B. Continue Adding Vent Components

WARNING

Fire Risk.

Installation of this appliance may require the use of heat shield 385-290 above the ﬁrst 900 elbow in the venting system.

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.

•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.

SHIELD

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.

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 ﬁtted 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.
