Abstract
A vent assembly includes a base, an intake duct, an exhaust duct, and a cap assembly. The base includes a vertically oriented, outward facing primary surface and defines a duct aperture that extends through the outward facing primary surface. The base includes a metallic material. The intake duct is coupled to the base within the duct aperture, and the exhaust duct is oriented coaxially within the intake duct. An end of the exhaust duct extends distally beyond an end of the intake duct. The cap assembly includes first, second, and third members, wherein at least one of the first, second and third members includes a non-metallic material. The first member includes an intake aperture aligned with the duct aperture of the base and is sized to substantially cover the outward facing primary surface. The second member includes an exhaust aperture sized to receive the exhaust duct. The third member is positioned distally beyond an distal end of the exhaust duct in a flow path of exhaust gases exiting the exhaust duct.
