Ventilation Air From Outdoors

Provide extra fresh air by using ventilation grills or ducts. You must provide two permanent open- ings: one within 12" (30.4 cm) of the ceiling and one within 12" (30.4 cm) of the floor. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces. Follow the National Fuel Gas Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation for required size of ventilation grills or ducts.

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.
