Jason hate to shock you, but you don't have any kind of furnace...other than in name EFM. If it has water in it, it is a BOILER and don't let 'Stroker Stoker Scotty' tell you any different!!!!
Glad to hear you are back fired up, and I hope you didn't just throw any old pipe in to replace the old rotted one. There is a direction orientation pin in the shoe of the pot and the pipe needs to have a number or 1/4" holes in the top section to send gasses into the burn chamber. If you did not drill the holes or didn't orient the pipe correctly, you should remove it soon and correct the mistake. Also, the chamber will get sludged up with wet coal, so hopefully you thoroughly cleaned up the receiver before reassembly.
I have tried to do the Stokerman removal method, which is excellent IF the 4 bolts that hold the pot base/shoe to the pot ARE removable. Unless you like the smell of PB Blaster, you probably won't succeed....in your lifetime.
DO NOT assume that they are, and if you snap one off, the bloody hands and arms and 4 letter word tirade will probably bring a couple EFM 911 calls. IF you get it apart ( 4 bolts) anti-seize the crap out of the damned thing. GRRRRRRrrrr!!!!!!!!!! In a factory setting and during final assembly, I will donate ALL the antiseize paste you could ever want, Chris. We'll be long dead, but some young buck will say: Man, those guys were thinking of the next guy!
The same holds true for AA and AHS. The shaft/fan assembly replacement.....GRRRRrrrr again. Or as Matt will attest, anything in or near the base on a AA, AHS, EFM, GJ. If it will rust or seize, make provisions to repair it some years down the road. Nothing other than high end machinery is built with serviceability in mind, but WTF, folks.
