nailing flanges on each side of unit and any adjacent screw heads.

The appliance should be mounted on a fully supported base extending
the full width and depth of the unit. The appliance may be located on
or near conventional construction materials; however, if installed on
combustible materials, such as carpeting, vinyl tile, etc., a metal or wood
barrier covering the entire bottom surface must be used.

Min. Height of Combustible Enclosure

To provide for the lowest possible combustible enclosure (or shelf)
surface, the venting should be routed in a way to minimize obstructions
to the space above the appliance. Do not insulate the space between the
appliance and the area above it (see Figure 8).

Wall Finishes / Surrounds / Mantels

Note: Combustible wall finish materials and/or surround materials must
not be allowed to encroach the area defined by the appliance front faces
(black sheet metal). Never allow combustible materials to be positioned
in front of or overlapping the appliance face. See Pages 33 and 34.

Non-combustible materials, such as surrounds and other appliance trim,
may be installed on the appliance front face with these exceptions: they
must not cover any portion of the removable glass panel.

Vertical installation clearances to combustible mantels vary according
to the depth of the mantel (see Figure 9). Mantels constructed of non­combustible materials may be installed at any height above the appliance
opening.

for a minimum clearance to combustible fram­ing members as shown in Table 5 and Figures
8–10 on Page 11.

If the appliance is to be elevated above floor
level, a solid continuous platform must be
constructed below the appliance.

Headers may be in direct contact with the
appliance top spacers but must not be sup­ported by them or notched to fit around them.
All construction above the appliance must be
self-supporting, DO NOT use the appliance for
structural support.

Secure the fireplace to the side framing mem­bers using the unit's nailing flanges — one
top and bottom on each side of the fireplace
front (see Figure 13). Use 8d nails or their
equivalent.

Step 2. ROUTE GAS LINE

NOTICE: For indoor/outdoor installations,

the CONTROL SIDE of the fireplace must
be installed on the INDOOR side.

Route a 1/2" (13 mm) gas line along the inside
of the right side framing as shown in Figures 14
and 15. Gas lines must be routed, constructed
and made of materials that are in strict accor­dance with local codes and regulations.

All appliances are factory-equipped with a
flexible gas line connector and 1/2-inch shutoff
valve (see Step 6 on Page 26).

The incoming gas line should be piped into
the valve compartment and connected in one
of the two methods as shown in Figure 36 on
Page 26.

Proper Sizing of Gas Line

Properly size and route the gas supply line
from the supply regulator to the area where the
appliance is to be installed per requirements
outlined in the National Fuel Gas Code, NFPA
54 - latest edition (USA) or CAN/CSA-B149.1

- latest edition (Canada).
Never use galvanized or plastic pipe. Refer to

Table 6 for proper sizing of the gas supply line,
if black iron pipe is being used. Gas lines must
be routed, constructed and made of materials
that are in strict accordance with local codes
and regulations.

IMPORTANT: It is critical that a licensed
installer perform this step strictly per
NFPA.

We recommend that a qualified, licensed
plumber or gas fitter be hired to correctly size
and route the gas supply line to the appliance.
Installing a gas supply line from the fuel supply
to the appliance involves numerous consider­ations of materials, protection, sizing, loca­tions, controls, pressure, sediment, and more.
Certainly no one unfamiliar and unqualified
should attempt sizing or installing gas piping.

Notes:

• All appliances are factory-equipped with
a flexible gas line connector and 1/2-inch
shutoff valve (see Figure 36 on Page 26).

• See Massachusetts Requirements on Page
6 for additional requirements for installa­tions in the state of Massachusetts in the
USA.

• The gas supply line should not be connected
to the appliance until Step 6 (Page 26).

• A pipe joint compound rated for gas should
be used on the threaded joints. Ensure

propane-resistant compounds are used in
propane applications. Be very careful that

the pipe compound does not get inside the
pipe.

• Sediment Trap: It is recommended to install
a sediment trap in the supply line as close as
possible to the appliance (see Figure 36 on
Page 26). Appliances using propane should
have a sediment trap at the base of the tank.

• Check with local building official for local
code requirements (such as whether below­grade penetrations of the gas line allowed,
etc.).

directly to the outside.

Vent Restrictor Kit

Vent Restrictor Assembly for
Horizontal Termination Systems

For systems with horizontal
termination, use only the vent
restrictor base.

