Does this Smoke Daddy Heavy D look correct in my Timberline 850?

[Timberline850]

Measured before ordering it and their youtube says it works on a Timberline 850. Excuse the messy grill, but do these pictures all look ok? Or do I need to remove the lower heat shield so the Heavy D sits lower?

I also bought a large shallow water pan to help with the heat, but I'm wondering if I can smoke a brisket on the bottom rack and another brisket on the middle rack or if the bottom brisket is going to burn.
