TYPICAL HORIZONTAL VENT INSTALLATION
B. Frame exterior wall opening -
Locate the center of the vent outlet on
the exterior wall according to the dimen-
sions shown in Figure 12 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 20 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
21 on Page 14).
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.
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 previously
installed section in accordance with the require-
ments 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 21 on Page 14.
F. Install firestop/spacer at ceiling between
stories - Install a firestop/spacer (catalog no.
H2247 - Secure Vent; catalog no.H2249 - Secure
Flex) at the bottom side of the ceiling to the ceil-
ing joists. Route the vent sections through the
framed opening and secure the firestop/spacer
with 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 Section E on Page 15.
On the vertical run, support the venting system
every 8 feet (2.4m) above the fireplace vent out-
let 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 24 on Page 15.
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 required direction 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 25 on Page 15.
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 plumber’s tape.
See Figure 34. 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 replace 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.
Use a carpenter’s level to measure from a
constant surface and adjust the support straps
as necessary.
