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.

• 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 maintain-

• Continue adding vent components, locking each suc-
ceeding component into place.
• Ensure that each succeeding vent component is securely
fi tted 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
elbow does not end up in a locked position with the
preceding component, attach with a minimum of two (2)
sheet metal screws.
