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 10 and 11). Snorkel kit SVK is also available (see page 15). Follow the same installation procedures as used for stan- dard horizontal terminations. If install- ing the snorkel termination below grade (basement applications), you must pro- vide proper drainage to prevent water from entering the snorkel termination (see Figure 11). 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 fit- tings. (All connections must be sealed with high temperature silicone sealant as specified in the second warning on page 7.) Push the pipe sections together and twist one section clockwise approxi- mately one-quarter turn until the sections are fully locked. See Figure 12, page 9. Note: Horizontal runs of vent must be supported every three feet. Use wall straps for this purpose.

Flexible vent pipe must be installed with spacer springs every 12". See Figure 12, page 9. All connections must be clamped tightly and sealed with high temperature silicone sealant as specified in the sec- ond warning on page 7.
