AIR FOR COMBUSTION AND VENTILATION
Unusually tight construction is defi ned as
WARNING: This appliance 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/NFPA
54, the International Fuel Gas Code,
or applicable local codes. Read the
following instructions to ensure
proper fresh air for this and other fuelburning appliances in your home.
T oday’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. You must provide
adequate fresh air for these appliances. This
will ensure proper venting of vented fuelburning appliances.
PROVIDING ADEQUA TE
VENTILATION
The following are excerpts from National
Fuel Gas Code ANS 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 7 Through 9 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.

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
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 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 9.
If your home does not meet all of the three
criteria above, proceed to Determining
Fresh-Air Flow for Firebox Location,
Page 8.
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
a space whose volume is less than 50 cubic
feet per 1,000 Btu/hr (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/hr (4.8 m
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 furnished
with doors, are considered a part of the unconfi ned space.
This appliance shall not be installed in a
confi ned space or unusually tight construction
unless provisions are provided for adequate
combustion and ventilation air.
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 FIREBOX LOCATION
Determining if You Have a Confi ned or
Unconfi ned Space Using the Standard
Method
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 appliance 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 maximum Btu/Hr the space can support.
________ (volume of space) x 20 = (Maxi-
mum Btu/Hr the space can support)
Example: 3168 cu. ft. (volume of space) x
20 = 63,360 (maximum Btu/Hr the space can
support)
3. Add the Btu/Hr of all fuel burning appliances
in the space.
Gas water appliance* __________ Btu/Hr
Gas furnace __________Btu/Hr
Vented gas appliance __________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 appliance __________Btu/Hr
Gas fi rebox logs + _________Btu/Hr
Total = _________ Btu/Hr
30,000
+ 10,000
= 40,000
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: 35,840 Btu/Hr (maximum the
space can support)
40,000 Btu/Hr (actual amount of
Btu/Hr used)
The space in the above 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 work sheet, 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, Page 9.
B. Vent room directly to the outdoors. See
Ventilation Air from Outdoors, Page 9.
C. Install a lower Btu/Hr gas log appliance, if
lower Btu/Hr size makes room unconfi ned.
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 appliance 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.
