Aluminum frames covered with concrete board are ready to be easily and quickly completed with your choice of stone or veneer. Simply place your READY-TO-FINISH (RTF) kit on site, connect to the gas supply, add stone or other veneer, and your fire feature is complete. Feature can be placed on both patios and decks - any stable flat surface will work for installation. Ready-to-Finish Kits come with a Fire Pit Vent Kit (FPVK), but they do not come pre-installed as placement and installation depends on veneer. Vents are to be installed by contractor on site.
