So I purchased an Earth Stove 1002c on Craigslist. After doing more research, I learned that it is a Catalytic Stove. So I began to look at it closer, and it turns out the Catalytic was removed and there's just a hold in the top for where the pipe fits. It appears that the previous owner might have modified it so there was no catalytic....my question is this....is it dangerous to use? One would think that it's bascially a big cast iron box and could still be used as a Wood Stove (I would put firebrick down) and put a damper in my pipe...is this possible...or should I be looking at a new stove (this stove is going to be used in my workshop which is just about 500 sq ft). Thanks!
