Horizontal (wall) Termination

Systems
This section includes configurations for hori-
zontal venting systems with horizonal termina-
tion (terminates through an outside wall) (see
Figures 32–34 on Pages 26–27).
The tables on Pages 26 and 27 summarize each
system's minimum and maximum vertical and
horizontal length values.
NOTE: Building codes limit or prohibit hori-
zontal termination in specific areas. For loca-
tion guidelines, see Figure 6 on Page 12.
Secure Vent pipe applications are shown in
®
the illustrations. Secure Vent SV8 direct-vent
system components are unitized concentric
pipe components featuring positive twist-lock
connection (see Figure 20 on Page 21). 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.
See Page 20 for a list of available straight vent
sections and their effective lengths (Table 7),
as well as "VENT SECTION LENGTHS" charts.
See Page 35 for a list of all approved venting
components.
Plan the vent lengths so that a joint does not
occur at the intersection of ceiling or roof
joists. Make allowances for elbows as indi-
cated in Figure 22 on Page 22.
Maintain a minimum 1" (25 mm) clearance
to combustibles on the vertical sections.
Clearances for horizontal runs are 4" (102
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 di men -
sions shown in Figure 13 on Page 16.
Cut and/or frame an opening 16" x 13" (406
mm x 330 mm) inside dimensions, with
10" above center and 7" below 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, 13" x
13" (330 mm x 330 mm) inside dimensions,
about this center (see Figure 19 on Page 21).
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 (see
Figure 20 on Page 21).

Push the vent component against the collar
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. The unitized design of the Secure
Vent components will engage and seal both the
inner and outer pipe elements with the same
procedure. Sealant and securing screws are
not required.
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 21.
F. Install firestop/spacer at ceiling.
When using Secure Vent, use SV8BF vertical
firestop/spacer at ceiling joists. 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.
Remember to maintain 1" (25 mm) clearance
to combustibles, framing members, and attic
or ceiling insulation when running vertical
chimney sections.

G. Support the vertical run sections.
See Step E on Page 21.
On the vertical run, support the venting system
every 8 ft (2.4 m) above the fireplace vent outlet
with field provided support straps (Plumber's
tape). Attach the straps to the vent pipe and
secure to the framing members with nails or
screws (see Figure 21 on Page 21).
H. Change vent direction.
At transition from or to a horizontal/inclined
run, install the SV8E45 and SV8E90 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 required direc-
tion of the next vent run element. Twist elbow
sections in a clockwise direction only so as
to avoid the possibility of unlocking any of
the previously connected vent sections (see
Figure 20 on Page 21).
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 3 feet
(1914 mm) along horizontal/inclined vent runs
using conventional plumber's tape.
See Figure 29.
NOTICE: It is important to install
horizontal runs on a steady, (i.e.,
no "dips"), slightly positive incline of
approximately 1/4" rise-per-foot (20
millimeters rise-per-meter) horizontal,
in a direction away from the fireplace.
(Slightly smaller rise-per-foot run ratios
are acceptable.) Use a carpenter's level
to measure from a constant surface, and
adjust support straps as necessary.
