1/12 to 7/12 Pitch Roof Terminal Kit GD110, 8/12 to 12/12
Roof Terminal Kit GD111, Flat Roof Terminal Kit GD112 or
Periscope Kit GD201 (for wall penetration below grade).
With fl exible venting, in conjunction with the various

PERISCOPE TERMINATION
Use the GD201 periscope kit to locate the air termination
above grade. The periscope must be installed so that when
fi nal grading is completed, the bottom air slot is located a
minimum of 12" above grade. The maximum allowable vent
length is 10 ft.

CORNER TERMINATION
The maximum vent length for a corner installation is 20" of
horizontal run, in addition to the 45° offset. In this case zero
rise is acceptable when using rigid. See FIGURE 5a. Flexible
venting must maintain a 6" rise. See FIGURE 5b.
