Features and Installation
PROCEDURE C
Redirect the louvers at the back of the wall
sleeve to 60°angle as shown in the FIG 15.
The use of pliers is recommended.
If the wall sleeve already has a rear grille, skip to
step 4. If the wall sleeve does not have a rear grille
or louvered panel, install the plastic grille from the kit.
Cut the plastic grille to 26-1/2" wide and 15-1/2" high
or to the sleeve dimensions. Place the plastic grille to
the inside of the wall sleeve at the rear flange.
Fasten the 4 washer screws to secure the grille
to the wall sleeve. If you need plastic nuts to
mount plastic grille to the inside of the wall
sleeve, there are plastic nuts in the installation
kit. The nuts are installed from the inside of the
sleeve and are pressed into the square holes of
the rear flanges.
Remove the backing from the Horizontal
Insulation strip 13/8" x 13/8" x 273/16" and attach
that to the inside bottom of the sleeve as shown
below. Remove the backing from the Around
Insulation strip 13/8" x 13/8" x 611/2" and attach that
to the inside front of the sleeve as shown below.
If the depth of your existing sleeve is less than
or equal to 18”, skip to step 7. Otherwise, cut
the baffles and the support blocks according to
Length "A" in the table below.
Remove the backing from the support blocks
and attach them to the inside of the wall sleeve
as shown FIG 20. Slide the baffle into slots of
the support blocks
