Important Notice: Heat shields may not be ¿ eld constructed.
I. Heat Shield Requirements for Horizontal
Termination
WARNING! Risk of Fire! To prevent overheating and ¿ re,
heat shields must extend through the entire wall thick-
ness.
• DO NOT remove the heat shields attached to the
wall shield ¿ restop 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 ¿ restop. The other
section is factory-attached to the cap. See Figure 10.21.
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 in./102 mm the heat
shields on the cap and wall shield ¿ restop must to be
trimmed. A minimum 1-1/2 in. (38 mm) overlap MUST
be maintained.
• Use an extended heat shield if the ¿ nished wall thickness
is greater than 7-1/4 in. (184 mm).
• The extended heat shield may need to be cut to length
maintaining suf¿ 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.
H. Install Vertical Termination Cap
• Attach the vertical termination cap by sliding the inner
collar of the cap into the inner À ue of the pipe section
while placing the outer collar of the cap over the outer
À ue of the pipe section.
• Secure the cap by driving three self-tapping screws
(supplied) through the pilot holes in the outer collar of the
cap into the outer À ue of the pipe (see Figure 10.19).
