Connection line for smoke-proof connection of floor-furnace to chimney, has connection bush including heat-resisting pipe and pushed through inner pipe in installed position, and direct connection with chimney tube produced

摘要

The line (10) has a connection pipe (11) including ends formed such that one end is pushed into an exhaust stack from an individual furnace and another end is pushed into a radial intermediate space between an inner pipe (12a) and an outer pipe (12b) of a wall lining (12). A connection bush (13) includes a heat-resisting pipe with an outer diameter smaller than an interior inner diameter of the inner pipe, and an axial length larger than axial length of the inner pipe. The bush is pushed through the inner pipe in an installed position, and a direct connection with a chimney tube is produced. The thermal insulation layer includes rock wool, glass wool, mineral fleece, mat or ring of mineral material, and non-combustible sheath with mineral granulates.
