The base of the table features a hidden chamber that holds a 20 pound LP gas tank and control knob for adjusting the heat output to your preference. A bag of lava rock coals are included which adds a pop of flare to the flame. The porcelain tile table-top is finished with a UV-resistant powder coating that seals and protects it from the outdoor elements. A square burner lid is included for an easy conversion into a full coffee table when the fire is not in use.
