AIR FOR COMBUSTION AND VENTILATION OUTDOORS

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