1.Place the mounting plate against the rear wall as described in step 5 item 1.
2.Using a pencil, put dots through slots F and G, and through holes H and I. Remove the mounting plate and
draw lines extending through the points. This will give the location and size of the box cutout for the rear wall
duct.
•Attach the exhaust adaptor to the rear mounting plate by sliding it into the guides at the top center of the plate on the wall side. Push in securely until it is past the top locking tabs and in the lower locking tabs. Take care to assure the damper hinge is installed so that it is at the top and that the damper swings freely.
•Carefully guide the exhaust adaptor, now attached to the mounting plate, into the house duct, before using the screws to attach the plate to the wall. This will assure proper alignment for installation.
•Return to step 5, item 3 to continue. After completing the installation of the mounting plate, again check the rear damper for free movement to assure it will operate properly.
