That's what we're here for
I didn't realize that your stove probably hadn't run in a while. Tearing it down is probably the best thing for it. I've never torn mine completely apart, but probably should.
McGiever is again correct about the blowers. Vacuum them out, oil them, and make sure they spin freely.
As far as the bypass wire goes, that won't hurt anything, really, but it will override the timer settings that I detailed previously. In other to words, the stove will think that T-stat is constantly calling for heat. This will cause the feed motor to run continuously. This will in turn (if your stove were feeding properly) give you a constant enormous fire and more heat than you might want. If you do not have (or don't want) a T-stat, you can remove the jumper wire and run it completely off the timers. You could hook up pretty much any two wire T-stat if you wanted to. The one that came with mine was a pretty cheap mercury from Honeywell. I replaced it with a somewhat better digital, but as long as it accurately works you're okay.
I would be somewhat reluctant to take out the grate as it is nearly impossible to find. While our stoves and the Magnum are very similar, the Magnum uses a two piece grate, ours a single (though mine is split down the middle.) They are not interchangeable, and very hard to find.
Make sure that the fines cleanout under the grates is clean and then closed. There's a handle inside the stove, under the grate, on the left, that can be pulled forward. This will open up two holes under the grate where fine pieces of ash and coal will fall. Since this can block the path of the combustion air, make sure that it's clean (or as clean as you can get it.)
Let us know how you make out or if you run into any problems in the meantime. Good Luck.
