Step 1. Pick a potential location for installation.
Check that the size of rough opening matches
what is listed in Table 1 for the model being
installed.
Step 2. If there is no ceiling and the attic ladder will
t between the joists so that no joists need to
be cut, go to Section 1.6,

but one or more joists need to be cut, go to
Section 1.5,
page 12, “CUTTING THE CEILING
JOISTS”. If there is a ceiling at this location, you
will need to inspect the area above this location
as described in steps 3 and 4.
Step 3. Go into the overhead space and nd the area above your chosen location.
