I'm not sure venting the chamber would solve this problem. The problem isn't with the Smoke Daddy creating pressure, but the opposite-- the fan inside the Traeger prevents smoke from the Smoke Daddy from entering the cooking chamber. Eatapedia - Installing Smoke Daddy's Big Kahuna on my Traeger Love it! Now I can really set it and forget it, does not change more that 3 degrees. I ordered the Smoke Daddy PID Controller to replaced my Traeger Grill controller and that was the best thing I ever did. I may try to move the input to slightly above the grate. Thanks Smoke Daddy
