Specifically designed for a single room application, the Flex Single Sided Fireplace Insert features one open side, enabling the flame to be viewed from the front. The bioethanol, true zero-clearance fireplace can be used to create a striking addition to a feature wall, integrated within cabinetry or a fireplace setting - whether in a residential dining room, indoor or outdoor living area, or commercial spaces. The clean lines and 'all flame' configuration of the Flex 104SS means the entire viewing area is dedicated to the eye-catching flame, creating a harmonious blend of traditional style and contemporary design. One of the longest flames available in the Flex Series is created by using 2 of our ever-popular XL 900 Burners. With an overall heating capacity of 1399ft2 this appliance is best suited to large open spaces - think hotel lobby, large open plan restaurants. Each burner holds 2.6 gallons of fuel, and can deliver a stunning flame for up to 14 hours.
