LOCATION
In selecting the location, the aesthetic and functional use of the appliance are primary concerns.
However, vent system routing to the outside
atmosphere and access to the fuel supply are
also important. Consideration should be given to
traffic ways, furniture, draperies, etc., due to
high surface temperatures (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 shelves
like these are commonly used for locating television sets and decorative plants.
To achieve the lowest possible shelf height, use
the alternative rear vent outlet. Do not insulate
the space between the appliance and the area
above it. See Figure 3 on page 4. 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 the
table in Figure 3 on page 4. The weight of the
utility shelf and anything placed upon it may not
be supported by the appliance in anyway.

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 following steps for detailed procedures.
Step 1. (page 5) Construct the appliance
framing. Position the appliance within the
framing and secure with nailing brackets.
Step 2. (page 10) Route gas supply line to
appliance location.
Step 3. (page 10) Install the vent system and
exterior termination.
Step 4. (page 22) Field Wiring
A. Millivolt Appliances – The operating control
switch is factory installed.
B. Electronic Appliances – Connect 120 Vac
electrical power to the appliance receptacle.
Step 5. (page 22) Install blower kit (optional
equipment).
Step 6. (page 23) Make connection to gas
supply.
Step 7. (page 23) Install the log set, decorative volcanic stone and glowing embers.
Step 8. (page 23) Checkout appliance operation.
Step 9. (page 24) Install glass enclosure
panels.
Step 10. (page 24) Adjust burner primary air
shutter to achieve proper flame appearance.
Step 11. (page 25) Install the hoods.

3 - Lift the pressure relief plates and remove
the cardboard from underneath each of them.
4 - Open the control compartment access panel
by actuating the spring loaded magnetic catches
securing the panel, gently depressing the outer
top corners of the panel until the catches "pop"
the panel free, allowing it to swing out and
down to open.
5 - Open the two latches (located under the
firebox floor) securing the glass enclosure
panel. Remove the panel by tilting it outward at
the bottom and lifting it up. Set the door aside
protecting it from inadvertent damage. See
Figure 57 on page 24.

All framing details must allow for a minimum clearance to combustible framing
members as shown in Table 2 on page 4 .

Note: The CDST fireplace is installed in the
framing by cocking it at an angle, fitting the
collar side in first and then twisting and pushing
the other side in. To minimize the obstruction,
it is helpful to make sure the cap is removed
from the rear collar.
If the appliance is to be elevated above floor level,
a solid continuous platform must be constructed.
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.

Top Louver Panel

Side Nailing Flanges

Step 1. FRAMING

The fireplace should be secured to the framing
at the side(s) and/or rear of the unit using the
factory-provided nailing flanges. Install the
nailing flanges - 8 (CDST), 4 (CDPF, CDCL and
CDCR) - as shown in Figure 7 using the
existing screws. Position the fireplace within
the framing. When required, the flanges 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 2 on page 4 for clearances of framing
members to cabinet parts in the nailing flange
area. The nailing flange itself is exempt from
these clearances.

Frame these appliances as illustrated in
Figures 9 (CDST), 10 (CDPF), 11 (CDCL)
or 12 (CDCR).

Step 2. ROUTING GAS LINE
Route a ¹⁄₂" (13 mm) gas line as shown in Figure
9 (CDST), 10 (CDPF), 11 (CDCL) or 12 (CDCR)
on pages 8 and 9. 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 23).

Step 3. INSTALL THE VENT SYSTEM

When the top vent collar is being used, from
inside the firebox, loosen the two screws in the
keyhole slots of the cover plate and remove the
remaining two cover plate securing screws.
Remove and discard the cover plate. Reinstall
and securely tighten all four screws.
When the rear vent collar is being used, from
inside the firebox, loosen the two screws in the
keyhole slots of the cover plate and remove the
remaining two cover plate securing screws.
Remove and discard the cover plate. Reinstall
and securely tighten all four screws.

