My Bayou Classic SQ14 burner seems to struggle quite a bit in the wind. I was thinking of using a section of circular heating duct to build a quick and dirty heat wind shield. The problem is, the stuff is made out of galvanized steel. Are there any potential issues (toxic fumes?) from using this stuff next to so much heat? Any other easy ideas for a windshield? (I unfortunately don't have access to many tools and no welding equipment so it's got to be pretty simple)
