Refilling 16 oz propane bottle off a 20# tank
I am missing the instructions on the procedure of how to do this, after buying the thread adapter to do so. Could someone walk me through the procedure? I assume I need a bleed off valve that...

A few suggestions: Most folks are filling more than one 1 lb. cylinder at a time. That's kind of good since the process can be scheduled and located away from anything that could be harmed.
All of the typical processes mentioned previously are valid, cold 1lb cylinder, invert 20 lb cylinder, etc.. Yes, a bucket of water will monitor seal integrity and heat the cylinder/contents so win-win. Coleman fuel cylinders develop the most seal leaks of any small ones we've filled. Bernzomatic is usually best, IIRC.
I would bet a doughnut that the explosive energy of a 20 lb cylinder is more than 20X greater than a 1 lb cylinder. Construction is different for higher operating pressures and the explosive result of the gas igniting wouldn't be linear as to weight difference.
Someone told me that the propane tanker I was on had the explosive energy of 20 Hiroshima's. Didn't seem possible but 1/4 of a Hiroshima would be too much.:(
