The EcoSmart Flex Double Sided Bioethanol Firebox insert provides a crackling fire view from two sides without emissions or mess. Place it between a kitchen and family room or even a living room and outdoor patio! EcoSmart Flex Firebox inserts are made with a transparent toughened glass windscreen for protecting without obstructing the view. Adding a decorative side option installs a glass separator creating a cubby to add non-combustible logs, stones, or other fire media.

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.
