Install Instructions
Vent/Air System Installation
8
When cutting or correcting the shape of the
outer pipe, WEAR GLOVES. The ends of the
vent pipes can become very sharp when cut.
Adjustable Length Vent/Air System Pipe
The component piping and fittings (exclud-
ing the termination fittings and CCVPIP04)
are not design to be cut for custom lengths.
Cutting the piping or fittings to length may
compromise the vent seal causing potential
vent failure or leakage of flue gas resulting in
death, serious injury or
substantial injury.
1. An adjustable straight vent/air system pipe
length is available for applications that require
custom lengths.
2. The adjustable length vent/air system pipe is
adjustable from a minimum of 12” [30.5 cm] up
to a maximum of 16.5” [41.9 cm].
3. To adjust the length, firmly grab each end of the
pipe and twist together to shorten or twist apart
to lengthen.
WARNING
WARNING
Fire Stop Support Plate
The Fire Stop Support Plate must be used when the
vent/air system piping passes through any floors, ceil-
ings, enclosed chase or exterior walls. This plate can
be used for vertical or horizontal penetrations.
1. Prepare a 5-inch [12.7 cm] round or square open-
ing. Remove any insulation from the opening.
2. Secure the plate at the corners using the
screws provided. For exterior wall penetra-
tions, 2 plates are required, one on each side
of exterior wall. For interior wall/floor pen-
etrations, 1 plate is required.
3. Install the concentric pipe through the plate.
Secure the pipe to the Fire Stop Support Plate
using only the self-drilling screws provided,
through the plate tabs and into the concentric
pipes outer jacket.
The Support Plate provided in the Concentric
Vent/Air System Kit does not contain tabs for
securing the pipe to the plate, where as the
Fire Stop Support Plate does.
4. Seal around the support plate where
attached to exterior of building and around
pipe penetration, through the support plates
with silicone sealant.
Multiple Vent/Air System Terminations
For multiple appliance vent/air system installations
maintain a minimum of 12 inches [30.5 cm] from
centerlines as illustrated in Fig. 7.
