Back9.22.2.2.(1)

ATTRIBUTION:

Functional Statement:

F01

To minimize the risk of accidental ignition.

Objective:

OS1.1

 

APPLICATION:

Minimum thickness of firebrick liners for masonry fireplaces constructed on-site, 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 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.
