AIR FOR COMBUSTION
AND VENTILATION
WARNING: This fireplace shall not be installed in a con­fined space or unusually tight construction unless provisions are provided for adequate com­bustion and ventilation air. Read the following instructions to in­sure proper fresh air for this and other fuel-burning appliances in your home.
Today’ s homes are built more ener gy 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/NFP A 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 6 through 8 will help you
classify your space and provide adequate ventilation.
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.

www.desatech.com 113110-01A
AIR FOR COMBUSTION
AND VENTILATION
Continued
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 or less with openings gasketed or sealed
and
b. weather stripping has been added on
openable windows and doors
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, be­tween wall panels, at penetrations for plumbing, electrical, and gas lines, and at other openings.
If your home meets all of these three crite­ria, you must provide additional fresh air. See
Ventilation Air From Outdoor s
If your home does not meet all of the three criteria above, proceed to
Air Flow For Fireplace Location,
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 m3 per kw) of the aggregate input rating of all appliances installed in that space and an un­confined 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 passageways or ventilation grills be­tween them.

below.
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 doorless passageways 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:
(width) x 8 ft. (ceiling height) = 1792 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.
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:
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-vent draws combustion 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.
________ ________
Example:
Space size 16 ft. (length) x 14 ft.
1792 cu. ft. (volume of space) x 20 =
30,000 10,000 40,000
Btu/Hr (maximum the space can support) Btu/Hr (actual amount of Btu/Hr used) 35,840 Btu/Hr (maximum the space
can support) 40,000 Btu/Hr (actual amount of
Btu/Hr used)

AIR FOR COMBUSTION
AND VENTILATION
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. Y ou 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. V ent 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 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 fireplace 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
Gas Code, ANSI Z223.1/NFPA 54 Section 5.3
cal codes
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining un­confined space. When ventilating to an adjoining unconfined space, you must provide two perma­nent 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). Y ou 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.
