| Application | Application 1: Minimum thickness and heat resistance of clay flue liners for rectangular masonry
or concrete chimneys that are not more than 12 m in height
and that serve fireplaces or appliances having
a combined total rated heat output of 120 kW or less, in buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9]. Application 2: This also applies to rectangular masonry
or concrete chimneys, 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 6.3.1.2.(1). |

| Intent | Intent 1: To limit the probability that slight variations in liner
dimensions and minor misalignments will lead to a mortar bed of less than 6
mm as required by CAN/CSA-A324-M, “Clay Flue Liners,” which
could lead to the ingress of condensed water vapour into the cavity between
the chimney liner and the surrounding masonry, which could lead to damage
to the masonry due to freeze-thaw stresses, which could lead to the collapse
of the chimney, which could lead to harm to persons. |
