Are you referring to a line in the config or underlying module. Can you point me to a good example or tutorial? (i.e. teach me to fish and I will never go hungry again). Thanks again and in advance for your time and patience.

The question as I understand it, because I have been searching for the same thing, is how to set up what amounts to a boolean statement, or even "manually" change the fuel source. I have tried a number of ways to include three fuel sources while only requiring two (one of which always being the liquid fuel) at a time.
