Chimney Stack Airflow System features 4-6″ diameter stainless steel chimney with multi-position damper, 24-36″ stack height, and intake baffle for precise temperature and smoke management. The system creates optimal draft through the firebox while preventing backdraft and maintaining clean combustion.
Adjustable from fully open (maximum draw for hot/fast cooks) to nearly closed (low-and-slow smoking), this configuration delivers Tony’s BBQ-level consistency across 12-18 hour brisket smokes and delicate poultry finishes.
