INSTALLATION
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 12-5/8in high x 10-5/8in wide with its center line
determined by the amount of vertical rise and horizontal run of
the termination.
See Figure 30.
When locating the hole it must be
noted that the bottom of the cap must be 12in above the ground
level, and top of the cap must be no less than 18in below a
combustible projection, and no closer than 9in to any wall running
parallel to vent termination. Refer to “Below Grade Instatallation”
on page 25.
