58DP,DR Downflow Gas-Fired Natural-Draft Furnaces
58DP Series 150 and 160
58DR Series 130
Installation, Start-Up and Service Instructions
NOTE: Read the entire instructions before starting the installation.
INTRODUCTION
Before installing the furnace, refer to “Procedures for Natural-Draft Gas-Fired Furnaces” (packaged with the equipment) for information concerning combustion, venting, piping, and other standeird installation practices. Further reference is made to the current edition of the National Fuel Gas Code NFPA No. 54-1988/ANSI Z223.1-1988.
Reference should also be made to the regulations of the serving gas supplier and the local building, heating, plumb ing, or other codes in effect in the area in which the installa tion is made.
SAFETY CONSIDERATIONS
Installation and servicing of heating equipment can be haz ardous due to gas and electrical components. Only trained and qualified personnel should install, repair, or service heating equipment.
Untrained personnel can perform basic meuntenance func tions such as cleaning and replacing air filters. AU other operations must be performed by trained service personnel, when working on heating equipment, observe precautions in the literature, tags, and labels attached to or shipped with the unit and other safety precautions that may apply.
Follow all safety codes, including NFPA No. 54/ANSI Z223.1-1988, National Fuel Gas Code. Wear safety glasses and work gloves. Have fire extinguisher available during startup and adjustment procedures and service call.
Recomized safety information: This is the safety-alert sym bol A. When you see this symbol on the furnace and in instructions or manueils, be alert to the potential for per sonal injury.
Understand the signal word—DANGER, WARNING, or CAUTION. These words are used with the safety-alert sym bol. DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING on the other hand could result in personal injury or death. CAUTION is used to identify unsafe practices, which would result in minor personal injury or product and property damage.
Each furnace is shipped from the factory completely assem bled with multispeed direct-drive blower and wired ready for downflow indoor heating installation only. AU sizes feature a printed-circuit board control center with easy-to-read, 24volt terminal strip to ensure proper connections.

»■NOTE: The furnaces covered by these instructions are design-certified for use with the vent damper specified on the furnace rating plate. See instructions packaged with the vent deunper for its installation.
A CAUTION
Application of this furnace should 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.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

♦These dimensions appiy when a Model 28RC or RD Evaporator Coil cas ing is to be installed.
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. Return air temperature must not exceed a maximum of 85 degrees F DB.
A WARNING
Improper histaUation, adjustment, alteration, service, maintenance, or use can cause carbon monoxide poison ing, explosion, 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 Distributor 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 adhere to this warning can cause electrical shock, fire, personal injury, or death.

A CAUTION
Do not insteill furnace in a damp, corrosive, or contami nated atmosphere. Make sure all combustion and circu lating air requirements listed in “Procedures for Natured-Draft Gas-Fired Furnaces” are adhered to, in addition to all local codes and ordinances.
Do not use this furnace during construction when adhe sives, 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 with combustion air form acids which wiU cause corrosion of the heat exchangers and metal vent system. Some of these com pounds are paneling and dry wall adhesives, paints, thinners, masonry cleaning materials, and many other solvents commonly used in the construction process.
The design of the downflow gas-fired furnace is A.G.A. cer tified for installation on noncombustible flooring. The fur nace may be installed on combustible flooring when installed with the accessory downflow subbase. This furnace is for installation in alcoves, basements, closets, or utility rooms. This furnace fine is not A.G.A. design certified for installation in a mobile home, recreation vehicle, or outdoors.
Installation comprises the following:
*1. Inspection
*11. Location, Ventilation, and Air for Combustion *III. Gas Piping
*IV. Venting
V. Supply-Air Plenum Installation
VI. Electrical
VII. Sequence of Operation
VIII. Füter
IX. Startup and Adjustment
X. Care and Maintenance
*To perform these sections (or installation steps), refer to the appropriate sections of “Procedures for Natural-Draft Gas-Fired Furnaces” booklet packaged with this unit.
For accessory installation details, refer to the applicable installation hterature. Terminals EAC-1 and EAC-2 in the control box are for direct connection of an electronic air cleaner.
