Zusammenfassung: | A tubular chimney liner is supported within the outer tubular shell of a chimney structure by tensioning means connected between the liner and the shell for applying an upward force to the liner in excess of its weight, and tethering means connected to the liner adjacent to its bottom end for maintaining the bottom end of the liner in a substantially constant position. The liner is thus supported under longitudinal tension, and changes in length due to thermal changes are taken up at its upper end. |
