The wind is blowing like crazy here, but it is only about 30 degrees, that is an amazing combination for us. Usually when it is blowing like this in the winter it is too cold to mess around outside. So with the "balmy" weather I ran out to my ct and decided to do an acid test burn with the Nuway propane stove and my modified vent cap. I know that most of you have seen the changes I made, but since some may not have I will detail them again here.
The wind is pretty steady at about 30 mph with gusts up into the 40s. It nearly blew me off of our side porch. I ran the stove once before in a wind close to this, but I got to thinking that maybe the direction the wind was coming from might make a difference.
This is the 3 inch vent cap that I got from HD.

At first I tried to just run it with the unmodified cap right out the side. That was okay with no wind, but when the wind came up I was getting exhaust in my door when I would open it, and the wind would blow the stove out. Next I tried extending the pipe outside the ct to above the roof. No exhaust in my door, and it was better in the wind but still would occasionally flicker or blow out. I even tried a different "high wind" cap. It didn't fit well.
Finally I thought to modify the cap I had. I brought the exhaust point back down a horizontal ending on the side of the ct, but now I used aluminum tape to block the two vent ports on the sides, leaving the top and bottom ones open.
It worked beautifully! With the side vents blocked the exhaust goes straight up and the flame isn't bothered by the winds I have encountered so far. Unmodified the side vents on the cap were scooping the wind in. With them taped shut the wind can't come in the sides.
Now for today's test. If it can burn okay in this wind, it will be okay in just about anything.
Score!! Nary a flicker. The wind isn't bothering the flame at all.
