operation. External electrical power (110 vac)
is recommended to operate these units. If the
system operates on line voltage with 6V fan
control module, four (4) "AA" batteries can be
used as a backup in case of a power outage. The
electronic appliance can be operated without a
fan, solely with four (4) "AA" batteries.

These vented gas fireplace heaters are sealed
combustion, air-circulating gas fireplaces de­signed for residential applications.

Approved Vent Components - These fireplaces
are designed, tested and listed for operation
and installation with, the following vent com­ponents only:

NEW YORK CITY, NEW YORK (MEA)

Installation of these fireplaces are approved
for installation in New York City in the US state
of New York.

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.

Note: 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.

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.

MANUFACTURED HOME

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: 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 accord­ing 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.

DETAILED INSTALLATION STEPS

Right Side

Front Corner of

Fireplace Framing

6"

(152 mm)

3"

(76 mm)

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 follow­ing steps for detailed procedures.

See Figure 12 on page 10 for the facing detail.
See Figure 13 on page 10 for the Non-Com­bustible requirements. See Figures 14 and 15

on page 11 for Hearth Requirements.

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

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" inch shutoff
valve. (See step 5 on page 23).

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

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 opera­tion.
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.

Figure 17

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 Z­FLEX™ Model GA Venting Systems listed
to UL1777 and ULCS635 manufactured by
Flexmaster Canada Limited.

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 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 verti­cal 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 speci­fied in ANSI Z223.1-(latest edition) (In Canada,
the current CAN-1 B149 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 6).

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 ).

Figure 19

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 com­ponents fit over the appliance collar to create
the positive twist lock connection.

Figure 20

Figure 21

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" 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.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

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" length may be
used to secure the support straps to the vent
pipe . See Figure 22.

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.

See Figure 23.

Figure 23

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' (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" 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.

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 carpen­ters 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.

Figure 26

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.

16

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 and Figure 24.

Figure 25

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 ad­justing screw. Apply non-combustible caulking
or mastic around the circumference of the joint
to provide a water tight seal.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Figure 27

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.

WARNING

Under no circumstances may
separate sections of concentric
flexible vent pipe be joined
together.

Note: 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.

Note: SV4.5VF (Secure Vent), SF4.5VF (Secure
Flex) firestop/spacer must be used anytime vent
pipe passes through a combustible floor or ceil­ing. 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.

*When developing chimney systems
with horizontal runs (H) that end with
a vertical run (V1), it is allowable to
use an elbow attached directly to the
top collar. Count the elbow attached
to the collar as 1 foot of (V) run.

TYPICAL HORIZONTAL VENT INSTALLATION

HORIZONTAL (OUTSIDE WALL)
TERMINATION SYSTEM

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 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 6 on page 7 for location guidelines.

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, 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

20 on page 15).

18

Figure 31

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 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 on page 15.

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 ARE NOT TO SCALE.

Remember to maintain 1" (25 mm) clearance
to combustibles, framing members, and attic
or ceiling insulation when running vertical
chimney sections.

G. Support the vertical run sections ­See Section E on page 15.

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.

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.

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 termina­tion 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.

SFHRK Snorkel Cap –The snorkel cap is
designed to be fitted into a basement window
box. The SFHRK cap is for use with flex vent
pipe. The SV4.5HRK14 and SV4.5HRK36 are
for rigid vent pipe.

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.

Figure 32

Figure 33

Installing the Square Horizontal Termination (SV4.5HT-2).

Horizontal terminations have been designed to perform in a wide range of weather condi­tions. 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.

SECURE FLEX KITS AND COMPONENTS

Secure Flex venting kits and components may
be used in any venting application where rigid
Secure Vent (SV4.5) direct vent components
can be used. 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. 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 included adapter
that can be fitted to the appliance collar or 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 37 ):

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
inches 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 inch 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.

22

Figure 37

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.

2. Apply a bead of Mill-Pac Black (700°F) high
temperature sealant - Catalog No. 10K81) to

the outer adapter collar; to the grooves of the
collar which extend approximately 1 inch from
the end and to the flat surface, approximately
1-3/8 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 1-3/4
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 38. Support
horizontal sections of flex with metal straps at
2 foot (0.61 m) intervals.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Figure 38

D. 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. When using this method connect the
flex vent only to Flex Vent terminations, not
Secure Vent terminations. Secure the flexible
vent to the Secure Flex terminations in the same
manner (see Figure 37 ) 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 circumference 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.

