Wall Boxes
General Information
The following instructions are general
recommendations for installing wall
intake boxes. Consult the architectural
plans for specific requirements.
Additional materials required to com-
plete any specific installations (such as
duct connections, metal mounting
plates, or flanges)
are not furnished by
Trane.
For best results, all air intake boxes
should be removable from outside of
the building. Weep holes must be at the
bottom to permit free drainage. A posi-
tive air and moisture seal should be
provided around all edges.
General Instructions
Trane wallboxes are illustrated in
Figures 58 & 59 and each lists the
wall openings required for wallboxes.
Vertical louvers in the wall intake box
provide extra strength for a high load
bearing capacity. The lintel may be
omitted on masonry wall installations.
Weep holes are provided in the outside
face of the bottom channel in the wall-
box frame. Install all wall boxes to per-
mit free drainage through the weep
holes to the outside of the building.
All wallboxes are furnished with dia-
mond pattern expanded aluminum bird
screen.
Note: H1 (horizontal), V1 and V2 (verti-
cal) wall models are all unflanged. H2,
V3 and V6 are flanged.