Preparing the Appliance Top or Rear Vent
Outlet when vertically terminating the vent
system above the roof
A vent restrictor may be needed with this
appliance, install a vent restrictor (provided)
in the appliance top flue outlet as shown in
Figure 19 or side flue outlet as shown in
Figure 20 when vertically terminating the vent
system above the roof. It may be installed
either from inside or outside the unit, in the
inner fireplace collar. It is press-fitted in place.

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. These approved vent system components are labeled for identification. DO NOT use

These fireplaces must be vented directly
to the outside.
The vent system must 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 enclosure (such as a chase). There is no requirement for inspection openings in the enclosure
at any of the joints in the vent pipe.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

With the appliance secured in framing, determine 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 27.

VERTICAL TERMINATION SYSTEMS (ROOF)

Figure 21, and Figures 32 through 36 on
pages 14 and 15 and their associated Vertical
Vent Tables illustrate the vertical venting configurations that 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 21. 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. In the USA, the minimum
vent height above the roof and/or adjacent
walls is specified in ANSI Z223.1(latest edition); in Canada, by the current CAN-1 B149
installation code. It is also specified in 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 4).
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 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
page 14 and 15 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 11 for an aid in selecting
length combinations. Elbows are available in
45° and 90° configurations. Refer to Figure 27
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 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.

The dimpled end of the vent components fit over
the appliance collar to create the positive twist
lock connection.

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, 10¹⁄₂" x 10¹⁄₂" (267mm x
267mm) inside dimensions, about this center mark (Figure 22) .

Figure 22
B. Attach vent components to appliance - Secure Vent SV4.5 direct vent system components
are unitized concentric pipe components featuring positive twist lock connections (see Figure
23 ). All of the appliances covered in this document are fitted with collars having locking inclined channels.
12

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
23). 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 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 24.
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. Attic insulation shield (96K94) may be used to obtain
the required clearances indicated here. See
installation accessories table on page 26.
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 firplace in any degree.
Support the vertical portion of the venting system every 8 feet (2.4m) above the fireplace vent
outlet. One method of support is by utilizing
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" length may be
used to secure the support straps to the vent
pipe. See Figure 25.
Another method, where the vent is not adjacent
to a wall, is illustrated in Figure 26. Here, support
straps (96K93) and support plates (96K92) can
be used to support the weight of the vent.

at the bottom for all horizontal/inclined runs.

J. Install the storm collar - Install the storm
collar, supplied with the flashing, over the vent/
flashing joint. See Figure 30. 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.

F. Change vent direction to horizontal/inclined run - 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 27.

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 29 ). 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.

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" on page 4. The SV4.5CGV-1 Vertical
Termination (Figure 31) 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 are
seated at the end of the channels.

Figure 27
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.
See page 16, Figure 37. 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.

Figure 31

Figure 29

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

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 support on
multiple joint configurations.

HORIZONTAL (OUTSIDE WALL)
TERMINATION SYSTEM

Figure 37, and Figures 40 to 46 on page 18 to
20 and their associated Horizontal Vent Table
illustrate the horizontal venting configurations
that 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 21. A Horizontal 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 of these horizontal vent systems terminate
through an outside wall. Building Codes limit or
prohibit terminating in specific areas. Refer to
Figure 8 on page 6 for location guidelines.
Secure Vent SV4.5 direct vent system components are unitized concentric pipe components featuring positive twist lock connection,
(refer to Figure 23 on page 12). 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. Make allowances for elbows as indicated in Figure 27 on
page 13.
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 Figures
9 (CDST), 10 (CDPF), 11 (CDCL), or 12 (CDCR) on
page 7. Cut and/or frame an opening, 10¹⁄₂" x 12¹⁄₈"
(267 mm x 308mm) 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, 10¹⁄₂" x 10¹⁄₂" (267
mm x 267 mm) inside dimensions, about this
center (refer to Figure 22 on page 12 ).
D. Attach vent components to appliance - 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 inlets of the four incline channels
on the collar (refer to Figure 23 on page 12).

