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.

These fireplaces must be vented directly
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

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.

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
the incline channels until they seat at the end of
thechannels. TheunitizeddesignoftheSecure
Vent™ components will engage and seal both

procedure. Sealant and securing screws are
not required.
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
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.
G. Support the vertical run sections -
See Section E on Page 15.
H.Changeventdirection -Attransitionfromor
toahorizontal/inclinedrun,installtheSV4.5E45

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.

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.

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

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-
orangeduringthefirst15minutesofoperation.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
orangeflames. 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

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

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.

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.
