A distribution manifold is provided for dispensing product into an airstream. The distribution manifold has a venturi port which has a front surface and a rear surface, as well as an air passage extending between the front surface and the rear surface. Additionally, the venturi port has a product inlet coupled to the air passage. The distribution manifold also has a bypass port which has a top surface, a bottom surface, a front bypass surface, and a rear bypass surface. The bypass port has a product throughway connecting the front bypass surface and the rear bypass surface. A wall of the bypass port defines a passage from the top surface to the bottom surface for insulating the passage from fluid communication with the product throughway.
