About This Product

Redefine Modern Elegance with the Earthcore Xcelux Linear Fireplace

Make a bold architectural statement with the Xcelux Linear Series, where advanced technology meets refined design. This fireplace delivers stunning flame presentation and flexibility without compromise, no need to choose between size, performance, or aesthetics. Equipped with the X-Ventiso Meridian Fan & Control System and a remote-controlled electronic ignition, the Xcelux offers a seamless, ultra-quiet, and integrated fireplace experience for contemporary living. 

Choose from multiple sizes (48", 60", 72", 96", 120") to suit your space. Its Isoflames XL Linear Burner delivers up to 200,000 BTUs of power, using a patented interlocking design that creates a flush, low-profile foundation for exceptional flame clarity.

For added versatility, the X-Ventiso mechanical venting system is available in three fan sizes with adaptive controllers to maintain proper draft — ideal for various hearth configurations and fuel types. Finish it your way with five fireglass color options or lava pebbles to elevate your flames into a custom visual centerpiece.
