Install the two air duct boxes in their framed openings.
(Fig. 46)
If desired, paint the inner surface of each air duct tube
for about 6” (152mm) to eliminate reflected glare; attach
this end to the air duct box flange.
Cut and fit the air duct tubing between the air duct
boxes and the top of the cabinet.
NOTE:
The duct-
ing used to connect the duct outlets on the enclosure
cabinet to the remote duct boxes is Class O/Class I.
Use no other class of ducting for this application. In
certain areas, local building codes may prohibit the use
of flexible ducting in enclosed spaces. In such cases it
is acceptable to use solid cutting that meets local code
requirements.
Cut the tubing a few inches too long with a serrated
kitchen knife - it can be compressed during installation.
The duct tubing must fit onto both the duct box and the
cabinet flanges the full length of the flanges 2” (51mm)-
all the way around.
Secure each end of the ducting to the appropriate
flange with three of the sheet metal screws provided.
Holes for the screws must be drilled first around the
perimeter through both the duct tubing and the flange
with a 1/8” (3mm) drill bit. Space the holes as evenly as
possible around the flange.
8. Install the elevated base.
Slide the base into the
cabinet until it contacts the rear wall.
9. Install the optional cabinet convection blower kit.
The blower kit is an integrated unit housed in a metal
shell. ON the front side there is a flange perpendicular
to the housing. When properly installed, this flange
rests on the elevated platform and is fastened to it with
screws.
The back side of the blower housing has a flange that
rises parallel to the back side panel. This flange is fas-
tened with screws to the rear panel of the cabinet.
The power cord is routed to the left where it can be con-
nected to the lower receptacle of the cabinet junction
box.
10. Finish the wall surface surrounding the chase.
Cover the room’s wall area surrounding the chase with
a material of your choice, but carefully observe the
noncombustible limits as described in Step 6b - drywall
or other combustible wall covering applied to overlap
the outer edge of the trim panels must not extend inside
the combustible limits. These limits also apply to any
combustible edge molding used to trim the raw edge of
the drywall.
In addition, combustible edge molding must not pro-
trude into the room more than 2” (51mm) from the panel
surface.

In addition to installation on the front, duct boxes may
be mounted on the sides of the chase or vented into adjacent
rooms, but in no case below the top of the cabinet.
