bracket to the framing members with nails or screws.
3. Install Support Brackets
For Horizontal Runs - The vent system must be supported
every five (5) feet of horizontal run by a horizontal pipe support.
To install support brackets for horizontal runs:
• Place the pipe supports around the vent pipe.
• Nail the pipe supports to the framing members.

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 21.

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 22.
