AIR FOR

WARNING

COMBUSTION

AND

VENTILATION

This heater shall not be installed in a confined space unless

provisions are provided for adequate combustion and ventilation air. Read the following instructions to insure proper fresh air for this and other fuel-burning appliances in your home.

Today's homes are built more energy efficient than ever. New materials, increased

insulation, and new construction methods help reduce heat loss in homes. Home owners weather strip and caulk around windows and doors to keep the cold air out

and the warm air in. During heating months, home owners want their homes as airtight as possible.

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 combustion and ventilation.

Exhaust fans, fireplaces, clothes dryers, and fuel burning appliances draw air from the house to operate. You must provide adequate fresh air for these appliances.

This will insure proper venting of vented fuel-burning appliances.

PROVIDING ADEQUATE VENTILATION

The following is excerpts from National Fuel Gas Code. NFPA 54/ANSI Z223.1, Section 5.3, Air for Combustion and Ventilation.

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.

Unusually Tight Construction

The air that leaks around doors and windows 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 con-

tinuous water vapor retarder with a rating of one perm (6x10 "11per

pa.aec.m =) or less with openings gasketed or sealed and

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, between sole plates and floors, between wall-ceiling Joints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and at other openings.

If your home meets all of the three criteria above, you must provide addi- tional fresh air. See Ventilation Air From Outdoors, page 7.

If your home does not meet all of the three criteria above, proceed to page 6.

10_604

Confined and Unconfined Space The National Fuel Gas Code (ANSIZ223.1, 1992 Section 5.3) defines a confinod

space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 m 3 per 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 m 3per kw) of the aggregate input rating of all appliances installed

in that space. Rooms communicating directly with the space in which the appliances

are installed*, through openings not furnished with doors, are considered apart of the unconfined space.

* Adjoining rooms are communicating only if there are doorless passageways or

ventilation grills between them. Continued _"

DETERMINING 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: 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 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 an fuel burning appliances 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 + 39,000 Btu/Hr Total = 79,000 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/T-Ir(maximum thespacecansupport)

79,000 Btu/Hr (actualamount of BtuiHr 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 wurksheet, adding the space of an adjoining room. If the extra space provides

an unconfined space, remove door to adjoining 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 heatar, if lowar Btu/Hr size makes room unconfined.

Iftbe actual Btu/Hr used is less than the maximum Btu/I-Irthe 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, provide adequate combus- tion and ventilation air by one of the methods described in the

National Fuel Gas Code, ANSI Z223.1, 1992, Section 5.3 or appli- cable local codes.

VENTILATION AIR Ventilation Air From Inside Building

This fresh air would come from an adjoining unconfined space. When ventilating to an adjoining unconfined space, you must provide two permanent openings: one within 12" of the ceiling and one within 12" of the floor on the wall connecting the two spaces (see options 1

and 2, Figure 2). You can also remove door into adjoining room (see option 3, Figure 2). Follow the National Fuel Gas Code NFPA 54/ANSI Z223.1, Section 5.3, Air for Combustion

2nd Ventilation for required size of ventilation grills or ducts.

WARNING

Rework worksheet, adding the space of the adjoining unconfined space. The combined spaces must have enough fresh air to supply all

appliances in both spaces.

Ventilation Air From Outdoors

Provide extra fresh air by using ventilation grills or ducts. You must provide two perma-

nent openings: one within 12"of the ceiling and one within 12" of the floor. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces.

IMPORTANT: Do not provide openings for inlet oroutlet airinto attic if attic has a thermostat- controlled power vent. Heated air entering the attic will activate the power vent.

NOTICE

State or local codes may only allow operation of this appliance in a vented configuration. Check your state or local codes.

WARNING

Before installing in a solid fuel burning fireplace, the chimney flue and firebox must be cleaned of soot, creosote, ashes and loose paint

by a qualified chimney cleaner. Creosote will ignite if highly heated. Inspect chimney flue for damage. If damaged, operate heater with

flue damper closed.

WARNING

Seal any fresh air vents or ash clean-out doors located on floor or wall of fireplace. If not, drafting may cause pilot outage or sooting. Use a

heat-resistant sealant. Do not seal chimney flue damper.

WARNING

Never install the heater

• in a bedroom or bathroom unless installed as ave, nted appli-

• ance (Variable Manually-Controlled Models Only) (see page 13)

• in a recreational vehicle

• where curtains, furniture, clothing, or other flammable objects are less than 36 inches from the front, top, or sides of the heater

• in high traffic areas

• in windy or drafty areas

CAUTION

This heater creates warm air currents. These currents move heat

to wall surfaces next to heater. Installing heater next to vinyl or cloth wall coverings or operating heater where impurities in the air

(such as tobacco smoke) exist, may discolor walls.

IMPORTANT: Vent-free heaters add moisture to the air. Although this is beneficial,

installing heater in rooms without enough ventilation air may cause mildew to form

from too much moisture. See Air for Combustion and Ventilation, pages 5 through 7.

CHECK GAS TYPE

Use only propane gas. If your gas supply is not propane, do not install heater. Call dealer where you bought heater for proper type heater.
