Cool. I realized I need a few extra parts, the flange to solder to the copper column, various grommets etc. It said it came with a tri clamp, and it did. Looks like I need two. There is a flange at the bottom of the can, and the block off piece is held with that one. I will need another to clamp column to the top.
It has a double bottom and that small rise allows the bottom flange to be even with the inside bottom of can, due to the space between that and the actual bottom of the kettle.
I have the two inch copper cap for my column, and pieces turning to side, and connecting to condenser. I will put a submersible pump in a 27 gallon tote, to cycle cold water through the condenser.
