allowable a2 and e dimensions to be determined by consult-
ing the venting graph and horizontal venting termination
examples on pages 22 and 23.
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. 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 12-5/8 inches high x 10-5/8 inches wide with its location
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 12 inches minimum above the
ground level, or average snowfall, and top of the cap must be no
less than 18 inches below a combustible projection and no closer
than 9 inches to any wall running parallel to vent termination.
Below Grade installation
When it is not possible to meet the required vent termination clearances
of 12 inches above grade level, a snorkel kit is recommended. It
allows installation depth down to 7 inches below grade level. The
7 inches is measured from the center of the horizontal vent pipe as
it penetrates through the wall.
ensure the sidewall venting clearances are observed. if venting
system is installed below ground, we recommend a window
well with adequate and proper drainage to be installed around
the termination area.
