Before: We documented the GE dryer and its semi-rigid transition connection before servicing the exhaust system. Process: We accessed the roof termination, removed accumulated lint, and opened the dryer lint passage for cleaning. After: The photos show the removed lint and the roof outlet check. We recorded 1,791 feet per minute of air velocity at the termination during service. This measurement documents outlet velocity; it is not a whole-system airflow-volume measurement.
