APPLICATION:

Minimum thickness of masonry walls surrounding the smoke chamber of 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).
