and chimney flues. Completely self-contained and fueled by smokeless Bioethanol, fireboxes are easily installed by contractors and builders and ready to enjoy right away. A toughened Glass front offers a clear view of the flames. Customize the fire feature with the decorative box placed on one side or both sides. Fill the box with your choice of a noncombustible log set or other nonflammable accessory for a charming fireside finish.
