3. Firestop Spacer/Vent Installation
Frame an opening and install a firestop spacer
whenever the vent penetrates a ceiling/floor area, as
shown in Figure 7. Frame the opening with the same
sized lumber as used in the ceiling/floor joists. Unless
the flue is offset, the hole should be directly above the
appliance. DO NOT pack insulation around the vent.
Assemble vent sections as per manufacturer's
specifications.
