SAFETY
INFORMATION
WARNINGS
IMPORTANT: Read this owner’s
manual carefully and completely
before trying to assemble, operate, or service this stove and burner
system. Improper use of this stove
and burner system can cause serious injury or death from burns,
fire, explosions, electrical shock,
and carbon monoxide poisoning.
DANGER: Carbon monoxide
poisoning may lead to death!
This stove with burner system is a vented
product. This stove with burner system will
not produce any gas leakage into your home if
properly installed. This stove must be properly
installed by a qualified service person. The
glass door must be properly seated and sealed.
If this unit is not properly installed by a qualified service person with glass door properly
seated and sealed, gas leakage can occur.
Carbon Monoxide Poisoning: Early signs
of carbon monoxide poisoning resemble the
flu, with headaches, dizziness, or nausea. If
you have these signs, the stove may not have
been installed properly. Get fresh air at
once! Have stove inspected and serviced by
a qualified service person. Some people are
more affected by carbon monoxide than others. These include pregnant women, people
with heart or lung disease or anemia, those
under the influence of alcohol, and those at
high altitudes.
Propane/LP gas and natural gas are both
odorless. An odor-making agent is added to
each of these gases. The odor helps you
detect a gas leak. However, the odor added
to these gases can fade. Gas may be present
even though no odor exists.
Make certain you read and understand all
warnings. Keep this manual for reference. It
is your guide to safe and proper operation of
this stove and burner system.

PRE-INSTALLATION
PREPARATION
WARNING: A qualified service person must install stove
and burner system. Follow all local codes.
Corner Installation
CAUTION: This stove creates
warm air currents. These currents
move heat to wall surfaces next
to stove. Installing stove next to
vinyl or cloth wall coverings or
operating stove where impurities
(such as tobacco smoke, aromatic candles, cleaning fluids,
oil or kerosene lamps, etc.) in the
air exist, may discolor walls.
LOCATION AND SPACE
REQUIREMENTS
Determine the safest and most efficient location for your Sun Valley B-vent freestanding
stove. Make sure that rafters and wall studs
are not in the way of the venting system.
Choose a location where the heat output is
not affected by drafts, air conditioning ducts,
windows, or doors. Figure 2 shows some
common locations. Read all venting information in this manual. Be aware of all restrictions and precautions before deciding the
exact location for your stove.
When deciding the location of your stove,
follow these rules:
1. Do not connect this stove and burner
system to a chimney flue serving a
separate solid-fuel burning fireplace or
appliance.
2. Due to high temperatures, do not locate this stove in high traffic areas or
near furniture or draperies.
3. Proper clearances must be maintained,
see Figures 3 and 4.
4. This stove is a freestanding unit designed to set directly on the floor. If
your stove is to be installed directly on
carpeting, vinyl tile, or any combustible
material other than wood, it must be
installed on a metal or wood panel extending the full width and depth of the
stove. See Figure 5.

VENTING
INSTALLATION
WARNING: Read all instructions completely and thoroughly
before attempting installation. Failure to do so could result in serious
injury, property damage, or loss of
life. Operation of improperly installed and maintained venting system could result in serious injury,
property damage, or loss of life.
NOTICE: Failure to follow these
instructions will void the warranty.
INSTALLATION PRECAUTIONS
Consult local building codes before beginning the installation. Only a qualified service person should install venting system.
The installer must follow these safety rules:
• Wear gloves and safety glasses for
protection
• Use extreme caution when using ladders
or when on roof tops
• Be aware of electrical wiring locations
in walls and ceilings
The following actions will void the warranty on your venting system:
• Installation of any damaged venting
component
• Unauthorized modification of the venting system
• Installation of any component part not
manufactured or approved by DESA
International
• Installation other than as instructed by
these instructions
Your burner system is approved for use with
any listed gas vent. A listed gas vent is a factory
made and listed system designed, and installed
exclusively for removing products of combustion, excess air, and dilution air resulting from
burning fuel gas. Metal vents, the most common type of vent, employ double wall construction enclosing an insulating air space.
This air space both helps keep flue gases warm
and reduce heat transferred to nearby combustibles. This appliance is equipped with a safety
control system designed to protect against
improper venting of combustion products.
Continued
SUN VALLEY STOVE COMPANY
CAST IRON STOVE AND BURNER SYSTEM
VENTING
INSTALLATION
Continued
It is very important that the venting system
maintain its balance between the combustion air intake and the flue gas exhaust.
Certain limitations apply to vent configurations and must be strictly followed.
WARNING: This gas stove with
burner system and vent assembly
must be vented directly to the outside. The venting system must
NEVER be attached to a chimney
serving a separate solid fuel burning appliance.
TYPE B-VENT INSTALLATION
(Listed B-0 or Greater)
Before beginning installation be sure that the
overall height and gas vent size conform to
building code requirements. Gas vents extending through pitched roofs can extend a
minimum height of at least 600 mm (2')
higher than any obstruction within 3m (10').
Gas vents extending through flat roofs are
required to extend at least 600 mm (2') above
the roof and at least 600 mm (2') higher than
any portion of the building or adjoining building within 3m (10') of the gas vent.
• Venting instruction contained in this
manual may or may not apply to your
area. Consult your local authority for requirement in your area.
• Where the gas vent extends through accessible spaces, it should be enclosed to
avoid personal contact and damage. Enclosure walls should have a fire rating
equal to or greater than the floors through
which the gas vent passes except in single
or two-family dwellings.
• Situate the gas vent in the structure so
that it can be installed without cutting
joists, sills, plates, or major load bearing
partitions or members. It is also important to locate the base of the gas vent as
near as possible to the heating appliance.
• This heater must be properly connected to
a venting system. This heater is equipped
with a vent safety shutoff system.
• Use only vents labeled "FOR EXTERIOR USE" above the roofline.
• Consult the authority having jurisdiction to select the correct gas vent diameter. Avoid using a larger than necessary diameter.

WARNING: Installation should
only be made by qualified persons who are familiar with the
safety procedures required for
the installation of the product,
who are equipped with the proper
tools and testing instruments,
and who have achieved proper
certification of licensing. Installations made by unqualified persons can result in the risk of injury or electrical shock which can
be serious or even fatal.
Figure 24 and Figures 25 and 26, page 11,
show other options for the gas vent. When
venting through a side wall your vent pipe
must have the proper temperature rating
(see Figure 26, page 11). Manufacturer’s
clearances must also be maintained. Consult the authority having jurisdiction in your
area regarding venting through side wall.
