A method of assembling an air distribution system for use in a rotor blade of a wind turbine. The rotor blade includes a sidewall at least partially defining a cavity extending from a blade root towards a blade tip. The method includes positioning at least a portion of a manifold within the cavity and coupling the manifold to the sidewall. The manifold extends from the blade root towards the blade tip and has a root end and an opposing tip end. A passage is defined from the root end to the tip end. A flow control device is coupled to the manifold root end and configured to channel air through the manifold. A bypass flow assembly is coupled to the manifold and configured to channel air through the air distribution system with the flow control device in a non-operating configuration.
