Never use galvanized or plastic pipe. Refer to  
Table 6 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.  
Notes:  
Step 2. ROUTING GAS LINE  
• All appliances are factory-equipped with a  
flexiblegaslineconnectorand1/2inchshutoff  
valve (see Figure 40 on Pagec 26).  
• 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).  
Apipejointcompoundratedforgasshouldbe  
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. Appliances using Propane should  
have a sediment trap at the base of the tank.  
• Check with local building official for local code  
requirements(i.e.arebelowgradepenetrations  
of the gas line allowed?, etc).  
Route a 1/2" (13 mm) gas line to the left side  
of the appliance as shown in Figure 15. Gas  
lines must be routed, constructed and made  
of materials that are in strict accordance with  
local codes and regulations. All appliances  
are factory-equipped with a flexible gas line  
connector and 1/2 inch shutoff valve. (See  
Step 6 on Page 26).  
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 appli-  
ance. Installing a gas supply line from the fuel  
supply to the appliance involves numerous  
considerations of materials, protection, siz-  
ing, locations, controls, pressure, sediment,  
and more. Certainly no one unfamiliar and  
unqualified should attempt sizing or installing  
gas piping.

IMPORTANT:Ifpropaneisused, beawarethat  
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.

Installation of Vent Restrictor  
Step 3. INSTALL THE VENT SYSTEM  
General Information  
Vent Restrictor Installation  
(Top Vent)  
A vent restrictor may be needed with this  
appliance. The restrictor is installed in the  
appliance top flue outlet as shown in Figure  
16, either before adding vent, from above, or  
after installation of vent from below, within the  
firebox. The restrictor is self securing through  
a positive friction fit.  
A vent restrictor may be needed when vertical-  
ly terminating the vent system above the roof  
(when using the appliance top vent), install  
vent restrictor in the top vent of the fireplace  
outlet on all SLDVT series models. If needed,  
install the restrictor orientated as shown,  
either from inside or outside the unit,in the  
inner fireplace collar.  
These instructions should be used as a  
guideline and do not supersede local codes  
in any way. Install venting according to local  
codes,theseinstructions,thecurrentNational  
Fuel Gas Code (ANSI-Z223.1) in the USA or  
the current standards of CAN/CSA-B149.1  
in Canada.  
Determine the venting for the appliance. If the  
vent run will include at least 8 feet of vertical  
rise,theninstalltherestrictorintheappliance  
collar before connecting any vent (Refer to  
Figure 16). Place the restrictor inside the ap-  
pliance vent collar and press in place.

to the outside.  
Select Venting System - Horizontal or Vertical  
With the appliance secured in framing, de-  
termine vent routing and identify the exterior  
termination location. The following sections  
describevertical(roof)andhorizontal(exterior  
wall) vent applications. Refer to the section  
relating to your installation. A list of approved  
venting components are shown on Pages 36  
and 37.  
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.

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

Tables on Pages 16 and 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

available in 90° and 45° configurations. Refer  
to Figure 21 on Page 15 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.

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/spacer must be installed on the top  
side of the joist.  
Align the dimple (4 places) of the  
upper vent section with the opening  
of the locking incline channel on

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

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 (H3907) may be used  
to obtain the required clearances indicated  
here. See installation accessories Pages 35  
and 36. The gap between the vent pipe and a  
vertical firestop can be sealed with non-com-  
bustible caulking.

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.  
j. Install the storm collar - Install the storm  
collar, supplied with the flashing, over the  
vent/flashing joint (see Figure 23). Loosen  
the storm collar screw. Slide collar down until  
it meets the top of the flashing. Tighten the ad-  
justing screw. Apply non-combustible caulking  
or mastic around the circumference of the joint  
to provide a water tight seal.  
If the vent system extends more than 5 feet  
(1.5m)abovetheroofashing, stabilizersmay  
be necessary. Additional screws may be used

