I found a great way to stop the wind from hitting my burner. I had some coil stock from reduing my house years ago. It's in a circle anyway, just measure the diameter you need. I just used a few gatoe calmps to keep it in a circle. Cheap, easy, and worked like a champ in 25 mph wind. I'm sure a siding guy would have scrap around for almost nothing. I'm sure someone has already thought of it.
