ABSTRACT:
A coupling assembly for connecting a flue gas pipe with an inlet duct of a chimney includes a tubular compensator having a first end secured to the flue gas pipe and a second end oriented towards the inlet duct and having a radially projecting flange. The chimney part which surrounds the inlet duct has a planar face provided with a groove spacedly surrounding the inlet duct. An endless bead forming part of the flange projects from the frontal face thereof and is received in the groove. There are further provided screw connections anchored in the chimney externally of the compensator flange and pressing members operatively connected to the screw connections and being pressed thereby against the flange to clamp the flange against the planar chimney face. The pressing members extend over and across the bead. A rubber-elastic adhesive layer is situated between the flange and the planar face of the chimney and is glued to the flange, the bead, the planar face and the groove.
