Installing Vent Pipe (SLP Pipe)
Figure 10.2 High Temperature Silicone Sealant
A. Assemble Vent Sections
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 10.1.
• Slide the gasket over the first vent section and place it
flush to the appliance. This will prevent cold air infiltration.
Caulk with 149
ºC minimum 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.
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
(149 ºC minimum 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 10.2
• Only outer pipes need to be sealed. All unit collar, pipe,
slip section, elbow and cap outer flues shall be sealed in
this manner, unless
otherwise stated.
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.
