B. Continue Adding Vent Components
To Install the Heat Shield:
1. Determine if the heat shield is required. Do so by measuring
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
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 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 maintaining 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
succeeding component into place.
• Ensure that each succeeding vent component is securely
fi tted and locked into the preceding component in the
vent system.
• 90º elbows may be installed and rotated to any point
around the preceding component’s vertical axis. If an
elbow does not end up in a locked position with the
preceding component, attach with a minimum of two (2)
sheet metal screws.
C. Install Support Brackets
Refer to Cinch Pipe and Termination Cap installation in-
structions.
