I. Install Heat Shields and Horizontal Termi-
nation Cap
Important Notice: Heat shields may not be fi eld constructed.
WARNING! Risk of Fire! To prevent overheating and fi re,
heat shields must extend through the entire wall thick-
ness.
• DO NOT remove the heat shields attached to the
wall shield fi restop and the horizontal termination
cap (shown in Figure 10.26).
• Heat shields must overlap 1-1/2 in. (38 mm) mini-
mum.
There are two sections of the heat shield. One section
is factory-attached to the wall shield fi restop. The other
section is factory-attached to the cap. See Figure 10.17.
If the wall thickness does not allow the required 1-1/2 in.
(38 mm) heat shield overlap when installed, an extended
heat shield must be used.
• If the wall thickness is less than 4-3/8 in./111 mm, the
heat shields on the cap and wall shield fi restop must to
be trimmed. A minimum 1-1/2 in. (38 mm) overlap MUST
be maintained.
• Use an extended heat shield if the fi nished wall thickness
is greater than 7-1/4 in. (184 mm).
• The extended heat shield may need to be cut to length
maintaining suffi cient length for a 1-1/2 in. (38 mm)
overlap between heat shields.
• Attach the extended heat shield to either of the existing
heat shields using the screws supplied with the extended
heat shield. Refer to “Vent Components Diagrams” in
the back of this manual.
• Rest the small leg on the extended heat shield on top
of the pipe section to properly space it from the pipe
section.
