• A pipe joint compound rated for gas should be
used on the threaded joints. Ensure propane
resistant compounds are used in propane
applications. Be very careful that the pipe
compound does not get inside the pipe.
• It is recommended to install a sediment trap
in the supply line as close as possible to the
appliance (see Figure 46). Appliances using
Propane should have a sediment trap at the
base of the tank.
Proper Sizing of Gas Line
Schedule 40 / Black Iron Pipe
Inside Diameter (Inches)
Properly size and route the gas supply line
from the supply regulator to the area where
the appliance is to be installed per require-
ments outlined in the National Fuel Gas Code,

Never use galvanized or plastic pipe. Refer to
Table 9 for proper sizing of the gas supply line,
if black iron pipe is being used. Gas lines must
be routed, constructed and made of materials
that are in strict accordance with local codes
and regulations. We recommend that a quali-
fied individual such as a plumber or gas fitter
be hired to correctly size and route the gas
supply line to the appliance. Installing a gas
supplylinefromthefuelsupplytotheappliance
involvesnumerousconsiderationsofmaterials,
protection,sizing,locations,controls,pressure,
sediment,andmore.Certainlynooneunfamiliar
andunqualifiedshouldattemptsizingorinstall-
ing gas piping.
• Check with local building official for local code
requirements(i.e.arebelowgradepenetrations
of the gas line allowed?, etc).
Table 9
IMPORTANT: If propane is used, be aware that
if tank size is too small (i.e. under 100-lbs, if
this is the only gas appliance in the dwelling.
Ref. NPFA 58), there may be loss of pressure,
resulting in insufficient fuel delivery (which
can result in sooting, severe delayed ignition
or other malfunctions). Any damage resulting
from an improper installation, such as this, is
not covered under the limited warranty.
Notes:
• All appliances are factory-equipped with a
flexiblegaslineconnectorand1/2inchshutoff
valve (see Figures 46 & 48).
• SeeMassachusettsRequirementsonPage4
for additional requirements for installations in
the state of Massachusetts in the USA.
• The gas supply line should Not be connected
to the appliance until Step 6 (Page 26).

General Information
WARNING
When There Is 3 Feet Or More Of Vertical
Venting, install a vent restrictor (provided) in
the appliance top or rear flue outlet as shown
in Figures 17a & 17b. It is held in place by
friction, only.
Failure to reinstall and securely
tighten cover plate screws could
result in leakage of flue products
into the living space. Vent cover
plate and vent seal plate must
remain securely installed on
unused vent collar. Failure to do
so could result in leakage of flue
products into living space.
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.

Both these vertical vent systems terminate
through the roof. The minimum vent height
above the roof and/or adjacent walls is speci-
fied in ANSI Z223.1-(latest edition) (In Canada,
the current CAN-1 B149 installation code) by
major building codes. Always consult your lo-
cal codes for specific requirements. A general
guide to follow is the Gas Vent Rule (refer to
Figure 4 on Page 7).

Vertical (Offset) Installation
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,
adjustingtheradialalignmentuntilthefourlock-
ing dimples are aligned with the inlets of the four
incline channels of the previous section.
B. Attach vent components to appliance
-SecureVentSV4.5directventsystemcompo-
nents are unitized concentric pipe components
featuring positive twist lock connections (see
Figure 20).
Analyze the vent routing and determine the
quantitiesofventsectionsandnumberofelbows
required. Refer to Vertical Vent Figures and
Tables on Pages 17 & 18 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 14 for
anaidinselectinglengthcombinations.Elbows
areavailablein90°and45°configurations.Refer
to Figure 22 on Page 16 for the SV4.5E45 and
SV4.5E90 elbow dimensional specifications.
All of the appliances covered in this document
are fitted with collars having locking inclined
channels. The dimpled end of the vent com-
ponents fit over the appliance collar to create
the positive twist lock connection.
Push the vent component against the previous
section until it fully engages, then twist the
componentclockwiserunningthedimplesdown
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.
Align the dimple (four places) of the
upper vent section with the opening
of the locking incline channel on the
lower vent section or appliance col-
lar. Twist vent component clockwise

