Hi Josh, I don't have the vortex basket but have used a fire dial a few times which works in a similar fashion. The best advice I can give is not to light too much charcoal to begin with. As long as it's reasonably warm outside where you are, I fill the charcoal ring, and take about a half a regular chimney size out of the center and light it up, then dump it right back in the middle and set all the bottom vents to about 1/3 open and the top to about one half and see what happens next. If you have an ATC, I'd probably light it off the same way. I'm sure others will chime in here eventually, but this is the best advice I can offer.
If you light off too quick and need to get it under control, I'd put a aluminum pan on the bottom rack and fill it with cold water.
