LOCATION
In selecting the location, the aesthetic and func-
tionaluseoftheapplianceareprimaryconcerns.
However, vent system routing to the outside
atmosphere and access to the fuel supply are
alsoimportant.Considerationshouldbegivento
traffic ways, furniture, draperies, etc., due to
high surface temperatures (Figure 2 ). The loca-
tionshouldalsobefreeofelectrical,plumbingor
other heating/air conditioning ducting.
*Eachmodelhastwoburners.Eachburnercontains
one of these orifices.
These appliances and their individual shut-off
valves must be disconnected from the gas
supply piping system during any pressure test-
ing of that system at pressures in excess of ¹⁄₂
psig (3.5 kPa).

Carbon Monoxide Poisoning: Early signs of
carbon monoxide poisoning are similar to
the flu with headaches, dizziness and/or
nausea. If you have these signs, obtain fresh
air immediately. Turn off the gas supply to
the appliance and have it serviced by a
qualified professional, as it may not be op-
erating correctly.
To achieve the lowest possible shelf height, use
the alternative rear vent outlet. Do not insulate
the space between the appliance and the area
aboveit. SeeFigure3onpage4.Theminimum

vent height above the roof and/or adjacent
walls is specified in ANSI Z223.1(latest edi-
tion); 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).

The dimpled end of the vent components fit over
the appliance collar to create the positive twist
lock connection.
Vertical (Offset) Installation
This seating position is indicated by the align-
ment of the arrow and dimple as shown in
Figure 24.
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), 22¹⁄₂" (572 mm), 34¹⁄₂" (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 dimen-
sional specifications.
Where required, a telescopic vent section
(SV4.5LA) may be used to provide the installer
with an option in installing in tight and con-
fined spaces or where the vent run made up of
fixed length pieces develops a joint in a unde-
sirable location, or will not build up to the
required length. The SV4.5LA Telescopic Vent
Section has an effective length of from 1¹⁄₂" (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 se-
cure with three screws.
D. Install firestop/spacer at ceiling - When
usingSecureVent,useSV4.5VFfirestop/spacer
at ceiling joists; when using Secure Flex, use
SF4.5VF firestop/spacer. If there is living space
abovetheceilinglevel,thefirestop/spacermust
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.Routetheventsectionsthroughtheframed
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 mem-
bers, and attic or ceiling insulation when
running vertical chimney sections. Attic insu-
lation shield (96K94) may be used to obtain
the required clearances indicated here. See
installation accessories table on page 26.

Support the vertical portion of the venting sys-
temevery8feet(2.4m)abovethefireplacevent
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.

Clearances for all horizontal elements are 3"
(76 mm) on top, 1" (25 mm) on sides and 1"
(25 mm) on the bottom.
To attach a vent component to the appliance
collar, align the dimpled end over the collar,
adjusting the radial alignment until the four lock-
ing 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
theinclinechannelsuntiltheyseatattheendofthe
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.
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 cen-
ter mark (Figure 22).
Another method, where the vent is not adjacent
toawall,isillustratedinFigure26.Here,support

Secure Vent SV4.5 direct vent system compo-
nents are unitized concentric pipe compo-
nents 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.
Push the vent component against the collar
until it fully engages, then twist the compo-
nentclockwise, runningthedimplesdownand
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.
Remember to maintain 1" (25 mm) clearance
to combustibles, framing members, and at-
tic or ceiling insulation when running verti-
cal 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.
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 27 on
page 13.
E. Attach vent components to each other -
Other vent sections may be added to the previ-
ously installed section in accordance with the
requirementsoftheventtables. Toaddanother
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
seatingpositionisindicatedbythealignment
ofthearrowanddimpleasshowninFigure24
on page 12.
H. Change vent direction - At transition from
ortoahorizontal/inclinedrun,installtheSV4.5E45
and SV4.5E90 elbows in the same manner as the
straightventsections. Theelbowsfeatureatwist
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.
Maintain a minimum 1" (25 mm) clearance to
combustiblesontheverticalsections.Clearances
for the horizontal runs are; 3" (76 mm) on top, 1"
(25 mm) on sides, and 1" (25 mm) at the bottom.
I. Continueinstallationofhorizontal/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/
inclinedventrunsusingconventionalplumber’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.
B. Frame exterior wall opening -
Locate the center of the vent outlet on the exterior
wallaccordingtothedimensionsshowninFigures
9(CDST),10(CDPF),11(CDCL),or12(CDCR)on
page7. Cutand/orframeanopening, 10¹⁄₂"x12¹⁄₈"
(267 mm x 308mm) inside dimensions, about this
center.
F. Install firestop/spacer at ceiling -
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 ).
When using Secure Vent, use SV4.5VF fir-
estop/spacer at ceiling joists; when using Se-
cure Flex, use SF4.5VF firestop/spacer. If there
is living space above the ceiling level, the fir-
estop/ 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/spacerwith8dnailsorotherappropriate
fasteners at each corner.
D. Attach vent components to appliance - To
attach a vent component to the appliance collar,
alignthedimpledendoverthecollar,adjustingthe
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).
It is important to maintain the required clear-
ancestocombustibles:1"(25mm)atallsides
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 Fig-
ure 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

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.
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 - approxi-
mately every 6 inches - and avoid kinking of
inner pipe. Support horizontal sections of flex
with metal straps at 2 foot (0.61m) intervals.
Note: Secure Flex vent must be attached to
Secure Flex terminations only. DO NOT sub-
stitute Secure Vent terminations or the Se-
cure Vent adapter for Secure Flex compo-
nents. The collars of Secure Flex termina-
tions 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.

the flexible vent pipe and into the adapter collar
just below the gear clamp to provide additional
security to the connection.
D. Install Firestop/Spacers at ceilings and walls -
When Secure Flex penetrates a wall or ceil-
ing, a firestop/spacer is required: use the
SF4.5 VF firestop/spacer for ceilings and the
SF4.5 HF firestop/spacer for walls.
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.

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 purg-
ing. Inspect the pilot flame (remove logs, if
necessary, handling carefully).

Step 6. CONNECTING GAS LINE
Figure 54
Millivolt Appliance Checkout
Make gas line connections. All codes require a
shut-off valve mounted in the supply line. Fig-
ure 53 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.
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.
Secure all joints tightly using appropriate
tools and sealing compounds (ensure pro-
pane resistant compounds are used in pro-
pane applications).
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 en-
gulfed in the pilot flame. The flame should
project 1" (25 mm) beyond the hood at all three
ports (Figure 55).
Turn on gas supply and test for gas leaks using
a soapy water solution. Never use an open
flame to check for leaks.
These appliances are equipped with a gas flex
lineforuse(wherepermitted)inconnectingthe
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.
A. Mix a 50% dish soap, 50% water solution.
Replace logs after pilot inspection.
B. Light the appliance (refer to the lighting
instructionsprovidedintheHomeowner'sCare
and Operation Instructions).
Tolighttheburner:turn“ON”theunit-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.
C. Brush all joints and connections with the
soapywatersolutiontocheckforleaks.Ifbubbles
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.
The gas control valve is located in the lower
control compartment. To access the valve pro-
ceed as follows: Open the control compart-
ment 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.

To light the burner, turn ‘ON’ the the wall-
mounted ON/OFF switch or the thermostat
(depending on the type of control installed),
and turn the gas control switch to the “ON”

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 sur-
facesadjacenttotheventtermination.Sootingis
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.

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.
Orifice
Nosmokeorsootshouldbepresent. 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.
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.
