Air contamination Air openings
Combustion air and ventilation openings must comply with Section
5.3, “Air for Combustion and Ventilation”, of National Fuel Gas Code
ANSI Z223.1–latest edition, or applicable local building codes.
Canadian installations must comply with B149.1 or B149.2
Installation Codes.
See table below for minimum combustion/ventilation air opening
sizes. Where openings are required, provide two (2) openings —
one within 12 inches of the ceiling, the other within 12 inches of the
