Lets try this one more time! You have 2 issues going on as far as I can tell.
1st - There is a draft issue. The wind is blowing hard enough to stop your draft for a few seconds allowing smoke to build up in the box and then come out through the seems. (Path of least resistance)
2nd - There is a stove issue. You should not have that much smoke coming out of the seems of the stove. The seems need to be resealed. When the situation stated above occurs the path of least resistance should be the air intake and possibly the door seal not the seams of the stove.
Have your dealer send the installer back out to fix the issues on his dollar ASAP.
