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.

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.

113109-01B 5

www.desatech.com

AIR FOR COMBUSTION

AND VENTILATION

Continued

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 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 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 ven tilation. 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 7.

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

www.desatech.com

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

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 m

per kw) of the aggregate input rating of 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 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 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 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. Multiply the space volume by 20 to determine

the maximum Btu/Hr the space can support.

__________ (volume of space) x 20 = (Maxi-

mum Btu/Hr the space can support)

Example: 2560 cu. ft. (volume of space) x 20 =

51,200 (maximum Btu/Hr the space can support)

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

the space.

the two spaces (see options 1 and 2, Figure 3). You can also remove door into adjoining room (see option 3, Figure 3). Follow the National Fuel Gas

Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation for required size of

ventilation grills or ducts.

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 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.

B. Vent room directly to the outdoors. See Ventila

tion Air From Outdoors.

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 uncon-

ﬁned space. You will need no additional fresh air ventilation.

WARNING: If the area in which the ﬁreplace may be operated is smaller than that deﬁned as

Figure 3 - Ventilation Air from Inside

Building

Ventilation Air From Outdoors

Provide extra fresh air by using ventilation grills or ducts. You must provide two permanent openings:

one within 12" of the ceiling and one within 12" of the ﬂoor. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces. Follow the

National Fuel Gas Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation for

required size of ventilation grills or ducts. IMPORTANT: Do not provide openings for inlet

or outlet air into attic if attic has a thermostatcontrolled power vent. Heated air entering the attic will activate the power vent.
