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 (Figures 21)
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 12" (305mm) high x 10" (254mm) wide with its center line
determined by the amount of vertical rise and horizontal run of the
termination. See Figure 21. When locating the hole it must be noted
that the bottom of the cap must be 12" (305mm) above the ground
level, and top of the cap must be no less than 18" (457mm) below
a combustible projection, and no closer than 9" (229mm) to any
wall running parallel to vent termination. See Figure 22.
