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- Figure 9 - Snorkel Termination 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
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.
