Assemble Vent Sections
(SLP Only)
To attach the first vent component to the starting collars
of the appliance:
• Lock the vent components into place by sliding the pipe
section onto the collar.
• Align the seam of the pipe and seam of collar to allow
engagement. Rotate the vent component to lock into
place. Use this procedure for all vent components. See
Figure 7.5.
• Slide the gasket over the first vent section and place it
flush to the appliance. This will prevent cold air infiltration.
Caulk with a minimum of 300 ºF (149 °C) continuous
exposure rating may be used to hold the part in place.
• Continue adding vent components, locking each
succeeding component into place.
• Ensure that each succeeding vent component is securely
fitted and locked into the preceding component.
Required Commercial, Multi-family (Multi-level exceeding
two stories), or High-Rise Applications
All outer pipe joints must be sealed with 100% silicone
(300 ºF (149 °C) minimum continuous exposure rating),
including the slip section that connects directly to the hori-
zontal termination cap.
• Apply a bead of silicone sealant (300 ºF (149 °C) mini-
mum continuous exposure rating) inside the female
outer pipe joint prior to joining sections. See Figure
7.1.
OR
Apply a bead of silicone sealant (300 ºF (149 °C) mini-
mum continuous exposure rating) to the outside of
connecting joint after joining sections
OR
Apply aluminum foil tape (300 ºF (149 °C) minimum
continuous exposure rating) to the outside of connect-
ing joint after joining sections. On horizontal pipe runs,
it is recommended that the tape seam is positioned on
the bottom side of the vent pipe.
• Only outer pipes need to be sealed. All appliance collar,
pipe, slip section, elbow and cap outer flues shall be
sealed in this manner, unless otherwise stated.
Figure 7.5 Adding Venting Components
WARNING! Risk of Fire or Explosion! DO NOT
break
silicone seals on slip sections. Use care when remov-
ing termination cap from slip pipe. If slip section seals
are broken during removal of the termination cap, vent
could leak.
Note: Align seams to engage pipe,
then rotate counterclockwise to lock
B. Assemble Slip Sections
• Slide the inner flue of the slip section into the inner flue
of the pipe section and the outer flue of the slip section
over the outer flue of the pipe section. See Figure 7.6.
• Slide together to the desired length.

NOTICE:
When installing a vent system with an HRC
termination cap, all pipe system joints shall be sealed
using a high temperature silicone sealant (300 ºF (149 °C)
minimum continuous exposure rating).
•
Apply a bead of silicone sealant (300 ºF (149 °C)
minimum continuous exposure rating) inside the female
outer pipe joint prior to joining sections.
•
Only outer pipes are sealed, sealing the inner flue is not
required.
•
All appliance collar, pipe, slip section, elbow and cap
outer flues shall be sealed.
• Continue adding pipe as necessary following instructions
in “Assembling Pipe Sections.”
NOTICE:
If slip section is too long, the inner and outer flues
of the slip section can be cut to the desired length.
• 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.
