Position the Fireplace
If possible, position the fireplace so the direct vent termination will
be centered 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.
Cut the Hole
The hole through the exterior wall of the house can be cut after
the fireplace has been positioned in its permanent location. This
hole must be 11 inches high x 9-1/2 inches wide with its center
line determined by the amount of vertical rise and horizontal run
of the termination. See Figure 34 on page 21. The bottom of the
cap must be 12 inches above the ground level, and top of the cap
must be no less than 18 inches below a combustible projection,
and no closer than 9 inches to any wall running parallel to vent
termination. See Figure 35.
