Confined and Unconfined Space

PROVIDING ADEQUATE

VENTILATION

AIR FOR

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 m³per kw)

of the aggregate input rating of all appli-

ances installed in that space and an uncon-

fined space as a space whose volume is not

less than 50 cubic feet per 1,000 Btu per

hour (4.8 m³per kw) of the aggregate input

rating of all appliances installed in that

space. Rooms communicating directly with

the space in which the appliances are in-

stalled*, through openings not furnished

with doors, are considered a part of the

unconfined space.

COMBUSTION AND

VENTILATION

The following are excerpts from National

Fuel Gas Code ANSI Z223.1/NFPA 54, Sec-

tion5.3, AirforCombustionandVentilation.

WARNING: This heater shall

notbeinstalledinaconfinedspace

or unusually tight construction

unless provisions are provided

foradequatecombustionandven-

tilation air. Read the following in-

structions to insure proper fresh

air for this and other fuel-burning

appliances in your home.

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.

Today’s homes are built more energy effi-

cient than ever. New materials, increased

insulation, and new construction methods

helpreduceheatlossinhomes.Homeowners

weather strip and caulk around windows and

doorstokeepthecoldairoutandthewarmair

in. During heating months, home owners

want their homes as airtight as possible.

Unusually Tight Construction

* Adjoining rooms are communicating only

iftherearedoorlesspassagewaysorventila-

tion grills between them.

The air that leaks around doors and win-

dows 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 de-

fined as construction where:

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 com-

bustion and ventilation.

a. walls and ceilings exposed to the

outside atmosphere have a con-

tinuous water vapor retarder with

a rating of one perm (6x10^-11kg

per pa-sec-m²) or less with open-

ings gasketed or sealed and

Exhaustfans, fireplaces, clothesdryers, and

fuel burning appliances draw air from the

house to operate. You must provide ad-

equate fresh air for these appliances. This

will insure proper venting of vented fuel-

burning appliances.

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, be-

tween sole plates and floors, be-

tween wall-ceiling joints, be-

tween wall panels, at penetra-

tions for plumbing, electrical, and

gas lines, and at other openings.

If your home meets all of the three

criteria above, you must provide ad-

ditional fresh air. See Ventilation Air

From Outdoors, page 6.

If your home does not meet all of the

three criteria above, proceed to De-

termining Fresh-Air Flow For Heater

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: Includestheroominwhichyouwillinstallheaterplusanyadjoiningroomswithdoorlesspassagewaysorventilationgrillsbetween

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 = (maximum 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.

Vent-free heater

Gas water heater*

Gas furnace

Vented gas heater

Gas fireplace logs

_____________ Btu/Hr

Example:

Gas water heater

Vent-free heater + 31,500 Btu/Hr

Total 71,500 Btu/Hr

40,000 Btu/Hr

Other gas appliances* + _____________ Btu/Hr

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

71,500 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 cansupport.

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 adjoin-

ing room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 6.

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.

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

themethodsdescribedintheNationalFuelGasCode,ANSIZ223.1/NFPA54,Section5.3orapplicablelocalcodes.

or masonry as applicable)

Ifreasons number 1 or 2 above apply toyou,

you must permanently open chimney flue

damper. You must install the damper clamp

accessory (to order, see Accessories, page

24). This will insure vented operation (see

Figure 10). The damper clamp will keep

damper open. Installation instructions are

included with clamp accessory.

• flathead screwdriver

WARNING: You must secure

this heater to fireplace floor. If

not, heater will move when you

adjust controls. Moving heater

may cause a gas leak.

1. Apply pipe joint sealant lightly to male

threads of the fitting to be threaded into

gas control. Connect approved flexible

gas hose to gas control fitting in heater

(see Figure 11, page 11).

See chart below for minimum permanent

flue opening you must provide. Attach

damper clamp so the minimum permanent

flue opening will be maintained at all times.

IMPORTANT: Hold gas fitting with

wrenchwhenconnectingflexiblegashose.

WARNING: If installing in a

sunken fireplace, special care is

needed. You must raise the fire-

place floor to allow access to

heater control panel. This will in-

sure adequate air flow and guard

against sooting. Raise fireplace

floor with noncombustible mate-

CAUTION: Use only new,

black iron or steel pipe. Inter-

nally-tinned copper tubing may

be used in certain areas. Check

should be open with a small blue flame

come blocked by debris or rust, with no

flame present. If so, turn off heater and let

cool. Remove blockage. Blocked burner

flame holes will create soot.

Clean the pilot assembly also. A yellow tip

on the pilot flame indicates dust and dirt in

the pilot assembly. There is a small pilot air

inlet hole about two inches from where the

pilot flame comes out of the pilot assembly

(see Figure 27). With the unit off, lightly

blow air through the air inlet hole. You may
