be attached to the roof curb. Supply and return duct dimen-
sions are shown in Fig. 3A-3C.
To attach ductwork to roof curb, insert duct approxi-
mately 10 to 11 in. up into roof curb. Connect ductwork to
14-gage roof curb material with sheet metal screws driven
from inside of the duct.
14-gage roof curb material with sheet metal screws driven
from inside of the duct.
Secure all ducts to the building structure, using flexible
duct connectors between roof curb and ducts as required. Ducts
passing through an unconditioned space must be insulated
and covered with a vapor barrier. Outlet grilles must not lie
directly below unit discharge. The return duct must have a
90-degree elbow before opening into the building space if
unit is equipped with power exhaust.
