C. Flue Termination

For Horizontal Terminations - To attach and secure the termination to the last section of horizontal flue:

The rear flue heat shield MUST be placed one inch above the top of the flue between the wall shield and the base of the termination cap.

One section of the heat shield is attached to the wall shield. The other is attached to the termination cap in the same manner.

The heat shield sections will overlap to match the wall thickness (depth).

If the wall thickness does not allow the required 1-1/2 inch heat shield overlap, an extended heat shield must be used. The extended heat shield will need to be cut to the thickness of the wall and be attached to the wall shield.

The small leg in the shield rests on top of the flue to properly space it from the pipe section (see Figure 1.26).