TERMINATION SYSTEM  
Secure Vent SV4.5 direct-vent system compo-  
nents are unitized concentric pipe components  
featuring positive twist lock connection, (refer  
to Figure 19 on Page 14). 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.  
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.  
See Figure 28 on Page 18, and Figures 29  
through 34 on Pages 19 through 22 and their  
associated HorizontalVentTablewhichillustrate  
the various horizontal venting configurations  
that are possible for use with these appliances.  
Secure Vent™ pipe applications are shown in  
these Figures; Secure Flex pipe may also be  
used. A HorizontalVentTablesummarizeseach  
system’s minimum and maximum vertical and  
horizontal length values that can be used to  
design and install the vent components in a  
variety of applications.  
B. Frame exterior wall opening -  
Locate the center of the vent outlet on  
the exterior wall according to the dimen-  
sions shown in Figure 13 on Page 10. Cut  
and/or frame an opening, 10-1/2" x 12 1/8"  
(267 mm x 308mm) inside dimensions, about  
this center.  
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"  
(572mm),34-1/2"(876mm)and46-1/2"(1181  
mm) net section lengths are available. It is  
recommended that you plan the vent lengths  
so that a joint does not occur at the intersection  
of ceiling or roof joists. Make allowances for  
elbows as indicated in Figure 21.

D. Attach vent components to appliance - To  
attach a vent component to the appliance collar,  
alignthedimpledendoverthecollar,adjustingthe  
radialalignmentuntilthefourlockingdimplesare  
aligned with the inlets of the four incline channels  
on the collar (see Figure 19 on Page 14).  
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 19 on Page 14.  
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 possibility of unlocking any  
ofthepreviouslyconnectedventsections(see  
Figure 19 on Page 14).  
Push the vent component against the collar  
until it fully engages, then twist the component  
clockwise,runningthedimplesdownandalong

procedure. Sealant and securing screws are  
not required.  
F. Install firestop/spacer at ceiling -  
WhenusingSecureVent,useSV4.5VFrestop/  
spaceratceilingjoists;whenusingSecureFlex,  
use SF4.5VF firestop/spacer. If there is living  
spaceabovetheceilinglevel,therestop/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.  
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  
every5ft.(1.52m)alonghorizontal/inclinedvent  
runs using conventional plumber’s tape.  
See Figure 28. 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.  
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 pre-  
viously 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,  
adjustingtheradialalignmentuntilthefourlock-  
ingdimplesarealignedwiththeinletsofthefour  
incline channels of the previous section.  
Remember to maintain 1" (25 mm) clearance  
to combustibles, framing members, and attic  
or ceiling insulation when running vertical  
chimney sections.  
It is important to maintain the required clear-  
ancestocombustibles:1"(25mm)atallsides  
forallverticalruns;and 3" (76mm)atthetop,  
1" (25 mm) at sides, and 1" (25 mm) at the  
bottom for all horizontal/inclined runs.

Horizontal terminations have been designed to perform in a wide range of weather condi-  
tions. Our terminations meet or exceed industry standards.  
IMPORTANT: The vent termination is hot  
while in operation and for a period of  
time following the use of the fireplace.  
To prevent contact with hot surfaces,  
we recommend the use of a Termina-  
tion Guard. See Page 37. This can be  
purchased at your local dealer.  
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.

Step 6. CONNECTING GAS LINE  
GAS CONNECTION  
Optional Gas Flex Line Connector  
All codes require a shut-off valve mounted  
in the supply line. The orientation of the  
shut-off valve should face the front. Figure  
40 illustrates two methods for connecting the  
gas supply. A sediment trap is recommended  
in the gas piping within the home to prevent  
moisture and debris in the line from damaging  
the valve.

These appliances are equipped with a gas flex  
lineforuseinconnectingtheunittothegasline.  
See Figure 40 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.

The panel is mounted on supporting tabs at  
the extreme right and left hand sides. Engage  
the tabs into the reliefs in the panel.  
The millivolt and electronic control valve has a  
3/8" (10mm) NPT thread inlet port.

Gas line connection may be performed largely  
outside of the confines of the control compart-  
ment and without having to enter the firebox  
behind the glass. Proceed as follows:  
Figure 41  
Acquire the shut-off valve and gas lex line and  
pull the assembly forward out of the compart-  
ment. Separate the shut-off valve from the gas  
flex line. Determine the length of pipe needed  
to route the gas line from the last fitting (shown  
in Figure 15 on Page 11) to a point within the  
control compartment that will allow the shut-  
off valve to be easily attached by hand to the  
gas flex line.  
Refer to Figure 42 and insert the last length  
of gas pipe with its attached shut-off valve  
into the lower control compartment, and pass  
it through the gas line access hole on the left  
side of the appliance outer wrapper.  
Important: Turn the last piece of gas pipe in  
the last fitting until the shut-off valve is posi-  
tioned in a way that allows the shut-off valve  
handle to be accessed in the lower control  
compartment, easily operated throughout its  
full range of motion.  
Using appropriate materials for the gas type,  
thread the last length of pipe into the end of the  
gas vent run and tighten in place using a pipe  
wrench external to the appliance between the  
appliance outer wrapper and the framing.  
Bring the flex line to the shutoff valve by hand  
and align the flare fittings. Tighten the fittings  
by hand, and then use wrench to tighten com-  
pletely, 1/4 turn at a time.  
Using pipe-dressing materials appropriate for  
the gas type, securely affix the shut-off valve  
to this determined pipe length at a convenient  
location outside of the appliance lower control  
compartment.

