To Install the Heat Shield:
1. Determine if the heat shield is required. Do so by mea-
suring the vertical distance between the top horizontal
surface of the elbow to any combustible surface above.
If the distance is more than 4 inches, the heat shield is
NOT required. If it is 4 inches or less, the heat shield IS
REQUIRED. Install per the following steps. See Figure 4.5.
CORRECT INCORRECT
2. Fasten the shield in place using the four pilot holes pro-
vided in the part. The shield should be oriented such that
the 13 1/8 inch dimension (longest dimension) is run-
ning in the same direction the elbow is pointing. The
shield should be centered directly above the elbow, and
positioned so that it creates a 1/2 inch airspace between
the shield and the combustible surface. See Figure 4.6.

• If the combustible materials are not in place at the time
of install the elbow heat shield may be screwed to the
exhaust pipe (see Figure 4.7). Cut the tabs as shown
and bend down. Secure the heat shield to the pipe main-
taining 3 inch to 4 inch between the pipe and shield.
Refer to Cinch Pipe and Termination Cap installation in-
structions.
• Continue adding vent components, locking each succeed-
ing component into place.
• Ensure that each succeeding vent component is secure-
ly fitted and locked into the preceding component in the
vent system.
• 90° elbows may be installed and rotated to any point
around the preceding component’s vertical axis. If an el-
bow does not end up in a locked position with the pre-
ceding component, attach with a minimum of two (2)
sheet metal screws.
