Description
The Bio Flame 84" Firebox DS (72 Manual) is a wide ventless bioethanol fireplace insert built for homeowners who want a real flame in a large living room, great room, or media wall without the cost and mess of a wood-burning or gas chimney setup. With a 72" burner and 84" overall width, it is sized for expansive walls and open-concept spaces where a standard-size insert would look undersized. It installs into existing fireplace openings or custom-built surrounds, giving you the visual of a linear fireplace while delivering genuine heat output.
