Confined and Unconfined Space

PROVIDING ADEQUATE

VENTILATION

AIR FOR

The National Fuel Gas Code, ANS Z223.1

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 aggre-

gate 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 input rating of all

appliances installed in that space. Rooms

communicating directly with the space in

whichtheappliancesareinstalled*, through

openings not furnished with doors, are con-

sidered 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

helpreduceheatlossinhomes.Homeowners

weather strip and caulk around windows and

doorstokeepthecoldairoutandthewarmair

in. During heating months, home owners

want their homes as airtight as possible.

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.

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.

* 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 (6 x 10^-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.

Vent-free heater

Gas water heater*

Gas furnace

______________ Btu/Hr

Example:

Gas water heater

40,000 Btu/Hr

Vented gas heater

Gas fireplace logs

Vent-free heater + 33,000 Btu/Hr

Total 73,000 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)

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 maximum 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 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, Section 5.3 or applicable local codes.

Installation Items Needed

• hardware package (provided with heater)

INSTALLING HEATER BASE

ASSEMBLY

1. The fireplace does not meet the clear-

ance to combustibles requirements for

vent-free operation.

• approved flexible gas hose and fittings

(not provided) (if allowed by local codes)

CAUTION: Do not remove the

metal data plates attached to the

heater base assembly. The data

platescontainimportantwarranty

information.

• sealant (resistant to propane/LP gas, not

provided)

2. State or local codes do not permit vent-

free operation.

• electric drill with 3/16" masonry drill bit

3. You prefer vented operation.

1. Apply pipe joint sealant lightly to male

threads of gas fitting (not provided).

Connect approved flexible gas hose to

gas regulator of heater (see Figure 11,

page 11).

If reasons number 1 or 2 above apply to you,

you must permanently open chimney flue

damper. You must install the damper clamp

accessory (to order, see Accessories, page

22). This will insure vented operation (see

Figure 10). The damper clamp will keep

damper open. Installation instructions are

included with clamp accessory.

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.

IMPORTANT: Hold gas regulator with

wrenchwhenconnectingflexiblegashose.

2. Locate mounting brackets, bolts, and nuts

in hardware package. Attach mounting

brackets to heater base (see Figure 12,

page 11). Attach nuts finger tight.

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-

rial. Make sure material is secure.

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.

3. Position heater base assembly in

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

13. Pointing the vent down protects it from

freezing rain or sleet.

We recommend that you install a sediment

trap in supply line as shown in Figure 14.

Locate sediment trap where it is within

reach for cleaning. Install in piping system

betweenfuelsupplyandheater.Locatesedi-

ment trap 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.

ing property damage, personal

injury or loss of life.

Note: You may be running this

heater for the first time after hook-

ing up to gas supply. If so, the con-

trol knob may need to be pressed in

for 30 seconds. This will allow air to

bleed from the gas system.

• You must operate this heater

withafireplacescreeninplace.

Make sure fireplace screen is

closed before running heater.

A. This appliance has a pilot which must

be lighted by hand. When lighting the

pilot, follow these instructions exactly.

6. With control knob pressed in, press

and release ignitor button. This will

light pilot. The pilot is attached to the

front burner. If needed, keep press-

ing ignitor button until pilot lights.

B. BEFORE LIGHTING smell all

around the appliance area for gas. Be

sure to smell next to the floor because

some gas is heavier than air and will

settle on the floor.

NOTICE:Duringinitialoperationof

new heater, burning logs will give

off a paper-burning smell. Orange

flame will also be present. Open

damper or window to vent smell.

This will only last a few hours.

Note: If pilot does not light, contact

a qualified service person or gas sup-

plier for repairs. Until repairs are

made, light pilot with match. To light

pilot with match, see Manual Light-

ing Procedure, page 15.

WHAT TO DO IF YOU SMELL

GAS

• Do not try to light any appliance.

• Do not touch any electric switch; do

not use any phone in your building.

• Immediately call your gas supplier

from a neighbor’s phone. Follow

the gas supplier’s instructions.

• If you cannot reach your gas sup-

plier, call the fire department.

Note: Home owners generally prefer to

operate their heater with the chimney

damper closed. This will put all the heat

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.

7. Keep control knob pressed in for 30

seconds after lighting pilot. After 30

seconds, release control knob.

• If control knob does not pop out

when released, contact a qualified

service person or gas supplier for

repairs.

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.

Note: If pilot goes out, repeat steps

3 through 7.

OPERATION

PILOT FLAME PATTERN

The variable control valve can be set to

anyheatsettingandflameheightdesired,by

simply turning the control knob until that

setting is attained. Even the lowest setting

provides realistic flames and glowing em-

bers from two burners. Selecting higher

settings produces greater heat output. This

results in increased heating comfort.

Figure 24 shows a correct pilot flame pat-

tern. Figure 25 shows an incorrect pilot

flame pattern. The incorrect pilot flame is

not touching the thermocouple. This will

cause the thermocouple to cool. When the

thermocouple cools, the heater will shut
