D. Secure the Vent Sections
•Vertical runs of DVP pipe must be supported every 8 ft. (2.44 m) after the 25 ft. (7.62 m) maximum unsupported rise.
•Vertical runs of SLP pipe must be supported every 8 ft. (2.44 m).
•Horizontal sections must be supported every 5 feet (1.52 m).
•Vent supports or plumbers strap (spaced 120º apart) may be used to support. See Figures 8.8 and 8.9.
•Wall shield firestops may be used to provide horizontal support.
•SLP ceiling firestops have tabs that may be used to provide vertical support.
WARNING! Risk of Fire, Explosion or Asphyxiation! Improper support may allow vent to sag and separate. Use vent run supports and connect vent sections per in- stallation instructions. DO NOT allow vent to sag below connection point to appliance.

E. Disassemble Vent Sections
•Rotate either section (see Figure 8.10) so the seams on both pipe sections are aligned as shown in Figure 8.11.
•Pull carefully to separate the pieces of pipe.
