install. The side plate with the humidifier port needs to be on the side of the 
humidifier that is closest to the 6 in. (155mm) hole cut in Step 10.

blade has adequate clearance to move back and forth between the summer and 
winter positions. Secure the flex duct in place with the plastic connector strap.

duct to the humidifier 
over the top of the 
connector strap.
