Installing Vent Pipe
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 8.1.
• Slide the gasket over the fi rst vent section and place it
fl ush to the appliance. This will prevent cold air infi ltration.
Caulk with a minimum of 300ºF 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
fi tted and locked into the preceding component.
Commercial, Multi-family (Multi-level exceeding two sto-
ries), 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 silicone with a minimum
of 300ºF continuous exposure rating, 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. See Figure 8.2
• 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.
Figure 8.1 Adding Venting Components
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
broken during removal of the termination cap, vent may
leak.
Note: Align seams to engage pipe,
then rotate counterclockwise to lock
