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.
