I'm trying to concentrate a bit more smoke on my long, slow brisket smokes and bought an A-maze-n box for the purpose. Problem is, with the airflow in my Traeger Texas, it tends to blow out regularly. Anyone else have this issue and hopefully a fix for it? Is there a preferred position or orientation for the box? The A-maze-n worked great in the cold smoker but just doesn't stay lit in the main grill.
