COLD CLIMATE INSULATION  
For cold climate installations, seal all cracks  
around your appliance with noncombustible  
material and wherever cold air could enter  
the room. It is especially important to insulate  
outside chase cavity between studs and under  
floor on which appliance rests, if floor is above  
ground level. Gas line holes and other open-  
ings should be caulked or stuffed with unfaced  
fiberglass insulation.  
Vertical  
Vent  
Horizontal Vent  
(top vent)  
If the fireplace is being installed on a cement  
slab in cold climates, a sheet of plywood or  
other raised platform can be placed underneath  
to prevent 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.

Appliance and Vent Clearances  
MINIMUM CLEARANCES TO COMBUSTIBLES  
Maintain clearances from appliance to  
combustible materials as detailed in Table  
5, with the following exception: When the  
appliance is installed with one side flush  
with a wall, the wall on the other side of the  
appliance must not extend beyond the front  
edge of the appliance. In addition, when the  
applianceisinstalledinthemiddleofaroom,the  
side walls surrounding the appliance must not  
extend beyond the front edge of the appliance.  
See Figure 2 on Page 5.  
Hearth Extension - A hearth extension is not required with this appliance. If a hearth extension is used,  
do not block the lower control compartment access door. Any hearth extension used is for appearance  
only and does not have to conform to standard hearth extension installation requirements.  
Wall Finishes / Surrounds / Mantels  
Note: Combustible wall finish materials and/or surround materials must not be allowed to encroach  
the area defined by the appliance front and back faces (black sheet metal). Never allow combustible  
materials to be positioned in front of or overlapping the appliance front and back faces. See Figure  
58 on Page 32.  
Non-combustible materials, such as surrounds and other appliance trim, may be installed on the  
appliance front and back faces with the following exception: If the optional radiant panels are  
installed, the non-combustible material may cover any portion of the top radiant panel or the air  
gaps surrounding the top radiant panel down to the top edge of eyebrow hood. The material must  
NOT cover any portion of the glass door or louvered panels.  
MINIMUM CLEARANCES Inches (millimeters)  
Vertical installation clearances to combustible mantels vary according to the depth of the mantel. See  
Figure 6. 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.

Notes:  
Step 2. ROUTING GAS LINE  
Proper Sizing of Gas Line  
• All appliances are factory-equipped with a  
flexiblegaslineconnectorand1/2inchshutoff  
valve (see Figure 47 on Page 28).  
Properly size and route the gas supply line  
from the supply regulator to the area where the  
appliance is to be installed per requirements  
outlined in the National Fuel Gas Code, NFPA  
54 - latest edition (USA) or CAN/CSA-B149.1  
- latest edition (Canada).  
Routeagaslinealongtheinsideoftherightside  
framing as shown in Figure 13. Gas lines must  
be routed, constructed and made of materials  
that are in strict accordance with local codes  
and regulations.  
• See Massachusetts Requirements on Page  
4for 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 28).  
• 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 47). Appliances using  
Propane should have a sediment trap at the  
base of the tank.  
Never use galvanized or plastic pipe. Refer  
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  
applianceinvolvesnumerousconsiderationsof  
materials,protection,sizing,locations,controls,  
pressure,sediment,andmore.Certainlynoone

• Checkwithlocalbuildingofficialforlocalcode  
requirements(i.e.arebelowgradepenetrations  
of the gas line allowed?, etc).  
Figure 13 - ROUTE GAS LINE  
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.

Figure 15 -  
These fireplaces must be vented directly to the outside.  
The vent system may not service multiple appliances, and must never  
be connected to a flue serving a solid fuel burning appliance. The vent  
pipe is tested to be run inside an enclosed 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.  
WARNING  
The VENT SEAL CAP must remain securely installed  
on unused vent collar. Failure to do so could result in  
leakage of flue products into living space.  
REMOVE VENT SEAL CAP  
(From the vent that will be used only)  
Installation of Vent Restrictor  
Top Vent - See Figure 14 and Side Vent - See Figure 15  
(Top Vent Installations with Vertical Terminations Only)  
Preparing the Appliance Vent Collar  
A vent restrictor (provided) may be needed with this appliance. If needed,  
install the vent restrictor (provided) in the appliance top flue outlet as  
shown in Figure 16 when vertically terminating the vent system above  
the roof. It may be installed either from inside or outside the appliance,  
in the inner fireplace collar. It is press-fitted in place.  
Each of the appliances' two vent collars are sealed with a seal cap which  
must be removed from the vent collar being used. Refer to Figure 14  
for top vent installations and Figure 15 for side vent installations and  
the following steps to prepare the appropriate collar for use.  
From the vent collar being used, remove the two screws securing the  
vent seal cap. Twist the cap counterclockwise. Pull it away from the  
appliance and discard, along with the piece of insulation.  
Note: The restrictor is included within the firebox.

