Upgrading your hearth from a basic metal firebox to an artistic stonework creation, this unit comes ready for assembly—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.

Configured for natural draft application, this unit draws combustion air from the inside of your home, then exhausting byproducts through a roof vent or chimney. This firebox arrives with a fuel line knock-out that can be placed on either side of the firebox and a set of 30” gas logs—no on-sight drilling is required. These logs are custom made for this firebox and are constructed of refractory ceramics with steel rod reinforcements. These logs will radiate heat while in operation and after the burner has been turned off. For all specific measurements and included pieces, 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.
