AIR FOR
COMBUSTION AND
VENTILATION
Today’s homes are built more energy effi-
cient than ever. New materials, increased
insulation, and new construction methods
helpreduceheatlossinhomes.Homeowners
weather strip and caulk around windows and
doorstokeepthecoldairoutandthewarmair
in. During heating months, home owners
want their homes as airtight as possible.
While it is good to make your home energy
efficient,yourhomeneedstobreathe.Fresh
air must enter your home. All fuel-burning
appliances need fresh air for proper com-
bustion and ventilation.
Exhaustfans,fireplaces,clothesdryers,and
fuel burning appliances draw air from the
house to operate. You must provide ad-
equate fresh air for these appliances. This
will insure proper venting of vented fuel-
burning appliances.
Confined and Unconfined
Spaces
The National Fuel Gas Code ANS Z223.1
defines a confined space as a space whose
volume is less than 50 cubic feet per 1000
Btuperhour(4.8cubicmetersperkw)ofthe
aggregate input rating of all appliances in-
stalledinthatspaceandanunconfinedspace
as a space whose volume is not less than 50
cubic feet per 1000 Btu per hour (4.8 cubic
metersperkw) oftheaggregateinput rating
of all appliances installed in that space.
Rooms communicating directly with the
spaceinwhichtheappliancesareinstalled*,
through openings not furnished with doors,
are considered a part of the unconfined
space.
This heater shall not be installed in a con-
fined space or unusually tight construction
unlessprovisionsareprovided for adequate
combustion and ventilation air.
*Adjoining rooms are communicating only
iftherearedoorlesspassagewaysorventila-
tion grills between them.
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from National
Fuel Gas Code. NFPA 54/ANS Z223.1, Sec-
tion5.3,AirforCombustionandVentilation.
Allspacesinhomesfallintooneofthethree
following ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 4 through 6 will
help you classify your space and provide
adequate ventilation.
Unusually Tight Construction
The air that leaks around doors and win-
dows 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 de-
fined 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 (6 x 10-11 kg
per pa-sec-m2) or less with open-
ings 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, be-
tween sole plates and floors,be-
tween wall-ceiling joints, be-
tween wall panels, at penetra-
tionsforplumbing,electrical,and
gas lines, and at other openings.
If your home meets all of the three
criteria above, you must provide ad-
ditional fresh air. See Ventilation Air
From Outdoors , page 6 .
If your home does not meet all of the
threecriteria above, proceed to Deter-
mining Fresh-Air Flow for Heater Lo-
cation on page 5.
WARNING: This heater shall

tilation air. Read the following in-
structions to insure proper fresh
air for this and other fuel-burning
appliances in your home .

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:Includestheroominwhichyouwillinstallheaterplusanyadjoiningroomswithdoorlesspassagewaysorventilationgrillsbetween
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 18 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) = 2304 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: 2304 cu. ft. (volume of space) ÷50 cu. ft. = 46.1 or 46,100 (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. 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: 46,100 Btu/Hr (maximum the space can support)
50,000 Btu/Hr (actual amount of Btu/Hr used)
ThespaceintheaboveexampleisaconfinedspacebecausetheactualBtu/HrusedismorethanthemaximumBtu/Hrthespacecansupport.
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 adjoin-
ing room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 6.
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 6.
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.

Example:
Gas water heater 40,000 Btu/Hr
Vent-free heater +10,000 Btu/Hr
Total =50,000 Btu/Hr
WARNING:Iftheareainwhichtheheatermaybeoperatedissmallerthanthatdefinedasanunconfinedspace
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, ANS Z223.1, Section 5.3 or applicable local codes.
