The plenum cut out dimensions are 24 5/8" wide

x 30 7/8" high. The bottom of the rough in open-

ing must be 3/4" from the surface the unit will

sit on.

illustration. Cut, frame, and square rough

opening. The Wall plenum has a 3/4" break all

the way around to cover the rough cut opening or

required shim.

IMPORTANT THE WALL PLENUM IS NOT DESIGNED TO CARRY STRUCTURAL LOADS. A PROPER HEADER

OPENING MUST BE BUILT INTO THE ROUGH OPENING. THE PLENUM REQUIRES FLASHING, SHIM AND CAULK

FOR A WEATHER-RESISTANT INSTALLATION.

CODE REQUIREMENTS.
