KEEP CLEAR OF ALL OBSTRUCTIONS.

COLD CLIMATE INSULATION

For cold climate installations, seal all cracks
around your appliance with noncombustible
material and wherever cold air could enter
the room. It is especially important to insulate
outside chase cavity between studs and under
floor on which appliance rests, if floor is above
ground level. Gas line holes and other openings
should be caulked or stuffed with unfaced
fiberglass insulation.

If the fireplace is being installed on a cement
slab in cold climates, a sheet of plywood or
other raised platform can be placed underneath
to prevent cold transfer to the fireplace and
into the room. It also helps to sheetrock inside
surfaces and tape for maximum air tightness
and caulk firestops.

NOTE: Attic insulation shield (H3908, see Page 10) must be
installed when blown or loose-fill insulation is used, and is
required for all attic installations.

Shelf Height

To provide for the lowest possible shelf surface, the venting attached to
the top vent should be routed in a way to minimize obstructions to the
space above the appliance. Do not insulate the space between the ap-
pliance and the area above it (see Figure 7). The minimum height from
the base of the appliance to the underside of combustible materials used
to construct a utility shelf in this fashion is shown in Figure 7.

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 face
(black sheet metal). Never allow combustible materials to be positioned

in front of or overlapping the appliance face. See Figure 9 and Figure
51 on Page 30.

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 8. Mantels constructed of non­combustible materials may be installed at any height above the appliance
opening. Minimum clearance requirements include any projections such
as shelves, window sills, mantels, etc. above the appliance.

NOTE: We recommend the use of high temperature paint (rated 175° F
or higher) on the underside of the mantel.

Minimum clearance requirements include any projections such as
shelves,window sills, mantels, etc. above the appliance.

Framing

Step 1. FRAMING

Frame these appliances as illustrated in Figure
11 on Page 12, unless the appliance is to be
installed in a corner. See Figure 12 on Page
13 for corner framing installations. All framing

details must allow for a minimum clearance to
combustible framing members as shown in
Table 5 on Page 10.

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.

A header heat shiled is taped to the top of the
fireplace. Slide the heat shield into the framing
and attach the heat shield using the screws in
the standoff (see Figure 10).

The fireplace should be secured to the side
framing members using the unit's nailing
flanges—one top and bottom on each side of
the fireplace front (see Figure 10). Use 8d nails
or their equivalent.

Step 2. ROUTING GAS LINE

Route a 1/2" (13 mm) gas line along the inside
of the right side framing as shown in Figure

13. 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" shutoff
valve. (See Step 6 on Page 24).

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 25.

Figure 13

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/
CGA-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. We recommend
that a qualified individual such as a 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" shutoff
valve (see Figure 36 on Page 25).

• 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 25).

• 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.

• It is recommended to install a sediment trap
in the supply line as close as possible to the
appliance (see Figure 36 on Page 25).

• Check with local building official for local
code requirements.

IMPORTANT: If propane is used, be aware that
if tank size is too small (i.e. under 100 lbs, if
this is the only gas appliance in the dwelling.
Ref. NPFA 58), there may be loss of pressure,
resulting in insufficient fuel delivery (which
can result in sooting, severe delayed ignition
or other malfunctions). Any damage resulting
from an improper installation, such as this,
is not covered under the limited warranty.

General Information
These instructions should be used as a guide-

line and do not supersede local codes in any
way. Install vent according to local codes,
these instructions, the current National Fuel
Gas Code (ANSI-Z223.1) in the USA or the
current standards of CAN/CGA-B149.1 and

-B149.2 in Canada.
Ensure clearances are in accordance with

local installation codes and the requirements
of the gas supplier.

Dégagement conforme aux codes
d'installation locaux et aux exigences du
foumisseunde gaz.

Use only approved venting components.
See Approved Vent Components on
Page 4.

These fireplaces must be vented directly
to the outside.

The vent system may not service multiple
appliances, and must never be connected to a
flue serving a separate solid fuel burning ap­pliance. The vent pipe is tested to be run inside
an enclosing 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.

