Confined and Unconfined Space

The National Fuel Gas Code ANS Z223.1

defines a confined space as a space whose

volume is less than 50 cubic feet per 1,000

Btu per hour (4.8 m3 per kw) of the aggre-

gate input rating of all appliances installed

in that space and an unconfined space as a

space whose volume is not less than 50

cubicfeetper1,000Btuperhour(4.8m3per

kw) of the aggregate input rating of all

appliances installed in that space. Rooms

communicating directly with the space in

whichtheappliancesareinstalled*,through

openings not furnished with doors, are con-

sidered a part of the unconfined space.

This heater shall not be installed in a con-

fined space or unusually tight construction

unlessprovisions are providedfor adequate

combustion and ventilation air.

tion grills between them.

AIR FOR

COMBUSTION AND

VENTILATION

Today’s homes are built more energy effi-

cient than ever. New materials, increased

insulation, and new construction methods

helpreduceheatlossinhomes.Homeowners

weatherstrip and caulkaround windows and

doorstokeepthecoldairoutandthewarmair

in. During heating months, home owners

want their homes as airtight as possible.

While it is good to make your home energy

efficient,yourhome needstobreathe. Fresh

air must enter your home. All fuel-burning

appliances need fresh air for proper com-

bustion and ventilation.

Exhaustfans,fireplaces,clothesdryers,and

fuel burning appliances draw air from the

house to operate. You must provide ad-

equate 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. NFPA 54/ANS Z223.1, Sec-

tion5.3,AirforCombustionandVentilation.

Allspacesinhomesfallintooneofthethree

following ventilation classifications:

1. Unusually Tight Construction

2. Unconfined Space

3. Confined Space

The information on pages 4 through 6 will

help you classify your space and provide

adequate ventilation.

Unusually Tight Construction

The air that leaks around doors and win-

dows 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 de-

fined as construction where:

a. walls and ceilings exposed to the

outside atmosphere have a con-

tinuous water vapor retarder with

a rating of one perm (6x10-11 kg

per pa-sec-m2) or less with open-

ings 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, be-

tween sole plates and floors,be-

tween wall-ceiling joints, be-

tween wall panels, at penetra-

tionsforplumbing,electrical,and

gas lines, and at other openings.

If your home meets all of the three

criteria above, you must provide ad-

ditional fresh air. See

Ventilation Air

From Outdoors

, page 6

If your home does not meet all of the

three criteria above, proceed to

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:Includestheroominwhichyouwillinstallheaterplusanyadjoiningroomswithdoorlesspassagewaysorventilationgrillsbetween

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.

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.

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)

ThespaceintheaboveexampleisaconfinedspacebecausetheactualBtu/HrusedismorethanthemaximumBtu/Hrthespacecansupport.

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 6.

B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 6.

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.

WARNING:Iftheareainwhichtheheatermaybeoperatedissmallerthanthatdefinedasanunconfinedspace

or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of

the methods described in the
