VENTING FIREPLACE - TOP (continued)
Positioning the Fireplace
Determine the exact position of the appliance so the direct vent
termination will be centered (if possible) between two (2) 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,
the hole through the exterior wall of the house can be cut. This hole
must be 10-in (254mm) high x 10-5/8-in (270mm) wide with its center
line determined by the amount of vertical rise and horizontal run
of the termination.
See Figure 46.
When locating the hole it must
be noted that the bottom of the must be 12-in (305mm) above the
ground level, and top of the cap must be no less than 18-in (457mm)
below a combustible projection, and no closer than 9-in (229mm)
to any wall running parallel to vent termination.
