COLD CLIMATE INSULATION
TOP VENT INSTALLATIONS
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 open-
ings should be caulked or stuffed with unfaced
fiberglass insulation.

INSTALLATION
If the fireplace is being installed on a cement
slab in cold climates, a sheet of plywood or
otherraisedplatformcanbeplacedunderneath
to prevent cold transfer to the fireplace and into
the room. It also helps to sheetrock inside
surfaces and tape for maximum air tightness
and caulk firestops.

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 appli-
ance and the area above it (see Figure 8). 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 8.

Notes:
Step 2. ROUTING GAS LINE
to Table 6 for proper sizing of the gas sup-
ply 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 qualified 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 supply line from the fuel supply to the
appliance involves numerous considerations of
materials,protection,sizing,locations,controls,
pressure, sediment, and more. Certainly no one
unfamiliarandunqualifiedshouldattemptsizing
or installing gas piping.
• All appliances are factory-equipped with
a flexible gas line connector and 1/2 inch
shutoff valve (see Figure 39 on Page 24).
• SeeMassachusettsRequirementsonPage
4 foradditionalrequirementsforinstallations
in the state of Massachusetts in the USA.
• ThegassupplylineshouldNotbeconnected
to the appliance until Step 6 (Page 24).
• Apipejointcompoundratedforgasshouldbe
usedonthethreadedjoints.Ensurepropane
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(seeFigure39). Appliancesusing
Propane should have a sediment trap at the
base of the tank.
Route a 1/2" (13 mm) gas line along the inside
of the left side framing as shown in Figure 15.
Gaslinesmustberouted,constructedandmade
of materials that are in strict accordance with

nector and 1/2 inch shutoff valve. (See Step 6

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
orothermalfunctions). Anydamageresulting

nents are unitized concentric pipe components
featuring positive twist lock connections (see
Figure 18).
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 17 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 an
aidinselectinglengthcombinations.Elbowsare
available in 90° and 45° configurations. Refer
to Figure 20 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 compo-
nents fit over the appliance collar to create the
positive twist lock connection.
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. 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
whenrunningverticalchimneysections.Attic
insulation shield may be used to obtain the
required clearances indicated here (order
H3907, SV4.5ARSA, Attic insulation shield
with adjustable height from 12"-22"). See
installation accessories table on Page 32.
The gap between the vent pipe and a vertical
firestop can be sealed with non-combustible
caulking.

(25 mm) on the bottom.
E. Support the vertical vent run sections -
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 18). 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.
Note-Properventingsupportisveryimportant.
The weight of the vent must not be supported
by the fireplace in any degree.
Support the vertical portion of the venting
system every 8 feet (2.4m) above the fireplace
vent outlet.
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" (267 mm x 267
mm)insidedimensions, aboutthiscentermark
(Figure 17).
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 it is not required as the
pipe will securely lock when twisted.

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 6. The SV4.5CGV-1
Vertical Termination (Figure 23) 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 four locking dimples
of the termination are aligned with the inlets of

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.

ing or mastic around the circumference of the
joint to provide a water tight seal.
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 sup-
port on multiple joint configurations.

sections (see Figure 18 on Page 15).
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"(876mm)and46-1/2"(1181mm)
net section lengths are available. It is recom-
mended that you plan the vent lengths so that a
jointdoesnotoccurattheintersectionofceiling
or roof joists. Make allowances for elbows as
indicated in Figure 20 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 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.
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
straightventsectionsinhorizontal/inclinedrun
as described in Step E. Install support straps
every 5 ft. (1.52 m) along horizontal/inclined
vent runs using conventional plumber’s tape.
B. Frame exterior wall opening -
Locate the center of the vent outlet on
the exterior wall according to the dimen-
sions shown in Figure 12 on Page 10. Cut
and/or frame an opening, 10-1/2" x 12-1/8"
(267 mm x 308 mm) inside dimensions, about
this center.
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 18 on
Page 15.
See Figure 27, 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.

