For Vertical Runs - The vent system must be supported
every eight (8) feet (2.4m) above the fireplace flue outlet by
wall brackets. To install support brackets for vertical runs:
• Attach wall brackets to the vent pipe and secure the wall
bracket to the framing members with nails or screws.
• Position the firestops on both sides of the hole previ-
ously cut and secure the firestops with nails or screws.
• The heat shields of the firestops MUST BE placed to-
wards the top of the hole.
• Continue the vent run through the firestops.

4. Install Firestops
For Horizontal Runs - Firestops are REQUIRED on both
sides of a combustible wall through which the vent passes.
NOTE: Model DVK-01TRD or SLK-01TRD does not need
an exterior firestop on an exterior combustible wall.
To install firestops for horizontal runs that pass through
either interior or exterior walls:
Cut a 12-inch by 12-inch (305 mm X 305 mm) hole through
the wall for D-series or a 10-inch by 10-inch (254 mm X 254
mm) hole for SL-D-series pipe. The center of the framing
hole is one (1) inch (25.4mm) above the center of the hori-
zontal vent pipe.
2. Continue Adding Vent Components
• Continue adding vent components, locking each succeed-
ing component into place.
• Ensure that each succeeding vent component is secure-
ly fitted and locked into the preceding component.
• 90° elbows may be installed and rotated to any point
around the preceding component’s vertical axis. If an el-
bow does not end up in a locked position with the pre-
ceding component, attach with a minimum of two (2)
sheet metal screws.

3. Install Support Brackets
For Horizontal Runs - The vent system must be supported
every five (5) feet of horizontal run by a horizontal pipe support.
To install support brackets for horizontal runs:
• Place the pipe supports around the vent pipe.
• Nail the pipe supports to the framing members.
