Intent

Intent 1:

To limit the probability that heat radiating from the fireplace opening to a hearth that rests directly on a combustible floor will raise the hearth temperature excessively, which could lead to the ignition of combustible building components, which could lead to harm to persons.

Intent 2:

To exempt certain fireplaces from the application of Sentence 9.22.5.2.(1), where the fireplace opening is raised sufficiently above a combustible floor to reduce the risk of raising the hearth temperature excessively.
