I got some answers thanks. I am pretty sure I have too much pressure
in my system, since the air was not evacuated. Now, can I just open
the overflow valve on my tank and wait until no more propane
escapes??? The little tag on it says that filling must stop once
liquid (propane) comes out. Right now if I open it not much liquid
comes out, it is mostly gaseous. I left it open for about 45 sec and
it was still coming out. The smell is getting less now but still
there and I can't have it. I don't see any leaks anywhere with bubbly
solution.
The fridge works great, as do burners.
I basically need the screw type overflow valve explained. Thanks!!!

Cheers
