B-VENT GAS FIREPLACES • MODELS SLBV-35, SLBV-40 • CARE AND OPERATION INSTRUCTIONS
IMPORTANT: Do NOT assume your fire-
place has a complete supplemental com-
bustion air system, and do NOT operate
the Outside Air Control Lever unless you
have verified with your dealer or distribu-
tor that a complete system is in place.
The hand-operated outside air control lever is
located on the lower LEFT side of the fireplace
opening. See
Figure 5
.
To open the outside air shutter, open the bot
-
tom control access panel, reach into the control
compartment, and pull the outside air control
lever all the way out. The outside air shutter
should be fully open when the fireplace is in use
and completely closed when the fireplace is not
being used. Closing it when not in use will greatly
reduce the amount of outside cold air entering
the dwelling through the fireplace.
Figure 5
WARNING
Do not operate the shutoff lever
unless a complete outside com-
bustion air system has been
installed with your appliance.
TO LIGHT YOUR APPLIANCE IN A POWER
OUTAGE:
• Confirm batteries installed in battery
pack.
• Turn unit mounted switch or wall switch
to the ON Position.
• Unit should spark at pilot and light.
NOTE: If no spark, replace batteries.
• Operate Normally.
Note:
Install fresh batteries in the battery holder
prior to the start of burn season, so the
fireplace can automatically switch to
battery power (4 “AA” batteries) in the
event of a power outage.

Appliance Controls
Operation of millivolt and electronic gas
control systems differs. Before lighting and
operating your appliance, determine whether
you have a millivolt or electronic appliance,
and then familiarize yourself with the location of
the
Gas Control Valve
and
Gas Shut-Off Valve
on your specific appliance.
• For general control location, see
Figure 1
.
•
For
MILLIVOLT appliances, see
Figure 3
•
For
ELECTRONIC appliances, see
Figure 4
Lighting the Appliance
• Detailed MILLIVOLT
appliance lighting
instructions are on
Pages 22 and 23
and
also on the label attached to the gas
control valve
.
• Detailed ELECTRONIC
appliance lighting
instructions are on
Pages 24 and 25
and
also on the label attached to the
gas control valve
. Also see “Lighting
an Electronic Appliance During a Power
Outage,” below.
ON/OFF Control
Available ON/OFF control options for both
MILLIVOLT and ELECTRONIC
models
include a
unit-mounted ON/OFF switch (shown in
Figure
1
)
, a wall switch, or a remote control system.
See the “Accessory Components” section in
this manual for details.
Note: To prevent excessive resistance in
burner circuit (which can cause burner op-
eration problems), wire only one burner
control switch to the valve.
Adjusting Flame Height
After lighting the appliance, rotate the Flame
Height Adjustment Knob
to adjust the flame in
a variable range from “LOW” to “HI” (manual
adjustment only; no remote options).

CONTROLS FOR OPTIONAL
OUTSIDE COMBUSTION AIR KIT
An optional outside combustion air system
may be used with these appliances to provide
supplemental combustion air from outside the
home during appliance operation. If used, the
outside combustion air kit must be installed
before the fireplace is framed and enclosed in
the finished wall.
The
Outside Air Control Lever
for this type of
system is standard on all models (see
Figure
5
);
however, do NOT operate the Outside Air
Control Lever if the complete system is NOT
installed
.
When a complete outside supplemental com-
bustion air system is installed, the installer will
remove the securing screw from the control
lever on the LEFT side of the fireplace opening
(see
Figure 5
).
If the securing screw has NOT been removed,
and you have reason to believe your fireplace
has a
complete
outside supplemental combus-
tion air system, contact your dealer or distribu
-
tor to have your appliance inspected.
