Installation Guidelines — Procedures

INTRODUCTIOIM

Portions of the following instructions have been

adopted in part from the National Fuel Gas Code

(NFPA 54-1984/ANSI Z223 1-1984) copyrighted by

the National Fire Protection Association and American

Gas Association. For further details, consult this

publication, or the current edition available from

National Fire Protection Association, Inc., Batterymarch

Park, Quincy, M A 02269, or American Gas Association,

1515 Wilson Boulevard, Arlington, VA 22209.

These instructions cover minimum requirements and

conform to existing national standards and safety codes

In some instances, these instructions exceed certain local

codes and ordinances, especially those that may not have

kept pace with changing residential construction prac

tices. Carrier requires these standard procedures as a

minimum for a safe installation.

Refer also to regulations of the local gas supplier

as well as to local building, heating, plumbing, or other

codes in effect in area in which installation is made.

A WARNING

Never store items such as the following on, near, or

in contact with the furnace

1. Spray or aerosol cans, rags, brooms, dust mops,

vacuum cleaners, or other cleaning tools.

2. Soap powders, bleaches, waxes or other cleaning

compounds; plastic items or containers; gasoline,

kerosene, cigarette lighter fluid, dry-cleaning

fluids, or other volatile fluids.

3 Paint thinners and other painting compounds.

4. Paper bags or other paper products.

INSPECTION

Available power supply must meet specifications on

furnace rating plate and on all motors in the equipment

Check the available gas supply to see that it conforms

to the gas specification on the AGA rating plate.

LOCATION OF FURNACE AND

AIR FOR VENTILATION

Locate the furnace as near the center of the air distribu

tion system as possible.

Provide ample space for servicing and cleaning. Always

comply with the minimum fire protection clearances

shown on the unit rating plate This furnace must NOT

be installed directly on carpeting, tile, or any combustible

material other than wood flooring.

A CAUTION

Do not install furnace in unconditioned space that

could experience temperatures of 32 F or lower.

NOTE: For proper furnace operation, the furnace must

be installed within 1/2 in of level.

When furnace supply ducts deliver air to areas outside

the space containing the furnace, return air ducts must

also be sealed to furnace casing and must terminate

outside the space containing the furnace. Otherwise, a

negative pressure condition could develop within equip

ment room or space

Furnace Location Relative to Cooling Equip

ment — Install cooling coil in parallel with, or on

downstream side of, furnace to reduce potential for

condensation in heat exchanger. When a coil is installed

in parallel with a furnace, dampers or other means used

to control airflow must prevent chilled air from entering

furnace. For manual damper operation, equip dampers

with a means of preventing operation of either unit unless

damper is in the full-heat or full-cool position.

Special Locations — When installing furnace in a

lesidential garage, protect it from physical damage by

vehicles. Furnaces installed in public garages, airplane

hangars, or other buildings having hazardous atmos

pheres must comply with requirements of the National

Fire Protection Association, Inc.

Ventilation Air — Requirements depend upon

whether the furnace is located in an “unconfined” or

“confined” space:

Unconfined space — A space whose volume is not less

than 50 cu ft/1000 Btuh of the total input rating of all

appliances installed in the space Rooms are considered

a part of the unconfined space when they communicate

through openings not furnished with doors with the

space in which the appliances are installed.

No special ventilating means are required for furnaces

installed in unconfined spaces

Confined space — A space whose volume is less than

50 cu ft/1000 Btuh of the total input ratings of all

appliances installed in that space.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.
