VENTING INSTALLATION

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 19 and 20). Snorkel kit SVKBK is also available (see page 17). Follow the same installation procedures used for standard horizontal terminations. If installing the snorkel termination below grade (base- ment applications), you must provide proper drainage to prevent water from entering the snorkel termination (see Figure 20). Do not back fill around the snorkel termination.

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 fittings. (All connec- tions must be sealed with high tempera- ture silicone sealant as specified in the sec- ond warning statement on page 10.) Push the pipe sections together and twist one sec- tion clockwise approximately one-quarter turn until the sections are fully locked. See Figure 21, page 12. Note: Horizontal runs of vent must be supported every three feet. Use wall straps for this purpose.
