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.

Step 1—LOCATION

GENERAL

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. Retum-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.

A WARNING

Improper installation, adjustment, alteration, service, mainte

nance, or use can cause carbon monoxide poisoning, explo

sion, fire, electrical shock, or other conditions which may

cause personal injury or property damage. Consult a qualified

installer, service agency, local gas supplier, or your distribu

tor or branch for information or assistance. The qualified

installer or agency must use only factory-authorized and

listed kits or accessories when modifying this product. A

failure to follow this warning can cause electrical shock, fire,

personal injury, or death.

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.

A CAUTION

Do not install furnace in a corrosive or contaminated atmo

sphere. Make sure all combustion and circulating air require

ments are met, in addition to all local codes and ordinances.

A CAUTION

Do not use this furnace during construction when adhesives,

sealers, and/or new carpets are being installed. If the furnace

is required during construction, use clean outside air for

combustion and ventilation. Compounds of chlorine and

fluorine, when burned in combustion air, form acids which

will cause corrosion of the heat exchangers and metal vent

systems. Some of these compounds are released from: pan

eling and dry wall adhesives, paints, thinners, masonry

cleaning materials, and many other solvents commonly used

in the construction process.

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.
