Positioning the Fireplace
Determine the exact position of the appliance 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 unit after the unit is moved into the final position.
Cutting the Hole
After the fireplace has been positioned in its permanent location,
cut the hole through the exterior wall of the house. This hole must
be 10 inches (254mm) high x 10-5/8 inches(270mm) wide with its
center line determined by the amount of vertical rise and horizontal
run of the termination. See Figure 53. When locating the hole the
bottom of the cap must be 12 inches (305mm) above the ground
level, and top of the cap must be no less than 18 inches (457mm)
below a combustible projection, and no closer than 9 inches (229mm)
to any wall running parallel to vent termination.
For installations requiring a vertical rise on the exterior of the
building, 14-inch and 36-inch tall Snorkel Terminations are available.
Follow the same installation procedures as used for standard
Horizontal Terminations. If the Snorkel Termination must be installed
below grade (i.e. basement applications, proper drainage must be
provided to prevent water from entering the Snorkel Termination.
See Figure 54. Do not attempt to enclose the Snorkel within the
wall or any other type of enclosure.

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 the venting system is installed below ground, protect
the vent with a window well that has proper drainage.
