AIR FOR COMBUSTION
AND VENTILATION
Todayʼs homes are built more energy efficient than
ever. New materials, increased insulation, and
new construction methods help reduce heat loss
in homes. Home owners weather strip and caulk
around windows and doors to keep the cold air out
and the warm air in. During heating months, home
owners want their homes as airtight as possible.
While it is good to make your home energy efficient, your home needs to breathe. Fresh air must
enter your home. All fuel-burning appliances need
fresh air for proper combustion and ventilation.
Exhaust fans, fireplaces, clothes dryers, and fuel
burning appliances draw air from the house to
operate. You must provide adequate fresh air for
these appliances. This will insure proper venting
of vented fuel-burning appliances.
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from National Fuel
Gas Code, ANSI Z223.1/NFPA 54 Section 5.3, Air
for Combustion and Ventilation.
All spaces in homes fall into one of the three following ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 5 through 7 will help
you classify your space and provide adequate
ventilation.
www.desatech.com

AIR FOR COMBUSTION
AND VENTILATION
Continued
Unusually Tight Construction
The air that leaks around doors and windows
may provide enough fresh air for combustion and
ventilation. However, in buildings of unusually
tight construction, you must provide additional
fresh air.
Unusually tight construction is defined as
construction where:
a. walls and ceilings exposed to the outside atmosphere have a continuous
water vapor retarder with a rating of
one perm (6 x 10-11 kg per pa-sec-m2) or
less with openings gasketed or sealed
and
b. weather stripping has been added on
openable windows and doors and
c. caulking or sealants are applied to
areas such as joints around window
and door frames, between sole plates
and floors, between wall-ceiling joints,
between wall panels, at penetrations
for plumbing, electrical, and gas lines,
and at other openings.
If your home meets all of the three criteria
above, you must provide additional fresh
air. See Ventilation Air From Outdoors,
page 7.
If your home does not meet all of the three
criteria above, proceed to Determining
Fresh-Air Flow For Fireplace Location,
below.
Confined and Unconfined Space
The National Fuel Gas Code, ANSI Z223.1 defines
a confined space as a space whose volume is less
than 50 cubic feet per 1,000 Btu per hour (4.8 m3
per kw) of the aggregate input rating of all appliances installed in that space and an unconfining
space as a space whose volume is not less than
50 cubic feet per 1,000 Btu per hour (4.8 m3 per
kw) of the aggregate input rating of all appliances
installed in that space. Rooms communicating
directly with the space in which the appliances
are installed*, through openings not furnished
with doors, are considered a part of the unconfined space.
* Adjoining rooms are communicating only if
there are doorless

DETERMINING FRESH-AIR FLOW
FOR FIREPLACE LOCATION
Determining if You Have a Confined or
Unconfined Space
Use this work sheet to determine if you have a
confined or unconfined space.
Space: Includes the room in which you will
install heater plus any adjoining rooms with doorless passageways or ventilation grills between
the rooms.
1.

4.
Determine the volume of the space (length x
width x height).
Length x Width x Height =__________cu. ft.
(volume of space)
Example: Space size 20 ft. (length) x 16 ft.
(width) x 8 ft. (ceiling height) = 2560 cu. ft.
(volume of space)
If additional ventilation to adjoining room is
supplied with grills or openings, add the volume
of these rooms to the total volume of the space.
Multiply the space volume by 20 to determine
the maximum Btu/Hr the space can support.
__________ (volume of space) x 20 = (Maximum Btu/Hr the space can support)
Example: 2560 cu. ft. (volume of space) x 20 =
51,200 (maximum Btu/Hr the space can support)
Add the Btu/Hr of all fuel burning appliances in
the space.

___________ Btu/Hr
Gas water heater*
___________ Btu/Hr
Gas furnace
___________ Btu/Hr
Vented gas heater

AIR FOR COMBUSTION
AND VENTILATION
12"
Continued
The space in the above example is a confined space
because the actual Btu/Hr used is more than the maximum Btu/Hr the space can support. You must provide
additional fresh air. Your options are as follows:
A. Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconfined
space, remove door to adjoining room or add
ventilation grills between rooms. See Ventilation
Air From Inside Building.
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors.
C. Install a lower Btu/Hr fireplace, if lower Btu/Hr
size makes room unconfined.
If the actual Btu/Hr used is less than the maximum
Btu/Hr the space can support, the space is an unconfined space. You will need no additional fresh
air ventilation.
WARNING: If the area in
which the heater may be operated is smaller than that defined
as an unconfined space or if the
building is of unusually tight
construction, provide adequate
combustion and ventilation air
by one of the methods described
in the National Fuel Gas Code,
ANSI Z223.1/NFPA 54 Section 5.3
or applicable local codes.

