Roof Curbs ship knocked down for ease of handling
and storage. The field assembly and mounting of the
curb to the roof is the responsibility of the installer. All
kits ship complete with pre-assembled side and end
rails, cross member supports, hardware, insulation and
gasketing. See Figures 26 and 33 for a complete parts
list for your curb. Check to see that all components are
included. Refer to Figurs 26 thru 33 to see if all other
field supplied parts are also on hand. Provide a suitable opening in the roof as suggested
per Figures 25 and 27. The return air opening has
been calculated to include a one inch clearance on
each side of the ductwork. The installer may determine
the opening to accept a return air duct to suit particular
needs.
