doors or spaces open to the outdoors. These include
attics* and crawl spaces. Follow the National Fuel Gas
Code NFPA 54/ ANSI Z223.1, Section 5.3, Air for Com-
bustion and Ventilation for required size of ventilation
grills or ducts.
*IMPORTANT: Do not provide openings for inlet or
outlet into attic. If attic has a thermostat-controlled
power vent, heated air entering the attic will activate
the power vent.
IMPORTANT: Vent-free heaters add moisture to the
air. Although this is beneficial, installing heater in
rooms without enough ventilation air may cause mil-
dew to form from too much moisture. See Fresh Air
for Combustion and Ventilation, pages 3 through 5.
