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 (0.3 Kw) of gas input

per hour. An unvented room heater is intended as a supplemental heater rather than a primary heat

source. 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 ensure that water vapor does not become a problem:

1. Be sure the heater is the proper size for the application, including adequate combustion air and

circulation air.

2. If there is high humidity, a dehumidier 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.

PREPARING FOR INSTALLATION

AIR FOR COMBUSTION AND VENTILATION

CAUTION: This heater shall not be installed in a room or space unless the required volume of

indoor combustion air is provided by the method described in the National Fuel Gas Code, ANSI

Z223.1/NFPA54, the International Fuel Gas Code, or applicable local codes.

PRODUCING ADEQUATE VENTILATION

All spaces in homes fall into one of the three following ventilation classications:

1. Unusually Tight Construction

2. Unconned Space

3. Conned Space

The information on pages 7 through 9 will help you classify your space and provide adequate ventilation.

Conned and Unconned Space

A conned space as 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 unconning space as a

space whose volume is not 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. Rooms connecting directly with the space in

which the appliances are installed*, through openings not furnished with doors, are considered a

part of the unconned space.

This heater shall not be installed in a conned 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 venti-

lation. However, in buildings of unusually tight construction, you must provide additional

fresh air.

Unusually tight construction is dened as construction where:

a) walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder

with a rating of one perm (6x10-11kg per pa-sec-m2) or less with openings gasketed or sealed

and

b) weather stripping has been added on windows that can be opened 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” (page 9). If your home does not meet all of the

three criteria above, proceed to “Determining Fresh-Air Flow For Heater Location”.

PREPARING FOR INSTALLATION

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION

Determining if You Have a Conned or Unconned Space

Use this worksheet to determine if you have a conned or unconned 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 cu. ft. 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)

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 Example:

Gas heater logs __________BTU/hr Gas water heater 30,000 BTU/hr

Other gas appliances*+ ____BTU/hr Vent-free heater + 26,000 BTU/hr

Total = ____BTU/hr Total = 56,000 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 conned 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

unconned space, remove door to adjoining room or add ventilation grills between rooms. See

“Ventilation Air From Inside Building,” page 9.

b) Vent room directly to the outdoors. See “Ventilation Air From Outdoors”, page 9.

c) Install a lower BTU/hr heater if lower BTU/hr size makes room unconned. If the actual BTU/hr

used is less than the maximum BTU/hr the space can support, the space is an unconned space.

You will need no additional fresh air ventilation.

PREPARING FOR INSTALLATION

Ventilation Air From Inside Building

This fresh air would come from adjoining

unconned space. When ventilating to an

adjoining unconned space, you must

provide two permanent openings: one

within 12 in. of the wall connecting

the two spaces (see options 1 and 2,

Fig. 1). You can also remove door into

adjoining room (see option 3, Fig. 1).

Follow the National Fuel Gas Code

NFPA 54/ANS Z223.1. 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 duct. You must provide two

permanent openings: one within 12 in. of

the ceiling and one within 12 in. 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 NFPA

54/ANS Z223.1. 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 unconned space. The

combined spaces must have enough fresh

air to supply all appliances in both spaces.
