Below Grade Installation
Empire recommends installing a snorkel kit when it is not
possible to meet the required vent terminal clearances of
12
inches
(305 mm) above grade level. A snorkel kit allows an
installation depth down to 7 inches (178 mm) below grade level.
The 7
inches
(178 mm) is measured from the center of the
horizontal vent pipe as it penetrates through the wall.
Ensure the sidewall venting clearances are observed.
Empire recommends installing a window well with adequate
and proper drainage around the termination area if the
venting system is installed below ground.
