AIR FOR COMBUSTION AND VENTILATION
Unusually tight construction is defi ned as
WARNING: This heater shall not
be installed in a room or space unless the required volume of indoor
combustion air is provided by the
method described in the National
Fuel Gas Code, ANSI Z223.1/NFP A
54, the International Fuel Gas
Code, or applicable local codes.
Read the following instructions
to ensure proper fresh air for this
and other fuel-burning appliances
in your home.
Today’s homes are built more energy effi cient
than ever. New materials, increased insulation
and new construction methods help reduce heat
loss in homes. Homeowners apply weather strip
and caulk around windows and doors to keep
the cold air out and the warm air in. During heating months, homeowners want their homes as
airtight as possible.
While it is good to make your home energy
effi cient, 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, some fi replaces, clothes dryers
and some fuel-burning appliances draw air from
the house to operate. Y ou must provide adequate
fresh air for these appliances. This will ensure
proper venting of vented fuel-burning appliances.
PROVIDING ADEQUA TE VENTILA TION
The following are excerpts from National Fuel
Gas Code, ANSI Z223.1/NFPA 54, Air for Combustion and Ventilation.
All spaces in homes fall into one of the three
following ventilation classifi cations:
1. Unusually Tight Construction
2. Unconfi ned Space
3. Confi ned Space
The information on Pages 8 through 10 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.
126709-01B 7

construction 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
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 fl oors,
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 10.
If your home does not meet all of the three
criteria above, proceed to Determining Fresh-
Air Flow For Firebox Location.
Confi ned and Unconfi ned Space
The National Fuel Gas Code, ANSI Z223.1/
NFPA54 allows two methods for determining
whether the space in which the heater is being
installed is confi ned or unconfi ned space. The
standard method defi nes a confi ned space as a
space whose volume is less than 50 cubic feet
per 1,000 Btu per hour (4.8 m
gregate input rating of all appliances installed in
that space and an unconfi ned space as a space
whose volume is not less than 50 cubic feet per
1,000 Btu per hour (4.8 m
gregate input rating of all appliances installed in
that space. Rooms communicating directly with
the space in which the appliances are installed*,
through openings not furnished with doors, are
considered a part of the unconfi ned space.
Where the air infi ltration rate of a structure is
known, the Known Air Infi ltration Rate Method
may be used. Follow The National Fuel Gas
Code, ANSI Z223.1/NFPA 54 to use this
method to determine if the space is confi ned
or unconfi ned.
* 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 Confi ned or
Unconfi ned Space Using the Standard
Method
AIR FOR COMBUSTION AND VENTILATION
Continued
Use this work sheet to determine if you have
a confi ned or unconfi ned 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
(width) x 8 ft. (ceiling height) = 3,168 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 maximum Btu/Hr the space can support.
________ (volume of space) x 20 = (Maxi-
mum Btu/Hr the space can support)
Example
= 63,360 (maximum Btu/Hr space can support)
3. Add the Btu/Hr of all fuel burning appliances
in the space.
Vent-free fi replace _________Btu/Hr
Gas water heater* _________Btu/Hr
Gas furnace _________Btu/Hr
Vented gas heater _________Btu/Hr
Gas fi replace 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.
Example:
Gas water heater _________Btu/Hr
Vent-free fi replace + _________Btu/Hr
Total = _________Btu/Hr
: Space size 22 ft. (length) x 18 ft.
: 3,168 cu. ft. (volume of space) x 20
40,000
39,000
79,000
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
79,000 Btu/Hr (actual amount of
The space in the example is a confi ned 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
unconfi ned space, remove door to adjoining
room or add ventilation grills between rooms.
See Ventilation Air From Inside Building.
B. Vent room directly to the outdoors. See
Ventilation Air From Outdoors, Page 9.
C. Install a lower Btu/Hr fi replace, if lower Btu/
Hr size makes room unconfi ned.
: 63,360 Btu/Hr (maximum the
space can support)
Btu/Hr used)
If the actual Btu/Hr used is less than the
maximum Btu/Hr the space can support, the
space is an unconfi ned space. You will need
no additional fresh air ventilation.
WARNING: If the area in
which the heater may be operated does not meet the required
volume for indoor combustion
air, combustion and ventilation
air shall be provided by one of
the methods described in the
National Fuel Gas Code, ANSI
Z223.1/NFPA 54, the International Fuel Gas Code, or applicable
local codes.
