in air duct distribution systems serving heating systems in which the rated

Intent | Intent 1: To limit the probability of an inadequate number or placement
of warm-air supply outlets, which could lead to an inadequate distribution
of warm air in crawl spaces, which could lead to temperatures in certain areas
of the basement falling below the minimum indoor air temperatures [see Sentence 9.33.3.1.(1)], which could lead to condensation, which could lead to
deterioration, which could lead to compromised structural integrity, which
could lead to harm to persons. |
