D. Disassemble Vent Sections
• Rotate either section (see Figure 10.9) so the seams
on both pipe sections are aligned as shown in
Figure 10.10.
• Pull carefully to separate the pieces of pipe.
C. 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.
• Horizontal sections of vent must be supported every 5
ft. (1.52 m) with a vent support or plumber’s strap.
• Wall shield fi restops may be used to provide horizontal
support.
• Vent support or plumber’s strap (spaced 120° apart)
may be used for support. See Figures 10.9 and 10.10.
WARNING! Risk of Fire, Explosion or Asphyxi-
ation! Improper support may allow vent to sag and
separate. Use vent run supports and connect vent
sections per installation instructions. DO NOT allow
vent to sag below connection point to appliance.
