Confined and Unconfined Space

PROVIDING ADEQUATE

VENTILATION

AIR FOR

The National Fuel Gas Code (ANS 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 (4.8 m³per

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 m³per kw) of the aggregate

inputratingofallappliancesinstalledinthat

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. NFPA 54/ANS Z223.1, 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

help reduce heat loss in homes. Home own-

ers weather strip and caulk around windows

and doors to keep the cold air out and the

warm air in. During heating months, home

ownerswanttheirhomesasairtightaspossible.

Unusually Tight Construction

This heater shall not be installed in a con-

fined space or unusually tight construction

unless provisions are provided for adequate

combustion and ventilation air.

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.

* Adjoining rooms are communicating only

iftherearedoorlesspassagewaysorventila-

tion grills between them.

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. 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.

Vented gas heater

Other gas appliances* +

_____________ Btu/Hr

Example:

Vent-free heater

Total

40,000

39,000

79,000

Btu/Hr

Total

* 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)

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 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

the methods described in the National Fuel Gas Code, ANS Z223.1, 1992, Section 5.3 or applicable local codes.

The installer must supply an external regu-

lator. The external regulator will reduce

incoming gas pressure. You must reduce

incominggaspressuretobetween11and14

inches of water. If you do not reduce incom-

ing gas pressure, heater regulator damage

could occur. Install external regulator with

the vent pointing down as shown in Figure

freezing rain or sleet.

CAUTION: Avoid damage to

into the room. However, there may be

times you will desire the full flames of the

High heat setting but will find the heat

output excessive. You can open the chim-

ney damper (if you have one) fully or

partially to release some of the heat.

Note: If pilot does not stay lit, con-

tact a qualified service person or gas

supplier for repairs. Until repairs are

made, light pilot with match. To light

pilot with match, see Manual Light-

ing Procedure on page 15.

C. Use only your hand to push in or turn

the gas control knob. Never use tools.

If the knob will not push in or turn

by hand, don’t try to repair it, call a

qualified service technician or gas

supplier. Force or attempted repair

may result in a fire or explosion.

WARNING: Damper handle

will be hot if heater has been

running.

D. Do not use this appliance if any part

has been under water. Immediately

call a qualified service technician to

inspect the appliance and to replace

any part of the control system and

any gas control which has been un-

der water.

with the heater running. All slotted burner

flame holes should be open with yellow

flame present. All round burner flame holes

should be open with a small blue flame

present. Some burner flame holes may be-

come blocked by debris or rust, with no

flame present. If so, turn off heater and let

cool. Either remove blockage or replace

burner. 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 26). With the unit off, lightly

blow air through the air inlet hole. You may