Installation of Vent Restrictor

A vent restrictor may be needed with this
appliance. The restrictor is installed in the
appliance top flue outlet as shown in Figure 14,

For vertical venting from 6 feet to 12 feet or
more, from the top of the fireplace to the top
of the termination, the installation of a vent
restrictor is required.

If necessary, install a vent restrictor in the
appliance flue outlet as shown in Figure 14. The
vent restrictor is held in place by friction, only.

NOTE: The restrictor is included within the
firebox.

The vertical vent system terminates through
the roof. The minimum vent height above the
roof and/or adjacent walls is specified in ANSI
Z223.1—latest edition (In Canada, the current
CAN/CGA-B149.1 installation code) by major
building codes. Always consult your local
codes for specific requirements. A general
guide to follow is the Gas Vent Rule (refer to

Figure 4 on Page 8).

Vertical (Straight) Installation

(Figure 15)

Determine the number of straight vent 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 (see Tables on this page and Page
32—Vent Sections). Plan the vent lengths so
that a joint does not occur at the intersection of
ceiling or roof joists. Refer to the Vent Section
Length Chart.

Vertical (Offset) Installation

Analyze the vent routing and determine the
quantities of vent sections and number of elbows
required. Refer to Vertical Vent Figures and
Tables on Page 18 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 15 for an aid in select-
ing length combinations. Elbows are available
in 90° and 45° configurations. Refer to Figure
20 on Page 17 for the SV8 E45 and SV8 E90
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 3" (76 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
dime nsions, about this center mark (Figure 16).

®

SV8 direct-vent system components
are unitized concentric pipe components
featuring positive twist lock connections (see

Figure 17).

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 the dimple (four places) of the
upper vent section with the opening
of the locking incline channel on the
lower vent section or appliance col­lar. Twist vent component clockwise
to engage and seal until arrow and

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 17). 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 17.

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. Remember to maintain 1" (25 mm)

clearance to combustibles, framing members,
and attic or ceiling insulation when running
vertical chimney sections. Attic insulation
shield (H3908) is required and may be used to
help maintain the clearances indicated here.
See installation accessories on Page 32. The

gap between the vent pipe and a vertical firestop
can be sealed with non-combustible caulking.

E. Support the 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 by utilizing field pro-

Storm
Collar

vided support straps (conventional plumber's
tape). Secure the plumber's tape to the framing
members with nails or screws. Strap the tape
around the vent, securing the ends of the tape
to the framing. If desired, sheet metal screws
#6 x 1/2" length may be used to secure the
support straps to the vent pipe. See Figure 18

on Page 16.

F. Change vent direction to horizontal/inclined
run—At transition from or to a horizontal/

inclined run, install the SV8 E45 and SV8 E90
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 17 on Page 16 and Figure 19.

K. Install the vertical termination—The final

step involves installation of the Vertical Termina­tion. Extend the vent sections to the height as
shown in the "Vertical vent termination section"
on Page 8. The SV8VTR Vertical Termination
(Figure 22) can be installed in the exact same
fashion as any other Secure Vent® section. 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.

G. Continue installation of horizontal/inclined
sections—Continue with the 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 19, Figure 26. It is very important
that the horizontal/inclined run be maintained in

a straight (no dips), slightly elevated plane. The
recommended incline is approximately 1/4" per
foot (20 mm per meter) horizontal, in a direction
away from the fireplace. The rise per foot run
ratios that are smaller are acceptable all the way
down to at or near level. Use a carpenter’s level
to measure from a constant surface and adjust
the support straps as necessary.

It is important to maintain the required clear­ances 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.

H. Frame roof opening—Identify location for
vent at the roof. Cut and/or frame opening per
Roof Framing Chart (Figure 20).

I. Install the 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 21). 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 the storm collar—Install the storm
collar, supplied with the flashing, over the vent/
flashing joint (see Figure 21). 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.

If the vent system extends more than 5 feet (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.
