AIR FOR COMBUSTION AND VENTILATION

Continued

If your home meets all of the three criteria 

above, you must provide additional fresh 

air. See 

Ventilation Air From Outdoors

page 8.

If your home does not meet all of the 

three criteria above, proceed to Determin-

ing 

Fresh-Air Flow For Heater Location

below.

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/hr (4.8 m

3

 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/hr (4.8 m

3

 per kw) of the ag-

gregate 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 un

-

confined space.

* Adjoining rooms are communicating only if 

there are doorless passageways or ventilation 

grills between them.

DETERMINING FRESH-AIR FLOW 

FOR HEATER 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 

fireplace  plus  any  adjoining  rooms  with  door

-

less 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 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. 

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:

 2560 cu. ft. (volume of space) x 20 

= 51,200 (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. 

Direct-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.

 

 _______ Btu/Hr (maximum can support) 

 

 _______ Btu/Hr (actual amount used)

 

Example:

  51,200  Btu/Hr  (maximum  the 

space can support) 

 

 

73,000 Btu/Hr (actual amount of 

Btu/Hr used)

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 sup-

port. 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 adjoin

-

ing room or add ventilation grills between 

rooms. See 

Ventilation Air From Inside 

Building, 

page 8

.

B.  Vent room directly to the outdoors. See 

Ventilation Air From Outdoors, 

page 8.

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.
