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 conduction of cold transferring to
the fireplace and into the room. It also helps to
sheetrock inside surfaces and tape for maximum
air tightness and caulk firestops.

MINIMUM CLEARANCES TO COMBUSTIBLES
Appliance And Vent Clearances
The appliance is approved with zero clearance to combustible materials on
all sides (as detailed in Table 6 ), with the following exception: When the
unit is installed with one side flush with a wall, the wall on the other
side of the unit must not extend beyond the front edge of the unit. In
addition, when the unit is recessed, the side walls surrounding the unit
must not extend beyond the front edge of the unit (see Figure 2).
*Note: 3 in. (76 mm) above any horizontal/inclined vent component.
**Note: See Page 9, Step 1 for clearance requirements to the nailing
flange located at each side of the unit and any screw heads adjacent
to it.
Hearth Extension - A hearth extension is not required with this appliance.
If a hearth extension is used, do not block the lower control compartment
door. Any hearth extension used is for appearance only and does not have
to conform to standard hearth extension installation requirements.
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
appliance 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 en-croach 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 50 on Page 34).
Non-combustible materials, such as surrounds and other appliance trim,
may be installed on the appliance face with these exceptions: they must
not cover any portion of the removable glass panel.
Vertical installation clearances to combustible mantels vary accord-
ing to the depth of the mantel. See Figure 8. 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
fireplace hood.
Combustible materials may
project beyond one side
of the fireplace opening
as long as they are kept
within the shaded areas
illustrated here.

DETAILED INSTALLATION STEPS
The appliance is shipped with all gas controls and
components installed and pre-wired. Remove
the shipping carton, exposing the front glass
door. Remove ceramic panel kit from the top of
the fireplace and set it aside with care. Remove
the cardboard from underneath the pressure
relief plates. Open the two latches (located
under the firebox floor) securing the glass
door. Remove the door by tilting it outward at
the bottom and lifting it up. Set the door aside
protecting it from inadvertent damage. See
Figure 48 on page 27.
TYPICAL INSTALLATION SEQUENCE
The typical sequence of installation follows,
however, each installation is unique resulting
in variations to those described.
See the page numbers references in the follow-
ing steps for detailed procedures.
Step 1. (page 13) Construct the appliance fram-
ing. Position the appliance within the framing
and secure with nailing brackets.
Step 2. (page 13) Route gas supply line to
appliance location.
Step 3. (page 13) Install the vent system and
exterior termination.
Step 4. (page 23) Field Wiring
Install the operating control switch (not factory
provided) and bring in electrical service line for
forced air circulating blower.
Step 5. (page 23) Make connection to gas
supply.
Step 6. (page 26) Install the ceramic panel,
logs, and glowing embers.
Step 7. (page 26) Checkout appliance opera-
tion.
Step 8. (page 26) Install glass door frame
assembly.
Step 9. (page 27) Adjust burner to ensure
proper flame appearance.
Step 10. (page 28) Affix warning labels.
Step 1. FRAMING
Frame these appliances as illustrated in
Figure 10 on page 9, unless the appliance is to
be installed in a corner. See Figure 11 on page
9 for corner framing installations. All framing
details must allow for a minimum clearance to
combustible framing members as shown in
Table 6 on page 8.
See Figure 12 on page 10 for the facing detail.
See Figure 13 on page 10 for the Non-Com-
bustible requirements. See Figures 14 and 15
on page 11 for Hearth Requirements.

