I like it George av, what ever method you go with, I hope you have a couple of big ass young farm kids close by. U-haul refirgerator type hand cart (strap er tight) is how I got mine up a few steps & down 2. It is doable!!
All joking aside take a look at the stairs and made darn sure they are sturdy and if need be give them some sort of support. We do not want to hear that it was a 2 second transport to the basement.
The secret is ,which i found out to late , is to take everything out and off that you can,all 3 doors,hopper ,fire brick , and grates and 2 guys can manage it fairly easy !
