Abstract
Apparatus for cooperation with an associated flue having a first axis extending away from a point proximate to an associated combustion chamber which includes a funnel shaped member having first and second ends. The second end is larger than the first end. A damper is disposed in the associated flue which has a generally central bore. The damper is mounted in the associated flue for rotation about a second axis which is generally perpendicular to the first axis and the funnel shaped member is mounted with the first end higher than the second end and with the second end extending into the damper. The mounting for the damper may comprise at least one rod shaped member extending through at least one wall of the associated flue. The mounting for the funnel shaped member may comprise a plurality of elongated members extending radially from the funnel shaped member to the associated flue. In another form of the invention a first duct is disposed within a second duct which is in fluid communication with an associated flue. The first duct may be rectangular in cross section and generally planar members may be selectively pivoted to restrict flow intermediate the first and second ducts. The…
