4 Safety Precautions
© Travis Industries 4/22/21 - 1514 PB 24 CF GSB2 Operation
IF YOU SMELL GAS:
* Do not light any appliance
* Extinguish any open flame
* Do not touch any electrical switch or plug or unplug anything
* Open windows and vacate building
* Call gas supplier from neighbor's house, if not reached, call fire department
This unit must be installed by a qualified installer to prevent the possibility of an explosion.
Your dealer will know the requirements in your area and can inform you of those people
considered qualified. The room heater should be inspected and cleaned before use and at
least annually by a qualified service person. More frequent cleaning may be required due
to excessive lint from carpeting, bedding material, etc.
The instructions in this manual must be strictly adhered to. Do not use makeshift methods
or compromise in the installation. Improper installation will void the warranty and safety
listing.
This heater is either approved for natural gas (NG) or for propane (LP). Burning
the incorrect fuel will void the warranty and safety listing and may cause an
extreme safety hazard. Direct questions about the type of fuel used to your dealer.
Check for a label on the flame adjust knob on the gas control valve (this is the best
place to check). You may also check for a label on the gas control valve body.
Contact your local building
officials to obtain a permit and
information on any installation
restrictions or inspection
requirements in your area.
Notify your insurance company
of this heater as well.
If the flame becomes sooty, dark
orange in color, or extremely tall,
do not operate the heater. Call
your dealer and arrange for
proper servicing.
It is imperative that control
compartments, screens, or
circulating air passageways of
the heater be kept clean and
free of obstructions. These
areas provide the air necessary
for safe operation.
Do not operate the heater if it is
not operating properly in any
fashion or if you are uncertain.
Call your dealer for a full
explanation of your heater and
what to expect.
Do not store or use gasoline or
other flammable liquids in the
vicinity of this heater.
Do not operate if any portion of
the heater was submerged in
water or if any corrosion occurs.
Immediately call a qualified
service technician to inspect the
appliance and to replace any part
of the control system and any
gas control that has been under
water.

Safety Precautions 5
© Travis Industries 4/22/21 - 1514 PB 24 CF GSB2 Operation
Do not place clothing or other
flammable items on or near the
heater. Because this heater can
be controlled by a thermostat
there is a possibility of the
heater turning on and igniting
any items placed on or near it.
Light the heater using the built-in
igniter. Do not use matches or
any other external device to light
your heater.
Allow the heater to cool before
carrying out any maintenance or
cleaning.
The viewing glass should be
opened only for conducting
service. Do not operate with
cracked, broken, or removed
glass.
Any safety screen or guard
removed for servicing must be
replaced prior to operating the
heater.
Never remove, replace, modify or
substitute any part of the heater
unless instructions are given in
this manual. All other work must
be done by a trained technician.
Don't modify or replace orifices.
Operate the heater according to
the instructions included in this
manual.
If the main burners do not start
correctly turn the gas off at the
gas control valve and call your
dealer for service.
Instruct everyone in the house
how to shut gas off to the
appliance and at the gas main
shutoff valve. The gas main
shutoff valve is usually next to
the gas meter or propane tank
and requires a wrench to shut off.
This unit is not for use with solid
fuel
Do not place anything inside the
firebox (except the crushed
glass).
If any component becomes
damaged, replace with Travis
Industries components.
Do not throw this manual away.
This manual has important
operating and maintenance
instructions that you will need at
a later time. Always follow the
instructions in this manual.
Children and adults should be
alerted to the hazards of high
surface temperature and should
stay away to avoid burns or
clothing ignition. Young children
should be supervised when they
are in the same room as the
heater.
Travis Industries, Inc. grants
no warranty, implied or stated,
for the installation or
maintenance of your heater,
and assumes no responsibility
of any consequential
damage(s).

