Abstract
An improved flue pipe for placement in the flue associated with an interior fireplace having a stove mounted therein. The flue pipe extends through the flue and has a spark arrestor mounted on its upper end. The lower end of the flue pipe has means for connecting it to the combustion gas outlet of the stove mounted in the fireplace. The flue pipe has a number of interconnected sections and several of the sections are of shapes permitting the flue pipe to extend through the damper region of the flue notwithstanding the reduced cross-sectional area of the damper region.
