Table 2
Typical Locations
The location should also be free of electrical,
plumbing or other heating/air conditioning duct-
ing. 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 locat-
ing television sets and decorative plants.
To provide for the lowest possible shelf surface
use the alternate rear vent outlet with attached
venting routed in a way to minimize obstructions
to the use of the space above the appliance. Do
not insulate the space between the appliance
and the area above it. See
Figure 3
. 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
.
The appliance should be mounted on a fully
supported base extending the full width and
depth of the unit. The appliance may be located
on or near conventional construction materi-
als. However, if installed on combustible ma-
terials, such as carpeting, vinyl tile, etc., a
metal or wood barrier covering the entire bot-
tom surface must be used.
APPLIANCE AND VENT CLEARANCES
These appliances are approved with zero clear-
ance from spacers to combustible materials on
all sides (as detailed in
Table 2
), with the
following exception: When the unit is installed
with one side flush with a perpendictular side
wall, the wall perpendicular to the opposite side
of the appliance front face must not extend
more than five inches beyond the front edge of
the unit. In addition, when the unit is recessed,
the side walls surrounding the unit must not
extend more than five inches beyond the front
edge of the unit. Refer to
Figure 2
.

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 5) Construct the appliance fram-
ing. Position the appliance within the framing
and secure with nailing brackets.
Step 2. (page 5) Route gas supply line to
appliance location.
DETAILED INSTALLATION STEPS
The appliance is shipped with all gas controls
and components installed and pre-wired. Re-
move the shipping carton, exposing the front
glass door. Remove the top panel. Remove the
cardboard from underneath the pressure re-
lief plates. Gently depress the outer top cor-
ners of the access panel until the catches "pop"
the panel free, allowing it to swing out and down
to open. Open the two latches (located under
the firebox floor) securing the glass door. Re-
move the door by tilting it outward at the
bottom and lifting it up. Set the door aside
protecting it from inadvertent damage.
See
Figure 55 on page 23.
Step 1. FRAMING
Frame these appliances as illustrated in
Figure 9 on page 7,
unless the appliance is
to be installed in a corner
.
The fireplace should be secured to the side
framing members using the unit's nailing flanges
- one top and bottom on each side of the
fireplace front. See
Figure 6.
Use 8d nails or
their equivalent.
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 appli-
ance top spacers but must not be supported by
them or notched to fit around them. All construc-
tion above the appliance must be self supporting.
DO NOT use the appliance for structural support.

Select Venting System - Horizontal or Vertical
With the appliance secured in framing, deter-
mine vent routing and identify the exterior
termination location. The following sections
describe vertical (roof) and horizontal (exte-
rior wall) vent applications. Refer to the sec-
tion relating to your installation. A list of
approved venting components is shown in
the two tables on page 24 and the two tables
on page 25.
Installation of Vent Restrictor
A vent restrictor may be needed with this appli-
ance, install the vent restrictor (provided) in the
appliance top flue outlet as shown in
Figure 15
or rear flue outlet as shown in
Figure 16
. It is
held in place by friction, only.
Step 3. INSTALL THE VENT SYSTEM
General Information
These instructions should be used as a guide-
line and do not supersede local codes in any
way. Install vent according to local codes,
these instructions, the current National Fuel
Gas Code (ANSI-Z223.1) in the USA or the
current standards of CAN/CGA-B149.1 and -
B149.2 in Canada.
These fireplaces are designed, tested and
listed for operation and installation with,
and only with, Secure Vent™ (SV 4.5) Direct
Vent System Components, Secure Flex™
Flexible Vent Components manufactured by
Security Chimneys International. These
approved vent system components are la-
beled for identification.
DO NOT use any
other manufacturer's vent components with
these appliances. These fireplaces must be
vented directly to the outside.
The vent system may not service multiple appli-
ances, 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.
Preparing the Appliance Vent Collar on
D-500/600/800 Series (Combined Top
and Rear Vent) Models
Each of the unit's two vent collars are sealed
with a cover plate and a seal plate and gasket.
The cover, and seal plate and gasket must be
removed from the vent collar being used.
Refer to
Figure 13
for top vent usage and
Figure 14
for rear, and the following steps to
prepare the appropriate collar for use.
From the vent collar being used, remove the
four screws securing the vent seal plate and
gasket. Remove and discard the seal plate and
gasket.
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, remove the two screws
securing the lintel to the rear wall of the fire-
box, then remove the lintel. Remove the four
cover plate securing screws.

