ICOT- You seem to have duplicated the stove as I remember it. However, your analogy to two candles is incorrect. Gas expands and when the gas i nthe pilot light is ignited, how do you think that the gas in the burner gets lit? By the expansion of the gas into the pipelet, it becoming ignited as it reaches the pilot light and then traveling BACK to the burner. So the gas is all one fire- there may even be a light flame in the actual pipelet, I don’t know,I have never looked. Unless you accept the fact that the gas in the burners expands and gets ignited during its travel through the pipelet, with the lit gas then returning to the burners, you will have to explain to me how the gas in the burners get ignited.
Also, once the gas is ignited ,how does it suddenly stop being a fire in the pipelet?
Unless you can answer these questions, I can safely assume that it is not two fires but one continuous fire. Candles are totally different things, they being totally separated and being ignited-just once- by one flame to the other. Till you solver for me the question of how the gas gets ignited, I can assume that it is one fire.
