At issue, I believe, is the pressure rating of the on-board gas tank. The
manufacturer doesn't believe it will survive the higher pressure of the
butane/propane mix.
Conversely, that higher pressure is what makes it work so well in the cold.
A number of gas tanks are rated for the butane/propane mix, but some
aren't. If the maker says use only 100 percent butane, then you should
follow the recommendation.
FYI, the Accucraft, makers of the Ruby, say 100 percent butane in their
literature, but I know of a number of people (myself included) who use
butane/propane will no ill effects. But you are doing so at your own risk.
