| Intent | Intent 1: To limit the probability that firebrick liners of inadequate
thickness will lead to the excessive conduction of heat through the liners,
which could lead to an excessive rise in the temperature of the backup masonry,
which could lead to the ignition of combustible building components, which
could lead to harm to persons. |
