Appendix F. Exhaust Plenum System Details

Exhaust Plenum Extension

The exhaust plenum extension is an optional item that can be used to extend the exhaust plenum above the switchgear further

in the equipment room (Figure F.18). The exhaust plenum extension is provided in 36 inch lengths.

Figure F.18 Exhaust plenum extension details

NOTICE: Use of optional flange clips (Figure F.10) may be

used in lieu of the #12-24 x 7/8 inch hardware. Two flange

clips may be installed on each long exterior flange and one

flange clip may be installed on each short exterior flange.

Use of the optional flange clips will still require the

installation of the 3/8-16 x 1 inch carriage bolts at each

exterior flange corner.
