Damper Collar Extension & Extended Heat
Shields:
• If the wall thickness does not allow the required 1-1/2 in.
(38 mm) overlap when installed, an extended heat shield
and damper collar extension must be used. Refer to vent
components diagrams in the back of this manual.
• Use a damper collar extension and extended heat shield
if the finished wall thickness is greater than 7 in. (178
mm). Note: The damper collar extension and extended
heat shield may need to be cut to length, maintaining
sufficient length for a 1-1/2 in. (38 mm) overlap.
• Attach the damper collar extension to the damper collar
on the termination cap and attach with minimum of (3)
screws. See Figure 7.10.
Figure 7.10 Damper and Heat Shield Extension
• 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.
I
mportant Notice: Heat shields may not be field
constructed.
WARNING! Risk of Fire! The telescoping flue section of
the wall shield MUST be used when connecting vent.
• 1-1/2 (38 mm) minimum overlap of flue telescoping
section is required. Failure to maintain overlap could
cause overheating and fire.
• 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 4 of this manual.
CAUTION! Risk of Burns! Local codes may require
installation 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 flashing
kit is available. When penetrating a brick wall, a brick
extension kit is available for framing the brick.
Installing the Termination Cap
Note:
Proper termination clearances to windows,
doors, electrical service, etc. must be maintained as
shown in Section 4 of this manual.
Note: The appliance, wire harness, vent, wall shields
and firestops must be located, supported, and secured
prior to mounting the termination cap. See Figure 7.11.
Wire Harness pass-through hole should be sealed with a
100% silicone sealant (300°F minimum continuous expo
-
sure rated).
Figure 7.11
• Insert the lanced end of the female slip section
through the wall shield and connect to unit collar, on
minimum vent installations, or the last section of vent
pipe for longer vent runs. See Figure 7.12.
