An artificial log set including a fire grate having a base and an upper section pivotally connected to the base, pivotable between a lowered burning position and a raised access position. A fuel reservoir is supported by the base. A burner head is attached to the upper section so as to be positioned
An artificial log set including a fire grate having a base and an upper section pivotally connected to the base, pivotable between a lowered burning position and a raised access position. A fuel reservoir is supported by the base. A burner head is attached to the upper section so as to be positioned directly over the fuel reservoir when the upper section is in its lowered burning position, and so as to allow access to the fuel reservoir when the upper section is in its raised access position.

What is claimed is: 1. An artificial log set comprising: a fire grate including a base and an upper section pivotally connected to said base, said upper section pivotable between a lowered burning position and a raised access position; a fuel reservoir supported by said base; a burner head attached
What is claimed is: 1. An artificial log set comprising: a fire grate including a base and an upper section pivotally connected to said base, said upper section pivotable between a lowered burning position and a raised access position; a fuel reservoir supported by said base; a burner head attached to said upper section so as to be positioned directly over said fuel reservoir when said upper section is in its lowered burning position, and so as to allow access to said fuel reservoir when said upper section is in its raised access position; said burner head being rectangular in configuration and having a burner head interior volume in communication with said fuel reservoir when said upper section is in its lowered burning position, said burner head interior volume being defined by a pair of burner head end walls, a pair of opposed burner head main walls, and a burner head top; said burner head top having a combustion air intake slotted opening and a flame outlet slotted opening separated by a top partial wall extending between said burner head end walls; and said burner head including an internal baffle extending horizontally between said burner head end walls and downwardly from said top partial wall towards said fuel reservoir, said internal baffle dividing said interior volume into a combustion air zone in direct communication with said combustion air intake slotted opening and a flame zone in direct communication with said flame outlet slotted opening. 2. The artificial log set of claim 1, wherein said internal baffle has a lower edge located so as to expose a first region of said fuel reservoir portion primarily to the combustion air zone and a second region of said fuel reservoir portion primarily to the flame zone, the second region being greater in area than the first region. 3. A burner for liquid or gelled-liquid fuel, comprising: a fuel reservoir portion and a burner head portion over said fuel reservoir portion; at least said burner head portion being rectangular in configuration, and having a burner head interior volume above and in communication with said fuel reservoir portion, said burner head interior volume being defined by a pair of burner head end walls, a pair of opposed burner head main walls, and a burner head top; said burner head top having a combustion air intake slotted opening and a flame outlet slotted opening separated by a top partial wall extending between said burner head end walls; and an internal baffle within said burner head extending horizontally between said burner head end walls and downwardly from said top partial wall towards said fuel reservoir portion, said internal baffle dividing said interior volume into a combustion air zone in direct communication with said combustion air intake slotted opening and a flame zone in direct communication with said flame outlet slotted opening. 4. The burner of claim 3, wherein said burner head portion is elongated, with said burner head main walls having a greater lateral extent than said burner head end walls. 5. The burner of claim 3, wherein said combustion air intake slotted opening is immediately adjacent one of said burner head main walls and said flame outlet slotted opening is immediately adjacent the other of said burner head main walls. 6. The burner of claim 5, wherein said slotted openings extend between said burner head end walls. 7. The burner of claim 3, wherein said flame air outlet slotted opening is larger in area than said combustion air intake slotted opening. 8. The burner of claim 7, wherein the ratio of the area of said flame outlet slotted opening to the area of said combustion air intake slotted opening is within the range 1.5:1 to 3:1, inclusive. 9. The burner of claim 8, wherein the ratio of the area of said flame outlet slotted opening to the area of said combustion air intake slotted opening is approximately 2:1. 10. The burner of claim 3, wherein said internal baffle has a lower edge located so as to expose a first region of said fuel reservoir portion primarily to the combustion air zone and a second region of said fuel reservoir portion primarily to the flame zone, the second region being greater in area than the first region. 11. The burner of claim 10, wherein the ratio of the area of the second region to the area of the first region is approximately 3:1. 12. The burner of claim 10, wherein said internal baffle extends downwardly from an edge of said top partial wall adjacent said flame outlet slotted opening. 13. The burner of claim 12, wherein said internal baffle forms an acute angle with said top partial wall such that the ratio of the area of the second region to the area of the first region is greater than would be the case if the internal baffle extended vertically downwardly at an angle of 90�� with reference to said top partial wall. 14. The burner of claim 3, which further comprises an adjustable damper for selectively reducing the effective size of said flame outlet slotted opening for flame height adjustment. 15. The burner of claim 13, which further comprises an adjustable damper for selectively reducing the effective size of said flame outlet slotted opening in cooperation with said internal baffle for flame height adjustment, said adjustable damper in turn comprising a plate pivotally connected to one of said burner head main walls adjacent said flame outlet slotted opening opposite said internal baffle. 16. The burner of claim 15, which further comprises a linkage connected to said damper to facilitate adjustment. 17. The burner of claim 3, wherein said burner head portion is separable from said fuel reservoir portion so as to provide access to said fuel reservoir portion. 18. The burner of claim 17, which further comprises a removable snuffer plate configured to cover said fuel reservoir portion for snuffing a fire.
