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 open-
ings 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.

LOCATION
In selecting the location, the aesthetic and
functional use of the appliance are primary
concerns. However, vent system routing to
the exterior and access to the fuel supply are
also important.
Due to high temperatures, the appliance
should be located out of traffic and away from
furniture and draperies (Figure 2).
Enraisondestempératuresélevées,l’appareil
devrait être installé dans un endroit où il y a
peu de circulation et loin du mobilier et des
tentures (Figure 2).
The location should also be free of electrical,
plumbing or other heating/air conditioning
ducting.
These direct-vent appliances are uniquely
suited for installations requiring a utility shelf
positioned directly above the fireplace. Utility
shelveslikethese are commonly used for locat-
ing television sets and decorative plants.
Be aware that this is a heat producing ap-
pliance. Objects placed above the unit are
exposed to elevated temperatures.
Do not insulate the space between the ap-
pliance and the area above it (see Figure 8
on Page 8).
Theminimum height from the baseof the appli-
ance to the underside of combustible materials
used to construct a utility shelf in this fashion
is shown in Figure 8 on Page 8.
The appliance should be mounted on a fully
supported base extending the full width and
depth of the unit. The appliance may be located
onornearconventional constructionmaterials.

Hearth Extension - A hearth extension is not required with this appliance. If a hearth extension is used,
do not block the lower control compartment access door. Any hearth extension used is for appearance
only and does not have to conform to standard hearth extension installation requirements.
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 and back faces (black sheet metal). Never allow combustible
materials to be positioned in front of or overlapping the appliance front and back faces. See Figure
58 on Page 32.
Non-combustible materials, such as surrounds and other appliance trim, may be installed on the
appliance front and back faces with the following exception: If the optional radiant panels are
installed, the non-combustible material may cover any portion of the top radiant panel or the air
gaps surrounding the top radiant panel down to the top edge of eyebrow hood.
The material must
NOT cover any portion of the glass door or louvered panels.
Vertical installation clearances to combustible mantels vary according to the depth of the mantel. See
Figure 6. Mantels constructed of non-combustible materials may be installed at any height above the
appliance opening; however, do not allow anything to hang below the hood.
NOTE: We recommend the use of high temperature paint (rated 175° F or higher) on the under-
side of the mantel.

Warnings.
Step 1. FRAMING
FrametheseappliancesasillustratedinFigures
11 or 12. All framing details must allow for a
minimum clearance to combustible framing
members as shown in Table 5 on Page 8.
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 sup-
ported 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.
Side Nailing Flanges
The fireplace should be secured to the fram-
ing at the side(s) of the appliance using the
factory-provided nailing flanges. Install the 8
nailing flanges as shown in Figure 10 using the
existing screws. Position the fireplace within
the framing. When required, the tabs may be
bent 90 degrees by hand or with the assistance
of a hammer. Use wood screws to secure the
nailing flanges to the framing. See Table 5 on
Page 8 for clearances of framing members
to cabinet parts. The nailing flange itself can
directly contact framing.
Floor Nailing Tabs - Secure the fireplace to the
floor as shown in Figure 10.

Figure 13 - ROUTE GAS LINE
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 sup-
ply 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
applianceinvolvesnumerousconsiderationsof
materials,protection,sizing,locations,controls,
pressure,sediment, andmore.Certainlynoone
unfamiliarandunqualifiedshouldattemptsizing
or installing gas piping.
Notes:
• All appliances are factory-equipped with a
flexiblegaslineconnector and1/2inch shutoff
valve (see Figure 47 on Page 28).
• See Massachusetts Requirements on Page
4for 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 28).
• 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 47). Appliances using
Propane should have a sediment trap at the
base of the tank.
• Check with local building ofcial for local code
requirements(i.e.arebelowgradepenetrations
of the gas line allowed?, etc).
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.
Step 2. ROUTING GAS LINE
Routea gaslinealongtheinside oftheright side

Installation of Vent Restrictor
(Top Vent Installations with Vertical Terminations Only)
A vent restrictor (provided) may be needed with this appliance. If needed,
install the vent restrictor (provided) in the appliance top flue outlet as
shown in Figure 16 when vertically terminating the vent system above
the roof. It may be installed either from inside or outside the appliance,
in the inner fireplace collar. It is press-fitted in place.
Note: The restrictor is included within the firebox.

