If the top portion of your fireplace and chimney looks like this picture than it is a prefabricated or factory built chimney. Only the top round portion is the chimney cap. The round visible pipe is the outer chimney pipe. The storm collar is at the lower portion of the pipe and stops water from entering between the pipe and the chase pan. The flat piece of metal where the pipe enters the chase is most often referred to as a chase pan or chase cover. It blocks water from entering the hollow chase down to the roof. If the chase cover becomes rusty it should be replaced immediately in order to stop more costly damage to the system.
