B. Assemble Slip Sections
• Slide the inner
fl
ue of the slip section into the inner
fl
ue
of the pipe section and the outer
fl
ue of the slip section
over the outer
fl
ue of the pipe section. See Figure 7.6.
• Slide together to the desired length.
• Continue adding pipe as necessary following instructions
in “Assembling Pipe Sections.”
NOTICE:
If slip section is too long, the inner and outer
fl
ues of the slip section can be cut to the desired length.
NOTICE:
When installing a vent system with an HRC
termination cap, all pipe system joints shall be sealed using
a silicone sealant with a minimum of 300ºF continuous
exposure rating.
• Apply a bead of silicone sealant inside the female outer
pipe joint prior to joining sections.
• Only outer pipes are sealed, sealing the inner
fl
ue is not
required.
• All unit collar, pipe, slip section, elbow and cap outer
fl
ues shall be sealed.
• Maintain a 1-1/2 in. (38 mm) overlap between the slip
section and the pipe section.
• Secure the pipe and slip section with two screws no
longer than 1/2 in. (13 mm), using the pilot holes in the
slip section. See Figure 7.7.

C. 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 7.8
and 7.9.
• 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 could 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.
