Empire Comfort Systems 60" Wood Burning Linear Firebox

The framing dimensions tell the story first: at 73⅝ inches wide and 64¼ inches tall, this firebox is built to anchor a wall, not decorate a corner. The 60-inch glass opening — 60 inches wide by 24 inches tall — delivers the low, wide, cinematic flame profile that linear fireplaces are known for, and Empire backs the whole assembly with UL certification so your builder and insurer can rest easy.

Despite its scale, the clearance requirements are remarkably tight: just 1½ inches to the back wall and 1½ inches to either sidewall. That kind of dimensional efficiency matters when you're working around cabinetry, built-ins, or a media wall where every inch of depth is negotiated. The 30½-inch framing depth is worth confirming early with your contractor, and installation requires a 12-inch chimney vent system.

Inside the firebox, seven liner configurations let you dial in the aesthetic from rustic to refined. Firebrick liners come in soapstone, buff, and red. Concrete liners are available in white, gray, black, and mocha — a range that covers everything from Scandinavian minimalism to warm industrial. This is one of the more genuinely useful customization menus in the category, because the liner color has an outsized effect on how flame and embers read against the backdrop.

Practical details worth noting: the unit can be installed directly on a wood floor, attic insulation shields are included, and a 12x2-inch inner vent handles airflow. For households that want the option to switch fuels later, the firebox is compatible with an optional 36-inch gas burner conversion, as well as certified gas log sets or a gas lighter — making it one of the more adaptable wood-primary fireboxes available at this size.

If the linear format isn't the right fit for your space, this same firebox is also offered in a traditional style (WB60FB0F). But for rooms where the architecture calls for horizontal drama and a clean sightline to the flame, the linear configuration is the one worth specifying.
