that they could join, are not permissible,
unless they are separated by at least three
inches of sound liner.
e. A maximum of seven cracks, each crack not
exceeding one inch in length, is permissible in the liner
adjacent to the dome end.

burning, which would reduce liner wall thickness, thus
weakening the structure.
