Water vapor is a by-product of gas combustion. An ventfree room heater produces approximately one (1) ounce
(30ml) of water for every 1,000 BTU’s (.3KW’s) of gas
input per hour.
Vent-free room heaters are intended for supplemental heat
(a room) rather than a primary heat source (an entire house).
In most supplemental heat application, the water vapor does
not create a problem. In most applications, the water vapor
enhances the low humidity atmosphere experience during
cold weather.
The following steps will help insure that water vapor does
not become a problem.
WATER VAPOR: A BY-PRODUCT OF VENT-FREE ROOM HEATERS
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 a vent-free room heater as the primary heat
source.

AIR FOR COMBUSTION
AND VENTILATION
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from
National Fuel Gas Code. NFPA
54/ANSI Z223.1, 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
through 6 will help you classify
your space and provide adequate
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.
Confined and
Unconfined Space
The National Fuel Gas Code
ANSI Z223.1 defines a confined
space as a space whose volume
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.
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 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. If your home meets
all of the three criteria above, you
must provide additional fresh air.
See Ventilation Air From
Outdoors, page 6.
If your home does not meet all of the
three criteria above, see Determin-
ing Fresh-Air Flow for Heater
Location, page 5.
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).
Length×Width×Height= cu.ft. (volume of space)
Example: Space size20ft. (length)×16ft.( width)×8ft. (ceiling height)=2560cu. 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: 2560 cu. ft. (volume of space)÷50 cu.ft.=51.2 or 51.200(maximum Btu/Hr the space can support)
6
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.
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. Section 5.3, Air
for Combustion and Ventilation for required
size of ventilation grills or ducts.
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 + 18,000 Btu/Hr
Total = 58,000 Btu/Hr
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 : 51,200 Btu/Hr(maximum the space can support)
58,000 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
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors
C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room unconfined.
Figure 2 -Ventilation Air from Inside Building
Figure 3 -Ventilation Air from Outdoors
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, Section 5.3. Air
for Combustion and Ventilation for re-
quired size of ventilation grills or ducts.
IMPORTANT: Do not provide openings for
inlet or outlet air into attic if attic has a
thermostat-controlled power vent.
Heated air entering the attic will activate
the power vent.
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, Air for Combustion and Ventilation, or
applicable local codes.
