Empire Comfort Systems Aspen Wood Firebox, 60" Opening

The Empire Aspen WB60FB0F opens at 60 inches wide by 38 inches tall — a scale that commands attention in any room it anchors. That isn't marketing math; it's the verified specification behind its standing as the largest UL-certified wood-burning firebox in its category, a distinction that matters when a project demands both genuine presence and documented safety compliance.

The firebox burns solid wood and processed solid fuel firelogs, and the clean, seamless exterior design means there's no visible smoke shelf interrupting the sightlines. The air control is hidden, so the hardware stays out of the aesthetic conversation. When you want a fireplace that looks like an architectural detail rather than an appliance, those refinements add up.

Liner customization is where the Aspen lets you genuinely tailor the interior to the room around it. Choose from firebrick, soapstone, or smooth concrete panels in a range of colors — each brings a different character to the firebox interior, from the traditional warmth of firebrick to the cooler, more contemporary feel of smooth concrete.

Installation flexibility is a practical strength here. The Aspen can be set directly on a wood floor, supported by included attic insulation shields for proper clearance above. It can be installed in sleeping rooms as well — a specification not every wood-burning firebox can claim. Note that it is not approved for manufactured housing.

Combustion air is handled through two outside air kits (model WBOAK, sold separately), each running up to 20 feet of 4-inch duct. Both kits are required — this isn't optional, it's part of the installation spec. If your project also calls for a gas log set down the road, the Aspen is compatible with one, provided the installation meets National Fuel Gas Code provisions at the time of conversion.

At this scale and with this level of certification, the WB60FB0F is a serious architectural fireplace for serious projects. The outside air kits are the one add-to-cart reminder before you finalize your order.
