AIR FOR COMBUSTION AND VENTILATION

WARNING

WARNING ICON

G 001

 

 

This heater shall not be installed in a confined space 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.

Today’s homes are built more energy efficient than ever. New materials, increased insulation, and new construction methods help reduce heat loss in homes. Home owners weather strip and caulk around windows and doors to keep the cold air out and the warm air in. During heating months, home owners want their homes as airtight as possible.

While it is good to make your home energy efficient, your home needs to breathe. Fresh air must enter your home. All fuel-burning appliances need fresh air for proper combustion and ventilation.

Exhaust fans, fireplaces, clothes dryers, and fuel burning appliances draw air from the house to operate. You must provide adequate fresh air for these appliances. This will insure proper venting of vented fuel-burning appliances.

PROVIDING ADEQUATE VENTILATION

The following is exerpts 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 Contruction; 2. Unconfined Space; 3. Confined Space.

The information on pages 5 through 7 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 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 7.

If your home does not meet all of the three criteria above, proceed to page 6.

Unconfined Space

The National Fuel Gas Code, ANSIZ223.1, 1992, Section 5.3 defines unconfined space as having a minimum air volume of 50 cubic feet (127 cubic cm) for each 1000 Btu/Hr input rating of all appliances in the space (cubic feet equals length x width x height of space). Include adjoining rooms only if there are doorless passageways or ventilation grills between the rooms.

Confined Space

The National Fuel Gas Code, ANSIZ223.1, 1992, Section 5.3 defines confined

 

space as having an air volume of less than 50 cubic feet (127 cubic cm) for each

 

1000 Btu/Hr input rating of all appliances in the space (cubic feet equals length

 

x width x height of space). Include adjoining rooms only if there are doorless

 

passageways or ventilation grills between the rooms.

DETERMINING AIR FLOW FOR HEATER LOCATION

Determining if You Have a Confined or Unconfined Space

Use this work sheet 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 x width x height).

Length x Width x Height = ___________________ cu. ft. (volume of space) Example: Space size 20 ft. (length) x 16 ft. (width) x 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)

 

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.

* 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 (actual amount of Btu/Hr used)

Example: 51,200

Btu/Hr (maximum the space can support)

73,000

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, page 7.

B.Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 7.

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.

WARNING

WARNING ICON

G 001

If the area in which the heater may be operated is smaller than that defined as an unconfined space, provide adequate combustion and ventilation air by one of the methods described in the

National Fuel Gas Code, ANSI Z223.1, 1992, Section 5.3.

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

A qualified service person must install heater. Follow all local codes.

 

 

 

 

 

 

 

 

NOTICE

 

 

State or local codes may only allow operation of this appliance in a

 

 

vented configuration. Check your state or local codes.

 

 

 

 

 

 

 

 

WARNING

 

 

Before installing in a previously-used wood-burning fireplace, clean

 

 

chimney flue and firebox. Make sure flue is free of any creosote.

 

 

Creosote will ignite if highly heated. Inspect chimney flue for dam-

 

 

age. If damaged, operate heater with flue damper closed.

 

 

 

 

 

 

 

 

WARNING

 

Seal any fresh air vents or ash clean-out doors located on floor or wall

 

of fireplace. If not, drafting may cause pilot outage or sooting. Use a

 

heat-resistant sealant. Do not seal chimney flue damper.

 

 

 

 

 

 

 

WARNING

 

 

Never install the heater

 

 

• in a bedroom or bathroom