Figure 17
VERTICAL TERMINATION SYSTEMS (ROOF)
Figure 17, and Figures 27 through 31 on
pages 13 and 14
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
local codes for specific requirements. A gen-
eral guide to follow is the Gas Vent Rule (refer
to
Figure 4
on page 5).
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.

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 20.
D. Install firestop/spacer at ceiling - When using
Secure Vent, use SV4.5BF firestop/spacer at ceil-
ing joists; when using Secure Flex, use SF4.5BF
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 appro-
priate fasteners at each corner.
Remember to maintain 1" (25 mm) clear-
ance 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 sys-
tem every 8 feet (2.4m) above the fireplace vent
outlet using field provided support straps (con-
ventional plumber's tape).
Secure the plumber's
tape to the framing members with nails or
screws.

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 13 and 14 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 10 for an aid in
selecting length combinations. Elbows are avail-
able in 90° and 45° configurations. Refer to
Figure 22
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.
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,
10¹⁄₂" x 10¹⁄₂" (267mm x 267mm) inside dimen-
sions, about this center mark (
Figure 18
).
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 19
). 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 com-
ponents 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.
Note: An elbow may also be attached to the
appliance collar. Attach in the same manner as
you would a vent section.
C. Attach vent components to each other -
Other vent sections may be added to the pre-
viously installed section in accordance with
the requirements of the vertical vent figures
and tables.
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 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 termina-
tion section" on page 5. The SV4.5CGV-1 Verti-
cal Termination (
Figure 26
) installs in the exact
same fashion as any other Secure Vent section.
Align the termination over the end of the previ-
ously installed section, adjusting the radial align-
ment until the four locking dimples of the termi-
nation 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
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 24
). Nail along perim-
eter 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 nec-
essary. 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.
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.
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 23
.
J. Install the storm collar - Install the storm
collar, supplied with the flashing, over the
vent/flashing joint. See
Figure 25.
Loosen the
storm collar screw. Slide collar down until it
meets the top of the flashing. Tighten the
adjusting screw. Apply non-combustible caulk-
ing or mastic around the circumference of the
joint to provide a water tight seal.
Figure 22
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 . Refer to
Figure 21.
F. Change vent direction to horizontal/in-
clined run - At transition from or to a horizon-
tal/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 22
.

ratios that are smaller are acceptable all the
way down to at or near level.
Note: SV4.5BF (Secure Vent), SF4.5BF (Se-
cure Flex) firestop/spacer must be used any-
time 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 com-
bustible 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 32
Secure Vent SV4.5 direct vent system compo-
nents are unitized concentric pipe components
featuring positive twist lock connection, (
refer to
Figure 19
on page 11). 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 allow-
ances for elbows as indicated in
Figure 19
.
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 9
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 18
on page 11 ).
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 19
on page 11 ).
G. Support the vertical run sections -
See Section E on page 11.
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.
Note: An elbow may also be attached to the
appliance collar. Attach in the same manner as
you would a vent section.
E. Attach vent components to each other -
Other vent sections may be added to the previ-
ously 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 20 on page 11.
F. Install firestop/spacer at ceiling -
When using Secure Vent, use SV4.5BF firestop/
spacer at ceiling joists; when using Secure Flex, use
SF4.5BF 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 32.
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.
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
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 9¹⁄₄ in. (235 mm)
inboard of the exterior surface to which the
termination is to be attached, see
Figure 34
.
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.
Figure 32, and Figures 36 to 43 on pages 17,
18 and 19
and their associated Horizontal Vent
Table illustrate the various horizontal venting
configurations that are possible for use with
these appliances. Secure Vent pipe applica-
tions are shown in these figures; Secure Flex
pipe may also be used. A Horizontal Vent Table
summarizes each system’s minimum and maxi-
mum vertical and horizontal length values that
can be used to design and install the vent
components in a variety of applications.
HORIZONTAL (OUTSIDE WALL)
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 re-
quired direction of the next vent run ele-
ment. Twist elbow sections in a clockwise
direction only so as to avoid the possiblity
of unlocking any of the previously con-
nected vent sections. See
Figure 22
.
Remember to maintain 1" (25 mm) clear-
ance to combustibles, framing members,
and attic or ceiling insulation when running
vertical chimney sections.
Push the vent component against the collar
until it fully engages, then twist the compo-
nent clockwise, running the dimples down
and along the incline channels until they seat
at the end of the channels.

