AIR FOR COMBUSTION AND VENTILATION
W ARNING: 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 insure
proper fresh air for this and
other fuel-burning 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. Home owners weather
strip and caulk around windows and doors to
keep cold air out and warm air in. During heating months, home owners 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, fi reboxes, clothes dryers and
fuel burning appliances draw air from the
house to operate. Y ou must provide adequate
fresh air for these appliances. This will insure
proper venting of vented fuel-burning appliances.
PROVIDING ADEQUA TE
VENTILATION
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
Information on page 7 through 9 will help you
classify your space and provide adequate
ventilation.
Unusually Tight Construction
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.
Unusually tight construction is defi ned as
construction where:
a. walls and ceilings exposed to outside
atmosphere have a continuous water
vapor retarder with a rating of one
perm (6 x 10
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 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 three criteria above,
you must provide additional fresh air. See
Ventilation Air From Outdoors, page 9.
If your home does not meet all
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 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
of the aggregate 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
3
per kw) of the aggregate input rating of
m
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
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: 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.
Vent-free heater _______ 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*
TotaL = _______ Btu/Hr
* Do not include direct-vent gas appli-
ances. Direct-vent draws combustion
air from the outdoors and vents to the
outdoors.
Example:Gas water heater _________ Btu/Hr
Vent-free heater + ________ Btu/Hr
Total = ________ Btu/Hr
+ _______ Btu/Hr
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: 63,360 Btu/Hr (maximum
the space can support)
79,000 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 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, page 9.
B. Vent room directly to the outdoors. See
Ventilation Air From Outdoors, page 9.
C. Install a lower Btu/Hr heater, 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 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/NFP A 54,
the International Fuel Gas Code,
or applicable local codes.
