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). The small leg in the shield
rests on top of the flue to properly space it from the
pipe section (see Figure 22).
