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 32SS means the entire viewing area is dedicated to the eye-catching flame, creating a harmonious blend of traditional style and contemporary design. The XL500 burner, the 'baby' of the XL Series, delivers a stunning, long-lasting linear flame. It may be compact in size, but with a 1.3 gallons capacity, this ethanol burner can heat up to 431ft2. Efficiency is a key feature of this burner, delivering up to 13 hours of heat generating flame off a single refill.
