Fig. 46 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.
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. |
Fig. 45 Wiring for an installation using the optional cabinet convection blower kit. When the kit is not used, only the upper receptacle is live.
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.
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.
