To attach and secure the termination to the last section of
horizontal ue:
• The rear ue heat shield MUST be placed one inch 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 inch
(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).
