INSTALLATION
STEP 5: INSTALL THE MOUNTING PLATE
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.
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.