Step 3. INSTALL THE VENT SYSTEM
General Information
These instructions should be used as a guideline and do not supersede
local codes in any way. Install venting according to local codes, these
instructions, the current National Fuel Gas Code (ANSI-Z223.1) in the
USA or the current standards of CAN/CSA-B149.1 in Canada.
Ensure clearances are in accordance with local installation codes and
the requirements of the gas supplier.
Dégagementconformeaux codesd'installationlocauxetaux exigences
du foumisseunde gaz.
Use only approved venting components. See Approved Vent
Components on Page 2.
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 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.
REMOVE VENT SEAL CAP
(From the vent that will be used only)
Top Vent - See Figure 14 and Side Vent - See Figure 15
Preparing the Appliance Vent Collar
Each of the appliances' two vent collars are sealed with a seal cap which
must be removed from the vent collar being used. Refer to Figure 14
for top vent installations and Figure 15 for side vent installations and
the following steps to prepare the appropriate collar for use.
From the vent collar being used, remove the two screws securing the
vent seal cap. Twist the cap counterclockwise. Pull it away from the
appliance and discard, along with the piece of insulation.

VERTICAL TERMINATION SYSTEMS (ROOF)
See Figure 17 and Figures 28 to 32 (Pages 18
and19) andtheirassociatedVerticalVentTables
illustratetheverticalventingconfigurationsthat
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 25. A Vertical Vent Table sum-
marizeseachsystem’sminimumandmaximum
vertical and horizontal length values that can be
used to design and install the vent components
in a variety of applications.
Both these vertical vent systems terminate
through the roof. The minimum vent height
above the roof and/or adjacent walls is speci-
fied in ANSI Z223.1-(latest edition) (In Canada,
the current CAN/CSA-B149.1 installation code)
by major building codes. Always consult your
localcodes forspecificrequirements. A general
guide to follow is the Gas Vent Rule (refer to
Figure 3B on Page 6).
A vent restrictor will need to be installed when
vertical termination is used. See Installation of
Vent Restrictor on Page 13 for guidelines.
Vertical (Straight) Installation
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 avail-
able (see Table 7 and Page 34 - Item 3). It is
recommended that you plan the vent lengths
so that a section joint does not occur within the
space defined by ceiling joists or roof rafters.
Refer to the Vent Section Length Chart.

Vertical (Offset) Installation
Analyze the vent routing and determine the
number of vent sections and elbows required.
Refer to Vertical Vent Figures and Tables on
Pages 18 and 19 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
LengthChartsonPage 14 foranaidinselecting
ventlength combinations. Elbowsare available
in 45° and 90° configurations. Refer to Figure
24 on Page 16 for the SV4.5E45 and SV4.5E90
elbow dimensional specifications.
Where required, a Telescopic Vent Section
(SV4.5LA) 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 SV4.5LA Telescopic Vent Section
has an effective length of from 1-1/2" (38 mm)
to 7-1/2" (191 mm). The SV4.5LA is fitted with
a locking inclined channel end (identical to a
normalventsectioncomponent)andaplainend
with 3 pilot holes. Slip the plain end over the
locking channel end of a standard SV4.5 vent
component the required distance and secure
with three screws.
Maintain a minimum 1" (25 mm) clearance
to combustible materials for all vertical ele-
ments.Clearancesforallhorizontalelements
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, 10-1/2" x 10-1/2" (267 mm x 267
mm)inside dimensions, about this center mark
(Figure 18).

