6. Place the support clamp (provided with the support
box) inside the support box (at the bottom), and secure
to the pipe section. The clamp allows the support box
to support the weight of the pipe sections. Continue to
add pipe sections until you are above the roofline.
7. Complete the cathedral ceiling installation by following
the same procedures outlined in steps 7 through 9 for
vertical installations, pages 17-18.
8. Install the black trim collar around the outside of the
cathedral ceiling support box (Figure 5.19). The two
pieces of the trim collar slide over one another to allow
for easy adjustment around the support box. Using the
six screws provided, secure the four corners and the
overlapping sections of the trim collar to the ceiling.
You may want to predrill the holes for the overlapped
sections for ease of installation.
