Ditto; Most new stoves don't really even need an in pipe damper as you can literally shut them completely down by closing the in stove vents. Even my old Fisher stoves will do that and the manual even says no damper required. Pretty much any stove that has a door gasket is like this. Before you open the door, simply open the damper and input vent all the way for 20 seconds, then crack the door and inch or two for a few seconds, then fully open. I have had the wind cause that too. Not so much the wind speed as the direction, height of pipe and shape of roof. Your pipe is supposed to extend two foot above the highest point of the roof. If your pipe goes through at a low point in the roof, that can be hard to achieve without an elaborate brace though. With my Fisher with double doors, I have a hard time opening the second door without some kind of smoke coming in but I also had a pretty short pipe on it. A shorter pipe won't give
enough draft. Your manual will probably specify a minimum length/height for your pipe. Elbows also restrict the draft. Just opening the damper all the way, waiting for 20-30 seconds, cracking the door and waiting a few more seconds should do the trick for you as long as your pipe isn't too short.

If I am only for myself, what am I?
If not now, when?
