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 fuel-burning appliances.
PROVIDING ADEQUATE VENTILATION
The following is excerpts 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 Construction; 2. Unconfined Space; 3. Confined Space.
The information on pages 5 through 7 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.
Unusually tight construction is defined as construction where:
a. walls and ceilings exposed to the outside atmosphere have a con-
tinuous water vapor retarder with a rating of one perm (6x10
pa•sec•m2) or less with openings gasketed or sealed
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
If your home does not meet all of the three criteria above, proceed to page 6.

Confined and Unconfined Space
The National Fuel Gas Code (ANSIZ223.1, 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 m
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
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 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 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:
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:
Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in the space.
Example:
* Do not include direct-vent gas appliances. 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:
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 Ventilation Air From Inside Building, page 7.
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 7.
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.
Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) =
2560 cu. ft. (volume of space)
2560 cu. ft. (volume of space) ÷ 50 cu. ft. = 51.2 or 51,200 (maximum

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
National Fuel Gas Code, ANSI Z223.1, 1992, Section 5.3
or appli-
cable local 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 National Fuel Gas Code NFPA 54/ANSI Z223.1, Section 5.3, Air for Combustion
and Ventilation for required size of ventilation grills or ducts.
