AIR FOR COMBUSTION
AND VENTILATION
WARNING: This fireplace
shall not be installed in a con-
fined space or unusually tight
construction unless provisions
are provided for adequate com-
bustionandventilationair.Read
the following instructions to in-
sureproperfreshairforthisand
otherfuel-burningappliancesin
your home.
Today’s 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 effi-
cient, 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 fol-
lowing ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 6 through 8 will help you
classifyyour space andprovideadequateventilation.
Unusually Tight Construction
The air that leaks around doors and windows may
provide enough fresh air for combustion and ven-
tilation. However, in buildings of unusually tight
construction,you must provide additional fresh air.

www.desatech.com
113110-01A 7
Unusually tight construction is defined as
construction where:
a. walls and ceilings exposed to the out-
side 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 ar-
eas such as joints around window and
door frames, between sole plates and
floors, between wall-ceiling joints, be-
tween wall panels, at penetrations for
plumbing, electrical, and gas lines, and
at other openings.
If your home meets all of these three crite-
ria, you must provide additional fresh air.
See Ventilation Air From Outdoors , page 8 .
If your home does not meet all of the three
criteriaabove,proceedto DeterminingFresh-
Air Flow For Fireplace Location, below.
Confined and Unconfined Space
The National Fuel Gas Code,ANSI Z223.1/NFPA
54 defines a confined space as a space whose vol-
ume is less than 50 cubic feet per 1,000 Btu per
hour (4.8 m3per kw) of the aggregate input rating
of all appliances installed in that space and an un-
confined space as a space whose volume is not
less than 50 cubic feet per 1,000 Btu per hour (4.8
m3per kw) of the aggregate input rating of all ap-
pliances installed in that space. Rooms communi-
cating directly with the space in which the appli-
ances are installed*, through openings not fur-
nished with doors, are considered a part of the
unconfined space.
*Adjoiningroomsare communicating only if there
are doorless passageways or ventilation grills be-
tween them.

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 in-
stall fireplace plus any adjoining rooms with
doorlesspassageways or ventilation grills between
the rooms.
1. Determine the volume of the space (length x
width x height).
Length x Width x Height =__________cu. ft.
(volume of space)
Example: Space size 16 ft. (length) x 14 ft.
(width) x 8 ft. (ceiling height) = 1792 cu. ft. (vol-
ume of space)
If additional ventilation to adjoining room is sup-
plied with grills or openings, add the volume of
these rooms to the total volume of the space.
2. Multiply the space volume by 20 to determine
the maximum Btu/Hr the space can support.
__________ (volume of space) x 20 = (Maxi-
mum Btu/Hr the space can support)
Example: 1792 cu. ft. (volume of space) x 20 =
35,840 (maximum Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in
the space.
Vent-free fireplace _________ Btu/Hr
Gas water heater* _________ Btu/Hr
Gas furnace _________ Btu/Hr
Vented gas heater _________ Btu/Hr
Gas fireplace logs _________ Btu/Hr
Other gas appliances* + ________ Btu/Hr
Total = ________ Btu/Hr
* Do not include direct-vent gas appliances. Di-
rect-ventdrawscombustion air from the outdoors
and vents to the outdoors.
Example:
Gas water heater _____________ Btu/Hr
Vent-free fireplace _____________ Btu/Hr
Total _____________ Btu/Hr
4. Compare the maximum Btu/Hr the space can
support with the actual amount of Btu/Hr used.
________ Btu/Hr(maximumthespacecansupport)
________ Btu/Hr(actual amount of Btu/Hr used)
Example: 35,840 Btu/Hr (maximum the space
can support)
40,000 Btu/Hr (actual amount of
Btu/Hr used)
30,000
10,000
40,000

www.desatech.com 113110-01A
8
Thespace in the above exampleis aconfined 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 ad-
joining 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 Venti-
lation 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 maxi-
mum 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 fireplace may be op-
erated is smaller than that de-
finedasanunconfinedspaceor
if the building is of unusually
tight construction, provide ad-
equate combustion and ventila-
tion air by one of the methods
described in the National Fuel
Gas Code, ANSI Z223.1/NFPA
54 Section 5.3 or applicable lo-
cal codes .
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining un-
confined space. When ventilating to an adjoining
unconfined space, you must provide two perma-
nent openings: one within 12" of the ceiling and
one within 12" of the floor on the wall connecting
the two spaces (see options 1 and 2, Figure 4).
You can also remove door into adjoining room (see
option 3, Figure 4). Follow the National Fuel Gas
Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for
Combustion and Ventilation for required size of
ventilation grills or ducts.
AIR FOR COMBUSTION
AND VENTILATION
Continued
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills
or ducts. You must provide two permanent open-
ings: one within 12" of the ceiling and one within
12" of the floor. Connect these items directly to
the outdoors or spaces open to the outdoors. These
spaces include attics and crawl spaces. Follow the
National Fuel Gas Code, ANSI Z223.1/NFPA 54,
Section 5.3, Air for Combustion and Ventilation
for required size of ventilation grills or ducts.
IMPORTANT: Do not provide openings for inlet
or outlet air into attic if attic has a thermostat-con-
trolled power vent. Heated air entering the attic
will activate the power vent.

are attached to your fireplace, these spacers can be
placed directly against wall or framing materials.
Note: When installing fireplace directly on car-
peting, tile or other combustible material, other
than wood flooring, the fireplace shall be installed
on a metal or wood panel extending the full width
and depth of the fireplace.
Use the dimensions shown for rough openings to
create the easiest installation (see Built-In Fire-
place Installation, page 10).
CHECK GAS TYPE
Use the correct gas type (natural or propane/LP)
for your unit. If your gas supply is not correct, do
not install fireplace. Call dealer where you bought
fireplace for proper type fireplace.
WARNING: This appliance
is equipped for (natural or pro-
pane/LP) gas. Field conversion
is not permitted.
INSTALLATION ITEMS

BUILT-IN FIREPLACE
INSTALLATION
Built-in installation of this fireplace involves in-
stalling fireplace into a framed-in enclosure. This
makes the front of fireplace flush with wall. An
optional trim kit accessory is available (see Ac-
cessories, pages 36 and 37). Trim will extend past
sidesof fireplaceapproximately 1/2inch. This will
cover the rough edges of the wall opening. If in-
stalling a built-in mantel above the fireplace, you
must follow the clearances shown in Figure 10,
page 12. Follow the instructions below to install
the fireplace in this manner.
