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 termina-

tion below grade, you must provide proper drainage to prevent water from entering snorkel termination (see Figure 16). Do not back fill

around snorkel termination.
