Empire Blackburn 54" Wood Burning Firebox
The Empire Blackburn 54" is an indoor wood burning fireplace firebox, listed to UL 127, with a 54" wide by 34" high opening.
Model number WB5412FB0F comes with a firescreen, grate and attic insulation shield, and vents through Empire's 12" chimney system. It needs a refractory brick liner, a non-combustible hearth extension, the chimney sections and a termination cap, all listed below.
The Blackburn 54": A Large Indoor Wood Burning Firebox
The firebox needs at least 1 1/2" of air space to combustibles at the back and sides, with the opening at least 24" from a sidewall, and a mantel can sit 18" or more above the opening, up to 10" deep. The hearth extension is built as the manual shows for a flush or raised firebox. It may be installed in a bedroom, and it is not approved for manufactured housing.
The chimney uses only the Empire 12" components listed in the manual, at least 20 ft tall (22 ft with two offsets) and no more than 90 ft, with a firestop wherever it passes through a ceiling or floor. For better draft, it goes inside the warm, insulated part of the house, away from doors, walkways and air returns.
