6.6. Example of clay flue liner.
The separation of the flue liner from the surrounding
concrete or masonry shall not exceed the wall thickness of
the flue liner. Where Seismic Reinforcing requires the
space between the flue liner and the chimney wall to be
grouted solid the flue shall be wrapped with ceramic fiber
paper capable of withstanding temperatures of 2100ºF to
prevent the flue liner from bonding to the chimney walls.
Flue liners should conform to ASTM C 315 (Standard
Specification for Clay Flue Liners). They should be
thoroughly inspected just prior to installation for cracks or
other damage. Steel should be ASTM-A 36 (max of: 0.26%
Carbon, 0.04% Phosphorus, 0.05% Sulfur).
