Measure and frame out the outside wall plenum opening
9000 / 12000 / 18000 BTU/h
The plenum cut out dimensions are 24 5/8"
wide x 30 7/8" high. The bottom of the rough
in opening must be 3/4" from the surface the
unit will sit on.
Measure your outside wall as shown in the
illustration. Cut, frame, and square rough
opening. The Wall plenum has a 3/4" break all
the way around to cover the rough cut ope-
ning or required shim.
If the installation will utilize an auxiliary drain
pan the drain pan must be a maximum of 3/4"
tall. If the drain pan to be used is taller, the
unit must be raised within the auxiliary pan by
the difference in height of the drain pan and
3/4".
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 FLAS-
HING, SHIM AND CAULK FOR A WEATHER-RESISTANT INSTALLATION.
IT IS THE RESPONSIBILITY OF THE CONTRACTOR TO PROPERLY INSTALL THE PLENUM AND MEET
BUILDING CODE REQUIREMENTS.

Install Architectural Louver on the Outside Plenum
NOTE: The VPAL2 Architectural
Louver is best installed onto the
Outside Plenum (Part A) prior to
Wall Plenum installation. Louver
installation is easier at this point,
and it will help keep the Wall
Plenum square during installation.
