Unusually tight construction is defined as 

construction where:

a.  walls and ceilings exposed to the out

-

side  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 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 additional fresh air. 

See 

Ventilation Air From Outdoors

, page 8. 

If your home does not meet all of the three 

criteria  above,  proceed  to 

Determining 

Fresh-Air Flow For Heater Location

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 m

3

 per kw) of the aggregate input 

rating of all appliances installed in that space and 

an unconfined space as a space whose volume is 

not less than 50 cubic feet per 1,000 Btu per hour 

(4.8 m

3

 per kw) of the aggregate input rating of 

all appliances installed in that space. Rooms com

-

municating directly with the space in which the 

appliances are installed*, through openings not 

furnished with doors, are considered a part of the 

unconfined 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

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 pas

-

sageways 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)

tion and ventilation 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, 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. 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. Fresh air must enter 

your home. All fuel-burning appliances need fresh 

air for proper 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 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 fol

-

lowing ventilation classifications:

1.  Unusually Tight Construction

2.  Unconfined Space

3.  Confined Space

The information on pages 6 through 8 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.
