WATER VAPOR: A BY-PRODUCT OF VENT-FREE ROOM HEATERS
application, including ample combustion and ventilation air.
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.
1. Be sure the heater is sized properly for the
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.
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 Fresh Air for Combustion and Ventilation, pages
5 and 6.

AIR FOR COMBUSTION
AND 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.
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.
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. W alls 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. W eather 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 Determining Fresh-Air Flow for Heater
Location, page 5.
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.
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)
Length×Width×Height=
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)
5
3. Add the Btu/Hr of all fuel burning appliances in the space.

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.
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 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.
Ventilation Air From Inside Building
This fresh air would come from an adjoining unconfined space. W hen 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.
Figure 2 -Ventilation Air from Inside Building
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 required 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.

plumber or gas fitter in the Commonwealth of Massachusetts.
Sellers of unvented propane or natural
gas-fired supplemental room heaters
shall provide to each purchaser a copy
of 527 CMR30 upon sale of the unit.
In the State of Massachusetts,unvented
propane and natural gas-fired space
heaters shall be prohibited in bedrooms and bathrooms.
IMPORTANT: Install an equipment
shut off valve in an accessible
location. The equipment shutoff
valve is for turning on or shutting
off the gas to the appliance.
Apply pipe joint sealant lightly to
male threads. This will prevent
excess sealant from going into pipe.
Excess sealant in pipe could
result in clogged heater valves.
Install sediment trap in supply line
as shown in Figure 12. Locate
sediment trap where it is within
reach for cleaning. Locate sediment trap where trapped matter is
not likely to freeze. A sediment trap
traps moisture and contaminants.
This keeps them
from going into heater controls. If
sediment trap is not installed or is
installed wrong, heater may not run
properly.