6 Operation
© Travis Industries 4/22/21 - 1514 PB 24 CF GSB2 Operation
Before You Begin
 Read this entire manual before you use your new fireplace (especially the section "Safety
Precautions" on pages 4 & 5). Failure to follow the instructions may result in property damage, bodily
injury, or even death.
Location of Controls
There is a door on the lower portion of the screen assembly to provide access to the manual controls on
the fireplace. The door is held closed by two magnets. Open the door by gently pulling outward on the
upper portion of the lower trim.
On/Off Switch This control is used to turn the heater on and off.
Gas Control Knob This knob is used to control gas to the heater and for starting the pilot. There
are three positions, ON, OFF, & PILOT. The pointer to the left of the knob
indicates the position this knob is in.
Flame Adjust Knob This knob controls the flame height from low ("LO") to high ("HI"). The
pointer above the knob points to the position this knob is in.
Continuous Pilot --
GreenSmart Pilot
This switch controls how the pilot flame works. See
the section “Continuous
Pilot / GreenSmart Pilot” for det
ails.
Optional Remote Receiver The receiver is used in conjunction with the optional remote thermostat. It is
used to control the remote and replaces the on/off switch for direct operation.
Optional Blower Dial This knob controls the speed of the internal convection blower that pushes
the heated air into the room.
Optional Light Dial This dial controls the brightness of the optional accent lights (if applicable).

Operation 7
© Travis Industries 4/22/21 - 1514 PB 24 CF GSB2 Operation
Starting the Fireplace for the First Time
 Burn the heater at a high setting with the blower off for an extended period (up to 48 hours). This will
cure the painted surfaces. Fumes from the paint curing and oil burning off the steel will occur. This
is normal. We recommend opening a window to vent the room.
 Condensation may appear on the glass each time you start the fireplace - this is normal.
 Blue Flames will occur on the fireplace when it first comes on. After fifteen minutes the flames will
turn a more realistic yellow and orange color.
 Certain installations use a remote, thermostat, or wall switch to turn the fireplace on and off. If this is
the case, leave the ON/OFF switch "ON".
 Verify the power backup and control light batteries are installed.
Turning the Fireplace On and Off
 Do not place any combustible items on top of or directly in front of the heater, even temporarily. The
optional thermostat may start the heater causing a combustible item to ignite.
 If the heater turns on and off frequently while using the thermostat, you may want to adjust the flame
height down until it produces just enough heat needed.

8 Operation

Adjusting the Flame Height
This fireplace has an adjustable flame to tailor the look and
heat output to your specific needs. It is adjusted by turning the
flame adjust knob.
Adjusting the Blower Speed (Optional)
The optional blower helps transfer heat from the heater
into the room. It will not turn on until the heater is up to
temperature (approximately 10 minutes after starting).
See the illustration to the right for instructions on adjusting
the blower speed.
Continuous Pilot / GreenSmart™ Pilot Switch
This fireplace may run with the pilot continuously running or in GreenSmart (intermittent) mode. For most
homeowners, the GreenSmart mode is preferred (this saves fuel, doesn’t give off un-needed heat).
However, in some situations the homeowner may prefer to switch the fireplace to continuous pilot. The
most typical reasons for switching to continuous pilot are:
 Very Cold Conditions – in very cold conditions you may
notice that the burner does not light quickly, and the flames
lift off the burner. If this is situation, we recommend you
switch to continuous pilot. This will create a slight draft in the
vent, allowing for the burner to light quickly and draft
correctly.
 Excessive Condensation on Glass after Startup – certain
installations may encounter excessive fogging on the window
after startup (not just the first time the fireplace was started).
This is an aesthetic condition that may be remedied by
switching the fireplace to continuous pilot.
 Cold Glass or Fireplace Front – in very cold conditions you
may notice that the fireplace front and glass become very
cold. To remedy this, switch the fireplace to continuous pilot.
 Frequent On / Off Operation – if you are frequently turning the
fireplace on and off, you may wish to leave it in continuous pilot.
This allows the burner to turn on more quickly, without pilot ignition
delay.

