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...

The bottle fill I did last week was from a 20 lb pot pressured to 87 lbs if memory serves me right. Mexico has butane at lower and warmer climes. When temps approach 10c Propane is added. At 5c Pure propane gas. At < -10c up to 3% methane is added. I use a glycerin-filled Ashcroft 0-300 PSI gauge.