The vent system may not service multiple ap­pliances and must never be connected to a flue
serving a solid fuel burning appliance.

The vent pipe is tested to be run inside an
enclosed wall (such as a chase). There is no
requirement for inspection openings in the en­closing wall at any of the joints in the vent pipe.

Vent Restrictor Assembly and
Installation

All vent systems require installation of a vent
restrictor. A vent restrictor kit is provided with
the fireplace (packaged inside the firebox) and
includes one base, two wings, and four screws
(see Figure 16A).

1. Assemble the vent restrictor components

according to the type of termination and
length of vent run, as shown in Figures 16B
and 16C.

2. Install the vent restrictor in the appliance
top flue outlet, as shown in Figure 16D. The

vent restrictor is held in place by friction
only.

Vent Restrictor Assembly for Vertical Termination Systems

For systems with vertical termination, use the four provided
screws to attach the two wings to the base in the applicable
position based on length of vertical run, as shown below.

Assembly for vertical termination with 6–10 ft vertical runs:

Note: When possible, install the vent

restrictor through the top of the appliance
vent outlet BEFORE installing the vent
system. (It is possible to install the vent
restrictor from inside the firebox after vent
system installation; however, doing so
requires removing the firebox baffle.)

Vent Termination
(Vertical or Horizontal)

With the appliance secured in framing,
determine whether to terminate the venting
vertically (through the roof) or horizontally
(through the wall).

• For Vertical (Roof) Termination Systems,
see Pages 17–20.

• For Horizontal (Wall) Termination Systems,
see Pages 21–24.

Vertical (Roof) Termination
Systems

This section includes configurations for vertical
(roof) termination systems with either straight
vertical venting (see below and Page 20) and
offset vertical venting (see Pages 18–20).
Secure Vent™ rigid vent pipe and termination
components are shown in the figures.

The tables on Page 20 summarize each sys­tem’s minimum and maximum vertical and
horizontal length values.

For vertical (roof) termination, the minimum
vent height above the roof and/or adjacent
walls is specified in ANSI Z223.1, latest edi­tion (in Canada, the current CAN/CSA-B149.1
installation code) and by major building
codes. Always consult your local codes for
specific requirements. A general guide to
follow is the Gas Vent Rule (see Figure 3B

on Page 8).

Vertical Termination System
with Straight Vertical Venting

Note: If not already done, install the pro­vided vent restrictor before proceeding
(see Page 16).

Determine the number of straight vent sec­tions required. Available straight vent sec­tions (and their effective lengths) are listed
in Table 7, below. See Page 36 for all venting
components.

Plan the vent lengths so a joint does not occur
at the intersection of ceiling or roof joists.
Refer to the “VENT SECTION LENGTHS”
charts at right.

Vertical Termination System
with Offset Vertical Venting

Note: If not already done, install the pro­vided vent restrictor before proceeding
(see Page 16).

Analyze the vent routing and determine the
quantities of vent sections and number of
elbows required. Refer to Vertical Termination
System Figures and Tables on Page 20 to
select the type of vertical installation desired.
Vent sections are available in net lengths of
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). Refer to the Vent Section Length
Chart on Page 17 for an aid in selecting length
combinations. Elbows are available in 90° and
45° configurations. See Figure 21 on Page 19
for the SV8E45 and SV8E90 elbow dimensional
specifications.

Where required, a telescopic vent section
(SV8LA) may be used to provide the installer
with an option in installing in tight and confined
spaces or where the vent run made up of fixed
length pieces develops a joint in a undesirable
location, or will not build up to the required
length. The SV8LA Telescopic Vent Section has
an effective length of from 1-1/2" (38 mm) to
6-3/4" (171 mm). The SV8LA is fitted with a
dimpled end (identical to a normal vent section
component) and a plain end with 3 pilot holes.
Slip the dimpled end over the locking channel
end of a standard SV8 vent component the
required distance and secure with three screws.

Maintain a minimum 1" (25 mm) clearance
to combustible materials for all vertical ele­ments. Clearances for all horizontal elements
are 4" (102 mm) on top, 1" (25 mm) on sides
and 1" (25 mm) on the bottom.

A. Frame ceiling opening.

Use a plumb line from the ceiling above the
appliance to locate center of the vertical run.
Cut and/or frame an opening, 13" x 13" (330
mm x 330 mm) inside dimensions, about this
center mark (Figure 18).

