Heat shields may not be field constructed.
L. Heat Shield Requirements for Horizontal
Termination
For all horizontally vented appliances, a heat shield MUST
be placed 2.5 cm above the top of the flue pipe between the
wall shield firestop and the base of the termination cap.
There are two sections of the heat shield. One section
is factory-attached to the wall shield firestop. The other
section is factory-attached to the cap. See Figure 47.
If the wall thickness does not allow the required 4 cm heat
shield overlap when installed, an extended heat shield
must be used.
warNiNG! risk of fire!
To prevent overheating and fire,
heat shields must extend through the entire wall thickness.
Heat shields must overlap 4 cm minimum.
•
DO NOT
remove the heat shields attached to the wall
shield firestop and the horizontal termination cap (shown
in Figure 47).
• If the wall thickness is less than 10 cm (DVP) or 11 cm
(SLP), the heat shields on the cap and wall shield firestop
must to be trimmed. A minimum 4 cm overlap MUST be
maintained.
• Use an extended heat shield if the finished wall thickness
is greater than 18.4 cm.
• The extended heat shield may need to be cut to length
maintaining sufficient length for a 4 cm overlap between
heat shields.
• Attach the extended heat shield to either of the existing
heat shields using the screws supplied with the extended
heat shield.
• Rest the small leg on the extended heat shield on top
of the pipe section to properly space it from the pipe
section.
Install Horizontal Termination Cap
warNiNG! risk of fire!
The telescoping flue section of
the termination cap MUST be used when connecting flue
pipe.
• 38 cm) minimum overlap of flue telescoping section
is required.
Failure to maintain overlap may cause overheating and
fire.
• Termination caps must not be recessed in the wall. Siding
may be brought to the edge of the cap base.
• Flash and seal as appropriate for siding material at
outside edges of cap.
cauTiON! risk of burns!
Local codes may require in-
stallation of a cap shield to prevent anything or anyone
from touching the hot cap.

Note:
When using termination caps with factory-supplied
heat shield attached, no additional wall shield firestop is
required on the exterior side of a combustible wall.
NOTice:
For certain exposures which require superior
resistance to wind-driven rain penetration, a flashing kit and
HRC caps are available. When penetrating a brick wall, a
brick extension kit is available for framing the brick.
