Recommended Accessories


Choose the EcoSmart Flex Single Sided Bioethanol Firebox for a traditional fire with flexible, easy installation without emissions or mess. EcoSmart Flex Firebox inserts are made with a transparent toughened glass windscreen for protection without obstructing the view.

Adding a decorative option installs a glass separator creating a cubby to add non-combustible logs, stones, or other fire media. Choose Decorative Box Left, Decorative Box Right, 2 Decorative Boxes, or All Flame to enjoy a full fire experience.

The stainless-steel bioethanol burners within are designed to be used with eNRG bioethanol fluid for cleaner burning and efficiency. Ecosmart's burners are completely self-contained with no need for tanks or utility lines. Clean burning bioethanol means that your firebox won't produce any soot, ash, or harmful emissions. Designed for ease of use and safety, Ecosmart burners feature clear safety features allowing for easy flame regulation and maintenance.

The concept behind the Flex Series firebox inserts from Ecosmart is defined by the title: Flexible Installations. The wide variety of designs, styles and sizes, minor assembly requirements, zero clearance construction, combined with the clean burning bioethanol fuel source provides endless design flexibility and installation freedom to homeowners, designers, architects and builders alike.
