6 Safety Precautions
© Travis Industries 4/19/23 - 1453 PB 42 & 54 MV/GSB2/GSR2 Install
Safety Warnings
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 of 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 under water.

Safety Precautions 7
© Travis Industries 4/19/23 - 1453 PB 42 & 54 MV/GSB2/GSR2 Install
Safety Warnings (continued)
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 the appliance.
Light the heater using the built-in igniter. Do not use matches or any other external device to light your
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.

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 maintenance
of your heater, and assumes no responsibility of any consequential damage(s).

Televisions Placed Above the Fireplace
The following section gives guidelines to place a television above the fireplace.
IMPORTANT NOTE REGARDING TELEVISIONS AND THIS FIREPLACE
Most television manufacturers instruct the homeowner not to place the television above a heat source like this fireplace. Doing
so may decrease the longevity of the television and negate the warranty. If you do place a television above the fireplace, you
should place a mantel (or build-out) between the fireplace and television (or use a CoolSmart TV Wall™ kit). Follow the
guidelines below to reduce the amount of heat reaching the television. Travis Industries does not take responsibility for any
negative impact to televisions placed near this fireplace.
Minimum Dimensions:
(a) Minimum Mantel Height above Base of Fireplace* 39” (991mm) with 4” (102mm) mantel depth
(b) Minimum Mantel Depth* 4” (102mm)*
(c) Optional Columns (or Build-Out) Must Meet Side Wall Clearances
(Measured to the side of fireplace ZC-can)
* Minimum mantel depth must be 4”(102mm) to allow heat to dissipate. If using a mantel larger than 4”(102mm),
make sure to adjust the mantel height (a) to meet the mantel clearance (see mantel requirements on page 49 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 2” 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. Any build-out near the television must
maintain a 3” gap to the top and sides to prevent heat from being trapped near the television.
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.

Header and Pipe Shield Installation
