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.
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.
TYPICAL BASEMENT INSTALLATION
Figure 23
Examples of possible venting systems using one 90° elbow. Eight
feet is listed as minimum vertical vent run with 20 feet of maximum
horizontal vent run. Vertical dimensions are based on centerline to
centerline of pipe. Horizontal dimensions are based on centerline
of pipe to end of termination.
Figure 24
Examples of possible venting systems using two 90° elbows. V
is listed as minimum vertical dimensions and H1 + H2 is listed as
total of maximum horizontal dimensions. The maximum vertical
and horizontal distances for two 90° elbows as shown in Figure
20 is 20 feet.
Attention: Refer to Figure 22 for additional venting requirements.
