VENTING FIREPLACE - TOP (CONT'D)
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. Assemble the vent pipes on the unit
after it 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 (254 millimeters) high x 10-5/8 inches (270 millimeters)
wide with its center line determined by the amount of vertical rise
and horizontal run of the termination. See Figure 57. When locating
the hole, the bottom of the must be 12 inches (305 millimeters)
above the ground level, and top of the cap must be no less than
18 inches (457 millimeters) below a combustible projection, and at
least 9 inches (229 millimeters) to any wall running parallel to vent
termination.
