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 Flex 104SS.BXR comes with a Decorative Box on the right-hand side. The design is fitted with a glass panel that divides the box and the Firebox and creates an attractive streamlined look. Instantly transform any wall into a feature, indoors or out, with a stylish, clean-lined Flex Firebox.
One of the longest flames available in the Flex Series is created by using 2 of our ever-popular XL900 burners. With an overall heating capacity of 120m2 this appliance is best suited to large open spaces – think hotel lobby, large open plan restaurants.
Each burner holds 9L of fuel, and can deliver a stunning flame for up to 13 hours.
