This fresh air would come from adjoining unconfined space.
When ventilating to an adjoining unconfined space, you
must provide two permanent openings: one within 12 inches
of the wall connecting the two spaces (see options 1 and
2, Figure 1). You can also remove door into adjoining room
(see option 3, Figure 1). Follow the National Fuel Gas Code
ANSI Z223.1’NFPA 54,

Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or duct. You
must provide two permanent openings: one within 12 inches
of the ceiling and one within 12 inches of the floor.Connect
these items directly to the outdoors or spaces open to the
outdoors. These spaces include attics and crawl spaces.

outlet air into attic if attic has a thermostat-controlled
power vent. Heated air entering the attic will activate
the power vent.

the adjoining unconfined space. The combined spaces
must have enough fresh air to supply all appliances in
both spaces.
