@@amersohail7988 If you see my videos carefully, you can understand where is the bypass line installed. Bypass line using during the equipments maintenance.
Poor planning on installation. Why was this sheetrocked over and cut open on install. That is bad planning and scheduling. Sheetrockers should have left the opening for the grill, it should have been pre planned, and trimmed out so sheetrock could be finished up to that hole. What a mess.
