I would like to know about the proper way that propane tanks should be. I'm thinking that the bleeder valve should be opened during filling to let the air out.  My assumption is that when the gas is all burned out and the valves (tank and grill) is left open, then air must enter the tank. Maybe a better question would be does it matter that air is in the tank? Is there a way to bleed the air after filling? I've tried opening the bleeder valve on a half full tank, expecting for liquid gas to eventually come  out but it didn't.
On the other hand, perhaps I'm concerned for nothing. I'm just tinking that if air is in the tank then it won't produce as hot of a flame.
Thanks,
Rut
