Hi, i am cleaning my wood stove pipe for the first time. Please see pics.. I removed 6 screws at the middle and bottom of my 2 pcs. of 6" pipe. The top section slid down. There is 1 screw at the top that did not get screwed through the tailpiece. There was just a dent where it was. There are 3 holes on the top pipe but the installer only used 1 screw in the front, which was not screwed through the tail piece, see pic. I am thinking it might be just a set screw? Or does it get screwed through the tail piece??
