HORIZONTAL (OUTSIDE WALL)
TERMINATION SYSTEM
See
Figure 32
, and
Figures 35
to

and
their associated Horizontal Vent Table which
illustrates the horizontal venting configura-
tions that are allowed to be used with these
appliances. Secure Vent pipe applications are
shown in these figures; Secure Flex pipe may
also be used (see
Page 24
)
. A Horizontal Vent
Table summarizes each system’s minimum and
maximum vertical and horizontal length values
that can be used to design and install the vent
components in a variety of applications.
Both of these horizontal vent systems terminate
through an outside wall. Building Codes limit or
prohibit terminating in specific areas. Refer to
Figure 6
on
Page 6
for location guidelines.
Secure Vent SV4.5 direct vent system compo-
nents are unitized concentric pipe components
featuring positive twist lock connection, (
refer
to
Figure 20
on
Page 14
). All of the appli-
ances 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.
Plan the vent lengths so that a section joint
does not occur within the space defined by
ceiling joists, roof rafters or wall studs. Make
allowances for elbows as indicated in
Figure
23
on
Page 15
.
Maintain a minimum " (25 mm) clearance to
combustibles on the vertical sections. Clear-
ances for the horizontal runs are; 3" (76 mm)
on top, " (25 mm) on sides, and " (25 mm)
at the bottom.
B. Frame exterior wall opening -
Locate the center of the vent outlet on the ex-
terior wall according to the dimensions shown
in
Figure 13A (See-Through Models)
on
Page
9 and Figure 13B (Peninsula Models)
on
Page 10
.
Cut and/or frame an opening, 10-1/2" x 12 1/8"
(267 mm x 308 mm) 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, 10-1/2" x 10-1/2" (267 mm x 267
mm) inside dimensions, about this center (refer
to
Figure 19
on
Page 14
).
D. Attach vent components to appliance - To
attach a vent component to the appliance collar,
align the dimpled end over the collar, adjust-
ing the radial alignment until the four locking
dimples are aligned with the inlets of the four
incline channels on the collar (
refer to
Figure
20
on
Page 14
).
