STEP 5: INSTALL
THE MOUNTING
PLATE TO THE WALL
TO PREPARE
THE REAR WALL
CUTOUT
OPENING
AND EXHAUST
ADAPTOR/MOUNTING
PLATE FOR
WALL VENTING
AND ROOF VENTING:
NOTE: If room vented installation is used, skip this
step.
1. Place the mounting plate against the rear wall as
described in step 5 item 1 (page 15).
2. Using a pencil, put dots through slots "F" and "G",
and through holes "H" and "1". 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. See Figure 28.
• 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.
See Figure 29.
• Return to step 5, item 3 (page 15) to continue.
After completing the installation of the mounting
plate, again check the rear damper for free
movement to assure it will operate properly.
