of vertical vent termination and install.
If there is a room above ceiling level, fire stop spacer
must be installed on both the bottom ad the top side
of the ceiling joists. If an attic is above ceiling level a
7DVAIS (Attic Insulation Shield) must be installed.
The enlarged ends of the vent section always face
downward.