B. Attach vent components to appliance.
Secure Vent™ SV8 direct-vent system compo-

nents are unitized concentric pipe components
featuring positive twist lock connections (see
Figure 19).

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.

Align four dimples in upper vent
section with inlets of four locking
incline channels on lower vent
section or appliance collar.

Twist upper vent section clockwise

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 inlet of
the four inclined channels on the collar (refer
to Figure 19). 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 without the need for sealant or
screws. If desired, a #6 x 1/2" screw may be
used at the joint, but it is not required, as the
pipe will securely lock when twisted.

C. Attach vent components to each other.

Other vent sections may be added to the pre­viously installed section in accordance with
the requirements of the vertical vent figures
and tables.

To add another vent component to a length of
vent run, align the dimpled end 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 19.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

D. Install firestop/spacer at ceiling.
When using Secure Vent, use SV8BF 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. When running vertical chimney

sections, remember to maintain 1" (25 mm)
clearance to combustibles, framing mem­bers, and attic or ceiling insulation. Attic
insulation shield (H3908) is required and
may be used to help maintain the clearances
indicated here. See installation accessories
on Page 36. The gap between the vent pipe
and a vertical firestop can be sealed with
non-combustible caulking.

E. Support vertical vent run sections.

Note: Proper venting support is very im­portant. The weight of the vent must not be
supported by the fireplace in any degree.

Support the vertical portion of the venting
system every 8 feet (2.4 m) above the fireplace
vent outlet.

One method of support is conventional
plumber’s tape (not provided). Secure the
plumber’s tape to the framing members with
nails or screws.

Loop the plumber’s tape around the vent,
securing the ends of the tape to the framing.
If desired, use #6 x 1/2" sheet metal screws
to secure the support straps to the vent pipe.
See Figure 20.

F. Change vent direction to horizontal/
inclined run.

At any transition to or from a horizontal/
inclined run, install the elbows (SV8E45,
SV8E90; see Figure 21) 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,
to avoid the possibility of unlocking any pre­viously connected vent section (see Figures

19 and 21).

K. Install vertical termination.

The final step involves installation of the verti­cal termination. Extend the vent sections to the
height as shown in “Vertical Vent Termination
Clearances” on Page 8.

The vertical termination (Figure 24) installs
in the same manner as other Secure Vent™
sections. Align the termination over the end of
the previously installed section, adjusting the
radial alignment until the four locking dimples
of the termination are aligned with the inlets of
the four incline channels of the last vent section.
Push the termination down until it fully engages,
then twist the termination clockwise, running
the dimples down and along the incline chan­nels until they seat at the end of the channels.

Figure 21

G. Continue installation of horizontal/
inclined sections.

Continue with installation of the straight vent
sections in horizontal/inclined run as de­scribed in Step C. Install support straps every
3 ft (914 mm) along horizontal/inclined vent
runs using conventional plumber’s tape (see
Page 21, Figure 28).

NOTICE: It is important to install

horizontal runs on a steady, (i.e., no
“dips”), slightly positive incline of
approximately 1/4 inch 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.

Note: It is important to maintain the required
clearances to combustibles: 1" (25 mm) at
all sides for all vertical runs; and 4" (102
mm) at the top, 1" (25 mm) at sides, and
1" (25 mm) at the bottom for all horizontal/
inclined runs.

I. Install roof flashing.

Extend the vent sections through the roof
structure. Install the roof flashing over the
vent section and position such that the vent
column rises vertically (use carpenters level)
(Figure 23 ). Nail along perimeter to secure
flashing or adjust roofing to overlap the flash­ing edges at top and sides only and trim where
necessary. Seal the top and both sides of the
flashing with waterproof caulking.

J. Install storm collar.

Install the storm collar, supplied with the
flashing, over the vent/flashing joint (see
Figure 23). Loosen the storm collar screw.
Slide collar down until it meets the top of the
flashing. Tighten the adjusting screw. Apply
non-combustible caulking or mastic around
the circumference of the joint to provide a
water tight seal.

Figure 24

If the vent system extends more than 5 ft (1.5
m) above the roof flashing, stabilizers may be
necessary.

Additional screws may be used at section joints
for added stability.

Guide wires may be attached to the joint for ad­ditional support on multiple joint configurations.
