DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION

Determining if You Have a Confined or Unconfined Space

Use this worksheet to determine if you have a confined or unconfined 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

18 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) =
2304 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. Divide the space volume by 50 cubic feet to determine the maximum BTU/Hr the space

can support.

____________ (volume of space) 

÷

 50 cu. ft. = (Maximum BTU/Hr

the space can support)

Example:

 

2304 cu. ft. (volume of space) 

÷

 50 cu. ft. =   46.1 or 46,100 (maximum

BTU/Hr the space can support)

3. Add the BTU/Hr of all fuel burning appliances in the space.

Total

=

50,000

BTU/Hr

* Do not include direct-vent gas appliances. Direct-vent draws combustion air from the
outdoors and vents to the outdoors.

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:

46,100

BTU/Hr (maximum the space can support)

50,000

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 support. 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 adjoining room or add ventilation grills between
rooms. See Ventilation Air From Inside Building, page 7.

B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 8.
C. Install a lower BTU/Hr heater, 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.
