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
(30 mL) of water for every 1,000 BTUs (.3 KWs) 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 applica-
tions, 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 ensure 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 dehumidier 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.
UNPACKING
1. Remove heater from carton.
2. Remove all protective packaging applied to heater for shipping
3. Check heater for any shipping damage. If heater is damaged, promptly inform dealer where you bought heater.

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.
Providing Adequate Ventilation
All spaces in homes fall into one of the three following ventilation classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
The information on pages 8 through 10 will help you classify your space and provide adequate ventilation.
Conned and Unconned Space
A conned space is a space whose volume is less than 50 cu. ft. per 1,000 BTU/hr (4.8 m^3 per kw) of the aggregate
input rating of all appliances installed in that space and an unconned space as a space whose volume is not less than
50 cubic feet per 1,000 BTU/hr (4.8 m^3 per kw) of the aggregate input rating of all appliances installed in that space.
Rooms connecting directly with the space in which the appliances are installed*, through openings not furnished with
doors, are considered a part of the unconned space.
This heater shall not be installed in a conned space or unusually tight construction unless provisions are provided for
adequate combustion and ventilation air.
* Adjoining rooms are connecting 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 dened as construction where:
a) Walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of one
perm (6×10-11kg per pa-sec-m2) or less with openings gasketed or sealed and
b) Weather stripping has been added on openable windows and on doors and
c) Caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and
oors, 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 “Determining Fresh-Air Flow For
Heater Location”.

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION
Determining if You Have a Conned or Unconned Space
Use this worksheet to determine if you have a conned or unconned 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 20 ft. (length) × 16 ft. (width)×8 ft. (ceiling height) =2560 cu. 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)
3. Add the BTU/hr of all fuel burning appliances in the space.
*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 conned 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 ”
on next page.
b) Vent room directly to the outdoors. See “ Ventilation Air From Outdoors ” on next page.
c) Install a lower BTU/hr heater if lower BTU/hr size makes room unconned. If the actual BTU/hr used is less
than the maximum BTU/hr the space can support, the space is an unconned space. You will need no
additional fresh air ventilation.
Example:
Gas water heater 30,000 BTU/hr
Vent-free heater + 26,000 BTU/hr
Total = 56,000 BTU/hr

Figure 2 - Ventilation Air from Inside Building
NOTE: Base not included. Not for use in
bedrooms or bathrooms.
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 lnside Building
This fresh air would come from an adjoining unconned
space. When ventilating to an adjoining unconned
space, you must provide two permanent openings: one
within 12 inches of the ceiling and one within 12 inches
of the oor on the wall connecting the two spaces
(see options 1 and 2, Figure 2). You can also remove
the door into adjoining room (see option 3, Figure 2).
Follow the National Fuel Gas Code. ANSI Z223.1/
NFPA 54, Air for Combustion and Ventilation for
required size of entilation 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 inches of the ceiling and one within 12 inches
of the oor. 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, ANSI Z223.1/ NFPA 54, 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 unconned space. The combined spaces
must have enough fresh air to supply all appliances in
both spaces.