M. Install the desired termination -
See the horizontal venting figures for appli-
cation restrictions on the round termination
(SV4.5HTR) and the small square horizontal
termination (SV4.5HTSS).
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
34
, refer to
table 3 on page 17
. 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 tele-
scoping vent section), elbow or appliance col-
lar as shown in
Figure 33
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
34
, and nail into place. (The Firestop/Spacer
may also be installed over the opening at the
interior side of the framing.) When using the
round termination, a separate firestop/spacer
is not required since this termination has inte-
gral spacers which provide the same function
as a separate firestop/spacer.
2. Install the round termination (SV4.5HTR)
–See
Figure 35
for an illustration of the round
termination. 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.
1. Install the square termination (SV4.5HTS)
or (SV4.5HTSS)- For the last step , from outside
the exterior wall, slide the collars of the termina-
tion onto the adapter (the outer over the outer
and the inner inside the inner) until the termina-
tion 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. The
horizontal termination must not be recessed
into the exterior wall or siding by more than the
1 ¹⁄₄" (32 mm) as shown in
Figure 34
.
Installing the Square Horizontal Termination (SV4.5HTS), Small Square
Horizontal Termination (SV4.5HTSS) or Round Horizontal Termination
(SV4.5HTR).
The SV4.5HTR Round Termination may not
be used when the appliance is vented di-
rectly out the wall from the rear (as shown in
Figures 36 or 37
on page 17). Do Not recess
the SV4.5HTR round termination at all.
SFHRK Snorkel Cap –The snorkel cap is de-
signed to be fitted into a basement window
box. The SFHRK cap is for use with flex vent
pipe. The vertical distance between the inlet
and outlet of the cap is 28 in. (711 mm).

VERTICAL OR HORIZONTAL VENTING USING
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 circum-
stances 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 con-
siderations 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 appli-
ance collar, adjusting the radial alignment until
the four locking dimples of the adapter are
aligned with the inlets of the four incline chan-
nels 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.
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
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 45
. Support
horizontal sections of flex with metal straps at
2 foot (0.61 m) intervals.
Attach the flexible vent to the adapter as
follows (see also
Figure 44
):
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, approxi-
mately 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.
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
compo-
nents. The collars of
Secure Flex
termina-
tions and adapters have a different circum-
ference 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.
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 44)
as it was at-
tached to the adapter.

