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