4Safety Precautions
© Travis Industries 4121129 100-01314
•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 preventthe 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 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 use this appliance if any
part has been under water.
Immediately call a qualified
service technician to inspect
the appliance and to replace
any part of the control system
and any gas control which has
been under water.

Safety Precautions 5
© Travis Industries 4121129 100-01314
•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 lighting the
pilot or conducting service.
•Any safety screen or guard
removed for servicing must be
replaced prior to operating the
heater.
•Do not operate with the glass
removed or damaged.
•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 included
fiber logs).
•If the fiber logs become
damaged, replace with Travis
Industries log set.
•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.
•Plug the heater into a 120V
grounded electrical outlet. Do
not remove the grounding plug.
•Don’t route the electrical cord in
front of, over, or under the
heater
•TravisIndustries, Inc. grants
no warranty, implied or
stated, for the installation or
maintenance of your heater,
and assumes no
responsibility of any
consequential damage(s).
Young children should be
carefully supervised when they
are in the same room as the
appliance. Toddlers, young
children and others may be
susceptible to accidental contact
burns. A physical barrier is
recommended if there are at risk
individuals in the house. To
restrict access to a fireplace or
stove, install an adjustable safety
gate to keep toddlers, young
children and other at risk
individuals out of the room and
away from hot surfaces.

Installation Hints
If converting to LP, convert the appliance prior to installation.
Install the logs last - they are fragile.
When determining the location of the stove, locate the wall studs (for horizontal penetrations) and
ceiling trusses (for vertical penetrations). You may wish to adjust the stove position slightly to ensure
the vent does not intersect with a framing member.
Fumes and smoke from the paint curing and oil burning off the steel may occur the first time you start
this heater. This is normal. We recommend you open windows to vent the room.

Vent Requirements
•The gas appliance and vent system must be vented directly to the outside of the building, and never
be attached to a chimney serving a separate solid fuel or gas-burning appliance. Each direct vent
gas appliance must use its own separate vent system.
In addition to the requirements listed here, follow the requirements provided with the vent.
When the vent passes through a wall a wall thimble is required. When the vent passes through a
ceiling a support box or firestop is required. When the vent passes through the roof, a roof flashing
and storm collar are required. Follow the instructions provided with the vent for installing these items.
NOTE: Wall thimbles may have different dimensions than what is required by this heater.
•The vent must maintain the required 1" (26mm) clearance to combustible materials to prevent a fire.
Do not fill air spaces with insulation.
Altitude Considerations
•Failure to adjust the air shutter
properly may lead to improper
combustion which can create a
safety hazard. Consult your dealer
or installer if you suspect an
improperly adjusted air shutter.
•This heater has been tested at
altitudes ranging from sea level to
6,000 feet (1,800 M). In this
testing we have found that the
heater, with its standard orifice,
burns correctly with just an air
shutter adjustment.
Approved Vent
Use 6-5/8" (168mm) diameter Simpson Dura-Vent Direct-Vent Pro (or GS)*.
* Other vent may be approved with this stove. Check with the vent manufacturer for details.
Always use the high-wind cap (or high-wind sconce cap, part # 46DVA-HSCH).
Installation instructions for Simpson Dura-Vent may be found at www.duravent.com
Vent Installation
•Slide the vent sections together and turn 1/4 turn until the sections lock in place.
•Screws are not required to secure the vent. However, three screws may be used to
secure vent sections together if desired.
•High temperature sealant is recommended at the appliance starter section connection
(use high-temperature silicone or Mill-Pac®).
•If disassembly is required, at time of re-assembly check to see if the vent creates a tight
fit. If it does not, apply high temperature sealant to the joints of the affected sections.
•Horizontal sections require a 1/4" (7mm) rise every 12" (305mm) of travel
•Horizontal sections require non-combustible support every three feet (e.g.: plumbing tape)
