Upgrading your hearth from a basic metal firebox to an artistic stonework creation, this unit comes ready for assembly indoors or out—and because it weighs less than normal masonry fireplaces, it can be installed on any floor of the house without the need for extraneous reinforcement. The base is pre-drilled to make rebar installation easy, and the included 50 lb. bucket of dry mortar provides everything you need to complete the project. With proper care, the entire firebox can be completed in less than two hours, rather than a traditional installation that can last up to three weeks.
Although this firebox can accommodate glass doors, it is not recommended that they remain closed while a fire is burning. Spark arrestors and chimney caps are also great options to provide additional downdraft and fire safety. The unit arrives designed for wood burning, with a fuel line knock-out that can be placed on either side of the firebox. For those who prefer to keep their fireplace wood burning only, the knock-out is easily mortared off with the included concrete plug—for those who are after the convenience of a propane or natural gas fuel line, no on-sight drilling will be required. For all specific measurements, please refer to the attached PDF charts.
Please note that a metal base is required in order to burn a masonry fireplace on wood flooring. All pieces and components are proudly manufactured and distributed in the United States of America, complying with UL 127 and UL 103 chimney standards. This firebox is ICC-ES listed.
