Thanks for the replies.
Looking at the calculator for the intake vents, it's saying I need total of 6.24 - 2"x3" intake opening.
My thought is 4 under FB grate for under coals and 3 in middle for fresh air intake.
Just wondering, are they saying total intake or need 6 openings in bottom under grate???
Hope this makes sense?
Next weekend is rib day, got back too late to do a cook today.
