Each figure includes a chart with critical minimum and maximum dimensions which MUST be met. IMPORTANT: If using a venting configuration of only horizontal venting with no vertical run, a 1/4" rise for every 12" of run toward the termination is required.
Venting Installation instructions Continued SNORKEL TERMINATION INSTALLATION Recommended Applications: • Installations requiring a vertical rise on building exterior • Any installation using snorkel termination to achieve one foot above ground Snorkel terminations are available for installations requiring a vertical rise on the exterior of the building. If installing snorkel termination below grade, you must provide proper drainage to prevent water from entering snorkel termination (see Figure 16).
Venting Installation instructions Continued installation for vertical termination Note: Vertical restrictor must be installed in all vertical installations. 1. 2. Determine the route your vertical venting will take. If ceiling joists, roof rafters, or other framing will obstruct the venting system, consider an offset (see Figure 19) to avoid cutting load bearing members.
