Understanding Class A Ovens - Process Heating

Nov 01, 2002 Class A ovens must have a purge period before the heat source can be energized. This purge period must be long enough to get at least four air changes of interior volume. An oven with an interior volume of 100 ft3and exhaust ventilation of 125 ft3/min would require 3.2 min purge time (100 ft3x 4 = 400/125 = 3.2 min).
