wwwsmith, you are on the right track. The problem though is likely when we open our valves. I know when I dispense propane at work. I have to open all the valves real slow. If you open a valve too fast, it "vapor locks" - sort of - then it wont dispense anything until the "lock" flows thru and opens the lines. That "I THINK" is why we have to light the stove top first and clear the lines, before any other appliance works.
I started with nothing, and still have most of it left
