Service Notes
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 23 and 24)
After the fireplace has been positioned in its permanent location, the hole
through the exterior wall of the house can be cut. This hole needs to be 12
3/8" high x 10 3/8" width rectangle with its center line determined by the
amount of vertical arise and horizontal run of the termination. (See Figure
22) When locating the hole it must be noted that the bottom of the cap must
be 12" above the ground level, and top of the cap must be no less than 18"
below a combustible projection, and no closer than 9" to any wall running
parallel to vent termination. (See Figure 23)