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.
E. Attach vent components to each other Other vent sections may be added to the previously 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 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 24
on page 12.
F. 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.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Remember to maintain 1" (25 mm) clearance
to combustibles, framing members, and attic or ceiling insulation when running vertical chimney sections. Attic insulation shield
(96K94) may be used to obtain the required
clearances indicated here. See installation
accessories table on page 27.
G. Support the vertical run sections See section E on page 12.
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 27 on page 12.
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 37. 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.
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

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 7¹⁄₂ in. (191 mm) to 11³⁄₄ in. (298 mm)
inboard of the exterior surface to which the
SV4.5HT termination is to be attached, see Figure 39. 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 38, refer to Table 3 on page 18. 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 38 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 38, and nail into place.

VERTICAL OR HORIZONTAL VENTING USING
SECURE FLEX KITS AND COMPONENTS
Secure Flex venting kits and components may be
used in any venting application in place of rigid
Secure Vent (SV4.5) direct vent components. All
restrictions, clearances and allowances that pertain to the rigid piping apply to the flexible venting.
Secure Flex kits may not be modified; also,
under no circumstances may separate sections
of flex pipe be joined together.

FLEX VENT
NOTE: OUTER PIPE IS PULLED AWAY TO
SHOW THE DETAIL OF THE INNER PIPE
SECURING SCREW
(3 PLACES EQUIDISTANT
JUST BELOW GEAR CLAMP)
Apply ONLY MIL-PAC BLACK HIGH
TEMPERATURE SEALANT (Catalog No.
10K81) to the outside surface of both
collars of the adapter (be especially
careful to fill the grooves of the outer
collar to be covered by the flexible
pipe) and slide flexible pipe over
inner and outer adapter collars.

Using adapter (SV4.5RF), Secure Flex kits
may be added to the end of a vent run made up
of rigid Secure Vent (SV4.5) vent sections
provided that doing so does not violate any of
the venting length, height, routing, horizontal
to vertical ratio requirements or clearance
considerations detailed in this manual.
Secure Flex kits come with an adapter that can
be fitted to the inclined channel end of the last
Secure Vent (SV4.5) vent section in a rigid
system in the exact same fashion as any other
Secure Vent section.
Align the dimpled end of the adapter over the
previously installed section or appliance collar, adjusting the radial alignment until the four
locking dimples of the adapter are aligned with
the inlets of the four incline channels of the last
vent section or collar. Push on the adapter
until it fully engages, then twist the adapter
clockwise running the dimples down and along
the incline channels until they seat at the end
of the channels.
Attach the flexible vent to the adapter as
follows (also see Figure 47 ):
A. Install the Inner Flex Pipe 1. Install the small gear clamp loosely around
the inner flexible vent pipe, push it back out of
the way.
2. Apply a bead of Mill-Pac Black (700°F)
high temperature sealant - Catalog No.
10K81) to the inner adapter collar, approximately ¹⁄₂ inch from the end.
3. Pull and extend the inner flexible vent pipe.
4. Slide the inner flex pipe over the adapter
collar. Ensure the flexible vent pipe completely
engages the adapter collar to a distance of 1³⁄₄
inches from the end, and that it is free from
damage or tears.
5. Slide the gear clamp down and tighten it
fully to secure the flexible vent to the adapter
inner collar approximately ³⁄₄ inch from the
end of the flex.
6. Install three screws 120 degrees apart through
the flexible vent pipe and into the adapter collar
just below the gear clamp to provide additional
security to the connection.
B. Install the Outer Flex Pipe 1. Install the large gear clamp loosely around
the outer flexible vent pipe, push it back out of
the way.

