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 19.

2. Fasten the shield in place using the pilot holes provided
in the part. The shield should be oriented such that the
13 1/8 inch dimension (longest dimension) is running 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 20.
Figure 22. Adding Venting Components
• 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.
• 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 21). Cut the tabs as shown
and bend down. Secure the heat shield to the pipe main-
taining 3” to 4” between the pipe and shield.