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 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.
These fireplaces are designed, tested
and listed for operation and installation
with, and only with, Secure Vent
Direct Vent System Components,
Secure Flex Flexible Vent
Components manufactured by Security
Chimneys International and Z-FLEX
Model GA Venting Systems listed to
UL1777 and ULCS635 manufactured by
Flexmaster Canada Limited.
NOTE: The flow of combustion and
ventilation air must not be obstructed.
These approved vent system components
are labeled for identification. DO NOT
use any other manufacturer's vent
components with these appliances.
Some local jurisdictions may require the gap
between the outer wall of the vent system and
the firestop penetration opening to be sealed.
This is not a requirement of the listing of this
product, however this gap may be sealed using
aluminized tape or similar non-combustible
material.
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 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.
Select Venting System - Horizontal or Vertical
With the appliance secured in framing, de-
termine vent routing and identify the exterior
termination location. The following sections
describe vertical (roof) and horizontal (exterior
wall) vent applications. Refer to the section
relating to your installation. A list of approved
venting components is shown in the two tables
on page 29.
VERTICAL TERMINATION SYSTEMS (ROOF)
Figure 18, and Figures 28 through 30
on pages 14 and 17 and their associated
Vertical Vent Tables illustrate the various verti-
cal venting configurations that are possible for
use with these appliances. Secure Vent pipe
applications are shown in these figures; Secure
Flex pipe may also be used. A Vertical 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 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-1 B149 installation code) by
major building codes. Always consult your lo-
cal codes for specific requirements. A general
guide to follow is the Gas Vent Rule (refer to
Figure 4 on page 6).
Step 2. ROUTING GAS LINE
Route a 1/2 in. (13 mm) gas line along the inside
of the right side framing as shown in Figure 17.
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 in. (13 mm)
shutoff valve. (See step 5 on page 23).
14 NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
Figure 18
Vertical (Offset) Installation
Analyze the vent routing and determine the
quantities of vent sections and number of el-
bows required. Refer to Vertical Vent Figures
and Tables on page 17 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 this page for an
aid in selecting length combinations. Elbows are
available in 90° and 45° configurations. Refer
to Figure 23 for the SV4.5E45 and SV4.5E90
elbow dimensional specifications.
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
available. 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 on this page.

B. Attach vent components to appliance
- Secure Vent SV4.5 direct vent system compo-
nents are unitized concentric pipe components
featuring positive twist lock connections (see
Figure 20 ).
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.

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 20 ). 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 in. (13 mm) screw
may be used at the joint, but 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 21.
D. Install firestop/spacer at ceiling - When
using Secure Vent, use SV4.5VF firestop/spacer
at ceiling joists; when using Secure Flex, use
SF4.5VF firestop/spacer. 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.
E. Support the vertical vent run sections
-Support the vertical portion of the venting
system every 8 feet (2.4m) above the fireplace
vent outlet using field provided support straps
(conventional plumber's tape). Secure the
plumber's tape to the framing members with
nails or screws.
Loop the tape around the vent, securing the
ends of the tape to the framing. If desired, sheet
metal screws #6 x 1/2 in. (13 mm) length may
be used to secure the support straps to the vent
pipe . See Figure 22.
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
normal vent section component) and a plain end
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 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, 10-1/2" x 10-1/2" (267mm x 267mm)
inside dimensions, about this center mark
(Figure 19 ).

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" in Figure 4 on page 6. The
SV4.5CGV-1 Vertical Termination (Figure 27 )
installs 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 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.
I. Install the roof flashing - Extend the vent sec-
tions through the roof structure. Install the roof
flashing over the vent section and position such
that the vent column rises vertically (use carpen-
ters level) (Figure 25 ). 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.
If the vent system extends more than 5' (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.
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 5 ft (1.52 m) along horizontal/inclined
vent runs using conventional plumber’s tape. 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 in. 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. 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-
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.
H. Frame roof opening - Identify location for
vent at the roof. Cut and/or frame opening per
Roof Framing Chart and Figure 24.
J. Install the storm collar - Install the storm
collar, supplied with the flashing, over the
vent/flashing joint. See Figure 26. Loosen the
storm collar screw. Slide collar down until it
meets the top of the flashing. Tighten the ad-
justing screw. Apply non-combustible caulking
or mastic around the circumference of the joint
to provide a water tight seal.

F. Change vent direction to horizontal/inclined
run - At transition from or to a horizontal/in-
clined 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 possiblity of unlocking
any of the previously connected vent sections.

elevated plane, in a direction away from the
fireplace of 1/4 in. 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.
Note: SV4.5VF (Secure Vent), SF4.5VF (Secure
Flex) firestop/spacer must be used anytime vent
pipe passes through a combustible floor or ceil-
ing. SV4.5HF (Secure Vent), SF4.5HF (Secure
Flex)firestop/spacer must be used anytime vent
pipe passes through a combustible wall.
Note: Two 45 degree elbows may be used in
place of one 90 degree elbow. The same rise
to run ratios, as shown in the venting figures
for 90 elbows, must be followed if 45 degree
elbows are used.

