unconfined space. When ventilating to an
adjoining unconfi ned space, you must provide
two permanent openings: one within 12" of the
ceiling and one within 12" of the fl oor on the wall
connecting the two spaces
(see options 1 and
2, Figure 2).
You can also remove door into
adjoining room
(see option 3, Figure 2).
Follow
the
National Fuel Gas Code, ANSI Z223.1/
NFPA 54, Air for Combustion and Ventilation
for required size of ventilation grills or ducts.

Ventilation Air From Outdoors
Provide extra fresh air by using ventilation
grills or ducts. You must provide two perma-
nent openings: one within 12" of the ceiling
and one within 12" of the fl oor. 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, 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.
