vENTING FIREpLACE - TOp (continued)
Below Grade Installation
When it is not possible to meet the required vent terminal clearances
of 12" (305mm) above grade level, a snorkel kit is recommended. See
Figures 41a and 41b . 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.
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.
