I had a problem this fall already,I burned my St Croix on low for 10-12 bags and it basically clogged up. I damaged the Clean out T(won't seal) and the 90 elbow,they over heated. I learned my lesson. I now have to take it apart and it was sealed with RED caulking. What am I going to need or to do to clean this up in order to get the new pipes together?
