AIR FOR COMBUSTION

AND VENTILATION

WARNING: This ﬁreplace 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 in sure proper fresh air for this and other fuel-burning appliances in your home.

Todayʼs 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 efﬁ cient, 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.

www.desatech.com

PROVIDING ADEQUATE VENTILATION

The following are excerpts from National Fuel Gas Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation.

All spaces in homes fall into one of the three fol lowing ventilation classiﬁcations:

1. Unusually Tight Construction

2. Unconﬁned Space

3. Conﬁned Space

The information on pages 6 through 8 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 out

side atmosphere have a continuous water vapor retarder with a rating of one perm (6 x 10 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 these three

criteria, you must provide additional fresh air. See Ventilation Air From Outdoors, page 8.

If your home does not meet all of the three criteria above, proceed to Determining Fresh-Air Flow For Fireplace Location.

Conﬁned and Unconﬁned Space

The National Fuel Gas Code, ANSI Z223.1/NFPA 54 deﬁnes a conﬁned space as a space whose

volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 m 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 all appliances installed in that space. Rooms com municating 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.

DETERMINING FRESH-AIR FLOW FOR FIREPLACE 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 ﬁreplace 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 16 ft. (length) x 14 ft.

(width) x 8 ft. (ceiling height) = 1792 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. Multiply the space volume by 20 to determine the maximum Btu/Hr the space can support.

__________ (volume of space) x 20 =

(Maximum Btu/Hr the space can support)

Example: 1792 cu. ft. (volume of space) x 20 = 35,840 (maximum Btu/Hr the space can support)

The space in the above example is a conﬁned space because the actual Btu/Hr used is more than the maxi mum 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 adjoin

ing 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 8.

B. Vent room directly to the outdoors. See Ventila

tion Air From Outdoors, page 8.

C. Install a lower Btu/Hr ﬁreplace, 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.