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
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/spacermustbeinstalledonthetopside
of the joist. Route the vent sections through the
framed opening and secure the firestop/spacer
with 8d nails or other appropriate fasteners at
each corner. Remember to maintain 1" (25
mm) clearance to combustibles, framing
members, and attic or ceiling insulation
when running vertical chimney sections.
Attic insulation shield (96K94) may be used
to obtain the required clearances indicated
here. See installation accessories, Pages
32 through 34.
Where required, a telescopic vent section
(SV4.5LA) may be used to provide the installer
withanoptionininstallingintightand 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
normalventsectioncomponent)andaplainend

Clearances for all horizontal elements are 3"
(76 mm) on top, 1" (25 mm) on sides and 1"
(25 mm) on the bottom.
E. Support the vertical vent run sections -
Note-Properventingsupportisveryimportant.
The weight of the vent must not be supported
by the firplace in any degree.
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).
Support the vertical portion of the venting

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 ter-
mination section" on Page 7. The SV4.5CGV-1
VerticalTermination(Figure25)canbeinstalled
in the exact same fashion as any other Secure
Vent section. Align the termination over the
end of the previously installed section, adjust-
ing the radial alignment until the four locking
dimples of the termination are aligned with
the inlets of the four incline channels of the
last vent section. Push the termination down
until it fully engages, then twist the termination
clockwise running the dimples down and along
the incline channels until they are seated at the
end of the channels.
One method of support is by utilizing field pro-
vided support straps (conventional plumber's
tape). Securetheplumber'stapetotheframing
members with nails or screws. Loop the tape
around the vent, securing the ends of the tape
totheframing.Ifdesired,sheetmetalscrews#6

F. Changeventdirectiontohorizontal/inclined
run - At transition from or to a horizontal/in-
clined run, install the SV4.5E45 and SV4.5E90
elbows in the same manner as the straight vent
sections. The elbows feature a twist section to
allow them to be routed about the center axis
of their initial collar section to align with the
required direction of the next vent run element.
Twist elbow sections in a clockwise direction
only so as to avoid the possiblity of unlocking
anyofthepreviouslyconnectedventsections.

F. Install firestop/spacer at ceiling -
WhenusingSecureVent,useSV4.5VFfirestop/
spaceratceilingjoists;whenusingSecureFlex,
use SF4.5VF firestop/spacer. If there is living
spaceabovetheceilinglevel,thefirestop/spacer
must be installed on the bottom side of the
ceiling. If attic space is above the ceiling, the
firestop/spacermustbeinstalledonthetopside
ofthejoist. Routetheventsectionsthroughthe
framed opening and secure the firestop/spacer
with 8d nails or other appropriate fasteners at
each corner.
D. Attach vent components to appliance - To
attachaventcomponenttotheappliancecollar,
align the dimpled end over the collar, adjust-
ing the radial alignment until the four locking
dimples are aligned with the inlets of the four
incline channels on the collar (refer to Figure
20 on Page 15).
Bothofthesehorizontalventsystemsterminate
throughanoutsidewall. BuildingCodeslimitor
prohibit terminating in specific areas. Refer to
Figure 6 on Page 8 for location guidelines.
Secure Vent SV4.5 direct vent system compo-
nents are unitized concentric pipe components
featuring positive twist lock connection, (refer
to Figure 20 on Page 15). All of the appli-
ances 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 component
clockwise,runningthedimplesdownandalong
the incline channels until they seat at the end
of the channels.
Remember to maintain 1" (25 mm) clearance
to combustibles, framing members, and attic
or ceiling insulation when running vertical
chimney sections.
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.
G. Support the vertical run sections -
See Section E on Page 15.
A. Plan the vent run -
Analyze the vent routing and determine the
types and quantities of sections required
4-1/2"(114mm),10-1/2"(267mm),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 inter-
section of ceiling or roof joists. Make allowances
for elbows as indicated in Figure 22.
H.Changeventdirection -Attransitionfromor
toahorizontal/inclinedrun,installtheSV4.5E45
and SV4.5E90 elbows in the same manner as
thestraightventsections. Theelbowsfeaturea
twistsectiontoallowthemtoberoutedaboutthe
center axis of their initial collar section to align

