Yes like my dad said to me long ago, wrap it tight. I cut it so that it just wraps around the stand and since it is already in a roll it wants to stay that way. I basically have it flexing on the back of the burner guard and it stays there without any adhesion. No need to cut any holes in it as the back of the burner is the air mix control, keep it tight. This leaves just enough room for a long igniter above the burner shield. The radius is almost exactly the size of my 10 gallon pot so all the heat stays on it. It also helped a ton with the issue I had with my immersion chiller. The hoses would get residual heat and start to semi-melt. I was wrapping a towel around them, still do, but this cut down on that problem as well.
In Az? get any rain tonight?
