Ventilation Air From Inside<br />
Building<br />
This fresh air would come from an adjoining<br />
unconfined space. When ventilating to an<br />
adjoining unconfined space, you must provide<br />
two permanent openings: one within<br />
12" of the ceiling and one within 12" of the<br />
floor on the wall connecting the two spaces<br />
(see options 1 and 2, Figure 2). You can also<br />
remove door into adjoining room (see option<br />
3, Figure 2). Follow the National Fuel<br />
Gas Code, NFPA 54/ANS Z223.1, Section<br />
5.3, Air for Combustion and Ventilation for<br />
required size of ventilation grills or ducts.<br />

WARNING: Rework worksheet,<br />
adding the space of the<br />
adjoining unconfined space. The<br />
combined spaces must have<br />
enough fresh air to supply all<br />
appliances in both spaces.<br />
Ventilation Air From Outdoors<br />
Provide extra fresh air by using ventilation<br />
grills or ducts. You must provide two permanent<br />
openings: one within 12" of the<br />
ceiling and one within 12" of the floor.<br />
Connect these items directly to the outdoors<br />
or spaces open to the outdoors. These spaces<br />
include attics and crawl spaces. Follow the<br />
National Fuel Gas Code, NFPA 54/ANS<br />
Z223.1, Section 5.3, Air for Combustion and<br />
Ventilation for required size of ventilation<br />
grills or ducts.<br />
IMPORTANT: Do not provide openings<br />
for inlet or outlet air into attic if attic has<br />
a thermostat-controlled power vent.<br />
Heated air entering the attic will activate<br />
the power vent.<br />
