Towards the top or in the middle? I would need to know as I would need either the 6" or the 8" depending on where the install goes.
Install anywhere in the vertical pipe, NOT in the stainless steel chimney. I don't know whether the 6" control is adequate, or whether you need to replace part of the 6" pipe with 8" so you can use the 8" control. Check the sizing chart that Razzler referred you to.
Most people use the Field Controls RC draft control (barometric damper). You can replace part of the pipe with a tee and install it in the tee. Or, you can cut a hole in the pipe and install it with the strap and adapter that comes with it.
The same control is used on a lot of oil burner installations. You can probably get it from a local heating supply dealer. Comes in either black to match the stovepipe, or in gray.
