Provide extra fresh air by using ventilation grills or ducts. You must provide two permanent
openings: one within 12" of the ceiling and one within 12" of the floor. Connect these items
directly to the outdoors or spaces open to the outdoors. These spaces include attics and
crawl spaces. (
See Figure 2
)
IMPORTANT: Do not provide openings for inlet or outlet air into attic if attic has a thermostat-
controlled power vent. Heated air entering the attic will activate the power vent.
