If the vertical vent will penetrate a ceiling, use a
plumb line from the ceiling above the appliance
to locate center of the vertical run. Cut and/or
frame an opening about this center mark with
10-1/2" x 10-1/2" (267 mm x 267 mm) inside
dimensions (Figure 9-4).
Note: Vertical firestop/Spacer must
be used anywhere vent pipe passes
through a combustible floor or
