WATER VAPOR: A BY-PRODUCT OF VENT-FREE ROOM HEATERS

Water vapor is a by-product of gas combustion. An ventfree room heater products approximately one (1) ounce

(30ml) of water for every 1,000 BTU’s (.3KW’s) of gas input per hour.

Ven t-free roo m h eaters are rec o mm end ed as 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 application, including ample combustion and ventilation 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 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. Walls 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-m 2 ) 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 Deter- mining 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 m 3 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 m 3 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 ai r.

* 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

Length

× width × height).

× Width × Height= cu.ft. (volume of space)

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.

Vent-free heater Btu/Hr

Gas water heater* Btu/Hr

Gas furnace Btu/Hr

Vented gas heater Btu/Hr

Gas Fireplace logs Btu/Hr

Other gas appliances* + Btu/Hr

Total = Btu/Hr

Example:

Gas water heater 40,000 Btu/Hr

Vent free heater + 18,000 Btu/Hr

Total = 58,000 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)

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.

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

Ventilation Air From Inside 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 one within 12

"

of the ceiling and

"

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 Com-

bustion 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

12

"

"

of the floor.

of the ceiling and one within

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 Venti-

lation 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.
