Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or ducts. You must provide
two permanent openings: one within 12 inches of the ceiling and one within
12 inches of the oor. Connect these items directly to the outdoors or spaces
open to the outdoors. These spaces include attics and crawl spaces. Fol-
low the National Fuel Gas Code, NFPA 54/ANSI Z223.1, Section 5.3, Air for
Combustion and Ventilation for required size of ventilation grills or ducts.

supply all appliances in both spaces.
