AIR FOR COMBUSTION AND

VENTILATION

Today’s homes are built more energy efficient than ever. New

materials, 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.Duringheatingmonths,homeownerswanttheirhomesasairtight

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.

Exhaustfans,fireplaces,clothesdryers,andfuelburningappliances

drawairfromthehousetooperate.Youmustprovideadequatefresh

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, Section 5.3, 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 pages 4 through 6 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.

WARNING: This heater shall not be installed in a

confined space or unusually tight construction un-

lessprovisionsareprovidedforadequatecombustion

and ventilation air. Read the following instructions to

insure proper fresh air for this and other fuel-burning

appliances in your home.

Unusually tight construction is defined as construction

where:

a. walls and ceilings exposedtotheoutsideatmosphere

have a continuous water vapor retarder with a rating

of one perm (6x10-11 kg per pa-sec-m2) or less with

openings gasketed or sealed

and

b. weather stripping has been added on openable win-

dows and doors

and

c. caulking or sealants are applied to areas such as

joints around window and door frames,between sole

platesandfloors,betweenwall-ceilingjoints,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 6.

Ifyourhomedoes not meet all of the threecriteriaabove,

proceed to

Determining Fresh-Air Flow For Heater Loca-

tion

, page 5.

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 m3per kw) of the aggregate input rating

of all appliances installed in that space and an unconfined space as

aspacewhosevolumeisnotlessthan50cubicfeetper1,000Btuper

hour (4.8 m3per 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

furnishedwithdoors,are considered apartoftheunconfined 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

Usethis worksheet to determineif youhavea confinedorunconfined space.

Space:Includestheroominwhichyouwillinstallheaterplusanyadjoining

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 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling

height) = 2560 cu. ft. (volume of space)

Ifadditional ventilationto adjoiningroomis suppliedwith grills oropen-

ings, 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:

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 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 com-

bustion air from the outdoors and vents to the outdoors.

Example:

Gas water heater _____________ Btu/Hr

Vent-free heater + _____________ Btu/Hr

Total = _____________ Btu/Hr

WARNING: If the area in which the heater may be

operated is smaller than that defined as an uncon-

fined space or if the building is of unusually tight

construction,provideadequatecombustionandven-

tilation air by one of the methods described in the

National Fuel Gas Code, ANSI Z223.1/NFPA 54 Sec-

tion 5.3

or applicable local codes

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:

51,200 Btu/Hr (maximum the space can support)

60,000 Btu/Hr (actual amount of Btu/Hr used)

Thespaceinthe above example is a confined space because the actual Btu/

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 ex-

tra space provides an unconfined space, remove door to adjoining

roomoradd ventilation grills between rooms. See VentilationAirFrom

Inside Building, page 6.

B. Vent room directly to the outdoors. See Ventilation Air From Out-

doors, page 6.

C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room un-

confined.

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.
