Empire Breckenridge 42-Inch Vent-Free Zero Clearance Firebox

The Empire Breckenridge VFD42FB0F is a 42-inch vent-free zero clearance firebox built for straightforward installation and long-term flexibility. Its outer casing side and back flanges are zero clearance to combustibles, which means your framing crew won't spend the afternoon doing math — the firebox goes in cleanly and confidently.

The flush face front style keeps sight lines unobstructed, giving you a clean canvas for whatever surround, liner, or door configuration your project calls for. Out of the box, the unit ships with a junction box and a standard matte black hood. If your non-combustible facing material runs thicker than one inch, extended hoods are available to accommodate the added depth — a small detail that prevents a big headache during finishing.

At a maximum of 40,000 BTU/H, this firebox has genuine heating muscle. Clearance requirements are straightforward: 6 inches minimum on sidewalls, 36 inches minimum at the front, and 42 inches minimum from the top of the hood to the ceiling. At 102 pounds, it's substantial without being unwieldy for an experienced installation crew.

Where this firebox earns its keep is in its compatibility range. It works with all certified vent-free fireplace burners and log sets — none of which are locked to a proprietary ecosystem. Liner options sold separately include Porcelain Reflective, Stainless Steel, Aged Brick, and Banded Brick, so the finished look can run anywhere from sleek and modern to classically rustic. Compatible door, louver, frame, and mantel accessories round out the accessory catalog.

Two optional add-ons are worth noting for comfort and air quality: the FBB5 Single Speed Blower improves heat distribution throughout the room, and the BVA1 Fresh Air Kit draws outside combustion air into the firebox — a smart inclusion in tightly built or well-insulated homes where indoor air management matters.

All specifications, clearances, and compatibility details shown here reflect verified product data. Burners, log sets, liners, blowers, fresh air kits, and decorative accessories are sold separately.
