WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS

Water vapor is a by-product of gas combustion.An unvented room heater productes 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 ADEQUA TE VENTILATION

The following are excerpts from

National Fuel Gas Code. NFPA 54/ANS Z223.1, Section 5.3.

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.

Air for

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 per pa-sec-m openings gasketed or sealed 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.

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 Example: Space size 20ft. (length) 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)

WARNING: 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, ANS Z223.1, Section 5.3 or applicable local codes.

3. Add the Btu/Hr of all fuel burning appliances in the space.

Vent-free heater Gas water heater* Gas furnace Vented gas heater Gas Fireplace logs Other gas appliances* + Total = *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

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.

CONNECTING TO GAS SUPPLY

WARNING: A qualified

service person must connect heater to gas supply. Follow all local codes.

WARNING: This appliance requires a 3/8 Pipe Thread) inlet connection to the pressure regulator.

WARNING: Never connect heater to private (non-utility) gas well. This gas is commonly known as well-head gas.

IMPORTANT: Check your gas line pressure before connecting heater to gas line. Gas line pressure must be no greater than 10.5 inches of water. If gas line pressure is higher, heater regulator damage could occur.

CAUTION: Use only new, black iron or steel pipe. Internally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of large enough diameter to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur.

Typical Inlet Pipe Diameters

All models up to 20,000 BTU’s use 3/8’’ or greater pipe; All models 25,000 BTU’s and higher, use 1/2” or greater pipe.