TYPICAL HORIZONTAL VENT INSTALLATION
Figure 31
Secure Vent SV4.5 direct vent system components
are unitized concentric pipe components featuring
positive twist lock connection, (refer to Figure 21
on page 15). 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.
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 joint does not occur at
the intersection of ceiling or roof joists. Make
allowances for elbows as indicated in Figure
23 on page 16. Maintain a minimum 1" (25
mm) clearance to combustibles on the vertical
sections. Clearances 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 exterior
wall according to the dimensions shown in Figure
10 on page 9. Cut and/or frame an opening,
10-1/2" x 12-1/8" (267 mm x 267 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 15 ).
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 15).
G. Support the vertical run sections -
See Section E on page 15.
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 compo-
nents will engage and seal both the 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 pre-
viously installed section in accordance with 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 lock-
ing 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 15.
F. Install firestop/spacer at ceiling -
When using Secure Vent, use SV4.5VF restop/
spacer at ceiling joists; when using Secure
Flex, use SF4.5VF firestop/spacer. 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.
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 31. 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
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.
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 7 for location guidelines.
Figure 31, and Figures 34 to 36 on pages 20
and 21 and their associated Horizontal Vent
Table illustrate the various horizontal venting
configurations that are possible for use with
these appliances. Secure Vent pipe applications
are shown in these figures; Secure Flex pipe
may also be used. A Horizontal Vent Table sum-
marizes 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.

TERMINATION SYSTEM
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 possiblity
of unlocking any of the previously connected
vent sections. See Figure 23.
Remember to maintain 1" (25 mm) clearance
to combustibles, framing members, and attic
or ceiling insulation when running vertical
chimney sections.

IMPORTANT: The vent termination is
hot while in operation and for a period
of time following use of the fireplace.
To prevent contact with hot surfaces,
we recommend the use of a Termination
Guard. This can be purchased at your
local dealer.
Horizontal terminations have been designed to perform in a wide range of weather condi-
tions. Our terminations meet or exceed industry standards.
When selecting the locations of your horizontal terminations, do not place the termination
where water from eaves and adjoining rooflines may create a heavy flow of cascading water
onto the termination cap. If the cap must be placed where the possibility of cascading water
exists, it is the responsibility of the builder to direct the water away from the termination
cap by using gutters or other means.
Take care to carefully follow the installation instructions for the termination, including the
use of silicone caulking where required.

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
J. Assemble vent run to exterior wall - If not
previously measured, locate the center of the
vent at the exterior wall. Prepare an opening as
described in Step B. Assemble the vent system
to point where the terminus of the last section
is within 5 in. (127 mm) to 9-1/4 in. (235 mm)
inboard of the exterior surface to which the
termination is to be attached, see Figure 33.
If the terminus of the last section is not within
this distance, use the telescopic vent section
SV4.5LA, as the last vent section. For wall
thicknesses greater than that shown in Figure
33, refer to Table 7 on page 20. This table lists
the additional venting components needed (in
addition to the termination and adapter) for a
particular range of wall thicknesses.
K. Attach termination adapter - Attach the
adapter (adapter - SV4.5RCH - provided with the
termination) to the vent section or telescoping
vent section), elbow or appliance collar as shown
in Figure 32 in the same manner as any SV4.5
vent component (refer to Step E).
L. Install Firestop/Spacer at exterior wall
- When using the square termination, install
SV4.5HF (Secure Vent), SF4.5HF (Secure Flex)
Firestop/Spacer over the opening at the exterior
side of the framing, long side up, with the 3 inch
spacer clearance at the top as shown in Figure
32, and nail into place. (The Firestop/Spacer
may also be installed over the opening at the
interior side of the framing).
1. Install the square termination (SV4.5HT-2)
- For the last step , from outside the exterior
wall, slide the collars of the termination onto
the adapter (the outer over the outer and the
inner inside the inner) until the termination seats
against the exterior wall surface to which it will
be attached. Orient the housing of the termina-
tion with the arrow pointed upwards. Secure
the termination to the exterior wall.
Orient the housing of the termination with the
arrow pointed upwards. Secure the termination
to the exterior wall.
