Figure 7
Measure and frame out the outside wall plenum opening
24000 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 1 1/2" from the surface the unit
will sit on.
Measure your outside wall as shown in the illus-
tration. 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.
If the installation will utilize an auxiliary drain
pan the drain pan must be a maximum of 1 ½"
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 1 ½"
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.
IT IS THE RESPONSIBILITY OF THE CONTRACTOR TO PROPERLY INSTALL THE PLENUM AND MEET
BUILDING CODE REQUIREMENTS.
Figure 8
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 installa-
tion.
