Continued
Figures 29 through 32 show four different congu-
rations for vertical termination. These minimum
vertical rises are based on horizontal runs with a
minimum of 1/4" upwards pitch per foot ad do
not reect constraints on a vertical system with
45° or greater offset.
Any offset pitch of 45° or less must be considered
horizontal and sized within the maximum allow-
able lengths listed in the following examples. All
connections must be sealed with high temperature
silicone sealant as specied in the second warning
statement on page 11.
