Last night I picked up a new to me super jack SJ125. (DANG ITS A HEAVY STOVE).Got it for $600, along with triple wall pipe. Stove looks to be in good condition besides the grate in the bottom. It's warped and broken, found one online for 300 bucks. Thinking about making my own for now. What's the best place to go through for replacement parts? Hopefully I can get the wiring mess cleaned up and get everything running. What size stove pipe is recommended for these? I have 6 inch in my garage now, was going to use that. Any tricks of the trade on these furnaces, please send them my way.
