D. Assembly of Vent Sections (SL pipe)

WARNING

Fire Risk

Exhaust Fumes Risk

Impaired Performance of Appliance

•Ensure vent components are locked together correctly.

•Pipe may separate if not properly joined.

Attach the First Vent Component to 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 component 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 (see Figure 8.13). The vent pipe is now locked together.

•Slide the ceramic fiber pad over the first vent section and place it flush to the appliance. This will prevent cold air infiltration. High temp caulk may be used to hold the part in place. Continue to add vent components.

Continue Adding Vent Components

•Continue adding vent components, locking each suc- ceeding component into place.

•Ensure that each succeeding vent component is securely 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 elbow does not end up in a locked position with the preceding component, attach with a minimum of two (2) sheet metal screws.

Commercial, Multi-family (Multi-level exceeding two stories), & High-Rise Applications

For Installation into Commercial, multi-family (multi-level ex- ceeding two stories) or high-rise applications: All pipe joints must be sealed with high temperature silicone, including the slip section that connects directly to the horizontal termina- tion cap.

•Apply a bead of silicone sealant inside the female outer pipe joint prior to joining sections. See Figure 8.1

•Only outer pipes are sealed. Do not seal the inner flue. All unit collar, pipe, slip section, elbow and cap outer flues shall be sealed in this manner, unless otherwise stated.

Note: The end of the pipe sections with the lances/tabs on it will face toward the appliance.

WARNING

Fire Risk Explosion Risk

If slip section seals are broken during the removal of the termination cap, gas will leak and a fire or explosion may occur.

Do not break silicone seals on slip sections.

Note: When installing a vent system with an HRC termination cap, all pipe system joints shall be sealed using

ahigh-temperature silicone sealant.

•Apply a bead of silicone sealant inside the female outer pipe joint prior to joining sections.

•Only outer pipes are sealed, sealing the inner flue is not required. All unit collar, pipe, slip section, elbow and cap outer flues shall be sealed in this manner.

Figure 8.12 Adding Venting Components

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 Ver- tical Runs - The vent system must be supported every eight (8) feet (2.4 m) 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.

WARNING

Fire Risk. Explosion Risk. Combustion Fume Risk.

Use vent run supports per installation instructions.

Connect vent sections per installation instructions.

•Maintain all clearances to combustibles.

•Do NOT allow vent to sag below connection point to appliance.

•Maintain specified slope (if required). Improper support may allow vent to sag or separate.
