G. Install Vertical Termination Cap
• Attach the vertical termination cap by sliding the inner
collar of the cap into the inner
fl
ue of the pipe section
while placing the outer collar of the cap over the outer
fl
ue of the pipe section.
• Secure the cap by driving three self-tapping screws
(supplied) through the pilot holes in the outer collar of
the cap into the outer
fl
ue of the pipe (see Figure 10.17).
Important Notice:
Heat shields may not be
fi
eld constructed.
H. Heat Shield Requirements for Horizontal
Termination
WARNING! Risk of Fire!
To prevent overheating and
fi
re,
heat shields must extend through the entire wall thick-
ness.
•
DO NOT
remove the heat shields attached to the wall
shield
fi
restop and the horizontal termination cap.
• Heat shields must overlap 1-1/2 in. (38 mm) mini-
mum.
There are two sections of the heat shield. One section
is factory-attached to the wall shield
fi
restop. The other
section is factory-attached to the cap. If the wall thickness
does not allow the required 1-1/2 in. (38 mm) heat shield
overlap when installed, an extended heat shield must be
used.
• If the wall thickness is less than 4 in./102 mm (DVP), the
heat shields on the cap and wall shield
fi
restop must be
trimmed. A minimum 1-1/2 in. (38 mm) overlap MUST
be maintained.
• Use an extended heat shield if the
fi
nished wall thickness
is greater than 7-1/4 in. (184 mm).
• The extended heat shield may need to be cut to length
maintaining suf
fi
cient length for a 1-1/2 in. (38 mm)
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. Refer to vent components diagrams in the
back of this manual.
• Rest the small leg on the extended heat shield on top
of the pipe section to properly space it from the pipe
section.
Note:
When using termination caps with factory-supplied
heat shield attached, no additional wall shield
fi
restop is
required on the exterior side of a combustible wall.
I. Install Horizontal Termination Cap
WARNING! Risk of Fire!
The telescoping
fl
ue section of
the termination cap MUST be used when connecting vent.
• 1-1/2 (38 mm) minimum overlap of
fl
ue telescoping
section is required.
Failure to maintain overlap may cause overheating and
fi
re.
• Vent termination 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.
• When installing a horizontal termination cap, follow
the cap location guidelines as prescribed by current
ANSI Z223.1
and
CAN/CGA-B149
installation codes
and refer to Section 6 of this manual.
CAUTION! Risk of Burns!
Local codes may require in-
stallation of a cap shield to prevent anything or anyone
from touching the hot cap.
NOTICE:
For certain exposures which require superior
resistance to wind-driven rain penetration, a
fl
ashing kit is
available. When penetrating a brick wall, a brick extension
kit is available for framing the brick.