Step 4. FIELD WIRING
Refer to Section A for millivolt appliances and
Section B for electronic appliances. The gas
valve is set in place and pre-wired at the
factory on both models.
1. Route a 3-wire 120Vac 60Hz 1ph power
supply to the appliance junction box.
2. If the factory-provided outlet/junction box
at the right rear of the fireplace is being used,
remove the outlet box from the junction box by
removing two screws.
3. Connect the power supply wires (includ-
ing the ground supply wire) as shown in
Figures 48or 49.
(If the field-provided J-box/
outlet box is being used, all of the outlet box
wiring must be field-provided.)
4. Locate and install a low voltage (24V) wall-
mounted switch or thermostat (both field-
provided) in the desired location.
5. Connect the low voltage wire (located in-
side the bottom compartment of the unit) to
the wall-mounted switch or thermostat.
Note: The supplied 15 feet of 2 conductor wire has one
end of each conductor connected to the gas valve
circuit and the other end of each conductor placed
loose inside the bottom compartment of the unit.
6. Insert the control circuit plug into the
unswitched receptacle of the outlet box.
7. After wiring is complete, mount the outlet
box to the J-Box.
A. SIT and Honeywell Millivolt Wiring
(See Figure 46)
–
1. Select any of the following optional con-
trols: appliance-mounted (rocker switch) or
wall-mounted switch, thermostat, or one of
the optional remote control kits. If appliance-
mounted ON/OFF control is selected mount it
in the gas valve mounting bracket.
2. If wall-mounted ON/OFF control or ther-
mostat is selected mount it in a convenient
location on a wall near the fireplace.
3. Wire the control switch within the millivolt
control circuit using the 15 feet of 2 conductor wire
supplied with the unit . Caution: do not connect the
optional wall switch to a 120V power supply.
4. Alternatively, the appliance may be operated
without the use of the controls indicated in step 1,
solely by manipulating the gas valve control knob. In
order to use this method, twist the free ends of the two
conductor wire (located inside the bottom compart-
ment of the unit) together as shown in
Figure 46
.
Note: The supplied 15 feet of 2 conductor wire has one
end of each conductor connected to the gas valve
circuit and the other end of each conductor placed
loose inside the bottom compartment of the unit.
Note: The gas valve-mounted ON/OFF switch is shown
in Figure 48 or 49. It is integral with the gas valve
and should be set to the ON position.
Step 5. WIRING - OPTIONAL FORCED AIR
BLOWER KIT
FBK-100, FBK-200 and FBK250 Kits
(See Figure 48 for FBK-100, FBK-200 and
Figure 49 for FBK-250 wiring)
-
An electrical outlet box (receptacle) is factory -
provided for the installation of the FBK-100, FBK-
200 and FBK-250 forced air blower kits. (An
optional field-provided outletbox/J-Box may also
be used. Electrical power must be connected to
either of these receptacles in order to operate these
blowers. Install the blower kits according to the
installation instructions provided with the kits.
Note: The tab connecting the receptacles of the
outlet box must be broken in FBK-100 and FBK-
200 blower kit applications.
B. Electronic Wiring
(See figure 48 or 49)
–
A junction box is located at the rear of the control
compartment on either side of the cabinet. The
junction box on the right side contains a factory
installed and wired outlet box (duplex recep-
tacle). Also, an optional field-provided junction
box with receptacle may be installed at the front
of the control compartment on either side of the
cabinet.
See Figure 47.
It will be held in place
by a conduit fitting and locknut (field-provided).
IMPORTANT: Ground supply wire must be
connected to the green wire attached to the
outlet receptacle's green ground screw. See
Figure 48 or 49
. Failure to do so will result in
a potential safety hazard. The appliance
must be electrically grounded in accordance
with local codes or, in the absence of local
codes, the National Electrical Code, ANSI/
NFPA 70-(latest edition). (In Canada, the
current CSA C22-1 Canadian Electrical Code.)

Make gas line connections. All codes require a
shut-off valve mounted in the supply line.
Fig-
ure 50
illustrates two methods for connecting
the gas supply. The flex-line method is accept-
able in the U.S., however, Canadian require-
ments 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

Step 8. CHECKING APPLIANCE OPERATION
With gas line installed run initial system checkout
before closing up the front of the unit. Follow the
pilot lighting instructions provided in the
Homeowner's Care and Operation Instructions.
For piezo ignitor location see
Figure 52
(SIT and
Honeywell millivolt appliances only).
Note: Instructions are also found on the litera-
ture tag attached to the gas valve train.
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 re-
quire such purging. Inspect the pilot flame (remove
logs, if necessary, handling carefully).
Step 7. INSTALLING LOGS, DECORATIVE
VOLCANIC STONE AND GLOWING EMBERS
Turn on gas supply and test for gas leaks using
a soapy water solution. Never use an open
flame to check for leaks.
Electronic Appliance Checkout
To light the burner, turn ‘ON’ the optional
remote wall switch and turn the gas control
switch to the “ON” position. Ensure the ignitor
lights the pilot. The pilot flame should engulf
the flame rod as shown in
Figure 55
.
OPENING CONTROL
COMPARTMENT DOOR
The packaged logs are located within the fire-
box. The decorative volcanic stone and glowing
embers are packaged separately in plastic bags
located in the control area of the fireplace.
Refer to the Homeowner's Care and Operation
Guide for detailed placement instructions for
decorative volcanic stone, and to the Log Place-
ment Guide for detailed placement instructions
for logs and glowing embers (rockwool).
SIT and Honeywell Millivolt Appliance Checkout
The pilot flame should be steady, 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 53
- SIT, Figure 54 - Honeywell
)
Replace logs if removed for pilot inspection.
To light the burner; turn “ON” the remote wall
switch and rotate the gas valve control knob
counterclockwise to the “ON” position.

