When considering placement of the duct on the inside and outside of the house, keep in mind the need to avoid wiring and structural members of the house. Locate the termination of the duct on the outside wall in such a manner as to preclude the possibility of obstruction by snow, leaves, or other materials. Screen the outside termination with a ¼” x ¼” mesh rodent screen, and cover it with a rain/wind proof hood. Periodically check the screen to ensure it is not blocked by debris such as spider webs or leaves
