If I'm using beads and they begin to die down I put a few lighters on top of the CO and light up the chimney on the lid. It will give the roast or veggies a nice little boost until the beads are ready to distribute.

I have been doing this a lot lately and the seasoning has not been damaged. Keep an eye on the internal temp as you may need to remove the chimney earlier (depends on what's cooking)

A good trick try it out!
