TYPICAL HORIZONTAL VENT INSTALLATION
Figure 32
Secure Vent SV4.5 direct vent system compo-
nents are unitized concentric pipe components
featuring positive twist lock connection, (
refer to
Figure 19
on page 11). All of the appliances
covered in this document are fitted with collars
having locking inclined channels. The dimpled
end of the vent components fit over the appliance
collar to create the positive twist lock connection.
A. Plan the vent run -
Analyze the vent routing and determine the
types and quantities of sections required
4 ¹⁄₂" (114 mm), 10 ¹⁄₂" (267 mm), 22 ¹⁄₂" (572
mm), 34 ¹⁄₂" (876 mm) and 46 ¹⁄₂" (1181 mm)
net section lengths are available. Make allow-
ances for elbows as indicated in
Figure 19
.
Maintain a minimum 1" (25 mm) clearance to
combustibles on the vertical sections. Clearances
for the horizontal runs are; 3" (76 mm) on top, 1"
(25 mm) on sides, and 1" (25 mm) at the bottom.
B. Frame exterior wall opening -
Locate the center of the vent outlet on the
exterior wall according to the dimensions shown
in
Figure 9
on page 7. Cut and/or frame an
opening, 10¹⁄₂" x 12¹⁄₈" (267 mm x 308mm)
inside dimensions, about this center.
C. Frame ceiling opening - If the vertical
route is to penetrate a ceiling, use plumb line
to locate the center above the appliance. Cut
and/or frame an opening, 10¹⁄₂" x 10¹⁄₂" (267
mm x 267 mm) inside dimensions, about this
center (refer to
Figure 18
on page 11 ).
D. Attach vent components to appliance - To attach
a vent component to the appliance collar, align the
dimpled end over the collar, adjusting the radial
alignment until the four locking dimples are aligned
with the inlets of the four incline channels on the
collar (refer to
Figure 19
on page 11 ).
G. Support the vertical run sections -
See Section E on page 11.
The unitized design of the Secure Vent compo-
nents will engage and seal both the inner and outer
pipe elements with the same procedure. Sealant
and securing screws are not required.
Note: An elbow may also be attached to the
appliance collar. Attach in the same manner as
you would a vent section.
E. Attach vent components to each other -
Other vent sections may be added to the previ-
ously installed section in accordance with the
requirements of the vent tables. To add another
vent component to a length of vent run, align the
dimpled end of the component over the inclined
channel end of the previously installed section,
adjusting the radial alignment until the four
locking dimples are aligned with the inlets of the
four incline channels of the previous section.
Push the vent component against the previous
section until it fully engages, then twist the
component clockwise running the dimples down
and along the incline channels until they seat at
the end of the channels.This seating position is
indicated by the alignment of the arrow and
dimple as shown in
Figure 20 on page 11.
F. Install firestop/spacer at ceiling -
When using Secure Vent, use SV4.5BF firestop/
spacer at ceiling joists; when using Secure Flex, use
SF4.5BF firestop/spacer. If there is living space
above the ceiling level, the firestop/ spacer must be
installed on the bottom side of the ceiling. If attic
space is above the ceiling, the firestop/ spacer must
be installed on the top side of the joist. Route the
vent sections through the framed opening and
secure the firestop/spacer with 8d nails or other
appropriate fasteners at each corner.
I. Continue installation of horizontal/inclined
sections - Continue with the installation of the
straight vent sections in horizontal/inclined run
as described in Step E. Install support straps
every 5 ft. (1.52 m) along horizontal/inclined
vent runs using conventional plumbers tape.
See
Figure 32.
It is very important that the
horizontal/inclined run be maintained in a
straight (no dips) and recommended to be in
a slightly elevated plane, in a direction away
from the fireplace of
¹⁄₄" rise per foot (20 mm
per meter) which is ideal, though rise per foot
run ratios that are smaller are acceptable all the
way down to at or near level.
It is important to maintain the required clear-
ances to combustibles: 1" (25 mm) at all sides
for all vertical runs; and 3" (76 mm) at the top,
1" (25 mm) at sides, and 1" (25 mm) at the
bottom for all horizontal/inclined runs
J. Assemble vent run to exterior wall - If not
previously measured, locate the center of the
vent at the exterior wall. Prepare an opening as
described in Step B. Assemble the vent system
to point where the terminus of the last section is
within 5 in. (127 mm) to 9¹⁄₄ in. (235 mm)
inboard of the exterior surface to which the
termination is to be attached, see
Figure 34
.
Both of these horizontal vent systems terminate
through an outside wall. Building Codes limit or
prohibit terminating in specific areas. Refer to
Figure 8
on page 6 for location guidelines.
Figure 32, and Figures 36 to 43 on pages 17,
18 and 19
and their associated Horizontal Vent
Table illustrate the various horizontal venting
configurations that are possible for use with
these appliances. Secure Vent pipe applica-
tions are shown in these figures; Secure Flex
pipe may also be used. A Horizontal Vent Table
summarizes each systems minimum and maxi-
mum vertical and horizontal length values that
can be used to design and install the vent
components in a variety of applications.
HORIZONTAL (OUTSIDE WALL)
TERMINATION SYSTEM
H. Change vent direction - At transition from
or to a horizontal/inclined run, install the
SV4.5E45 and SV4.5E90 elbows in the same
manner as the straight vent sections. The
elbows feature a twist section to allow them
to be routed about the center axis of their
initial collar section to align with the re-
quired direction of the next vent run ele-
ment. Twist elbow sections in a clockwise
direction only so as to avoid the possiblity
of unlocking any of the previously con-
nected vent sections. See
Figure 22
.
Remember to maintain 1" (25 mm) clear-
ance to combustibles, framing members,
and attic or ceiling insulation when running
vertical chimney sections.
Push the vent component against the collar
until it fully engages, then twist the compo-
nent clockwise, running the dimples down
and along the incline channels until they seat
at the end of the channels.
