I also know the meaning of "Purge". It means to remove something we don't want (air) and replace it with something we want (gas). If Doug is to stand by his position, he should stick with "refill"
I may not be an "RV" specialist but I am a flow, pressure, control valve, burner and regulator specialist so I believe I am qualified to make an observation.
First of all, I seldom run my tanks empty. I remove my tanks when low and take them for refill. When full I reconnect them. The disconnect time can vary from 10 minutes if my RV is at the refill station to hours if I have to take them for refill. Usually it is the longer.
When reconnected, I open the tank valve. When that valve is opened, all the lines are charged by the regulator, to regulator pressure, in a very short amount of time. Now if the lines are full of gas but at a low pressure then they should pressure up with gas to regulator pressure and if it is all pure gas then the stove burner should light instantly. Mine doesn't. If you don't try to light it, you should be able to smell it. I can't. You should be able to hear it, I can. This tells me there is an unburnable mixture coming out of the burner. If it were too rich, I should be able to smell it while unlit, I can't. If it is too lean, i.e. too much air, there would be very little if any odor, which is my experience. The only way to tell for sure would be to take a portable flammable gas analyzer and test what is coming from the burner. Since I work in the O&G industry overseas, I can't check one out for the month and test it. I can only rely on my observations and experience. My observation is it acts like air. Unless someone proves me wrong by gas analysis, I stand by my observation.
