VENTING FIREPLACE - TOP (CONT’D)
POSITIONING THE FIREPLACE
Determine the exact position of the fireplace so the direct-vent
termination will be centered (if possible) between two studs. This
will avoid any extra framing. All vent kit pipes should be assembled
on the fireplace after the fireplace is moved into the final position.
CUTTING THE HOLE
After the fireplace has been positioned in its permanent location,
the hole through the exterior wall can be cut. This hole must be 11
inch high x 9-1/8 inch wide with its center line determined by the
amount of vertical rise and horizontal run of the termination.
See
Figures 39 and 42.
When locating the hole it must be noted that
the bottom of the cap must be minimum of 12 inch (305mm) above
the ground level, and top of the cap must be no less than 18 inch
(457mm) below a combustible projection, and no closer than 9 inch
(229mm) to any wall running parallel to vent termination.

BELOW GRADE INSTALLATION
When it is not possible to meet the required vent termination
clearances of 12 inch (305 mm) above grade level, a snorkel
kit is recommended. It allows installation depth down to 7 inch
(178 mm) below grade level. The 7 inch (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. If
venting system is installed below ground, we recommend
a window well with adequate and proper drainage to be
installed around the termination area.
