AIR FOR COMBUSTION AND VENTILATION

WARNING

This fireplace 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, fireboxes, 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.

AIR FOR COMBUSTION AND VENTILATION

Providing adequate ventilation

The following is 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 7 through 11 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 (6x10

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.

per pa-sec-m2) or less

If your home meets all of the three criteria above, you must provide additional fresh air. See Ventilation Air From Outdoors, page 11.

If your home does not meet all of the three criteria above, proceed to page 9.

Confined Space and Unconfined Space

The National Fuel Gas Code (ANSI Z223.1, 1992 Section 5.3) defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 BTU per hour (4.8m3 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 (4.8m3 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.

* Adjoining rooms are communicating only if there are doorless passageways or ventilation grills between them.

AIR FOR COMBUSTION AND VENTILATION

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 the firebox 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 22 ft. (length) x 18 ft. (width) x 8 ft. (ceiling height) =

3168 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: 3168 cu. Ft. (volume of space) 50 cu. Ft. = 63.3 or 63,300 (maximum

BTU/Hr the space can support)

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

Vent-free Firebox __________________ BTU/Hr Gas water heater* __________________ BTU/Hr Gas furnace __________________ BTU/Hr Vented gas heater __________________ BTU/Hr Gas firebox logs __________________ BTU/Hr Other gas appliances* + __________________ BTU/Hr Total = __________________ BTU/Hr

Example: Gas water Heater 40,000 BTU/Hr

Vent-free firebox with log heater + 39,000 BTU/Hr

Total = 79,000 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: 63,300 BTU/Hr (maximum the space can support) 79,000 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 10.
