Bought a house last year, has a chimney system in place for a rear exhaust wood stove. Finally found the right stove to fit. Bought a 1986 Jotul 3. Stove was never used all gaskets look good, cream colored. Now i just need to connect it. Going to do a 6" Double wall black pipe because it will be sitting on brick hearth built when stove and chimney were installed. Already has thimble going through the masonry and external chimney. I cant seem to find it at any of the stores here on Eastern Shore of MD so am going to order online. Just need to know exactly what to get. Help is greatly appreciated was going to pay to have it connected but the local places wont call me back because its such a small job. I have now attached pics because i know everyone loves pics!! Help Please, need to know what to get, and if i need or should get a damper??? Thank you!
