The coils come in either a 2 foot or a 3 foot diameter coil. Put a corny in the middle, and grab the innermost coil hold it tight to the corny. Then start tightening the coil by lifting and manipulating the original coil. You will be turning the coil clockwise the whole time, as it winds from the inside of the original - and tightens on the corny. It helps to have a buddy hold the coil, as you make sure the newly tightened coil wraps neatly on the corny. Put that recirc coil in anyway... You will have a pump someday - and it makes it so much more efficient.
UPDATE: I tested it out today for the first time. 212 down to 120 in 5 minutes. Another 5 minutes down to 75, and five more minutes down to 60. 15 min total.... frickin' sweet...