3. Pull the bottom of the door out a few inches  
and grasp it on the right and left. Gently lift  
to release the door from its channel above  
the door. Pull the door forward.  
4. Retrieve the glass door. Visually inspect the  
gasket on the backside of the frame. Gasket  
surface must be clean, free of irregularities  
and seated firmly.  
5. Inspect the gasket for defects. Insure it is  
properly located. Make sure the bead is not  
rolled up into the channel at the top of the  
door, but remains flat against the top of the  
glass (see Figure 50).  
6. Position the door in front of the firebox  
opening with the bottom of the door held  
away from the fireplace (Figure 50). Hook  
the top flange of the door frame over the top  
of the firebox frame.  
7. Let the bottom of the door frame swing  
gently in towards the fireplace ensuring  
that the gasket seats evenly as the door  
frame draws shut. Fasten the two latches  
located underneath the firebox floor to the  
door's vee-flange. Close both the latches  
securely.

Step 10. BURNER ADjUSTMENTS  
Flame Appearance and sooting  
Proper flame appearance is a flame which is  
blueatthebaseandbecomesyellowish-orange  
in the body of the flame.  
WARNING  
Donotattempttosubstitutethe  
materialsusedonthesedoors,  
or replace cracked or broken  
glass.  
When the appliance is first lit, the entire flame  
may be blue and will gradually turn yellowish-  
orangeduringtherst15minutesofoperation.If  
the flame remains blue, or if the flame is orange  
withevidenceofsooting(blacktip),theairshut-  
ter opening may need to be adjusted.  
• 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.  
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  
orangeames. Sootingresultsinblackdeposits  
forming on the logs, appliance inside surfaces  
and on exterior surfaces adjacent to the vent  
termination.  
Sooting is caused by incomplete combustion  
in the flames and lack of combustion air enter-  
ing the air shutter opening. To achieve a warm  
yellowish-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.

Standoffs  
AVERTISSEMENT  
• 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.

Burner Air Shutter Adjustment Procedure  
WARNINGS  
Air shutter adjustment should only be performed  
by a qualified professional service technician.  
Ensure front glass panel are in place and sealed  
during adjustment.  
CAUTIONS  
Soot will be produced if the air shutter is closed  
too much. Any damage due to sooting resulting  
from improperly setting the air shutter is not  
covered under the warranty.  
Theairshutterdoorandnearbyappliancesurfaces  
are hot. Exercise caution to avoid injury while  
adjusting flame appearance.  
Figure 52 - Burner Flame Appearance Model SLDVT-40  
1. Locate adjustment rod and adjust air shutter to the standard set-  
ting as shown in Figure 54 (adjustment rod is located in the lower  
control compartment).  
Note: Move the adjustment rod down to decrease air and up to  
increase.  
2. Light appliance (follow lighting procedure on lighting label in con-  
trol compartment or see the Care and Operation manual).  
3. Allow the burner to operate for at least 15 minutes while observing  
the flame continuously to ensure that the proper flame appearance has  
been achieved (see Figures51, 52 or 53 ). If the following conditions  
are present, adjust accordingly.  
• If flame appears weak or sooty, adjust the air shutter, incremen-  
tally, to a more open position until the proper flame appearance is  
achieved.  
Figure 53 - Burner Flame Appearance Model SLDVT-45  
• If flame stays lowered blue, adjust the air shutter, incrementally, to a  
more closed position until the proper flame appearance is achieved.  
4. Leave the control knob (off/pilot/on) in the ON position and the  
burner OFF/ON switch OFF (and remote switches, if applicable).  
5. When satisfied that the burner flame appearance is normal, re-  
install the lower control compartment door then proceed to finish the  
installation.
