B. Installing Vent Components
Venting Out the Top Vent
The glass must be taken off again for positioning the logs
when the unit is finally installed in place and finished around
it. Re-install the glass door. Attach vent system to the top
starting collars.
1. Attach the First Vent Component to the
Starting Collars
To attach the first vent component to the starting collars of
the fireplace:
Refer to Cinch Pipe (DVP) and Termination Cap installation
instructions.
2. Continue Adding Vent Components
• Continue adding vent components snap-locking, locking
each succeeding component into place.
• Ensure that each succeeding vent component is secure-
ly fitted and locked into the preceding component in the
vent system. Securing pipe sections with a maximum of
two screws is recommended.
• 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
Refer to Cinch Pipe and Termination Cap installation
instructions.
4. Install Firestops
For Horizontal Runs - Firestops are REQUIRED on both
sides of a combustible wall through which the vent passes.
NOTE: Model DVP-TRAP 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 10-inch by 12-inch (254mm X 305mm) hole through
the wall.
NOTE: The center of the hole is one (1) inch (25.4mm)
above the center of the horizontal vent pipe.
• 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.
