Unusually Tight Construction

The air that leaks around doors and windows may provide

enoughfreshairforcombustionandventilation.However,in

buildings of unusually tight construction, you must provide

additional fresh air.

Unusually tight construction is

defined

as con

-

struction where:

a. walls and ceilings exposed to the outside

atmosphere have a continuous water vapor

retarder with a rating of one perm (6 x 10

-11

kg

per pa-sec-m

2

) or less with openings 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,

between sole plates and

floo

rs, between wall-

ceiling joints, between wall panels, at penetra

-

tions 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

tion Air From Outdoors

, page 5.

If your home does not meet all of the three criteria

above, proceed to

VENTILATION AIR

Ventilation Air From Inside Building 

Ventilation Air From Outdoors

Provide extra fresh air by using ventilation grills or ducts.

You must provide two permanent openings: one within

12" of the ceiling and one within 12" of the

floor.

Follow the National Fuel Gas Code ANSI Z223.1/NFPA

54, Section 5.3, Air for Combustion and Ventilation for

required size of ventilation grills or ducts. 

IMPORTANT:

Do not provide openings for inlet or outlet

air into attic if attic has a thermostat-controlled power vent.

Heated air entering the attic will activate the power vent.

DETERMINING FRESH-AIR FLOW

FOR APPLIANCE LOCATION

Determining if You Ha

ve 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 appli-

ance 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 maxi-

mum Btu/Hr the space can support.

_______ (volume of space) x 20 = (Maximum Btu/Hr

the space can support)
Example: 3168 cu. ft. (volume of space) x 20 = 63,360

(maximum Btu/Hr the space can support)

This fresh air would come from an adjoining un-

confined space. When ventilating to an adjoin-

ing unconfined space, you must provide two 

permanent openings: one within 12" of the 

ceiling and one within 12" of the floor on the 

wall connecting the two spaces (see Figure 1). 

You can also remove door into adjoining room 

(see Figure 1). Follow the National Fuel Gas 

Code ANSI Z223.1/NFPA 54, Sec-tion 5.3, Air for 

Combustion and Ventilation for required size of 

ventilation grills or ducts.
