ventilating to an adjoining unconfined space, you must provide two

permanent openings: one within inches of the wall connect-
ing the two spaces (see options and , Figure ). You can also
remove door into adjoining room (see option 3, Figure ). Follow
the National Fuel Gas Code NFPA 54/ANS Z3.. Section 5.3,

Air for Combustion and Ventilation

grills or ducts.

Ventilation Air From Outdoors

Provide extra fresh air by using ventilation grills or duct. You must
provide two permanent openings: one within inches of the