Horizontal terminations have been designed to perform in a wide range of weather condi-
tions. Our terminations meet or exceed industry standards.
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.
Take care to carefully follow the installation instructions for the termination, including
the use of silicone caulking where required.

logs if removed for pilot inspection.
Step 7. VERIFYING APPLIANCE OPERA-
TION
Turn on burner then 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.
To light the burner; rotate the gas valve control
knob counterclockwise to the “ON” posi-
tion and turn “ON” the appliance mounted
ON/OFF switch (or optional remote switch, if
installed).
WARNING
Never use an open flame to
check for leaks.
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 solu-
tion 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.
With gas line installed run initial system check-

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 lighting
of the appliance will not require such purging.

WARNING
• DO NOT attempt to install the logs until the
appliance installation has been completed, the
gas line connected and tested for leaks and the
initial burner operation has been checked out.
• The size and position of the log set was engi-
neered to give the appliance a safe, reliable
and attractive flame pattern. Any attempt to use
a different log set in the fireplace will void the
warranty and will result in incomplete combus-
tion, sooting, and poor flame quality.

• Logs get very hot and will remain hot up to one
hour after gas supply is turned off. Handle only
when logs are cool. Turn off all electricity to the
appliance before you install logs and embers.
• This appliance is not designed to burn wood.
Any attempt to do so could cause irreparable
damage to the appliance and prove hazardous
to your safety.
• If logs are not installed according to the log

The adjustment rod and associated adjustable
air shutter is patented technology. Flame ad-
justments can be made quickly and accurately
to taste without the need of disassembling the
appliance and waiting for 30 minutes after each
adjustment.
Step 10. BURNER ADJUSTMENTS
Flame Appearance and sooting
Burner Air Shutter Adjustment Procedure
WARNINGS
Proper flame appearance is a flame which is
blueatthebaseandbecomesyellowish-orange
in the body of the flame. When the appliance
is first lit, the entire flame may be blue and will
graduallyturnyellowish-orangeduringthefirst
15 minutes of operation. After 15 minutes of
operation, if the flame is blue, or if the flame is
orange with evidence of sooting (black tip), the
air shutter opening may need to be adjusted.
• Air shutter adjustment should
only be performed by a quali-
fiedprofessionalservicetech-
nician.
• Ensure front glass panel are
in place and sealed during
adjustment.
When satisfied that the appliance operates
properly, proceed to finish the installation.
Leave the control knob in the ON position and
the burner ON/OFF switch (or optional remote
switch) in the OFF position. Close the lower
control compartment panel.
If the air shutter opening is closed too far,
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.
Note: See Figure 53 for proper burner flame
appearance.
CAUTIONS
• Soot will be produced if the
airshutterisclosedtoomuch.
Any damage due to carboning
resulting from improperly
setting the air shutter is not
covered under the warranty.
• Theairshutterdoorandnearby
appliance surfaces are hot.
Exercise caution to avoid
injury while adjusting flame
appearance.
Front of Burner
Sootingiscausedbyincompletecombustionin
the flames and lack of combustion air entering
the air shutter opening. To achieve a warm yel-
lowish-orange flame with an orange body that
does not soot, the shutter opening must be
adjusted between these two extremes.

Rod
Reach around the
left side of the
valve to locate

Air Shutter Adjustment Guidelines
• 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.
To adjust the flame, move the lever arm up or
down(locatedinthelowercontrolareaasshown
in Figure 52). When the arm is positioned all
the way down it is fully open. When the arm is
positioned all the way up, it is closed.
• Themoreoffsetsintheventsystem,thelarger
the air shutter opening will need to be.
Ensure that the air shutter is closed (push lever
all the way up).
• An appliance operated with the air shutter
opened too far, may have flames that appear
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.
CAUTION: DO NOT BEND THE AIR SHUTTER
ROD. MAKE SURE THE AIR SHUTTER MOVES
WHEN THE LEVER ARM IS OPERATED.
Valve
Observe the flame continuously. If it appears
weak or sooty as previously described, adjust
the air shutter up or down until the flame ap-
pearance is as desired.
Adjustment
All the way up = CLOSED
All the way down = OPEN
Adjust the rod to the full closed position for
both Natural Gas and Propane. Light the fire-
place, then adjust accordingly after heat-up.
The following chart is provided to aid you in
achieving the correct air shutter adjustment
for your installation.
