Functional Statement:

F01

To minimize the risk of accidental ignition.

Objective:

OS1.1

 

APPLICATION:

Hearths for masonry fireplaces constructed on-site whose opening is raised not less than 200 mm from a combustible floor, in buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9].
This also applies to fireplaces in buildings to which Part 6 applies [see Sentence 1.3.3.2.(1) of Division A for application of Part 6], as stated in Sentence 6.2.1.5.(1).

INTENT:

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.
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.
