30、ts, including methods of test, for precast concrete flue liners and fittings with or without insulation for the construction of multi-wall chimneys. This document does not cover: high positive pressure (H) designated products; products designated wet (W) in conjunction with corrosion class 3. This d
31、ocument also applies to storey-height and flue liners reinforced only for handling. NOTE 1 Any reference to the term flue liners implies both flue liners and their fittings, except where otherwise indicated.