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/CSA-B149.1 installation code)  
by major building codes. Always consult your  
localcodesforspecificrequirements.Ageneral  
guide to follow is the Gas Vent Rule (refer to

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 avail-  
able (see Table 7 and Page 34 - Item 3). It is  
recommended that you plan the vent lengths  
so that a section joint does not occur within the  
space defined by ceiling joists or roof rafters.  
Refer to the Vent Section Length Chart.

Use a carpenter’s level to measure from a  
constant surface and adjust the support straps  
as necessary.  
I. Install the roof flashing - Extend the vent  
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 - see Figure 26). Nail along  
perimeter to secure flashing or adjust roofing  
to overlap the flashing edges at top and sides  
only and trim where necessary. Seal the top  
and both sides of the flashing with waterproof  
caulking.  
K. Install the vertical termination - The final  
Step involves installation of the SV4.5CGV-1  
Vertical Termination. Extend the vent sections  
to the height as shown in the "Vertical vent  
termination section" (Page 6, Figures 3A and  
3B). The SV4.5CGV-1 Vertical Termination  
(Figure 27) can be installed in the exact same  
fashionasanyotherSecureVentsection. Align  
the termination over the end of the previously  
installedsection, adjustingtheradialalignment  
untilthefourlockingdimplesofthetermination  
are aligned with the inlets of the four incline  
channels of the last vent section. Push the ter-  
mination 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.  
It is important to maintain the required clear-  
ancestocombustibles:1"(25mm)atallsides  
forallverticalruns;and3"(76mm)atthetop,  
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 25.  
J. Install the storm collar - Install the storm

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 direc-  
tion of the next vent run element. Twist elbow  
sections in a clockwise direction only so as  
to avoid the possibility of unlocking any of  
the previously connected vent sections. See

I.Continueinstallationofhorizontal/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.  
See Figure 33. 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

level to measure from a constant surface and  
adjust the support straps as necessary.  
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. It is recom-  
mended that you plan the vent lengths so that  
a section joint does not occur within the space  
definedbyceilingjoists,roofraftersorwallstuds.

E. Attach vent components to each other  
- Other vent sections may be added to the  
previouslyinstalledsectioninaccordancewith  
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)

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.  
IMPORTANT: The vent termination is hot  
whileinoperationandforaperiodoftime  
following the use of the fireplace. Young  
children should be carefully supervised  
when they are in the same area as a hot  
termination. To prevent contact with hot  
surfaces, we recommend the use of a  
Termination Guard. See Page 34. This  
can be purchased at your local dealer.  
Take care to carefully follow the installation instructions for the termination, including  
the use of silicon caulking where required.

Secure Flex™ venting kits and components  
may be used in any venting application in place  
of rigid Secure Vent™ (SV4.5) direct-vent  
components. All restrictions, clearances and  
allowances that pertain to the rigid piping apply  
to the flexible venting. Secure Flex kits may  
notbemodified;also,undernocircumstances  
may separate sections of flex pipe be joined  
together.  
APPLY ONLY MIL-PAC BLACK  
HIGH TEMPERATURE SEALANT  
(Cat. No. 10K81) to the outside  
surface of both collars of the  
adapter (be especially careful to  
fill the grooves of the outer collar  
tobecoveredbytheflexiblepipe)  
and slide flexible pipe over inner  
and outer adapter collars.  
Gear Clamps  
Using adapter (SV4.5RF), Secure Flex kits  
may be added to the end of a vent run made  
up of rigid Secure Vent (SV4.5) vent sections  
provided that doing so does not violate any of  
the venting length, height, routing, horizontal  
to vertical ratio requirements or clearance  
considerations detailed in this manual.

