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 7.5.
•  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 7.6.

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, after any elbow, must be supported every 
5 ft. (1.52 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. See fi gures 7.7 and 7.8. 
• Wall shield fi restops may be used to provide horizontal 
support.
• 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.
