SL-D and SL-Flex Series Venting Only:
1.Attach the First Vent Component to the Starting Collars
To attach the first vent component to the starting collars of the appliance:
•Lock the vent components into place by sliding the con- centric pipe sections with four (4) equally spaced interior beads into the appliance 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
•Slide the ceramic fiber pad over the first vent section and place it flush to the appliance (see Figure 1). This will prevent cold air infiltration. High temp caulk may be used to hold the part in place. Continue to add vent compo- nents.
If the installation is for a termination cap attached directly to the appliance, skip to the sections, Install Firestops and Vent Termination.
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.
For Vertical Runs - The vent system must be supported every eight (8) feet (2.4m) above the appliance 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.
