BELOW GRADE SIDEWALL VENTING WITH POLYPROPYLENE – Snorkel style
2” or 3” non-concentric side wall vent termination, snorkel style.
VENTING GUIDELINES WHEN USING TWO PIPES (SNORKEL STYLE)
1. Use a properly installed window well (no window present) or equivalently constructed well with adequate drainage
2. Wall penetration must be at least 5” above the bottom of the window well.
3. Vertical rise must be limited to 4 feet maximum between elbows (see figure below); longer runs may require a
chimney chase and/or insulation on the vent to prevent condensation and freezing.
4. Vertical Separation: The exhaust vent must be above the air inlet between 12” and 15”.
5. Horizontal Separation: The horizontal distance between the air inlet and the exhaust vent must be a minimum of 4”
center to center.
