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 unconfined space.

Space:

 Includes the room in which you will 

install  appliance  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 sup-

port.

 

 ________ (volume of space) x 20 = (Maxi-

mum 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.

 

Gas water appliance*   __________ Btu/Hr

 

Gas furnace 

 __________ Btu/Hr

 

Vented gas appliance   __________ 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 appliance   __________ Btu/Hr

 

Gas firebox logs 

+ _________ Btu/Hr

 Total 

= _________ Btu/Hr

AIR FOR COMBUSTION AND VENTILATION

Continued

  40,000
  39,000
  79,000

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)

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  work  sheet,  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

, page 8.

B.  Vent room directly to the outdoors. See 

Ventilation Air from Outdoors

, page 8.

C.  Install a lower Btu/Hr gas log appliance, 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 appliance may be operated 

does not meet the required vol-

ume for indoor combustion air, 

combustion and ventilation air 

shall be provided by one of 

the methods described in the 

National Fuel Gas Code, ANSI 

Z223.1/NFPA 54, 

the

 Internation-

al Fuel Gas Code,

 or applicable 

local codes.
