(over 12" horizontal pipe)

• Basement installation where one foot clearance from ground to

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 install-
