My first low and slow overnight cook with the Party Q. Should there be any opening in the bottom vent besides where you plug the Party Q into the adaptor? I am confused because I am wondering if the only way the air will come into the bottom vent is if the fan is running. It is a little late but would someone that uses the PartyQ tell me the process they use for the PartyQ. At what point do you plug it in and turn it on? Thanks for your help. My family is coming at 1:00 tomorrow to help eat this 10 pound butt so I don't want to mess it up.
