Before: The roof dryer exhaust termination had a metal screen packed with lint, restricting the discharge opening. Process: Hygienic Air accessed the dryer connection, cleaned the exhaust with rods, removed accumulated lint, and removed the lint-trapping screen from the roof termination. Dryer exhaust terminations must not have screens. After: Photos show the termination opening with the screen removed, the removed lint mat, the transition connector reattached, and the dryer returned to position.
