A fire display apparatus comprises a structural base plate supported in a horizontal attitude within a clay, or other fire resistant bowl. The base plate supports an annular burner tube on a outer, upwardly facing surface, the burner tube providing outwardly directed plural burner apertures adapted for directing flames in a peripheral, horizontal, outward direction. The base plate also supports a burner fence positioned in spaced-apart relationship with the burner apertures and adapted for directing the flames in an upward direction away from the outer face of the base plate. A rim fence ring is positioned outward of the burner fence and is adapted for reflecting heat inwardly. Burner gas is supplied to the space between the bowl interior and the underside of the base plate. Here, gas valves and a flame sensor provide automated flame monitoring and control.
