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).

Thesedirectventappliancesareuniquelysuited  
for installations requiring a utility shelf posi-  
tioneddirectlyabovethefireplace.Utilityshelves  
like these are commonly used for locating tele-  
vision sets and decorative plants.  
These appliances must not be connected to a  
chimney or flue serving a separate solid fuel  
burning appliance.

under water. Immediately call a qualified,  
professional service technician to inspect the  
appliance and to replace any parts of the con-  
trol system and any gas control which have  
been under water.  
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

Both these vertical vent systems terminate  
through the roof. In the USA, the minimum  
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.

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

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

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/  
inclinedventrunsusingconventionalplumbers  
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 carpenters  
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

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

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.

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  
wall thicknesses greater than that shown in  
Figure38,refertoTable3onpage18.Thistable

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.  
See the appropriate sections and figures  
shown throughout the venting section for  
their installation requirements.  
Flexible Vent Section  
Attach the flexible vent to the adapter as  
follows (also see Figure 47 ):  
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 inch 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  
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  
inner collar approximately ³⁄₄ inch from the  
end of the flex.

Radius Minimum  
Figure 48  
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.  
6.Installthreescrews120degreesapartthrough  
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.

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.  
Note:ThegasvalveON/OFFswitchisshownin  
Figure 51, or 52 on page 23. It is integral with  
the gas valve and should be set to the ON  
position.  
3. Remove the junction box/outlet receptacle  
assembly by removing the securing screw at  
thefrontrightcorneroftheunit. SeeFigure50.  
(The left and right designations used here are  
reversed in CDCR applications.)  
A. Millivolt Wiring (See Figure 49 ) –  
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 thermo-  
stat is selected mount it in a convenient loca-  
tion 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 oper-  
ated 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 in the bottom compartment of the  
unit) together as shown in Figure 49.  
IMPORTANT: Ground supply lead must be  
connected to the wire attached to the green  
ground screw located on the outlet recep-  
tacle. See Figures 51, and 52 on page 23.

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:turnONtheunit-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  
ONposition.  
C. Brush all joints and connections with the  
soapywatersolutiontocheckforleaks.Ifbubbles  
are formed, or gas odor is detected, turn the gas  
control knob to the OFFposition. 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.

Allow the burner to operate for at least 15  
minutes. Observe the flame continuously. If it

adjust the air shutter by rotating the adjust-  
ment rod until the flame appearance is as  
desired.

Flame Appearance and sooting  
Propane models may exhibit a flame pattern  
that may candle or appear stringy. If this is  
problematic or persists as the appliance is  
continually operated, adjust the air shutter  
closedasdescribedinthepreviousparagraphs.

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.  
1. Visually inspect the gasket on the backside  
of the panels. The gasket surface must be  
clean, free of irregularities and seated firmly.

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.
