installed before removing the securing screw
allowing the movement of the combustion air
actuator arm (see Step 5 on Page 14).
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
groundlevel. Gaslineholesandotheropenings
should be caulked or stuffed with unfaced
fiberglass insulation. Check local codes for
additional requirements.
In selecting the location, the aesthetic and
functional use of the appliance are primary
concerns. However, vent system routing to
the exterior and access to the fuel supply are
also important.
Be aware that this is a heat-producing ap-
pliance. Objects placed above the unit are
exposed to elevated temperatures.
Due to high temperatures, the appliance
should be located out of traffic and away from
furniture and draperies (Figure 3).
The appliance should be mounted on a fully
supported base extending the full width and
depth of the unit. The appliance may be located
onornearconventionalconstructionmaterials.
However, if installed on combustible materials,
such as carpeting, vinyl tile, etc., a metal or
woodbarriercoveringtheentirebottomsurface
must be used.
En raison des températures élevées,
l’appareil devrait être installé dans un
endroit où il y a peu de circulation et loin
du mobilier et des tentures (Figure 3).
If the fireplace is being installed on a cement
slab in cold climates, a sheet of plywood or
other raised, insulated platform can be placed
underneath to prevent cold transfer to the
fireplace and into the room. It also may help
to sheetrock the inside surfaces and/or tape
for maximum air tightness.
The location should also be free of electrical,
plumbing or other heating/air conditioning
ducting.
These appliances may be used for bedroom
installationsintheUnitedStatesandarelisted
accordingly. Theseunitsmaynotbeinstalled

Right side requirements are the same.)
NOTE: Each installation is unique and may
result in variations to these steps.
Step 1. Construct Appliance
framing
NOTE: The nailing flanges, combustible
members, and screw heads in areas directly
adjacent to the nailing flanges are EXEMPT
from the 1/2” clearance to combustible
requirements for the firebox outer wrapper.
Step 1. (Pages 8–10) Construct the appliance
framing.
Position the appliance within the
framing and secure with nailing
brackets.
Frame the appliance as illustrated in Figures
8-1 and 8-2. All framing details must allow for
a minimum clearance to combustible framing
members as shown in Table 6, Page 7.
Combustible framing may be in direct contact
with the nailing flanges and may be located
closer than 1/2” from screw heads and the
firebox wrapper in areas adjacent to the
nailing flanges.
IMPORTANT! Bend up the appropri-
ate top standoff spacers for the
drywall/finish material thickness to
be used (see Figure 7). Bend up the
outer pair for 1/2" materials and the
inner pair for 5/8" materials.
If the appliance is to be elevated above floor
level, a solid continuous platform must be
constructed below the appliance.
Frame the opening to the exact dimensions
specified in the framing details in this manual.
Headers may be in direct contact with the appli-
ance top standoff spacers when they are bent
up vertically, maintaining the 3" clearance to
the fireplace top, but must not be supported
by them or notched to fit around them. All
construction above the appliance must be
self-supporting. DO NOT use the appliance
for structural support.
Bend up the outer pair for 1/2" ma-
terials and the inner pair for 5/8"
materials.

Note:
Step 2. Route the Gas Line
WARNING
• All appliances are factory-equipped with
a flexible gas line connector and 1/2 inch
shutoff valve (see Figure 17 on Page 15).
Route a 1/2" (13 mm) gas line to either side
of the appliance (left side routing is shown
in Figure 9 ). Gas lines must be routed, con-
structed,andmadeofmaterialsthatareinstrict
accordance with local codes and regulations.
Allappliancesarefactory-equippedwithaflex-
ible gas line connector and 1/2-inch shutoff
valve. (See Step 6 on Page 15.)
Sharp Edges.
WatchYourFingers!
• See Massachusetts Requirements on Page
4 for additional requirements for installa-
tions in the state of Massachusetts in the
USA.
WARNING: EDGES OF SHEET METAL ARE
SHARP! WEAR PROTECTIVE GLOVES AND USE
EXTREME CARE WHEN HANDLING.
• The gas supply line should NOT be con-
nected to the appliance until Step 6 on Page
15).
Required tools:
Left Side Front
Corner of Fireplace
Framing
• Sheet Metal-resistant Gloves
• Tin Snips
• A pipe joint compound rated for gas should
be used on the threaded joints. Ensure that
propane-resistant compounds are used in
propane applications. Be very careful that
the pipe compound does not get inside the
pipe.
1. Using tin snips, cut the three connecting
points securing the slug to the three tabs
in the flue collar (as shown in Figure 10a),
and remove the slug.
Pipe Coupling
(Recommended)
• 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.
Carefully dispose of slug in an appropriate
container.

