Installation Guidelines—Procedures
INTRODUCTION
Portions of the following instructions have been adopted in
part from the current edition of the National Fuel Gas Code
NFPA No. 54, TIA-54-1984-1/ANSI Z223.1-1984, Z223.1a-
1987 and American Gas Association. For further details,
consult this pubHcation, or the current edition available

These instructions cover
minimum
requirements and con¬
form 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 practices.
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 CAUTION
Application of this furnace shoizld be indoors with spe¬
cial attention given to vent sizing and material, gas
input rate, air temperature rise, and unit sizing.
Improper installation or misapplication of the furnace
can require excessive servicing or cause premature com¬
ponent failure.
This furnace is designed for a minimum continuous return
air temperature of 60 degrees F DB or an intermittent oper¬
ation down to 55 degrees F DB such as when used with a
thermostat night setback.
A WARNING
Never store anything on, or in contact with, the fur¬
nace, such as:
Spray or aerosol cans, rags, brooms, dust mops, vac¬
uum cleaners, or other cleaning tools.
Soap powders, bleaches, waxes or other cleaning com¬
pounds, plastic or plastic containers, gasoline, kerosene,
cigarette lighter fluid, dry-cleaning fluids, or other vola¬
tile fluids.
Paint thinners and other painting compounds, paper
bags or other paper products.
A failure to adhere to this warning can cause corrosion
of the heat exchanger and vent system, fire, personal
injury, or death.

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 A.G.A. rating plate.
FURNACE LOCATION
Locate the furnace as near the center of the air distribution
system as possible.
This furnace may be located in a confined space without
special provisions for dilution or ventilation air.
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 dehver 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 pres¬
sure condition could develop within equipment room or
space.
Furnace Location Relative to Cooling Equipment—Install
cooling coil in parallel with, or on downstream side of, fur¬
nace to reduce potential for condensation in heat exchanger.
When a coil is installed in parallel with a furnace, deimpers
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.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.
