I'm installing a 316 steel flex liner in my basement fireplace chimney, which is more or less directly below the upstairs chimney. Because of this, there is rather severe turn in the existing terracotta liner. I have the liner to this point and can't seem to make the turn to continue. Seems like a common enough problem, but I haven't figured out the common solution. I'm using a pull con from the bottom with a rope and pulling the liner through the chimney.
