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:
• Make the box cutout for the rear wall duct.
– 1 piece mounting plate:
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. (Figure 28)
– 3 pieces mounting plate:
Use the wall template to determine 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.
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.
