AIR FOR COMBUSTION AND VENTILATION  

Confined and Unconfined Space

The National Fuel Gas Code, ANSI Z223.1/NFPA 54 defines a confined 

space as a space whose volume is less than 50 cubic feet per 1,000 

Btu per hour (4.8 m

3

 per kw) of the aggregate input rating of all ap-

pliances 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 m

3

 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.

DETERMINING FRESH-AIR FLOW FOR FIREBOX LOCATION
Determining if You Have a Confined or Unconfined Space

Use this work sheet to determine if you have a confined or uncon-

fined 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.  Determine the volume of the space (length x width x height).
  Length x Width x Height = __ cu. ft. (volume of space)
  Example: Space size 22 ft. (length) x 18 ft. (width) x 8 ft. (ceiling 

height) = 3168 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 = (Maximum Btu/Hr the space can 

support)

  Example: 3168 cu. ft. (volume of space) x 20 = 63,360 (maximum 

Btu/Hr the space can support)

3.  Add the Btu/Hr of all fuel burning appliances in the space.
  Vent-free heater 

 ______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. Direct-vent draws 

combustion air from the outdoors and vents to the outdoors.

  Example:
  Gas water heater     40,000 Btu/Hr
  Vent-free heater  + 39,000 Btu/Hr
 Total 

79,000 Btu/Hr

4.  Compare the maximum Btu/Hr the space can support with the 

actual amount of Btu/Hr used.

   ________ Btu/Hr (maximum the space can support) 
   ________ Btu/Hr (actual amount of 
   

Btu/Hr used)

  Example:  63,360 Btu/Hr (maximum the space can support) 

   

  79,000 Btu/Hr (actual amount of Btu/Hr used)

 WARNING: This heater shall not be installed in a 

room or space unless the required volume of indoor 

combustion air is provided by the method described 

in the National Fuel Gas Code, ANSI Z223.1/NFPA 54, 

the International Fuel Gas Code, or applicable local 

codes. 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 energy efficient than ever. New materi-

als, 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, fireboxes, 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, 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 page 8 through 10 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.

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-m

2

) 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, be-

tween 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 9. 
If your home does not meet all of the three criteria above, proceed 

to Determining Fresh-Air Flow for Firebox Location.
