WATER VAPOR: A BYPRODUC T O F U NV E N T E D R O O M H EAT ER S

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 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.

PROVIDING ADEQUATE VENTILATION

The following are excerpts from

National Fuel Gas Code. NFPA 54/ ANS 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 4 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 per m (6×10-11 kg per pa-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, page 6. If your home does not meet all of the three criteria above see Determining Fresh-Air Flow for Heater Location, page 5.

Confined and

Unconfined Space

The National Fuel Gas Code ANS

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 m3 per kw) of the aggregate input rating of all appliances installed in that space. Rooms communicating directly with

t h e s p a c e	i n w h i c h t h e
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.

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION

Example: 2560 cu. ft. (volume of space)÷ 50 cu.ft.=51.2 or 51.200(maximum Btu/Hr the space can support)

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.

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) 60,000 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. 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, page	5.
B. Vent room directly to		the outdoors. See			Ventilation Air From Outdoors, page 6 .
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.

VENTILATION AIR

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" 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/ANS Z223.1. Section 5.3, Air for Combustion and Ventilation for required size of ventilation grills or ducts

WARNING: 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.
