Empire Blackburn 36" Zero-Clearance Wood Firebox

The Empire Blackburn wood firebox ships with a smooth, no-brick interior finish — a clean slate that lets you choose exactly how the finished fireplace looks once it's framed in. The 36" W x 30" H viewing area delivers a generous, open flame presentation, while the 44" x 30" framing opening gives your builder real flexibility in designing the surround. Construction is heavy-duty steel throughout, built to handle real fires with real wood. The 3/4" bar stock grate is no afterthought — it's the kind of hardware that holds up when you're loading 24-inch logs and actually using the fireplace the way a wood-burning fireplace is meant to be used. Zero-clearance design means this firebox can be installed directly against combustible framing without additional standoffs or elaborate heat shields, which simplifies the build and expands where it can realistically go in a home. An easy-access air control lets you manage combustion without guesswork, and the included pull screen handles sparks cleanly. When it comes to finishing the interior, the Blackburn is compatible with an impressive range of optional liner systems: traditional brick, herringbone patterns in natural concrete, gray, white, mocha, and black, or a smooth surface refractory if you want a more contemporary look. Whether you want the warmth of a classic masonry aesthetic or something more refined and architectural, the liner options give you genuine range — not just a single color choice with a different name. This firebox can also be used with or without a gas log set, so if you ever want to add a gas ignition option down the line, the firebox doesn't close that door. That said, it's a wood-burning unit at heart, sized and built for those who want genuine wood fires — the smell, the sound, and the 24-inch logs to prove it. At this scale and this level of construction, the Blackburn is a serious firebox for a serious fireplace project. It earns its place in the budget before the first fire is ever lit. 36" W x 30" H viewing area for a commanding flame presentation 44" x 30" framing opening for flexible surround design Zero-clearance construction — installs against combustible framing Heavy-duty steel construction throughout 3/4" bar stock grate handles logs up to 24 inches Ships with smooth, no-brick interior finish as standard Compatible with optional brick, herringbone, and smooth refractory liner systems Herringbone liners available in natural concrete, gray, white, mocha, and black Includes pull screen and easy-access air control Compatible for use with or without a gas log set Fuel Type Wood Size 36 inch Viewing Area 36" W x 30" H Framing Opening 44" x 30" Maximum Log Size Up to 24 inch Construction Heavy-duty steel Grate Heavy-duty 3/4" bar stock grate Design Zero-clearance Interior Finish Smooth, no-brick (as shipped)
