• The termination kit should pass through the wall restops
from the exterior of the building.
• Adjust the termination cap to its nal exterior position on
the building and interlock the ue sections.
WARNING! Risk of Fire! the termination cap must be
positioned so that the arrow is pointing up.
• Use a high-temperature sealant gasket to seal between

H. Flue Termination
For Horizontal Terminations using the SLP-TRAP
To attach and secure the termination to the last section of
horizontal ue:
• The rear ue heat shield MUST be placed 1 in. (25.4
mm) above the top of the ue 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 10.17).
• 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 ue to
properly space it from the pipe section (see Figure 10.17).
