Abstract
An ember and flame resistant resettable automatic soffit vent includes a tray with ventilation openings formed in its floor. A mesh screen resides on the floor of the tray spanning the ventilation openings. A flat slide resides atop the screen and also has ventilation openings that match those of the tray. The slide has an open position wherein its ventilation openings align with those of the tray to allow airflow through the vent and a closed position wherein its ventilation openings are misaligned with the ventilation openings of the tray to close off airflow through the vent. The vent can be manually moved between its open and closed positions and one or more tension springs and a thermal link assembly cooperate to move the slide to its closed position if the vent is exposed to a high temperature cause by a fire very near a home. The vent also can be manually closed by a homeowner when a fire is threatening and then manually reopened when the fire threat passes without destroying the automatic closing feature of the vent.
