Sliding compensators provide holding side-bars in axial direction during chimney assemblage. Gas-escape channel is formed in element-wise manner of multilayer panels produced of polyolefin. When connected in tubular sections panels create polyhedral side surface provided with support flanges arranged along the full perimeter thereof for sections connection one to another with side-bars forming. Support flanges have L-shaped extensions forming funnels in which lower part of another section is inserted. Support flange positions in lower section parts are adjusted along L-shaped extension height.
