PRODUCT IDENTIFICATION
WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS
Water vapor is a by-product of gas combustion. An unvented room heater produces approximately one (1) ounce (30 mL) of
water for every 1,000 BTUs (.3 kw) of gas input per hour. An unvented room heater is recommended as a supplemental heater
(a room) rather than a primary heat source (an entire house). In most supplemental heat applications, the water vapor does
not create a problem. In most applications, the water vapor enhances the low humidity atmosphere experienced during cold
weather.
The following steps will help ensure that water vapor does not become a problem:
1. Be sure the heater is the proper size for the application, including adequate combustion air and circulation air.
2. If there is high humidity, a dehumidier may be used to help lower the water vapor content of the air.
3. Do not use an unvented room heater as the primary heat source.

AIR FOR COMBUSTION AND VENTILATION
WARNING: If the area in which the heater may be operated does not meet the required volume for indoor combustion air,
combustion and ventilation air shall be provided by one of the methods described in the National Fuel Gas Code,
ANSI Z223.1/NFPA 54, the International Fuel Gas Code, or applicable local codes.
PRODUCING ADEQUATE VENTILATION
All spaces in homes fall into one of the three following ventilation classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
The information on pages 8 through 9 will help you classify your space and provide adequate ventilation.
Conned and Unconned Space
A conned space is a space whose volume is less than 50 cu. ft. per 1,000 BTU/hr (4.8 m^3 per kw) of the aggregate input rating of
all appliances installed in that space and an unconned space as a space whose volume is not less than 50 cu. ft. per 1,000 BTU/
hr (4.8 m^3 per kw) of the aggregate input rating of all appliances installed in that space. Rooms connecting directly with the space
in which the appliances are installed*, through openings not furnished with doors, are considered a part of the unconned space.
This heater shall not be installed in a conned space or unusually tight construction unless provisions are provided for adequate
combustion and ventilation air.
* Adjoining rooms are connecting only if there are door-less passageways or ventilation grills between them
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 dened 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
-
11
kg per pa-sec-m2) or less with openings gasket or sealed and
b) weather stripping has been added on windows that can be opened and on doors and
c) caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and oors,
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 Air From Outdoors” (page 9). If your home does not meet all of the three criteria above, proceed to “Determining
Fresh-Air Flow For Heater Location”.

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION
Determining if You Have a Conned or Unconned Space
Use this worksheet to determine if you have a conned or unconned space.
Space: Includes the room in which you will install heater plus any adjoining rooms with door-less passageways or ventilation
grills between the rooms.
1. Determine the volume of the space Length × Width × Height = cu. ft. (volume of space)
Example: Space size 20 ft. (length) × 16 ft.(width) × 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 cu. ft. to determine the maximum BTU/hr the 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 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 Example:
Gas heater logs ________ BTU/hr Gas water heater 30,000 BTU/hr
Other gas appliances*+ ___BTU/hr Vent-free heater +26,000 BTU/hr
Total =________________ BTU/hr Total =56,000 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 : 51,200 BTU/hr (maximum the space can support)
56,000 BTU/hr (actual amount of BTU/hr used)
The space in the above example is a conned 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 unconned space, remove door to
adjoining room or add ventilation grills between rooms. See “Ventilation Air From Inside Building,” page 9.
b) Vent room directly to the outdoors. See “Ventilation Air From Outdoors”, Page 9.
c) Install a lower BTU/hr heater if lower BTU/hr size makes room unconned. If the actual BTU/hr used is less than the
maximum BTU/hr the space can support, the space is an unconned space. You will need no additional fresh air ventilation.