element. Twist elbow sections in a clockwise
direction only so as to avoid the possiblity of
unlockinganyofthepreviouslyconnectedvent
sections. See Figure 22 on Page 16.
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 previously in-
stalledsectioninaccordancewiththerequirements
oftheventtables. Toaddanotherventcomponent
to a length of vent run, align the dimpled end of
the component over the inclined channel end of
the previously installed section,
Maintain a minimum 1" (25 mm) clearance to
combustibles on the vertical sections. Clear-
ances for the horizontal runs are; 3" (76 mm)
on top, 1" (25 mm) on sides, and 1" (25 mm)
at the bottom.

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.
To help minimize water infiltration it is
recommended that the Firestop/Spacer
(SV4.5HF) be installed on the exterior
side of the wall.

Horizontal terminations have been designed to perform in a wide range of weather condi-
tions. Our terminations meet or exceed industry standards.
IMPORTANT
When selecting the locations of your horizontal terminations, do not place the termina-
tion where water from eaves and adjoining rooflines may create a heavy flow of cascad-
ing 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.
The vent termination is hot while
in operation and for a period of
time following the use of the fire-
place. To prevent contact with hot
surfaces, we recommend the use
of a Termination Guard. See Items
12 and 13 on Page 32. This can be
purchased at your local dealer.
Take care to carefully follow the installation instructions for the termination, including
the use of silicone caulking where required.

M. Install the Square Termination (SV4.5HT-2)
See Table 12 as an aid in venting component selection for a particular
range of exterior wall thicknesses.
Install the square termination - For the last step , from outside the
exterior wall, slide the collars of the termination onto the adapter (the
outer inside the outer and the inner outside 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 33.

(thermopile) and the top 1/8" min (tip) of the
quickdropoutthermocoupleshouldbeengulfed
in the pilot flame. The flame should project 1"
(25 mm) beyond the hood at all three ports
(See Figure 49).
TEST ALL CONNECTIONS FOR GAS LEAKS
(FACTORY AND FIELD):
On millivolt systems, the piezo igniter, HI/LO
flame adjustment knob, and pilot and main
gas OFF/ON control knob are located below
the glass panel enclosure. The gas valve for
electronic systems is also located below the
glass enclosure panel. See Figure 48.
WARNING
Never use an open flame to
check for leaks.
To light the burner; rotate the gas valve control
knob counterclockwise to the “ON” position
then turn “ON” the OFF/ON switch (installed
at Step 4).
Reinstalling Control Compartment Door:
To reinstall, insert the hook catches on each
side of the door into the corresponding slots
in the control compartment opening, then
gently push forward and slide down until it
locks in place.
Turn on gas supply and test for gas leaks using a
gas leak test solution (also referred to as bubble
leaksolution). Note:Usingasoapywatersolution
(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.
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.
Step 7. CHECKING APPLIANCE OPERA-
TION
A. Light the appliance (refer to the lighting
instructions label in control compartment or
homeowner's manual).
With the gas line installed, run initial system
checkout before closing up the front of the
appliance. Followthepilotlightinginstructions
provided in the Homeowner's Care and Opera-
tion Instructions. For piezo igniter location see
Figure 48 (millivolt appliances only).
Replace logs if removed for pilot inspection.
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 (off/pilot/on) to the “OFF”
position. Either tighten or refasten the leaking
connection, then retest as described above.
C. Whenthegaslinesaretestedandleakfreebe

• If there is smoke or soot present, first check
the log set positioning to ensure that the
flames are not impinging on any of the logs.
If the log set is properly positioned and a
sooting condition still exists, then the air
shutter opening should be increased.
• Themoreoffsetsintheventsystem,thelarger
the air shutter opening will need to be.
• An appliance operated with the air shutter

blue and transparent. These weak, blue and
transparent flames are termed anemic.
• Propane models may exhibit flames which
candle or appear stringy. If this is present
and persists, adjust the air shutter to a more
closed position, then operate the appliance
for a few more minutes to ensure that the
flame normalizes and the flames do not
appear sooty.
