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 (30ml) of water for every 1,000 BTU’s (.3KW’s) of gas input per hour.
Unvented room heaters are recommended as a supplemental heater (for a room), rather than a primary
heat source (for 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 insure that water vapor does not become a problem.
1. Be sure the heater is sized properly for the application, including adequate combustion air and
circulation air.
2. If high humidity is experienced, a dehumidifier 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 classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 7 through 9 will help you classify your space and provide adequate ventilation.
Confined and Unconfined Space
A confined space is a space whose volume is less than 50 cubic feet per 1,000 BTU per hour (4.8 cubic
meter per kilowatt) of the aggregate input rating of all appliances installed in that space and an
unconfining space as a space whose volume is not less than 50 cubic feet per 1,000 BTU per hour (4.8
cubic meter per kilowatt) 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.
This heater shall not be installed in a confined space or unusually tight construction unless provisions are
provided for adequate combustion and ventilation air.
* Adjoining rooms are communicating only if there are doorless 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 defined as construction where:
a) walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a
rating of one perm (6
×10
-11
kg per pa-sec-m2) or less with openings gasketed or sealed and
b) weather stripping has been added on windows that can be opened 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 f or 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 ab ove, proceed to Determining
Fresh-Air Flow for Heater Location (below).
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: 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 × Width × Height=_____________ cu. ft. (volume of space)
Example: Space size 20ft. (length) × 16ft. (width) × 8ft. (ceiling height) = 2560cu. ft. (volume of space)
If additional ventilation to adj oining room is supplied with grills or openings, add the volume of these
rooms to the total volume of the space.
7
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: 2560 cu. ft. (volume of space) ÷ 50 cu. ft. =51.2 or 51,200(maximum BTU/hr the space can support)
Add the BTU/hr of all fuel burning appliances in the space.

Other gas appliances* +
BTU/hr Total = 56,000 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 that 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 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 8.
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 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 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.
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,
Air for Combustion and Ventilation for required
size of ventilation grills or ducts.
Figure 2 - Ventilation Air Inside Building
8
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, NFPA 54/ ANSI Z223.1. Air for
Combustion and Ventilation for required size
of ventilation grills or ducts.
IMPORTANT: Do not provide openings for inlet
or outlet air into attic if attic has a thermostatcontrolled power vent. Heated air entering the attic will activate the power vent. Rework worksheet,
adding the space of the Adjoining unconfined space. The combined spaces must have enough fresh air to
supply all appliances in both spaces.
INSTALLATION
NOTICE: This heater is intended for use as supplemental heat. Use this heater along with your primary
heating system. Do not install this heater as your primary heat source. If you have a central heating system,
you may run system's circulating blower while using the heater. This will help circulate the heat throughout
the house.
WARNING: A qualified technician person must install the heater. Follow all local codes.
WARNING: Never install the heater.
in a bedroom or bathroom
in a recreational vehicle
where curtains, furniture, clothing, or other flammable objects are less than 42 inches
from the front, top, or sides of the heater
in high traffic areas

CAUTION: This heater creates warm air currents. These currents move heat to wall surfaces next to heater.
Installing heater next to vinyl or cloth wall coverings or operating heater where impurities (such as tobacco
smoke, aromatic candles, cleaning fluids, oil or kerosene lamps, etc.) in the air exist, may cause walls to
discolor.
WARNING: Maintain the minimum clearances. If you can, provide greater clearances from floor, ceiling, and
adjoining side and back walls.
IMPORTANT: Vent-free heaters add moisture to the air. Although this is beneficial, installing heater in rooms
without enough ventilation air may cause mildew to form from too much moisture. See Air for Combustion and
Ventilation, page s 7 through 9.
CHECK GAS TYPE
Use only the type of gas indicated on the plate. If your gas supply cannot meet that requirement, do not install
heater.
CLEARANCES TO COMBUSTIBLES
