SPECIAL VENT INSTALLATIONS
GD36 BGD36
The maximum vent length
for a corner installation
is 24", where only 6" of
vertical rise is used. All
corner installations require
a minimum 6" rise. See
FIGURE 4a. The maximum vent length for
a corner installation is 20" of
horizontal run, in addition to
the 45° offset. In this case
0" rise is acceptable when
using rigid. See FIGURE
4b. Flexible venting must
maintain a 6" rise. See
FIGURE 4a.
