PRODUCING ADEQUATE AIR FOR
COMBUSTION AND VENTILATION
This section is for residential or manufactured (mobile) installation
“This heater shall not be installed in unusually tight construction or unconfined space unless
provisions are adequate for combustion and ventilation air.”
The National Fuel Gas Code, ANSI Z223.1/NFPA 54 defines unusually tight construction or
unconfined space as a space whose volume is less than 50 cubic feet per 1,000 BTU per hour
(4.8m3per kw) of 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 (4.8m3per kw) of the aggregate input rating of all appliances installed in that space.
Rooms communicating directly with space in which appliance are installed, through openings
not furnished with doors, are considered a part of the unconfined space.
“WARNING: IF AREA IN WHICH HEATER MAY BE OPERATED DOES NOT
MEET REQUIRED VOLUME FOR INDOOR COMBUSTION AIR, COMBUSTION
AND VENTILATION AIR SHALL BE PROVIDED BY ONE OF METHODS DE-
SCRIBED IN NATIONAL FUEL GAS CODE, ANSI Z223.1/NFPA 54,INTERNATIONAL
FUEL GAS CODEOR APPLICABLE CODES.”
“WARNING: IF AREA IN WHICH HEATER MAY BE OPERATED IS SMALLER
THAN THAT DEFINED AS AN UNCONFINED SPACE OR IF BUILDING IS OF
UNUSUALLY TIGHT CONSTRUCTION, PROVIDE ADEQUATE COMBUSTION
AND VENTILATION AIR BY ONE OF METHODS DESCRIBED IN NATIONAL
FUEL GAS CODE,ANSI Z223.1/NFPA 54 AIR FOR COMBUSTION AND VENTILA-
TION, OR APPLICABLE LOCAL CODES.”
Unusually tight construction is defined as construction where:
a) Walls and ceilings exposed to outside atmosphere have a continuous water vapor retarder
with a rating of 1 perm (6 x 10-11 kg per 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.
NOTE: SOME AREAS IN UNITED STATES HAVE HIGHER REQUIREMENTS
FOR CUBIC FEET PER 1000 BTU/ HOUR INPUT. (EX. CINCINNATI, OHIO CODES
REQUIRE 70 CUBIC FEET). CHECK YOUR LOCAL CODE BEFORE
INSTALLATION.
DETERMINING FRESH-AIR FLOW FOR
HEATER LOCATION
DETERMINE IF YOU HAVE UNUSUALLY TIGHT CONSTRUCTION OR UNCONFINED SPACE
Use this worksheet to determine if you have unusually tight construction or unconfined space.
SPACE: Includes the room in which you will install heater plus adjoining rooms with
doorless passageways or ventilation grills between rooms.

Page 13
1. Determine volume of space (length x width x height).
Length x Width x Height =_________cu.ft.(volume of space)
EXAMPLE: 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 volume
of these rooms to total volume of space.
2. Divide the space volume by 50 cubic feet to determine maximum BTU/Hr space
can support.
_________(volume of space)/50 cu. ft. =maximum BTU/Hr the space can support)
EXAMPLE: 2560 cu. ft. (volume of space /50 cu. Ft .= 51.2 or
51200 (maximum BTU/Hr the space can support)
3. Add BTU/Hr of all fuel burning appliances in 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
Example: Gas water heater 40000 BTU/Hr
Vent-free heater + 18000 BTU/Hr
Total = 58000 BTU/Hr
*Does not include direct-vent gas appliances. Direct-vent draws combustion air
from outdoors and vents to outdoors.
4. Compare maximum BTU/Hr the space can support with actual amount of BTU/Hr
used.
____________BTU/Hr (maximum the space can support)
____________BTU/Hr (actual amount of BTU/Hr used)
Example: 51200 BTU/Hr (maximum the space can support)
58000 BTU/Hr (actual amount of BTU/Hr used)
The space in above example is a unusually tight construction because actual BTU/Hr used
is more than maximum BTU/Hr space can support. You must provide additional fresh
air. Your options are as follows:
A. Rework worksheet, adding 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 21.
B. Vent room directly to outdoors. See “Ventilation Air From Outdoors”, page 22.
C. Install a lower BTU/Hr heater, if lower BTU/Hr size makes room unconfined.
If actual BTU/Hr used is less than maximum BTU/Hr space can support, space is an
unconfined space. You will need no additional fresh air ventilation.
WARNING:
YOU MUST PROVIDE ADDITIONAL VENTILATION AIR IN UNUSUALLY TIGHT
CONSTRUCTION

Page 14
AIR FOR COMBUSTION AND
VENTILATION INSIDE BUILDING
This fresh air would come from an adjoining unconfined space. When venting to an adjoining
space, you must provide two permanent openings: one within 12" of the ceiling and one within
12" of floor on wall connecting two spaces. (See Options 1 and 2, Figure 5). You can also
remove door into adjoining room. (See Option 3, Figure 5).
WARNING
REWORK WORKSHEET, ADDING SPACE OF ADJOINING UNCONFINED SPACE.
THE COMBINED SPACES MUST HAVE ADEQUATE AMOUNT OF AIR TO SUPPLY
ALL APPLIANCES IN BOTH SPACES.
NOTE: Each opening shall have a minimum free area of 1 square inch per 1000 BTU’s per
hour of total input ratings of all gas utilization equipment in confined space, but not less than
100 square inches.
Figure 5: Ventilation Air From Inside Building
NOTE: Drill holes on bottom of pedestal base on each corner. Unit must be fastened to floor
with screws.

Page 15
AIR FOR COMBUSTION AND
VENTILATION 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. These spaces include attics and crawl spaces. Follow National Fuel
Gas Code NFPA 54/ANSI Z223.1, Section 4.3, “Air For Combustion and Ventilation” for
required size of ventilation grills or ducts. See Figure 6.
IMPORTANT: Do not provide openings for inlet air into attic if attic has a thermostat-
controlled power vent. Heated air entering the attic will activate the power unit.
Figure 6: Ventilation Air From Outdoors
WARNING
THIS HEATER MUST HAVE ADEQUATE AMOUNT OF AIR FOR PROPER
