D. Secure the Vent Sections
• Vertical runs originating off the top of the appliance, with
no offsets, must be supported every 8 ft. (2.44 m) after
the maximum allowed 25 ft. (7.62 m) of unsupported rise.
• Vertical runs originating off the rear of the appliance, or
after any elbow, must be supported every 8 ft. (2.44 m).
• Horizontal runs must be supported every 5 feet (1.52
m).
• Vent supports or plumbers strap (spaced 120º apart)
may be used to support vent sections. See Figures 10.8
and 10.9.
• Wall shield
fi
restops may be used to provide horizontal
support to vent sections.
• SLP ceiling
fi
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