- Secure Flex) at the bottom side of the ceiling
to the ceiling 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) clear-
ance between vertical chimney sections and
combustibles, framing members, and attic
or ceiling insulation.
D2. Install firestop thimble at the ceiling to
roof location - Position appropriate firestop

ceilings or Figure 20 for pitched roofs with
cathedral ceilings.
To attach a vent component to the appliance
collar, align the dimpled end over the collar,
adjustingtheradialalignmentuntilthefourlock-
ing dimples are aligned with the inlet of the four
inclined channels on the collar (refer to Figure
19).Pushtheventcomponentagainstthecollar

Vent components will engage and seal both the
innerandouterpipe withouttheneedforsealant
or screws. If desired a #6 x 1/2" screw may be
used at the joint, but it not required as the pipe
will securely lock when twisted.
Note: An elbow may also be attached to the
appliance collar. Attach in the same manner
as you would a vent section.
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
installedsection, adjusting the radial alignment
until the four locking dimples are aligned with
the inlets of the four incline channels of the
previous section.
B. Attach vent components to appliance - Se-
cure Vent SV4.5 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 com-
ponents fit over the appliance collar to create
the positive twist lock connection.

Another method, where the vent is not adjacent
to a wall, is illustrated in Figure 23. Here,
support straps (96K93) and support plates
(96K92) can be used to support the weight
of the vent.
E. Support the vertical vent run sections -
Note- Properventingsupportis 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-
vided support straps (conventional plumber's
tape). Secure the plumber's tape to the framing
members with nails or screws. Loop the tape
aroundthevent, securingtheendsofthetapeto
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 22.

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 sup-
port on multiple joint configurations.
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 clear-
ancestocombustibles:1" (25mm)atallsides
forallvertical 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 and Figure 25.
K. Install the vertical termination - The final
Step involves installation of the SV4.5CGV-1
Vertical Termination. Extend the vent sections
to the height as shown in the "Vertical vent
termination section" (Page 6, Figures 3A and
3B). The SV4.5CGV-1 Vertical Termination
(Figure 27) can be installed in the exact same
fashionasany other Secure Ventsection.Align
the termination over the end of the previously
installedsection,adjustingtheradialalignment
untilthe four locking dimples of thetermination
are aligned with the inlets of the four incline
channels of the last vent section. Push the ter-
mination down until it fully engages, then twist
the termination clockwise running the dimples
down and along the incline channels until they
are seated at the end of the channels.
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 - see Figure 26) . 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, suppliedwith the flashing, over the vent/
flashingjoint. SeeFigure 26. Loosenthestorm
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.

Analyze the vent routing and determine the
types and quantities of sections required
4-1/2"(114mm),10-1/2" (267mm),22-1/2" (572
mm), 34-1/2" (876 mm) and 46-1/2" (1181 mm)
net section lengths are available. It is recom-
mended that you plan the vent lengths so that
a section joint does not occur within the space
definedbyceilingjoists,roofraftersorwallstuds.
MakeallowancesforelbowsasindicatedinFigure
24 on Page 16.
Maintain a minimum 1" (25 mm) clearance to
combustibles on the vertical sections. Clear-
ances for the horizontal runs are; 3" (76 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 exte-
rior wall according to the dimensions shown in
Figures 11 and 12 on Pages 10 and 11.
Cut and/or frame an opening, 10-1/2" x 12-1/8"
(267 mm x 308 mm) inside dimensions, about
this center.

to Figure 18 on Page 15).
D. Attach vent components to appliance - To
attachaventcomponentto 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
19 on Page 15).
Push the vent component against the collar
until it fully engages, then twist the component
clockwise,runningthedimplesdownandalong
the incline channels until they seat at the end of
thechannels. Theunitizeddesign oftheSecure
Ventcomponentswill engageand sealboththe
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
previouslyinstalledsectioninaccordancewith
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 19 on
Page 15.
F. Install firestop / spacer at ceiling -
Install a Secure Vent SV4.5VF firestop/spacer
at the bottom side of the ceiling to the ceiling
joists. Route the vent sections through the
framedopeningandsecure the firestop/spacer
with appropriate fasteners at each corner.
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
tocombustibles, framingmembers, andattic
or ceiling insulation when running vertical
chimney sections. Attic insulation shield
(H3907) may be used to obtain the required
clearances indicated here. See installation
accessories tables on Pages 34 through 36.
G. Support the vertical run sections -
See Step E on Page 16.
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 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 24 on Page 16.
I.Continueinstallationofhorizontal/ inclined
sections - Continue with the installation of the
straightventsectionsinhorizontal/inclinedrun
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 33. 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 fireplace of 1/4" rise per foot (20 mm
per meter) which is ideal, though rise per foot
runratiosthataresmallerare 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.
