Description

Featuring a front-facing view of vivid flames, this fireplace becomes an impressive design focal point for both indoor and outdoor spaces.
Fueled by clean-burning e-NRG bioethanol, it eliminates the need for gas lines, vents, or electrical connections—providing freedom in installation and maintenance. The zero-clearance design allows flexible placement in wood or metal framing, making it ideal for modern architecture and renovation projects.
Constructed with durable zinc-sealed steel and finished in high-temperature black coating, the Flex 50SS ensures long-lasting resistance to rust and wear. Its stainless steel burner, integrated windscreen, and black glass charcoal enhance safety and style, while the left-side decorative box adds balance and sophistication to the overall design.
Enjoy an alluring flame from any angle you look at it:
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 50SS.BXL comes with a Decorative Box on the left-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.
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.
