Installing The Return Air Grille/Panel
1. Install the return air grille/panel assembly (Figure
41). Center, level and plumb the frame inside the
framed opening. Push the assembly into the opening
until the gaskets compress against the cabinet, and
the frame face is tight to the nished wall.
Note: Shims should be used to make up the space
between the studs and the panel frame at the
locations of the fasteners on the panel frame (4).
Adhere them to the panel frame to keep them in
place (Figure 41).
Note: Be sure the bottom ange of the door frame
slides beneath the cabinet ange, as shown in Figure
41. This seal must compress between the bottom
panel ange and the bottom cabinet ange when
the installation of the panel door frame is complete.
2. Check that the panel door frame is centered within
the opening and seals completely to the cabinet
return air opening. Also conrm that the room
side ange of the frame is level, plumb and rmly
against the drywall. Secure the hinged panel door
frame with the 4 screws provided.
