FRESH AIR FOR
COMBUSTION AND
VENTILATION
WARNING: This heater shall
not be installed in a confined
space unless provisions are provided for adequate combustion
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 fuelburning appliances.
PROVIDING ADEQUATE
VENTILATION
The following is exerpts from National Fuel
Gas Code. NFPA 54/ANSI Z223.1, Section
5.3, Air for Combustion and Ventilation.
All spaces in homes fall into one of the three
following ventilation classifications:
1. Unusually Tight Contruction; 2. Unconfined Space; 3. Confined Space.
The information on pages 3 through 5 will
help you classify your space and provide
adequate ventilation.

Guard
Glass
Panel
Heater
Cabinet
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.
Unusually tight construction is defined as construction where:
a. walls and ceilings exposed to the
outside atmosphere have a continuous water vapor retarder with
a rating of one perm (6x10
per pa-sec-m2) or less with openings gasketed or sealed
b. weather stripping has been
added on openable windows and
doors
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
From Outdoors
If your home does not meet all of the
three criteria above, proceed to page 4.

Confined and Unconfined Space
The National Fuel Gas Code (ANSIZ2123.1,
1992 Section 5.3) defines a confined space
as a space whose volume is less than 50
cubic feet per 1,000 Btu per hour (4.8 m3 per
kw) of the aggregate input rating of all
appliances installed in that space and an
unconfining space as a space whose volume
is not less than 50 cubic feet per 1,000 Btu
per hour (4.8 m3 per kw) of 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 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 worksheet 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 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 20 ft. (length) x 16 ft.
(width) x 8 ft. (ceiling height) =
2560 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. Divide the space volume by 50 cubic
feet to determine the maximum Btu/Hr
the space can support.
__________ (volume of space) ÷ 50
cu. ft. = (Maximum Btu/Hr the space
can support)
Example:
space) ÷ 50 cu. ft. = 51.2 or 51,200
(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 fireplace logs _________ Btu/Hr
Other gas appliances* + ____ Btu/Hr
Total = ____ Btu/Hr
2560 cu. ft. (volume of
Example:
Gas water heater 44,000 Btu/Hr
Vent-free heater + 10,000 Btu/Hr
Total = 54,000 Btu/Hr
* Do not include direct-vent gas appli-
ances. Direct-vent draws combustion
air from the outdoors and vents to the
outdoors.
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:
51,200 Btu/Hr (maximum the space
can support)
54,000 Btu/Hr (actual amount of Btu/
Hr used)
The space in the above example is a confined 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 unconfined space, remove
door to adjoining room or add ventilation grills between rooms. See V entila-
tion Air From Inside Building.
B. Vent room directly to the outdoors. See
V entilation Air Fr om Outdoors, page 5.
C. Install a lower Btu/Hr heater, if lower
Btu/Hr size makes room unconfined.
If the actual Btu/Hr used is less than the
maximum Btu/Hr the space can support, the
space is an unconfined space. You will need
no additional fresh air ventilation.
WARNING: If the area in which
the heater may be operated is
smaller than that defined as an
unconfined space, provide adequate combustion and ventilation air by one of the methods
described in the
Gas Code, ANSI Z223.1, 1992,
Section 5.3
codes.

VENTILATION AIR
Ventilation Air From Inside
Building
This fresh air would come from an adjoining unconfined space. When ventilating to
an adjoining 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 options 1 and 2, Figure 2). You
can also remove door into adjoining room
(see option 3, Figure 2). Follow the Na-
tional Fuel Gas Code NFPA 54/ANSI
Z223.1, Section 5.3, Air for Combustion
and Ventilation for required size of ventila-
tion grills or ducts.
WARNING: Rework worksheet, adding the space of the
adjoining unconfined space. The
combined spaces must have
enough fresh air to supply all
appliances in both spaces.