the end and to the flat surface, approximately 1³⁄₈
inches from the end.
3. Pull and extend the outer flexible vent pipe.
4. Slide the outer flex pipe over the adapter
collar. Ensure the flexible vent pipe completely
engages the adapter collar to a distance of 1³⁄₄
inches from the end, and that it is free from
damage or tears.
5. Slide the gear clamp down and tighten it
fully to secure the flexible vent to the adapter
outer collar approximately ³⁄₄ inch from the
end of the flex.
6. Install three screws 120 degrees apart
through the flexible vent pipe and into the
adapter collar just below the gear clamp to
provide additional security to the connection.
C. Route Flex Vent Ensure that the flex vent is properly routed to
provide the required clearance. Do not allow
the flexible vent to bend in a radius tighter than
5" (127 mm). Refer to Figure 48. Space out the
internal flex vent spacers evenly - approximately every 6 inches - and avoid kinking of
inner pipe. Support horizontal sections of flex
with metal straps at 2 foot (0.61m) intervals.
D. Install Firestop/Spacers at ceilings and walls When Secure Flex penetrates a wall or ceiling, a firestop/spacer is required: use the
SF4.5 VF firestop/spacer for ceilings and the
SF4.5 HF firestop/spacer for walls.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

See the appropriate sections and figures
shown throughout the venting section for
their installation requirements.

E. Attach Flex Vent to Termination Secure Flex components can be purchased
separately and attached to bulk lengths of
Secure Flex flexible tubing cut to size at the
job site. Secure the flexible vent to the Secure
Flex terminations in the same manner (see
Figure 47 ) as it was attached to the adapter.
Note: Secure Flex vent must be attached to
Secure Flex terminations only. DO NOT substitute Secure Vent terminations or the Secure Vent adapter for Secure Flex components. The collars of Secure Flex terminations and adapters have a different diameter
than that used with the Secure Vent pipe.
Additionally, Secure Flex components have
an extended length center tube for use in
attaching the flexible vent.

Make gas line connections. All codes require a
shut-off valve mounted in the supply line. Figure 53 illustrates two methods for connecting
the gas supply. The flex-line method is acceptable in the U.S., however, Canadian requirements vary depending on locality. Installation
must be in compliance with local codes.
These appliances are equipped with a gas flex
line for use (where permitted) in connecting the
unit to the gas line. A gas flex line is provided
to aid in attaching the direct vent appliance to
the gas supply. The gas flex line can only be
used where local codes permit. See Figure 53
for flex line description. The flex line is rated for
both natural and propane gas. A manual shut
off valve is also provided with the flex line.
The gas control valve is located in the lower
control compartment. To access the valve proceed as follows: Open the control compartment access panel (Figure 54) by actuating the
spring-loaded magnetic catches securing the
panel, gently depressing the outer top corners
of the panel until the catches "pop" the panel
free, allowing it to swing out and down to open.
The millivolt control valve has a ³⁄₈"
(10 mm) NPT thread inlet port. The electronic
control valve has a ¹⁄₂" (13 mm) NPT thread inlet
port and is fitted with a ¹⁄₂" x ³⁄₈" (13 mm x
10 mm) NPT fitting.

The log set, a bag of decorative volcanic stone
and a bag of glowing embers (rockwool) is
supplied in the unit. Refer to the Homeowner's

Step 7. INSTALLING LOG SET, VERMICULITE AND CERAMIC FIBER CHUNKS

Secure all joints tightly using appropriate
tools and sealing compounds (ensure propane resistant compounds are used in propane applications).
Turn on gas supply and test for gas leaks using
a soapy water solution. Never use an open
flame to check for leaks.
A. Mix a 50% dish soap, 50% water solution.
B. Light the appliance (refer to the lighting
instructions provided in the Homeowner's Care
and Operation Instructions).
C. Brush all joints and connections with the
soapy water solution to check for leaks. If bubbles
are formed, or gas odor is detected, turn the gas
control knob to the “OFF” position. Either tighten
or refasten the leaking connection and retest as
described above.
D. When the gas lines are tested and leak
free, observe the individual tongues of flame
on the burner. Make sure all ports are open
and producing flame evenly across the
burner. If any ports are blocked, or partially
blocked, clean out the ports.

