Place the exhaust louver gasket onto the flange on the blower housing.
Install the louver housing assembly onto the blower housing and install and tighten the fasteners.

Install the damper actuator and the two pins that retain it. If there were clamps holding the electrical cable, they
should be re-installed.
Plug the electrical cable into the receptacle on the control van.
