Ventilation Air From Inside Building

 

This fresh air would come from an adjoining unconfined space. When ventilating to an

 

adjoining unconfined space, you must provide two permanent openings: one within 12"

 

of the ceiling and one within 12" of the floor 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 NFPA 54/ANSI Z223.1, Section 5.3, Air

 

for Combustion and Ventilation for required size of ventilation grills or ducts.

WARNING

Rework worksheet, adding the space of the adjoining unconfined space. The combined spaces must have enough fresh air to supply all appliances in both spaces.

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 floor. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces.

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.
