I bought a new one and watched as the tech did a changeover to
propane. While some may be shipped with the changeover already
installed, they are essentially the same unit.
Too bad I didn't know you a couple of years ago, I had 2 complete
propane furnaces I scrapped out, one was in really good shape, I just
couldn't imagine much of a market for them. I'd have gladly have given
them away.
