Just picked up what I believe is a mid 90s Jamestown j1000. It's kinda rough but I only paid $300 for it and figured with some cleaning and a new coat of pain it could make a nice stove. My question is am I missing something on the back? It looks like something screwed around the intake and combustion fan. It also looks like I'm missing the combustion fan pipe adapter. Not sure where I can get one? Also what's the best way to test everything to make sure it is completely functional? This is my first pellet stove and won't be hooking it up til next fall as winter is almost over. Can I just run it outside? Here is a pic of the back.