When first lighting the appliance, it will take
a few minutes for the line to purge itself of
air. Once purging is complete, the pilot and
burner will light and operate as indicated in
the instruction manual. Subsequent lightings
of the appliance will not require such purging. Inspect the pilot flame (remove logs, if
necessary, handling carefully).
Millivolt Appliance Checkout
The pilot flame should be steady and, not lifting
or floating. Flame should be blue in color with
traces of orange at the outer edge.
The top ³⁄₈" (10 mm) at the pilot generator
(thermopile) and the top ¹⁄₈" min (tip) of the
quick drop out thermocouple should be engulfed in the pilot flame. The flame should
project 1" (25 mm) beyond the hood at all three
ports (Figure 55).
Replace logs after pilot inspection.
To light the burner: turn “ON” the unit-mounted
ON/OFF switch or the wall-mounted ON/OFF
switch or the thermostat (depending on the
type of control installed), and rotate the gas
valve control knob counterclockwise to the
“ON” position.

clean, free of irregularities and seated firmly.
2. Position the glass enclosure panel in front
of the firebox opening at a 45 degree angle and
engage the top flange over the lip at the top of
the firebox opening. See Figure 57.
3. Swing the glass enclosure panel down and
back. Ensure the gasket seats evenly as the
panel draws shut. Engage the Vee-flange at
the bottom of the panel with the latches and
close the latches to secure the panel.

Proper flame appearance is a matter of taste.
Generally, most people prefer the warm glow of
a yellow to orange flame. Appliances operated
with air shutter openings that are too large will
exhibit flames that are blue and transparent.
These weak, blue and transparent flames are
termed anemic. If the air shutter opening is too
small sooting may occur.
Sooting is indicated by black puffs developing at
the tips of very long orange flames. Sooting
results in black deposits forming on the logs,
appliance inside surfaces and on exterior surfaces adjacent to the vent termination. Sooting is
caused by incomplete combustion in the flames
and lack of combustion air entering the air
shutter opening. To achieve a warm yellow to
orange flame with an orange body that does not
soot, the shutter opening must be adjusted
between these two extremes.
No smoke or soot should be present. Reposition
the log set if flames impinge on any part of it.
If the log set is properly positioned and sooting
conditions exist, the air shutter opening on the
main burner tube should be adjusted. Normally,
the more offsets in the vent system, the greater
the need for the air shutter to be opened further.

The adjustment rod and associated adjustable air
shutter is patented technology. Flame adjustments can be made quickly and accurately to taste
without the need of disassembling the appliance
and waiting for 15 minutes after each adjustment.
Propane models may exhibit a flame pattern
that may candle or appear stringy. If this is
problematic or persists as the appliance is
continually operated, adjust the air shutter
closed as described in the previous paragraphs.
Operate the appliance for a period of time as the
effect diminishes, ensuring that the appliance
does not develop sooty flames.
When satisfied that the appliance operates properly, proceed to finish the installation. Leave the
control knob in the ON position and the remote
switch OFF. Close the lower control compartment door.

B. Install rear burner first, followed by front
burner, as shown in Figure 69. Ensure that the
arm of the venturi of each burner is hooked
onto the air shutter adjustment lever (refer to
Figure 63 on page 27).The primary air opening can be adjusted by rotating the adjustment
lever from beneath the firebox floor. Refer to
Figure 58 on page 23 for the recommended
minimum primary air opening setting.

Step 9. Reassemble the remaining components by reversing the procedures outlined in
the preceding steps. Use pipe joint compound
or Teflon tape on all pipe fittings before installing (ensure propane resistant compounds are
used in propane applications, do not use pipe
joint compounds on flare fittings).
Step 10. Attach the conversion label provided
in the conversion kit to the rating plate on the
