Two bi-metal disks in cap. One is redundant. In case you missed it. Use second click. For less vapor use the first one.
If you look at the cap the side of the cap opening the side that has the digger wants to flatten out. To tighten the cap, make it rounder or less round . All the caps are the same size. Doc
Now I'm confused. If we ignore the first click, and there is only one click, couldn't we end up over-cooking? I had no idea until now that there were two clicks at the beginning (warmed up) and again at the end (cooled). So...shouldn't we respond and quit torching when we hear the first click?
