Venting and Chimneys
A . 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 7.2.
• 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 ºC) 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 high temperature
silicone (300 ºF (149 ºC) minimum continuous exposure
rating), including the slip section that connects directly to
the horizontal termination cap.
• Apply a bead of silicone sealant (300 ºF (149 ºC) mini-
mum continuous exposure rating) to the outside of
connecting joint after joining sections. See Figure 7.1.
OR
Apply aluminum foil tape (300 ºF (149 ºC) 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 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 remov-
ing termination cap from slip pipe. If slip section seals
are broken during removal of the termination cap, vent
could leak.
