I have a woodstove that vents out the back. I am upgrading to Class A 6 inch pipe. The stove sits at 30 degrees to the wall where my thimble will be located. I need to redirect my horizontal pipe 30 degrees so the pipe reaches the thimble at the right angle. The stove sits in the opening of a beautiful fireplace so I have only 10 inches of headroom. Thinking about Duravent DVL. Nobody makes a 30 degree elbow for the black indoor stovepipe. But the DVL for outside has 30 degree elbows. Can I use the silver outdoor chimney in my firebox before exiting thru the thimble?
 
DVL is stovepipe, strictly for indoors. The shiny 30º fitting is sounds like Class A chimney pipe which is outdoor pipe. This sounds cumbersome. There probably is a better way. Can you post some pictures and maybe a sketch of what is trying to be done?
 
I would just use a single wall adjustable elbow. But note that single wall requires 18" clearance to combustibles.

Yep, that's why it would be helpful to have the full picture before making a recommendation. There are 15 and 30º single wall fittings, but are they appropriate here? The connection between "converting to class A" and" stove sitting at the opening of the fireplace" needs clarification starting with the conversion to Class A chimney pipe. Why Class A instead of an insulated, 6" liner?
 
It's ok for indoor use, exceeding requirements, just overkill.
