While in the foregoing is shown and described a preferred embodiment of my inven- 5 tion, I do not wish to be limited to the specific features of construction, combination, and arrangement of parts, as it is recognized that many alterations such as adapting the device for use in cooking stoves may be resorted to without departing from the spirit and scope of the invention as defined in the appended claim.

I claim: The combination with a liquid fuel stove having a burner, a housing surrounding the burner and an annular seat on the housing, ofa chimney comprising a cylinder of transparent. non corrosive material seated on the annular seat and completely encircling the 2( burner, a metallic cylinder supported on the upper end of the first mentioned cylinder, 7 said metallic cylinder having a notch in its lower edge, a lug adjacent the upper end of the non-corrosive cylinder for engaging in the 5 notch to prevent rotation of one cylinder relative to the other, aplate closing the upper end of the metallic cylinder and tie rods extending between the housing and the plate for holding the separate parts of the chimney tom gether and in position on the stove.
