Hello Profveggy, glad to hear from you. Welcome aboard, you will learn very much from this sight. I would like to see pictures of your stove. As far as not enough chimney to burn, that suprises me. Look at the pics of the stove that was mine for one week( friend needed heat source so I gave it to him ) it burned great with 6 feet of pipe. Post pics if you can. I come across all kinds of stoves and just like to tinker and half ass restore them. The Shenandoah I had was the first and only one I have ever seen, would love to see yours. Look forward to hearing from you.
