INSTALLATION FOR HORIZONTAL TERMINATION

1.Determine the route your horizontal venting will take. Note: The location of the horizontal vent termination on the exterior wall must meet all local and national building codes and must not be easily blocked or obstructed.

WARNING: Do not recess vent terminal into a wall or siding.

Snorkel terminations are available for terminations requiring a vertical rise on the exterior of the building (see Figures 9 and 10). Follow the same installation procedures as used for standard horizon- tal terminations. If installing the snor- kel termination below grade (basement applications), you must provide proper drainage to prevent water from entering the snorkel termination (see Figure 10). Do not back fill around the snorkel ter- mination.

2.Rigid vent pipes and fittings have spe- cial twist-lock connections. Assemble the desired combination of pipe and el- bows to the appliance adaptor with pipe seams oriented towards the wall or floor.

Twist-lock Procedure: The female ends of the pipes and fittings have four locking lugs (indentations). These lugs will slide straight into matching slots on the male ends of adjacent pipes and fit- tings. (All connections must be sealed with high temperature silicone sealant as specified in the second warning state- ment on page 7.) Push the pipe sections together and twist one section clockwise approximately one-quarter turn until the sections are fully locked. See Figure 11, page 9. Note: Horizontal runs of vent must be supported every three feet. Use wall straps for this purpose.
