LAC 51:XV.129. Ventilation Requirements [formerly paragraph 15:019]

A. Sleeping rooms shall be ventilated by natural or artificial means or both, and also provided with heating facilities. The combustion chambers of all heaters, heating systems, and other fired equipment shall be vented to the atmosphere. Other parts of the heating, cooling, and ventilating system shall be so designed, built, and maintained as to ensure that the pressure in the space from which combustion air is drawn does not become negative with respect to the atmosphere.
