OK, I thought you wanted to go after the wind current thing first, so if he had a super good draft it would overcome the down draft from the wind?BeGreen said:oldspark said:I first read about this happening many years ago and have seen it first hand, if you are getting a direct wind current fighting the draft I am not sure who' going to win.

Agreed, it looks like the wind blowing against the roof there may be creating a local downdraft. Anything that can improve draft, even slightly will help. That could mean eliminating horizontal run(s), 90 deg turns, sealing every joint and connection, insulating liner and pipe, etc..
