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 supplemental heat (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 insure that water vapor
does not become a problem.
1. Be sure the heater is sized properly for the
application, including ample 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.

FRESH 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/
ANS 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 4
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, l 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
per pa-sec-m
2
) 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 abov,

60,000 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
Inside Building
B. Vent room directly to the outdoors. See
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. Y ou will need no additional fresh air ventilation.
