Setting the Curb
Make openings in roof decking large enough
to allow for duct penetration and workspace
only. Do not make openings larger than
necessary. Set the curb to coincide with the
openings. Make sure the curb is level. Unit
must be level in both horizontal axes to
support the unit and reduce noise and
vibration.
