Hold ash and disturb airflow. Take it out if you want.

I would think that it makes your grill heat up more efficiently by reflecting the heat back up versus heating up the bottom part of the grill..

My 1150 runs the same with or without it. I also don't worry about how even my temps are across grill.
I'm more of a reactionary person.
