AIR FOR

COMBUSTION

AND

VENTILATION

WARNING ICON G 001

WARNING

This heater shall not be installed in a confined space unless

provisions are provided for adequate combustion and ventila-

tion air. Read the following instructions to insure proper fresh

air for this and other fuel-burning appliances in your home.

Today’s homes are built more energy efficient than ever. New materials, in-

creased 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. During heating months, home owners want their

homes as airtight as possible.

While it is good to make your home energy efficient, your home needs to breathe.

Freshairmustenteryourhome.Allfuel-burningappliancesneedfreshairforproper

combustion and ventilation.

Exhaust fans, fireplaces, clothes dryers, and fuel burning appliances draw air

from the house to operate. You must provide adequate fresh air for these appli-

ances. This will insure proper venting of vented fuel-burning appliances.

Continued

Unconfined Space

The National Fuel Gas Code, ANSIZ223.1, 1992, Section 5.3 defines uncon-

fined space as having a minimum air volume of 50 cubic feet (127 cubic cm)

for each 1000 Btu/Hr input rating of all appliances in the space (cubic feet

equals length x width x height of space). Include adjoining rooms only if there

are doorless passageways or ventilation grills between the rooms.

Confined Space

The National Fuel Gas Code, ANSIZ223.1, 1992, Section 5.3 defines confined

space as having an air volume of less than 50 cubic feet (127 cubic cm) for

each 1000 Btu/Hr input rating of all appliances in the space (cubic feet equals

length x width x height of space). Include adjoining rooms only if there are

doorless passageways or ventilation grills between the rooms.

PROVIDING ADEQUATE VENTILATION

The following is exerpts from National Fuel Gas Code. NFPA 54/ANSI Z223.1,

Section 5.3, Air for Combustion and Ventilation.

All spaces in homes fall into one of the three following ventilation classifica-

tions: 1. Unusually Tight Contruction; 2. Unconfined Space; 3. Confined Space.

The information on pages 5 through 7 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 construc-

tion, you must provide additional fresh air.

Unusually tight construction is defined 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 or less with

openings gasketed or sealed

and

b. weather stripping has been added on openable windows and doors

and

c. caulkingor sealantsareappliedtoareassuchas jointsaroundwindow

and door frames, between sole plates and floors, between wall-ceiling

joints, 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 addi-

tional fresh air. See

Ventilation Air From Outdoors

, page 7

If your home does not meet all of the three criteria above, proceed to page 6.

DETERMINING 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 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 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. 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:

2560 cu. ft. (volume of space) ÷50 cu. ft. = 51.2 or 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

Example:

Gas water heater 40,000 Btu/Hr

Vent-free heater +33,000 Btu/Hr

Total =73,000 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:

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 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 7.

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

If the area in which the heater may be operated is smaller than

that defined as an unconfined space, provide adequate combus-

tion and ventilation air by one of the methods described in the

National Fuel Gas Code, ANSI Z223.1, 1992, Section 5.3.

VENTILATION AIR

Ventilation Air From Inside Building

This fresh air would come from an adjoining unconfined space. When ventilating to an

adjoining unconfined space, you must provide two permanent openings: one within 12" of

theceiling andone within12" ofthefloor onthe wallconnecting thetwo spaces(see options

1 and 2, Figure 2). You can also remove door into adjoining room (see option 3, Figure 2).
