With two open sides, Flex Double Sided fireplace insert creates the perfect room divider. The see-through design provides unobstructed views of the flickering flame from the front and the back, infusing warmth and ambiance into two adjacent rooms.
The Flex 86DB.BX2 includes a design that features Decorative Boxes on either side of the firebox. This 2 Box-design boasts an attractive visual symmetry while the glass panels that divide the Decorative Boxes and the Firebox create an uninterrupted, streamlined look.
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.