Figure 42  
D. Install Firestop / Spacers at ceilings and walls  
- When Secure Flex penetrates a wall or ceiling,  
a firestop / spacer is required: use the SF4.5 VF  
firestop / spacer for ceilings and the SF4.5 HF  
firestop / spacer for walls. See the appropriate  
sectionsandFiguresshownthroughoutthevent-  
ing section for their installation requirements.  
B. Install the Outer Flex Pipe -  
Align the dimpled end of the adapter over  
the previously installed section or appliance  
collar, adjusting the radial alignment until the  
four locking dimples of the adapter are aligned  
with the inlets of the four incline channels of  
the last vent section or collar. Push on the  
adapter until it fully engages, then twist the  
adapter clockwise running the dimples down  
and along the incline channels until they seat  
at the end of the channels.  
1. Install the large gear clamp loosely around  
the outer flexible vent pipe, push it back out  
of the way.  
2. ApplyabeadofMill-PacBlack(700°F,high  
temperature sealant - Catalog No. 10K81)  
to the outer adapter collar; to the grooves  
of the collar which extend approximately 1  
inch from the end and to the flat surface,  
approximately 1 3/8 inches from the end.  
3. Pull and extend outer flexible vent pipe.  
4. Slidetheouterflexpipeovertheadaptercol-  
lar. Ensure the flexible vent pipe completely  
engages the adapter collar to a distance of  
1³⁄ inches from the end, and that it is free  
from damage or tears.  
5. Slide the gear clamp down and tighten it  
fullytosecuretheflexibleventtotheadapter  
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 connec-  
tion.

TEST ALL CONNECTIONS FOR GAS LEAKS  
(FACTORY AND FIELD):  
Step 8. INSTALLING LOG SET, VOLCANIC  
STONE AND GLOWING EMBERS  
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.  
Inspect the pilot flame.  
WARNING  
Never use an open flame to  
check for leaks.  
WARNING  
• DO NOT attempt to install the  
logsuntiltheapplianceinstal-  
lationhasbeencompleted,the  
gas line connected and tested  
forleaksandtheinitialburner  
operation has been checked  
out.  
Turn on gas supply and test for gas leaks using a  
gas leak test solution (also referred to as bubble  
leak solution).  
Millivolt Appliance Checkout  
Note: Using a soapy water solution is an effec-  
tive 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.  
The pilot flame should be steady, not lifting  
or floating. Flame should be blue in color with  
traces of orange at the outer edge.  
• Thesizeandpositionofthelog  
setwasengineeredtogivethe  
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  
incompletecombustion,soot-  
ing, 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 grate, volcanic stone,  
vermiculite, embers and  
logs.  
• Thisapplianceisnotdesigned  
to burn wood. Any attempt  
to do so could cause irrepa-  
rabledamagetotheappliance  
and prove hazardous to your  
safety.  
• If logs are not installed  
according to the log instal-  
lation instructions, flame  
impingement and improper  
combustion could occur and  
resultinsootand/orexcessive  
productionofcarbonmonoxide  
(CO), a colorless, odorless,  
toxic gas.  
The top 3/8" (10 mm) at the pilot generator  
(thermopile) and the top 1/8" minimum (tip)  
of the quick drop out thermocouple should be  
engulfed in the pilot flame.  
A. Light the appliance (refer to the lighting  
instructionslabelinthecontrolcompartment  
or in the Care and Operation Instructions  
manual).  
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  
sure to rinse off the leak testing solution.  
The flame should project 1" (25 mm) beyond  
the hood at all three ports (Figure 50).  
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).

c. Asafinalcheckforcorrectlogsetplacement,  
check that the four outer notches on the  
underside of the log set fit over the burner  
tines as indicated in Figure 52.  
Install the decorative volcanic stone and  
glowing embers (rockwool):  
FRONT BURNER  
Note: The burners are not identical. Position them so  
that the circular burner ports run as shown. Note  
especially the vertical run of ports relative to the pilot  
burner. Bracket A on the rear burner will interfere  
with the pilot burner if an attempt is made to install  
the rear burner in the front burner’s position.  
Burner / Grate Location Reference  
(see Figures 52 to 54)  
Spread the decorative volcanic stone on the  
simulated brick floor of the firebox around  
the burners to simulate ashes. Maintain a 1/2  
inch (13 mm) gap between the bottom of the  
horizontal grate section and the top of the pile  
of decorative volcanic stone. Place a few quar-  
ter-sized pieces of the glowing ember material  
on the pan burner in front of the burned out  
area on both sides of the log set. The glowing  
embers may touch one another, but should not  
overlap each other.  
Note: If the burners have been removed for  
any reason, rear burner must be installed  
before front burner. See Figures 52 to 54.

