APPLICATION:
Design and location, in heating, ventilating and air-conditioning
systems, of outdoor air intakes and exhaust outlets at the exterior of buildings described in Sentence
1.3.3.2.(1) of Division A.
This also applies to buildings to which Part 9 applies [see Sentence
1.3.3.3.(1) of Division A for application
of Part 9], with respect to:
- mechanical ventilating systems other than self-contained systems serving single dwelling units, as stated in Sentence 9.32.1.2.(2),
- the ventilation of storage garages for more than 4 motor vehicles in residential occupancies, as stated in Sentence 9.32.1.1.(3),
- the ventilation of all occupancies other than residential occupancies, as stated in Sentence 9.32.1.1.(2),
- heating systems, including requirements for combustion air, and air-conditioning systems other than those serving individual dwelling units, as stated in Sentence 9.33.1.1.(2), and
- air duct distribution systems serving heating systems in which the rated heat input exceeds 120 kW, as stated in Sentence 9.33.6.1.(2).
INTENT:
To limit the probability that the inappropriate design or
location of outdoor air intakes or exhaust outlets at the exterior of buildings
will lead to the introduction of contaminated outdoor air into buildings,
which could lead to negative effects on the air quality of indoor spaces,
which could lead to harm to persons.

To limit the probability that the inappropriate design or
location of outdoor air intakes or exhaust outlets at the exterior of buildings
will lead to the introduction of pollutants, such as carbon monoxide gas,
into buildings, which could lead to harm to persons.
