Positioning the Fireplace
Position the fireplace so the direct-vent termination will be
centered (if possible) between two studs. Loosely fit up the
venting kit onto the fireplace. Ensure the vent pipe has proper
clearance for the wall thimbles.
Cutting the Hole
After the fireplace has been positioned, mark and cut the hole
through the exterior wall. This hole must be 13-inches (330 mm)
high x 10-5/8-inches (270 mm) wide with its center line determined
by the amount of vertical rise and horizontal run of the termination.
See Figure 40. Locate the hole so the bottom of the cap is a
minimum of 12-inches (305 mm) above the ground level. The top of
the cap must be at least 18-inches (457 mm) below a combustible
projection, and no closer than 9-inches (229 mm) 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-inches (305 mm) above grade level, a snorkel
kit is recommended. It allows installation depth down to 7-inches
(178 mm) below grade level. Measure the 7-inches (178 mm) from
the center of the horizontal vent pipe as it penetrates the wall.
Ensure the sidewall venting clearances are observed. For
venting system installed below ground, install a window
well with adequate and proper drainage around the
termination.
