Carrier 100 Series - Introduction; Location; General; Respect to Cooling Equipment

INTRODUCTION
The Model 58TUA, Series 100 Furnace is available in sizes 40,000
through 140,000 Btuh input capacities.
The design of the upflow gas-fired furnace is A.G.A./C,G.A.
certified for use with natural and propane gases and for installation
on combustible flooring, in alcoves, attics, basements, closets, or
utility rooms. The design of this furnace line is NOT A.G.A,/
C.G.A. certified for installation in mobile homes, recreation
vehicles, or outdoors.
Before installing the furnace, refer to the current edition of the
National Fuel Gas Code NFPA No. 54-1992/ANSI Z223.1-1992.
Canadian installations must be installed in accordance with
CAN/CGA-B149 Installation Codes and all authorities having
jurisdiction. For further information, the National Fuel Gas Code is
available from National Fire Protection Association Inc. Battery-
march Park, Quincy, MA 02269, American Gas Association, 1515
Wilson Boulevard, Arlington, VA 22209, or from Literature
Distribution.
Installation must conform to the regulations' of the serving gas
supplier and the local building, heating, and plumbing codes in
effect in the area in which the installation is made, or in the
absence of local codes, with the requirements of the National Fuel
Gas Code.
A CAUTION
Application of this furnace should be indoors with special
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 component failure.
This furnace is designed for a minimum continuous return-air
temperature of 60°F db or intermittent operation down to 55°F db
such as when used with a night setback thermostat. Return-air
temperature must not exceed 85°F db.
To aid in installation, trouble shooting, and service, a status code
label is located on the blower compartment door. This label
explains how to use the LED status indicator on the furnace control
which is viewed through the sightglass on the door.
For high altitude installations, the high altitude conversion kit
MUST be installed for conventional Category I (negative pressure)
vertical vents at or above 5500 ft above sea level. For Category III
vertical or horizontal high temperature plastic Special Gas Vents,
the kit must be installed at or above altitudes of 4000 ft above sea
level.
For accessory installation details, refer to the applicable instruction
literature.
NOTE: Remove all shipping brackets and materials before
operating the furnace.
Step 1—LOCATION
GENERAL
This furnace must be installed so the electrical components are
protected from water.
Locate the furnace as near the center of the air distribution system
as possible. The furnace should be installed as level as possible.
When a furnace is installed so that the supply ducts carry air to
areas outside the space containing the furnace, the return air must
also be handled by a duct(s) sealed to the furnace casing and
terminating outside the space containing the furnace.
When venting vertically with Category I vent materials, locate
furnace close to the chimney or vent.
Provide ample space for servicing and cleaning. Always comply
with the minimum fire protection clearances shown on the unit
clearance label. This furnace shall not be installed directly on
carpeting, tile, or any combustible material other than wood
flooring.
LOCATION WITH RESPECT TO COOLING EQUIPMENT
The cooling coil must be installed parallel with, or on the
downstream side of, the furnace to avoid condensation in the heat
exchangers. When installed parallel with a furnace, dampers or
other means used to control the flow of air must prevent chilled air
from entering the furnace. If the dampers are manually operated,
they must be equipped with means to prevent operation of either
unit unless the damper is in the full-heat or full-cool position.
HAZARDOUS LOCATIONS
When the furnace is installed in a residential garage, it must be
installed so that the burners and ignition source are located at least
18 in. above the floor. Also, the furnace should be protected from
physical damage by vehicles. When a furnace is installed in public
garages, airplane hangars, or other buildings having hazardous
atmospheres, the unit must be installed in accordance with the
recommended good practice requirements of the National Fire
Protection Association, Inc.
Step 2—AIR FOR COMBUSTION AND VENTILATION
Provisions for adequate combustion and ventilation air must be
provided in accordance with Section 5.3, Air for Combustion and
Ventilation, of the National Fuel Gas Code, ANSI Z223.1-1992, or
applicable provisions of the local building codes.
Canadian installations must be installed in accordance with
CAN/CGA-B149 Installation Codes, and all authorities having
jurisdiction.
