Two sections of the OneGear™ plenum should now be fully installed .
Apply silicone to gaps or holes located at bends and corners.
23. If a Bulletin 7712/7791 product is ordered, an end plate (81021-288-
89/90) and extension with screen will be required (81021-288-60/62,
and 81021-288-61). Install the end plate with M8 hardware.
If an end plate is ordered with no exit hole, it must be
installed first or it will be very difficult to attach to the
top plate, see Figure 5.13.
