fuel-burning appliances in your

home.

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-

ersweatherstripandcaulkaroundwindows

and doors to keep the cold air out and the

warm air in. During heating months, home

owners want their homes as airtight as pos-

sible.

While it is good to make your home energy

efficient,yourhomeneedstobreathe.Fresh

air must enter your home. All fuel-burning

appliances need fresh air for proper com-

bustion and ventilation.

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.

DETERMINING FRESH-AIR

FLOW FOR HEATER

LOCATION

Determining if You Have a

Confined or Unconfined Space

Usethisworksheetto determineif youhave

a confined or unconfined space.

Space: Includes the room in which you

will install heater 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 open-

ings, 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 sup-

port)

Example:

2560 cu. ft. (volume of

space) ÷50 cu. ft. = 51.2 or 51,200

(maximum Btu/Hr the space can sup-

port)

Unusually Tight Construction

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

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 (6x10-11

kg per pa-sec-m2) or less with

openingsgasketedorsealed

and

b. weather stripping has been

addedonopenablewindowsand

doors

and

c. caulking or sealants are ap-

plied to areas such as joints

aroundwindowanddoorframes,

between sole plates and floors,

between wall-ceiling joints, be-

tweenwallpanels,atpenetrations

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 5

Confined and Unconfined Space

TheNationalFuelGasCode(ANSIZ2123.1,

1992 Section 5.3) defines a confined space

as a space whose volume is less than 50

cubicfeetper1,000Btuperhour(4.8m3per

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 m3 per kw) of the aggregate

inputratingofallappliancesinstalledinthat

space.Roomscommunicating 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.

*Adjoiningroomsarecommunicatingonly

iftherearedoorlesspassagewaysorventila-

tion grills between them.

3. Add the Btu/Hr of all fuel burning ap-

pliances in the space.

Vent-free heater _________ Btu/Hr

Gas water heater*________ Btu/Hr

Gas furnace ____________ Btu/Hr

Vented gas heater ________ Btu/Hr

Gas fireplace logs________ Btu/Hr

Other gas

appliances* + ___________ Btu/Hr

Total = ________________ Btu/Hr

Example:

Gas water heater

40,000 Btu/Hr

Vent-free heater +10,000 Btu/Hr

Total = 50,000 Btu/Hr

* Do not include direct-vent gas appli-

ances. 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:

46,100 Btu/Hr (maximum

the space can support)

50,000 Btu/Hr (actual

amount of Btu/Hr used)

The space in the above example is a con-

fined space because the actual Btu/Hr used

ismorethanthemaximumBtu/Hrthespace

can support. You must provide additional

fresh air. Your options are as follows:

A. Reworkworksheet, adding the space of

an adjoining room. If the extra space

provides an unconfined space, remove

door to adjoining room or add ventila-

tion grills between rooms. See Ventila-

tion Air From Inside Building, page 5.

B. Vent room directly to the outdoors. See

Ventilation Air From Outdoors, page 5.

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

maximumBtu/Hrthespacecansupport,the

spaceisanunconfinedspace.Youwillneed

no additional fresh air ventilation.

CONNECTING

TO GAS

SUPPLY

NOTICE: A qualified service per-

son must connect heater to gas

supply. Follow all local codes.

The installer must supply an external regu-

lator. The external regulator will reduce

incoming gas pressure. You must reduce

Installsedimenttrapinsupplylineasshown

in Figure 13. Locate sediment trap where it

is within reach for cleaning. Locate sedi-

menttrap where trapped matter is not likely

to freeze. A sediment trap traps moisture

and contaminants. This keeps them from

going into heater controls. If sediment trap

is not installed or is installed wrong, heater

may not run properly.

Installation must include a manual shutoff

valve,ground joint union, and plugged1/8"

NPT tap. Locate NPT tap within reach for

test gauge hook up. NPT tap must be up-

stream from heater (see Figure 13).

Apply pipe joint sealant lightly to male

threads. This will prevent excess sealant

fromgoingintopipe. Excess sealant in pipe

could result in clogged heater valves.
