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 intended
as supplemental heat (a room) rather
that 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 atmospheres 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 of the
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.

1. This appliance is only for use with
the type of gas indicated on the rat­ing plate. This appliance is not con­vertible for use with other gases.

2. Do not place Propane/LP supply tank
(s) inside any structure. Locate Pro­pane/LP supply tank(s) outdoors.

3. If you smell gas

lShut off gas supply.
lDo not try to light any appliance.
lDo not touch any electrical switch:

do not use any phone in
your building.
lImmediately call your gas supplier

from a neighbor’s phone.

Follow the gas supplier’s

instructions.
lIf you cannot reach your gas
supplier, call the fire department.

4. This heater shall not be installed in
a bedroom or bathroom.

5. Do not use this heater as a wood­burning heater. Use only the logs
provided with the heater.

6. Do not add extra logs or ornaments
such as pine cones, vermiculite, or
rock wool. Using these added items
can cause sooting. Do not add lava
rock around base. Rock and debris
could fall into the control area of
heater. After servicing, always re­place screen before operating
heater.

7. This heater is designed to be
smokeless. If logs ever appear to
smoke, turn heater off and call a
qualified service person. Note: Dur­ing initial operation, slight smoking
could occur due to log curing and
heater burning manufacturing
residues.

8. To prevent the creation of soot, fol­low the instructions in Cleaning and

Maintenance.

9. This heater needs fresh air ventila­tion to run properly. This heater has
an Oxygen Depletion Sensing
(ODS) safety shutoff system. The
ODS shuts down the heater if not
enough fresh air is available. See

Air for Combustion and Ventilation,

pages 5 through 6. If heater keeps
shutting off, see Troubleshooting,
pages 17 through 19.

10. Keep all air openings in front and
bottom of heater clear and free of
debris. This will insure enough air
for proper combustion.

11. If heater shuts off. Do not relight un­til you provide fresh, outside air. If
heater keeps shutting off, have it
serviced.

12. Do not run heater:

l Where flammable liquids or
vapors are used or stored.
lUnder dusty conditions.

13. Before using furniture polish, wax,
carpet cleaner, or similar products,
turn heater off. If heated, the vapors
from these products may create a
white powder residue within burner
box or on adjacent walls or furniture.

14. Do not use this heater to cook food
or burn paper or other objects.

15. Do not use heater if any part has
been under water. lmmediately call
a qualified service technician to in­spect the room heater and to re­place any part of the control system

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.

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
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.
If your home does not meet all of the
three criteria above, proceed to Deter-

mining Fresh-Air Flow For Heater
Location.

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 size 20ft. (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.
Vent-free heater Btu/Hr
Gas water heater* Btu/Hr
Gas furnace Btu/Hr
Vented gas heater Btu/Hr
Gas heater logs Btu/Hr

Example:
Gas water heater 30,000 Btu/Hr
Vent-free heater + 26,000 Btu/Hr

Total = 56,000 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)

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.
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.

NOTE: 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, Section 5.3 or applicable local codes.

Ventilation Air From lnside 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.

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.
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.
