TO PREPARE THE REAR WALL
CUTOUT OPENING AND EXHAUST
ADAPTOR/MOUNTING PLATE FOR
WALL-VENTED:
1. Place the mounting plate against the rear wall as
described in step 5 item 1 (page 14).
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 (page 14) to continue. After
completing the installation of the mounting plate,
again check the rear damper for free movement to
assure it will operate properly.

PLATE TO THE WALL
