Important Notice:
Heat shields may not be field constructed.
WARNING! Risk of Fire!
To prevent overheating and fire,
heat shields must extend through the entire wall thick-
ness.
•
DO NOT
remove the heat shields attached to the
wall shield firestop and the horizontal termination
cap.
• 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 firestop. The other
section is factory-attached to the cap. See Figure 0..
If the wall thickness does not allow the required -/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 firestop must to
be trimmed. A minimum -/2 in. (8 mm) overlap MUST
be maintained.
• Use an extended heat shield if the finished wall thickness
is greater than 7-/4 in. (84 mm).
• The extended heat shield may need to be cut to length
maintaining sufficient 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.
