12. Install the vertical termination—The final step involves
installation of the SV4.5CGV-1 vertical termination. Align
the termination over the end of the previously installed
section, adjusting the radial alignment until the four (4)
locking dimples of the termination are aligned with the
inlets of the four (4) incline channels of the last vent sec-
tion. Push the termination down until it fully engages, then
twist the termination clockwise running the dimples down
and along the incline channels until they seat at the end of
the channels. If the vent system extends more than 5 ft (1.5
m) above the roof flashing, stabilizers may be necessary.
Additional screws may be used at section joints for added
stability. Guide wires or roof support assemblies may be
attached to the joint for additional support on multiple joint
configurations.
NOTE: SV4.5VF firestop/spacer must be used anytime vent pipe pass-
es through a combustible floor or ceiling. SV4.5HF firestop/spacer
must be used anytime vent pipe passes through a combustible wall.
