A. Assemble Vent Sections
To attach the fi rst 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 10.1.
• Slide the gasket over the fi rst vent section and place
it flush to the appliance. This will prevent cold air
infi ltration. High temperature caulk 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
fi tted and locked into the preceding component.

WARNING! Risk of Fire or Explosion! DO NOT break
silicone seals on slip sections. Use care when removing
termination cap from slip pipe. If slip section seals are bro-
ken during removal of the termination cap, vent may leak.
Commercial, Multi-family (Multi-level exceeding
two stories), or High-Rise Applications
For Installation into a commercial, multi-family (multi-level
exceeding two stories) or high-rise applications: All outer
pipe joints must be sealed with high temperature silicone,
including the slip section that connects directly to the
horizontal termination cap.
• Apply a bead of silicone sealant inside the female outer
pipe joint prior to joining sections.
• Only outer pipes need to be sealed. All unit collar, pipe,
slip section, elbow and cap outer fl ues shall be sealed
in this manner, unless otherwise stated.

with two screws which must not exceed 1/2 in. (13 mm)
in length. Use the pilot holes. Pipe could separate if not
properly joined.

NOTICE: When installing a vent system with an HRC
termination cap, all pipe system joints shall be sealed using
a high temperature silicone sealant.
• 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.
• 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.
• 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 10.3.
• 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 11.2.
• Slide together to the desired length.
