B. Installing Vent Components
1. Attach the First Vent Component to the
Starting Collars
To attach the first vent component to the starting collars
of the fireplace:
• Apply a 3/8 inch (9.5mm) bead of stove cement around
the fireplace inner vent starting collar.
• Lock the vent components into place by sliding the con-
centric pipe sections with four (4) equally spaced interi-
or beads into the fireplace collar or previously installed com-
ponent end with four (4) equally spaced indented sections.
• When the internal beads of each outer pipe line up, ro-
tate the pipe section clockwise about one-quarter (1/4)
turn. The vent pipe is now locked together.

2. Continue Adding Vent Components
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.
Figure 13. Adding Venting Components
•
Continue adding vent components, locking each suc-
ceeding component into place.
•
Ensure that each succeeding vent component is secure-
ly fitted and locked into the preceding component in the
vent system.
•
90° elbows may be installed and rotated to any point
around the preceding component’s vertical axis. If an
elbow does not end up in a locked position with the
preceding component, attach with a minimum of two (2)
sheet metal screws.
