Vertical Termination Configurations Figures 29 through 32 show four different configu- 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 reflect 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 specified in the second warning statement on page 11.
