OWNER’S MANUAL

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 5 through 7 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

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 (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 7.

If your home does not meet all of the

three criteria above, proceed to De-

termining Fresh-Air Flow For Fire-

place Location, page 6.

DETERMINING FRESH-AIR FLOW FOR FIREPLACE LOCATION

Determining if You Have a Confined or Unconfined Space

Use this worksheet 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 = (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.

Btu/Hr

Total

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)

56,000 Btu/Hr (actual amount of Btu/Hr used)

The space in the above example is a confinedspace 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 7.

B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 7.

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 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

themethodsdescribedintheNationalFuelGasCodeANSIZ223.1/NFPA54, Section5.3orapplicablelocalcodes.

Use extension cord if needed. The cord must

have a three-prong, grounding plug and a

three-hole receptacle. Make sure cord is in

good shape. It must be heavy enough to carry

the current needed. An undersized cord will

cause a drop in line voltage. This will result

in loss of power and overheating. Use a No.

16 AWG cord for lengths less than 50 feet.

IMPORTANT:Check gas line pressure be-

fore connecting fireplace to gas line. Gas

line pressure must be no greater than 14

from going into pipe. Excess sealant in pipe

could result in clogged fireplace valves.

CAUTION: Use only new,

black iron or steel pipe. Inter-

nally-tinned copper tubing may

be used in certain areas. Check

your local codes. Use pipe of

1/2" or greater diameter to al-

We recommend that you install a sediment

trap in supply line as shown in Figure 23.

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 fireplace controls. If sediment

trap is not installed or is installed wrong,

fireplace may not run properly.

Note: Floor anchors and mounting screws

are in hardware package. The hardware

package is provided with fireplace.

1. Drill holes at marked locations using

5/16" drill bit. For solid floors (con-

crete or masonry), drill at least 1" deep.

Installation must include an equipment

shutoff valve, union, and plugged 1/8" NPT

tap. Locate NPT tap within reach for test

gauge hook up. NPT tap must be upstream

from fireplace (see Figure 23).