Removing Glass Enclosure Panels  
(see Figure 55)  
Step 10. BURNER ADJUSTMENTS  
Step 9. INSTALLATION AND REMOVAL  
OF GLASS DOOR  
Flame Appearance and sooting  
Proper flame appearance is a flame which is  
blueatthebaseandbecomesyellowish-orange  
in the body of the flame.  
1. Remove the top louver assembly by lifting it  
up and pulling it out.  
2. Remove the control compartment access  
door (see removal instructions on Page 28  
- Removing Control Compartment Door).  
3. Locate the two (2) latches at the top of the  
control compartment. To disengage the two  
latches from the bottom vee-flange of the  
glassenclosurepanel, reachforthehandles  
located towards the back of the latches and  
pull the handles down toward the front of  
the appliance.  
WARNING  
When the appliance is first lit, the entire flame  
may be blue and will gradually turn yellowish-  
orangeduringthefirst15minutesofoperation.  
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.  
• Donotattempttosubstitutethe  
materialsusedonthesedoors,  
or replace cracked or broken  
glass.  
• Handlethisglasswithextreme  
care! Glass is susceptible to  
damage – Do not scratch or  
handleroughlywhilereinstall-  
ing the glass door frame.  
• The glass door(s) of this appli-  
ance must only be replaced as  
a complete unit as provided  
by the manufacturer. Do not  
attempt to replace broken,  
crackedorchippedglasssepa-  
rately.  
4. Swing the bottom of the door out and raise  
it slightly to lift the top flange of the door  
frame away from the appliance.  
If the air shutter openings are closed too far,  
sooting may develop. Sooting is indicated by  
black puffs developing at the tips of very long  
orangeflames. Sootingresultsinblackdeposits  
forming on the logs, appliance inside surfaces  
and on exterior surfaces adjacent to the vent  
termination.  
Installing Glass Enclosure Panels  
(see Figure 55)  
1.Visuallyinspectthegasketonthebacksideofthe  
glasspanel.Thegasketsurfacemustbeclean,  
free of irregularities and seated firmly.  
2. Positiontheglassenclosurepanelinfrontof  
thefireboxopeningata45degreeangleand  
engage the top flange over the lip at the top  
of the firebox opening. See Figure 55.  
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.  
4. Reinstall top louver assembly and control  
compartment door see installation instruc-  
tions on Page 28, Reinstalling Control  
Compartment Door).  
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.  
• Do not attempt to touch the  
frontenclosureglasswithyour  
hands while the fireplace is in  
use.  
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.  
WARNING  
Do not operate appliance with  
theglassfrontremoved,cracked  
or broken.  
Top Flange on  
Glass Door  
• Themoreoffsetsintheventsystem,thelarger  
the air shutter opening will need to be.  
• 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  
moreminutestoensurethattheflamenormal-

VERIFY THE PROPER ORIFICE SIZES  
BEFORE INSTALLING THEM.  
FRONT BURNER  
A. Remove the two orifices from the manifold  
and replace them with the ones provided in the  
kit. Table 9 shows the orifice sizes for natural  
and propane models. Figure 62 illustrates the  
orifice. Use pipe joint compound or Teflon tape  
on all pipe fittings before installing (ensure  
propane resistant compounds are used in  
propane applications, do not use pipe joint  
compounds on flare fittings).  
Note: The burners are not identical. Position them so  
that the circular burner ports run as shown. Note  
especially the vertical run of ports relative to the pilot  
burner. Bracket A on the rear burner will interfere with  
the pilot burner if an attempt is made to install the  
rear burner in the front burner’s position.