Operation 9

Starting the Heater for the First Time
 Burn the heater at a low setting with the blower off for an extended period (up to 48 hours). This will
cure the painted surfaces. Fumes from the paint curing and oil burning off the steel will occur. This is
normal. We recommend opening a window to vent the room.
 Condensation may appear on the glass each time you start the heater - this is normal.
 Blue Flames will occur on the heater when it first comes on. After fifteen minutes the flames will turn
a more realistic yellow and orange color.
 Verify the batteries are installed.
Adjusting the Blower Speed (Optional)
The optional blower helps transfer heat from the heater into the room. It will not turn on until the heater is
up to temperature (approximately 10 minutes after starting). See page 8 for details on adjusting the
blower speed.
Normal Operating Odors
This appliance has several areas that reach high temperatures. Dust or other particles on these areas
may burn and create an odor. This is normal during start-up. You may notice the smell is more acute if
the appliance was left idle for a long period.
Power Outages
Four AA batteries are used as a power backup for the fireplace in case the household (AC) power goes
out. These batteries must be inserted into battery holder (or remove receiver is using the optional GS
thermostatic remote). The fireplace controller will beep once these batteries start to go dead. Replace
batteries before each heating season to insure proper operation.

Ember Installation
A bag of embers is provided to further enhance the firebox. Place the embers on the firebox floor and on
the burner. Do not place embers over any of the burner holes or air channels.
Rock Wool Placement
The included rock wool is placed on top of the burner to enhance the glow from the burner. The rock
wool works best when it is applied in a very thin layer. The best method for applying the rock wool is
to brush it on to the burner. Compress a clump of rockwool between your thumb and forefinger. Use a stiff
brush to apply a thin layer of rockwool fibers onto the burner. Do not use the entire bag of rockwool. Use
only a small amount and save the remainder. Over-use of rockwool will diminish the glow and may cause
sooting or other adverse conditions.

Maintenance 19

Yearly Service Procedure
WARNING: Failure to inspect and maintain the stove may lead to improper combustion and a potentially
dangerous situation. We recommend the following procedures be done by a qualified
technician.
 Shut off gas to the fireplace and let it cool for 15 minutes. Remove the glass. Inspect and operate the
pressure relief mechanism to verify relief mechanisms are free from obstruction to operate.
 Clean glass window with a suitable fireplace glass cleaner. Abrasive cleaners must not be used. Be
careful not to scratch the glass when cleaning.
 Vacuum and clean any debris in the firebox.
 Check all accessible gas-carrying tubes, connections, pipes and other components for leaks.
 Inspect the burner and firebox. Make sure the burner is not warped, cracked, or damaged. Check the
firebox and area around the pilot to make sure there is no damage. Inspect primary air openings for
blockage. If any problem is found, discontinue use and contact your dealer for service.
 Inspect the area behind the access door; clean if necessary. Check the gas control valve and the gas
lines. If damage is found, discontinue use and contact your dealer for service. Clean the air channels,
ducts, and blower (if applicable)
 Inspect vent and vent termination for sooting, obstructions, or damage. Make repairs as needed.
Remove any debris or vegetation near the vent termination. Contact your dealer if any sooting or
deterioration is found near the vent termination.
 Reinstall the glass assembly. If the glass is damaged, replace. Make sure the gasket along the
perimeter of the glass contacts the face of the firebox and forms an air-tight seal. If it does not, re-align or
replace the gasket to insure an air-tight seal.
 Turn the pilot flame on (continuous pilot). It should touch approximately 3/8" of the top of the flame
sensor (see below). If it does not, contact your dealer.
 Start the main burner. Inspect and ensure the lighting of the main burner occurs within 4 seconds of the
main gas valve opening.
 Test the flame failure response time of the flame safety system. It must de-energize the safety shutoff in
no more than 30 seconds.
 After 15 minutes the flames should be orange/yellow and not touch the top of the firebox. If the pilot or
main burners do not burn correctly, contact your dealer for service. Monitor blower operation