NOTE: Gas line can be routed to either
side. Reverse this illustration if routing
to right side.
IMPORTANT: If propane is used, be aware that
if the tank size is too small (i.e., under 100 lbs
if this is the only gas appliance in the dwell-
ing; ref. NPFA 58), there may be pressure loss
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.
Also see Figures 8-1 and 8-2.
Figure 9: Route Gas Line
Proper Sizing of Gas Line
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).
Step 3. Install Venting System
and Exterior Termination
Figure 10a
These instructions should be used as a
guideline and do not supercede local codes
in any way.
Never use galvanized or plastic pipe. Gas lines
must be routed, constructed and made of ma-
terials that are in strict accordance with local
codes and regulations.
2. Connect the proper size Type B-vent system
to the fireplace flue collar by bending up the
three tabs and securing with three sheet
metal screws (No. 8 or larger) bend up tabs.
See Figure 10b. Then install the remainder
of the Type B-vent to the outside.
Installventingaccordingtolocalcodes,these
instructions, the current National fuel Gas
Code in the USA (ANSI-z223.1) or the current
standards in Canada (CAN/CSA-B149.1).
IMPORTANT: It is critical that a licensed
installer perform this step strictly per
NFPA.
Type B-Vent
SLBV-35 and SLBV-40 series fireplaces must
be vertically vented using listed type-B,
double-walled vent pipe with the proper
diameter (as listed below) and a listed vent
termination.
SLBV-35 models: 4 in. (102 mm)
SLBV-40 models: 5 in. (127 mm)
We recommend that a qualified, licensed
plumber or gas fitter be hired to correctly size
and route the gas supply line to the appliance.

Operation
The pilot flame should be steady, not lifting
or floating. Flame should be blue in color with
traces of orange at the outer edge.
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.
WARNING
Never use an open flame to
check for leaks.
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.
With gas line installed run initial system check-
outbeforeclosingupthefrontoftheunit. Follow
the pilot lighting instructions provided in the
Care and Operation Instructions manual. For
piezo igniter location, see Figure 17 (millivolt
appliances only).
Turn on gas supply and test for gas leaks, us-
ing a gas leak test solution (also referred to as
bubble leak solution).
The flame should project 1" (25 mm) beyond
the hood at all three ports (see Figure 19).
Replace logs if removed for pilot inspection.
Note: Using a soapy water solution is an
effective leak test solution but it is not recom-
mended, because the soap residue that is left
on the pipes/fittings can result in corrosion
over time.
To light the burner; turn “ON” the remote wall
switch and rotate the gas valve control knob
counterclockwise to the “ON” position (“ON”
will be at the top side of the valve).
Note: Lighting Instructions are also found on
the literature tag tied to the gas piping next
to the gas valve. To access the tag, open the
lower control compartment door by pulling

placement is critical to prevent sooting.
Logs should be placed in the gaps between
the flame peaks and should be positioned so
they do not impinge the flames. Follow the
log placement instructions exactly.
Note: The bag of Glowing Embers
contains enough rockwool for several
applications; therefore, do not use the
entire bag at one time. For best glow-
ing effect, replace the ember material
annually.

WARNING
Flame Appearance and Sooting
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.

• Handle this glass with extreme
care! Glass is susceptible to
damage – do not scratch or

• 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, cracked or
chipped glass separately.
Removing the Glass Enclosure Panel
1. Refer to Figure 25. To access the spring
latches securing the front glass enclosure
panel, open the lower control compartment
door by lifting and pulling the bottom panel
forward.
Iftheairshutteropeningisclosedtoofar,sooting
maydevelop. Sootingisindicatedbyblackpuffs

Sootingresultsinblackdepositsformingonthe
logs, appliance inside surfaces and on exterior
surfaces adjacent to the vent termination.
2. Pull the spring latches forward and down to
release them from the lower door channel.
3. Pull the bottom of the glass enclosure panel
out a few inches, and grasp it on the right
and left sides. Gently lift to release the panel
from its upper channel, and then pull the
enclosure panel forward to remove it.
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 front
enclosure glass with your hands
while the fireplace is in use.
4. Visually inspect the gasket on the backside
of the enclosure panel frame. The gasket
surface must be clean, free of irregularities,
and firmly seated.
WARNING
do not operate appliance with
theglassfrontremoved,cracked
or broken.
Air Shutter Adjustment Guidelines
This appliance is designed to operate only
when the glass enclosure panel is installed.
Do NOT remove the glass enclosure panel un-
less necessary (e.g., to gain access to compo-
nents within the firebox or to clean the glass).
• 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.
