We are replacing our 20+ yr old wood stove with a Scan 60 that we bought secondhand. Problem is we cannot even get the stove pipe installed and are at a dead end. We got the 6 inch piping but CANNOT get it into the port that comes OUT of the stove itself. Is there some kind of adapter or any tricks? I told my husband it CANNOT be this difficult, we are doing something wrong! any help would be greatly appreciated
