Dimplex’s Prism series (BLF5051, BLF7451, BLF3451) is the best-selling linear fireplace. And with good reason. Flickering with intensity in a full range of colors, the flame effect of Prism Series appliances illuminates the ember bed formed by diamond-like pieces of acrylic glass. What an effect! Equipped with a powerful, efficient forced-air heater, your fireplace will enhance the comfort and ambience of any space. Prism electric fireplaces are wonderfully versatile. They can be wall-mounted, directly connected, suspended or recessed. The Prism BLF5051 is 60 ^3/8 ” x 19 ^1/2 ” x 7 ^3/8 ” (WxDxH).
