Feed and burner control system

An improved assembly for creating a fire display from a liquid fuel comprising a burner tray and a non-combustible structure:

• one or more fuel sources containing a liquid fuel, said fuel sources not located within the fire display structure, connected to one or more burner trays by one or more tubular flow conduits, said flow conduits providing fluid flow channels to transfer the liquid fuel from said one or more fuel sources to said one or more burner trays in the fire display assembly, the one or more burner trays within or adjacent the non-combustible structure or containing one or more non-combustible structures, said liquid fuel when ignited providing a flame above or adjacent exposed surfaces of the one or more non-combustible structures, the improvement comprising:
• the one or more liquid fuel sources being replaceable and located at a distance from the flame to allow replacing the liquid fuel source while a flame is present while preventing ignition of the liquid fuel at the fuel source, the one or more conduits having a flow controlling mechanism located therein to control the transfer of the liquid fuel from the one or more replaceable fuel sources to the one or more burner trays through the one or more of the tubular conduits, said flow controlling mechanism configured to vary the rate of liquid fuel flowing there-through which, in turn, increases or reduces the amount of liquid fuel in the burner tray causing a delayed change in the size of the flame emanating from the non-combustible structures or adjacent the non-combustible structures to be increased or reduced over an extended period of time without extinguishing the flame, and
• further including a flame sensor, said flame sensor operatively connected to the flow controlling mechanism so as to provide a controlled liquid fuel feed in response to changes in height of said flame.