CONNECTING TO GAS SUPPLY
WARNING: This appliance
requires a 1/2" NPT (National
Pipe Thread) inlet connection
to the pressure regulator.
WARNING: A qualified service person must connect heater
to gas supply. Follow all local
codes.
CAUTION: Never connect propane/LP fireplace directly to the
propane/LP supply. This fireplace
requires an external regulator
(not supplied). Install the external
regulator between the fireplace
and propane/LP supply.
WARNING: Never connect
natural gas fireplace to private
(non-utility) gas wells. This
gas is commonly known as
wellhead gas.
Installation Items Needed
Before installing fireplace, make sure you have
the items listed below.
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• ground joint union
• sediment trap
• tee joint
• pipe wrench
• test gauge connection *
* A CSA design-certified equipment shutoff valve
with 1/8" NPT tap is an acceptable alternative to
test gauge connection. Purchase the optional CSA
design-certified equipment shutoff valve from your
dealer. See Accessories, page 32.
For propane/LP units, the installer must supply
an external regulator. The external regulator will
reduce incoming gas pressure. You must reduce
incoming gas pressure to between 11 and 14 inches
of water. If you do not reduce incoming gas pressure, heater regulator damage could occur. Install
external regulator with the vent pointing down
as shown in Figure 20. Pointing the vent down
protects it from freezing rain or sleet.
CAUTION: Use only new,
black iron or steel pipe. Internally-tinned copper tubing
may be used in certain areas.
Check your local codes. Use
pipe of 1/2" diameter or greater
to allow proper gas volume to
heater. If pipe is too small, undue
loss of volume will occur.

INSTALLATION
Continued
Installation must include an equipment shutoff
valve, union, and plugged 1/8" NPT tap. Locate
NPT tap within reach for test gauge hook up. NPT
tap must be upstream from heater (see Figure 21).
IMPORTANT: Install equipment shutoff valve
in an accessible location. The equipment shutoff
valve is for turning on or shutting off the gas to
the appliance.
Check your building codes for any special requirements for locating equipment shutoff valve
to fireplaces.
Apply pipe joint sealant lightly to male NPT
threads. This will prevent excess sealant from
going into pipe. Excess sealant in pipe could result
in clogged heater valves.
WARNING: Use pipe joint
sealant that is resistant to liquid
petroleum (LP) gas.
Installation Items Needed
• Phillips screwdriver
• sealant (resistant to propane/LP gas, not provided)
1. Route flexible gas line (provided by installer)
from equipment shutoff valve into fireplace
through side or rear access holes in outer
casing (see Figure 22).
NOTICE: Most building codes
do not permit concealed gas
connections. A flexible gas line
is provided to allow accessibility
from the fireplace (see Figure 23).
The flexible gas supply line connection to the equipment shutoff
valve should be accessible.
2. Apply pipe joint sealant lightly to male threads
of gas connector attached to flexible gas line
(see Figure 23). Connect flexible gas line
to flexible gas line attached to gas valve of
fireplace (see Figure 23).
We recommend that you install a sediment trap in
supply line as shown in Figure 21. Locate sediment
trap where it is within reach for cleaning. Install
Outer
in piping system between fuel supply and heater.
Casing
Locate sediment trap where trapped matter is not
likely to freeze. A sediment trap traps moisture and
contaminants. This keeps them from going into
heater controls. If sediment trap is not installed or
is installed wrong, heater may not run properly.

CLEANING AND
MAINTENANCE
BURNER INJECTOR HOLDER AND
PILOT AIR INLET HOLE
The primary air inlet holes allow the proper
amount of air to mix with the gas. This provides
a clean burning flame. Keep these holes clear of
dust, dirt, lint, and pet hair. Clean these air inlet
holes prior to each heating season. Blocked air
holes will create soot. We recommend that you
clean the unit every three months during operation
and have heater inspected yearly by a qualified
service person.
We also recommend that you keep the burner
tube and pilot assembly clean and free of dust and
dirt. To clean these parts we recommend using
compressed air no greater than 30 PSI. Your local
computer store, hardware store, or home center
may carry compressed air in a can. You can use a
vacuum cleaner in the blow position. If using compressed air in a can, please follow the directions on
the can. If you donʼt follow directions on the can,
you could damage the pilot assembly.

VENT-FREE GAS BAY FRONT FIREPLACE
DESA International warrants this product to be free from defects in materials and components for two (2) years
from the date of first purchase, provided that the product has been properly installed, operated and maintained
in accordance with all applicable instructions. To make a claim under this warranty the Bill of Sale or cancelled

restore this fireplace to proper operating condition and an allowance for labor when provided by a DESA Authorized Service Center. Warranty part(s) MUST be obtained through authorized dealers of this product and/or DESA
International who will provide original factory replacement parts. Failure to use original factory replacement parts
voids this warranty. The fireplace MUST be installed by a qualified installer in accordance with all local codes
and instructions furnished with the unit.
This warranty does not apply to parts that are not in original condition because of normal wear and tear, or parts
that fail or become damaged as a result of misuse, accidents, lack of proper maintenance or defects caused by
improper installation. Travel, diagnostic cost, labor, transportation and any and all such other costs related to
repairing a defective fireplace will be the responsibility of the owner.
TO THE FULL EXTENT ALLOWED BY THE LAW OF THE JURISDICTION THAT GOVERNS THE SALE
OF THE PRODUCT; THIS EXPRESS WARRANTY EXCLUDES ANY AND ALL OTHER EXPRESSED
WARRANTIES AND LIMITS THE DURATION OF ANY AND ALL IMPLIED WARRANTIES, INCLUDING
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE TO TWO (2)
YEARS ON ALL COMPONENTS FROM THE DATE OF FIRST PURCHASE; AND DESA INTERNATIONALʼS

INCIDENTAL OR CONSEQUENTIAL DAMAGES.

incidental or consequential damages, so the above limitation on implied warranties, or exclusion or limitation on
damages may not apply to you.
