AIR FOR COMBUSTION
AND VENTILATION
WARNING: This heater shall not be installed in a confined space or unusually tight con­struction 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 are excerpts from National Fuel Gas Code, ANSI Z223.1/NFPA 54, 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 through76 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 out-
side atmosphere have a continuous water vapor retarder with a rating of one perm (6x10 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 ar-
eas 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 Ventilation page 7.
If your home does not meet all of the three criteria above, proceed to
Fresh-Air Flow For Heater Location
Confined and Unconfined Space
The National Fuel Gas Code, ANSI Z223.1/NFPA 54 defines a confined space as a space whose vol-
ume 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 un­confined 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 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: 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. Multiply the space volume by 20 to determine the maximum Btu/Hr the space can support.
_______ (volume of space) x 20 = (Maximum
Btu/Hr the space can support)
Example:
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 * Do not include direct-vent gas appliances. Di-
rect-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
4. Compare the maximum Btu/Hr the space can support with the actual amount of Btu/Hr used.
2560 cu. ft. (volume of space) x 20 =
40,000 20,000 60,000
______________ 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) 60,000 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 ad-
joining room. If the extra space provides an un­confined space, remove door to adjoining room or add ventilation grills between rooms. See Ven- tilation Air From Inside Building, page 7.
B. Vent room directly to the outdoors. See Ventila-
tion 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.
WARNING: If the area in which the heater may be oper­ated is smaller than that defined as an unconfined space or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of the methods described in the
National Fuel Gas Code,
ANSI Z223.1/NFPA 54 Section
5.3
or applicable 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, ANSI Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation for required size of
ventilation grills or ducts.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or ducts. You must provide two permanent open­ings: one within 12" of the ceiling and one within 12" of the floor. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces. Follow the
National Fuel Gas Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation
for required size of ventilation grills or ducts.
IMPORTANT:
