4 Safety Precautions
© Travis Industries 5/20/2021 - 1558 430 MF GSR2
 Failure to follow all of the requirements may result in property damage, bodily injury, or even death.
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.
Children and adults should be alerted to the hazards of high surface temperature
and should stay away to avoid burns or clothing ignition. Do not touch the hot
surfaces of the heater. Educate all children about the danger of a high-
temperature heater.
Due to the high temperature, the heater should be located out of traffic and away
from furniture and draperies.
 This unit must be installed by a qualified installer
to prevent the possibility of an explosion.
 This appliance must be installed in accordance
with all local codes if any; if not, in U.S.A. follow
ANSI Z223.1 and NFPA 54(88), in Canada follow
CSA B149.1.
 A manufactured home (USA only) or mobile
home OEM installation must conform with the
Manufactured Home Construction and Safety
Standard, Title 24 CFR, Part 3280, or, when
such a standard is not applicable, the Standard
for Manufactured Home Installations,
ANSI/NCSBCS A225.1, or Standard for Gas
Equipped Recreational Vehicles and Mobile
Housing, CSA Z240.4. This appliance may be
installed in Manufactured Housing only after the
home is site located.
 All exhaust gases must be vented outside the
structure of the living area. Combustion air is
drawn from outside the living-area structure. The
venting must not be connected to a chimney flue
serving a separate solid-fuel burning appliance.
 Notify your insurance company before hooking
up this fireplace.
 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 approved for use with natural gas
(NG) or 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.
 Contact your local building officials to obtain a
permit and information on any installation
restrictions or inspection requirements in your
area.
 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 which
has been underwater.

Safety Precautions 5

person.
 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.
 Instruct everyone in the house how to shut the
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.
 A barrier designed to reduce the risk of burns
from the hot viewing glass is provided with this
appliance and shall be installed for the
protection of children and other at-risk
individuals.
 If the barrier becomes damaged, the barrier
shall be replaced with the manufacturer’s
barrier for this appliance.
 Clothing or other flammable material should not
be placed on or near the appliance.
 Any safety screen, guard, or barrier removed
for servicing an appliance must be replaced
prior to operating the appliance.
 Installation and repair should be done by a
qualified service person. The appliance should
be inspected before use and at least annually
by a professional service person. More
frequent cleaning might be required due to
excessive lint from carpeting, bedding material,
et cetera. It is imperative that control
compartments, burners, and circulating air
passageways of the appliance be kept clean.
 Travis Industries, Inc. grants no warranty,
implied or stated, for the installation or

Televisions Placed Above the Insert
The following section gives guidelines to place a television above the insert.
IMPORTANT NOTE REGARDING TELEVISIONS AND THIS INSERT
Most television manufacturers instruct the homeowner not to place the television above a heat source like this insert.
Doing so may decrease the longevity of the television and negate the warranty. If you do place a television above the
insert, you should place a mantel between the insert and television. Follow the guidelines below to reduce the
amount of heat reaching the television. Travis Industries does not take responsibility for any negative impact on
televisions placed near this insert.
Minimum Dimensions:
(a) Minimum Mantel Height above Base of Insert* 34” (864mm) with 8” (204mm) mantel depth
(b) Minimum Mantel Depth* 8” (204mm)*
* Minimum mantel depth must be 8”(204mm) to allow heat to dissipate. If using a mantel larger than 8”
(204mm), make sure to adjust the mantel height (a) to meet the mantel clearance (see mantel requirements
on page 10 for details).
 The mantel must extend 2” in front of the television and 1” to both sides.
 If you have a television that is greater than 6” deep (including the 1” gap behind), you will need to alter the
mantel depth and height (see the example below).
 The television must have a 1” gap to the wall to allow for proper cooling.
WIRING NOTE: If running wiring into the enclosure, use thermal insulating wrap around the wiring. Secure the wiring
to protect from contact with hot surfaces.

 The supply regulator (the regulator that attaches directly to the residence inlet or to the propane tank)
should supply gas at the suggested input pressure listed above. Contact the local gas supplier if the
regulator is at an improper pressure.

Vent Requirements
Travis Industries manufactures a vent kit specifically for this insert (sku 96200339).
It includes 30’ (10M) of vent, hose clamps, and a high wind cap. The flashing on
the cap is 18” (458mm) by 18” (458mm).
Travis Industries manufactures a vent kit specifically for this insert (sku 96200330).
It includes 30’ (10M) of vent, hose clamps, and a prairie cap. The flashing on the
cap is 18” (458mm) by 18” (458mm).
 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.
 Make sure the exhaust pipe on the heater connects to the exhaust portion of the cap. The illustrations below show
how the flex liners should be attached.
 The exhaust vent must reline the entire length of the chimney and terminate above the chimney top.
 Be careful not to crimp or rupture the liner when bending it into chimney offsets.
 When installed, the vent must meet all of the vent manufacturer's requirements.
 Use the following vent:
3” UL 441 or 1777 Gas Liner for Exhaust, 3” UL 441 or 1777 Gas Liner for Air Inlet
Duravent 6-5/8” to 3” Co-Linear Adapter and Flashing (46DVA-Gk)
Duravent High-Wind Vertical Termination (46DVA-VCH) for high-wind applications or Prairie Cap
Drafting Performance
This direct vent appliance requires natural draft to operate (similar to a wood stove or other heating appliance). Draft
can be adjusted using the included restrictor. The restrictor settings detailed in the manual should be followed
(variations may occur depending upon installation parameters).
Many factors may negatively influence the draft of the appliance. Travis Industries will not be responsible for improper
draft due to factors such as trees, hills, buildings, obstructions, excessive wind, extreme hot or cold outdoor
temperatures, restrictive vent terminations, or influence from mechanical systems.

Vent Location
 An Exhaust Restrictor is built into the appliance to adjust the flow rate of exhaust gases. This
ensures proper combustion for all vent configurations. Depending upon the vent configuration, you
may be required to adjust the restrictor position. See “Exhaust Restrictor Settings” on page 21.
Vent Configurations
Altitude Considerations
 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.
 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.

Vent Attachment – Tight Installations
The vent connector is shipped attached to the insert but must be removed to facilitate tight
installations. See the directions below for installation.
1. Locate the screw in the top-center of the front of the insert. Use a ¼” nut driver to remove the screw
and slide the connector toward the back of the insert to disengage the connector from the top of the
insert.
2. Stretch the liners to their full length. Attach the flex liners to the cap (secure with screws). Route the
flex vent through the chimney from above.

3. Pull the liners straight and cut to length (height of the insert). Attach the bottom of the flex liners to the
connector, removed in step 1.
4. Slide the insert into place while guiding the vent connector into the guides on top of the insert. Secure
the vent connector to the appliance using the screw removed in step 1.
