4 Safety Precautions
© Travis Industries 11/9/20 - 1478 PB 72 GSB2/GSR2 Aust.
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.

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 clearancer (see mantel
requirements on page Error! Bookmark not defined. 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. 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.
NOTE: The mantel must extend 1”(26mm) in front of the TV and 1”(26mm) to both sides. If you have a TV that is
greater than 3” (77mm) deep (including the 1”(26mm) gap behind), you will need to alter the mantel depth and height.
