Figure 10.8 Securing Vertical Pipe Sections
Figure 10.9 Securing Horizontal Pipe Sections
E. Disassemble Vent Sections
• Rotate either section (see Figure 10.10) so the seams
on both pipe sections are aligned as shown in Figure
10.11.
Pull carefully to separate the pieces of pipe.
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 10.8 and 10.9.
• Wall shield restops may be used to provide horizontal
support.
• SLP ceiling restops 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.
