The Flex 104SS.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.

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 1292ft² 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.
