H. Flue Termination
For Horizontal Terminations using the SLP-TRAP
To attach and secure the termination to the last section of
horizontal flue:
• The rear flue heat shield MUST be placed 1 in. (25.4 mm)
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 (see Figure 10.16).
• The heat shield sections will overlap to match the wall
thickness (depth).
• If the wall thickness does not allow the required 1-1/2 in. (38
mm) 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 10.16).
