Designed for single room installation, the Left Corner Fireplace Insert features two open sides. The transparent glass on the left corner enables the flame to be viewed from the front and the left corner, providing interior designers, homeowners, architects and builders with the freedom to customise their fire solution to suit a floor plan. The Flex 158LC.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 3 of our ever-popular XL900 Burners. With an overall heating capacity of 1938ft2 this appliance is best suited to large open spaces - think hotel lobby, large open plan restaurants. Each burner holds 2.4 gallons of fuel, and can deliver a stunning flame for up to 13 hours.
