Below-Grade Installation
When it is not possible to meet the required vent termination
clearances of 12 inches (305 millimeters) above grade level, a
snorkel kit is recommended. It allows installation depth down
to 7 inches (178 millimeters) below-grade level. The 7 inches
(178 millimeters) is measured from the center of the horizontal
vent pipe as it penetrates through the wall.
Observe the sidewall venting clearances. If the venting
system is installed below-grade, we recommend a window
well with adequate and proper drainage to be installed
around the termination area.