The junction box assembly is located inside the
control compartment close to the front right
side corner (see Figure 39 ). This junction
box contains a standard electrical junction box,
pre-wired duplex receptacle, a cover plate and a
conduit fitting (clamp connector). If desired, the
whole junction box assembly may be moved to
the left hand side of the control compartment.
A knock-out is provided on the cabinet wrapper
for positioning.

1. Route a 3-wire 120Vac 60Hz 1ph power
supply to the appliance.

2. Remove the metal cover plate and the duplex
receptacle from the junction box assembly (un­plug fan control power cord from receptacle).

3. From the outside of the fireplace, loosen
clamp screws on the conduit fitting. Run power
supply wires (including the ground supply wire)
through conduit fitting. Tighten mounting nut
of conduit fitting.

4. Connect the power supply wires to the duplex
receptacle as shown in Figure 40.

5. Reassemble duplex receptacle and cover
plate on junction box. Tighten conduit fitting
clamp screws to secure supply wires.

Figure 39

See Figure 41 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 (refer to Figure 48
on page 27 ). The RF control millivolt valve has
a 1/2" (13 mm) NPT thread inlet port.

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 gas leak test solution (also referred to as
bubble leak solution).

Note: Using a soapy water solution (50%
dish soap, 50% water) is an effective leak test
solution but it is not recommended, because
the soap residue that is left on the pipes/fittings
can result in corrosion over time. Never use

an open flame to check for leaks.

A. Light the appliance (refer to the lighting

instructions label in the control compartment
or in the Homeowner's Care and Operation
Instructions).

B. Brush all joints and connections with the gas
leak test 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.

6. Insert the fan control power cord into the
duplex receptacle.

WARNING

This appliance is equipped with
a three-prong (grounding) plug
for your protection against shock
hazard and should be plugged
directly into a properly grounded
three-pronged receptacle. Do
not cut or remove the grounding
prong from this plug.

Step 5. CONNECTING GAS LINE

Make gas line connections. All codes require a
shut-off valve mounted in the supply line. Figure
41 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.

Figure 40

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.

Figure 41-

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

GAS CONNECTION

C. When the gas lines are tested and leak free,

be sure to rinse off the leak testing solution.

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.

Flame Appearance and sooting

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 develop.

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 logs if flames impinge on any of them. If the
logs are 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.

To adjust the flame, rotate the air shutter
adjustment rod toward the back or toward
the front of the fireplace (rod located in the
lower control area). Position the air shutter
to the factory setting as shown in the Table
of Figure 49. Allow the burner to operate for
at least 15 minutes. Observe the flame continu­ously. If it appears weak or sooty as previously
described, adjust the air shutter by pushing or
pulling on the adjustment rod until the flame
appearance is as desired.

The air shutter 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 30
minutes after each adjustment.

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.

Vent Restrictor

The appliance has a built-in vent restrictor,
refer to Figure 49 for location of the adjustment
rod, to adjust the flow of exhaust gases. This
ensures proper combustion for all vent configu­rations. Depending on the vent configuration,
you may be required to adjust the restriction
position. See below for guidelines.

CAUTION

The fireplace needs to be on
during the adjustment of the vent
restrictor. Use a glove to protect
your hand from burns.

Venting

Configuration

1. Horizontal Venting
with 6" vent section and
one 90° elbow.

2. Vertical venting.

3. Combination of ver­tical and horizontal

burner orifices (refer to Figure 54 ) from their
respective manifolds and replace them with the
ones provided in this kit. There are two main
burner orifices provided in this gas conversion
kit. Refer to Table below for the correct front
and rear main burner orifice sizes for the gas
being used. The orifice size is stamped on the
orifice. See Figure 55.

WARNING

Incorrect orifice size installation
on either burner may result in
poor combustion which may
lead to the production of carbon
monoxide. It may also cause
sooting within the fireplace/
venting system.

Step 15. Reassemble all removed 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). Adjust the air
shutter opening on the burner tube, referring
to Figure 49 on page 27.