Step 11. HOOD INSTALLATION
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 sur-
faces 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, move the adjustment rod
(located in the lower control area) up or down
to increase or reduce the air shutter opening,
respectively. Initially, always position the air
shutter to the factory setting (the minimum air
opening position) as shown in
Figure 57
. This
can be done by pulling the adjustment rod all
the way down. Allow the burner to operate for
at least 15 minutes. Observe the flame continu-
ously. 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 adjustment rod and associated adjustable air
shutter is patented technology. Flame adjust-
ments can be made quickly and accurately to taste
without the need of disassembling the appliance
and waiting for 30 minutes after each adjustment.
Note: If the flame still appears anemic with the
air shutter closed all the way against the stop
(usually a result of lengthy vertical runs), turn
the appliance off, turn the gas supply off, wait
for the parts to cool, remove the glass door and
logs to access the air shutter. The shutter is
prevented from actually closing all the way by
an adjustment set screw (see Figure 57 ). Re-
move this screw using a
¹⁄₄
inch nut driver.
Reinstall the logs and glass door, turn the gas
back on and then restart the appliance. After 30
minutes, reobserve the flame. Adjust the air
shutter as previously described.
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.
Burner Adjustment
Step 9. INSTALLING THE GLASS DOOR
Retrieve the glass door. Visually inspect the
gasket on the backside of the frame. Gasket
surface must be clean, free of irregularities
and seated firmly.
Position the door in front of the firebox opening
with the bottom of the door held away from the
fireplace
(Figure 56
). Hook the top flange of the
door frame over the top of the firebox frame.
Let the bottom of the door frame swing gently
in towards the fireplace ensuring that the gas-
ket seats evenly as the door frame draws shut.
Fasten the two latches located underneath the
firebox floor to the door's vee-flange. Close
both the latches securely.
WARNING: AIR SHUTTER ADJUSTMENT
SHOULD ONLY BE PERFORMED BY A
QUALIFIED PROFESSIONAL SERVICE
TECHNICIAN.
IMPORTANT: ENSURE THAT THE FRONT
GLASS PANEL IS IN PLACE AND SEALED
DURING ADJUSTMENT.
CAUTION: THE ADJUSTMENT ROD AND
NEARBY APPLIANCE SURFACES ARE HOT.
EXERCISE CAUTION TO AVOID INJURY
WHILE ADJUSTING FLAME APPEARANCE.
WARNING: NEVER OPERATE THE APPLI-
ANCE WITHOUT THE FRONT GLASS EN-
CLOSURE PANEL IN PLACE AND SECURE.
WARNING: HANDLE THIS GLASS WITH EX-
TREME CARE! THE GLASS PANEL IS SUS-
CEPTIBLE TO DAMAGE — DO NOT SCRATCH
WHILE HANDLING OR WHILE RE-INSTALL-
ING THE GLASS DOOR FRAME.

COLD CLIMATE INSULATION
If you live in a cold climate, 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.
Non-combustible materials, such as surrounds
and other appliance trim, may be installed on
the appliance front face with these exceptions:
they must not cover any portion of the glass or
louvers; they may cover any portion of the top
radiant panel or the air gaps surrounding the
top radiant panel up to the installed hood.
Vertical installation clearances to combustible
mantels vary according to the depth of the
mantel. See
Figure 61
. Mantels constructed
of non-combustible materials may be installed
at any height above the appliance opening;
however, do not allow anything to hang below
the hood.
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.
Note: Combustible wall finish materials and/or
surround materials must not be allowed to
encroach the area defined by the appliance
front face (black sheet metal). Never allow
combustible materials to be positioned in
front of or overlapping the appliance front
face. See Figure 58 and Figure 59.
