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). Do not back fill around snorkel termination.
