The Buck Stove ZCBB / NV ZCBB Vent-Free Firebox Enclosure is a 36 inch, zero-clearance, universal firebox system designed for use with listed vent-free natural gas log sets. Engineered for flexible installation, this firebox enclosure allows homeowners and builders to enjoy the look of a traditional fireplace without the need for a chimney or venting.

Built by Buck Stove in North Carolina, the ZCBB is approved for gas-fired unvented decorative room heaters up to 40,000 BTU, making it ideal for residential homes, manufactured homes (where permitted), remodels, and new construction projects. Its zero-clearance design allows installation directly against combustible framing, opening the door to custom surrounds, mantels, and finishing options such as stone, brick, or tile.

The ZCBB firebox enclosure includes factory-installed safety screens, a canopy, and heavy-duty steel construction. Optional accessories such as a flush mount mantel, wooden surround, and optional blower kit allow you to tailor the final installation to your space and heating needs.

If you’re looking for a vent-free natural gas fireplace solution that offers installation flexibility, classic aesthetics, and trusted American manufacturing, the Buck Stove ZCBB is a proven, contractor-approved choice.
