Page 23: Below Grade Installation
VENT INSTALLATION BELOW GRADE INSTALLATIONS When it is not possible to meet the required vent terminal clearances of 12" above grade level, a snorkel kit is recommended. It allows installation depth down to 7" (178mm) below grade level. The 7" (178mm) is measured from the center of the horizontal vent pipe as it penetrates through the wall. -
