Fireplace Safety
This manual contains very important information about the safe installation and operation of the fireplace. Read and
understand all instructions carefully before installing and operating the fireplace. Failure to follow these instructions
may result in possible fire hazard and will void the warranty.
Replacement manuals are available by contacting the Valor Customer Service at 1-800-468-2567, or by visiting
valorfireplaces.com.
WARNING: Extremely Hot!
Heat and flammability
• Some parts of the fireplace are extremely hot, particu-
larly the glass window. Use the barrier screen provid-
ed or a gate to reduce the risk of severe burns.
• The glass windows can exceed 500°F at full capacity.
• Always keep the appliance clear and free from com-
bustible materials, gasoline, and other flammable
vapors and liquids.
• Be aware of hot wall surfaces! The wall directly above
the fireplace can get very hot when the fireplace
heats. Although safe, it may reach temperatures in ex-
cess of 200ºF (93°C) depending on choice of optional
accessories. Do not touch!
• Be aware of hot hearth/floor surfaces! Any projections
directly around the fireplace can get very hot when
the fireplace heats. Although safe, they may reach
temperatures in excess of 200ºF (93°C) depending on
elevation of hearth. Be careful of touching these! Do
not put objects on the hearth or shelf. Temperature
of projection surfaces will be reduced when barrier
screens are installed.
• Some materials or items, although safe, may discolor,
shrink, warp, crack, peel, and so on because of the
heat produced by the fireplace. Avoid placing candles,
paintings, photos and other combustible objects
sensitive to heat or furniture within 36 inches (0.9m)
around the fireplace.
• Solid wood flooring in front of the fireplace (if allowed)
may shrink during the heating season due to heat.
• Due to high temperatures, the appliance should be
located out of traffic areas and away from furniture
and draperies.
• Clothing or other flammable material should not be
placed on or near the appliance.
Barrier Screen and Safety
• Children and adults should be alerted to the hazards
of high surface temperature and should stay away to
avoid burns or clothing ignition.
• A barrier designed to reduce the risk of burns from
the hot viewing glass is provided with this appliance
and must be installed for the protection of children
and other at-risk individuals.
• 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 recom-
mended if there are at-risk individuals in the house. To
restrict access to a fireplace or stove, install an adjust-
able safety gate to keep toddlers, young children, and
other at-risk individuals out of the room and away
from hot surfaces.
• Any safety screen, guard, or barrier removed for ser-
vicing an appliance, must be replaced prior to operat-
ing the appliance.

Fireplace Safety
Glass window
• The glass front assembly must be in place and sealed
before the unit can be placed into safe operation.
• The glass front assembly must only be replaced as a
complete unit, as supplied by the fireplace manufac-
turer. No substitute material may be used.
• Do not strike or slam the glass front.
• Do not use abrasive cleaners on the glass front as-
sembly. Do not attempt to clean the glass when it is
hot.
Venting
• This unit must be used with a vent system as de-
scribed in this manual. No other vent system or com-
ponents may be used.
• Never obstruct the flow of combustion and ventilation
air. Keep the front of the appliance clear of all obsta-
cles and materials for servicing and proper operation.
• This gas fireplace and vent assembly must be vented
directly to the outside and must never be attached to
a chimney serving a separate solid fuel burning ap-
pliance. Each gas appliance must use a separate vent
system. Common vent systems are prohibited.
WARNING
Do not operate appliance with the glass
front removed, cracked, or broken.
Replacement of the glass should be done
by a licensed or qualified service person.
Intended use
• This appliance is designed and approved as a supple-
mental heater and provides the potential for most
energy conservation when used while attended. The
use of an alternate primary heat source is advisable.
• This unit is not for use with solid fuel.
• Do not use this heater as a temporary source of heat
during construction.
Installation and Servicing
• The appliance and its venting system should be
inspected before use and at least once a year by
a qualified service person.
• 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 com-
partments, burners, and circulating air passageways
of the appliance be kept clean.
• 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 that has been
under water.
